We have a site example.com behind ssl that runs a page with ApplePay.
We've got a server side that returns a Merchant Session that looks like the following:
{"epochTimestamp":1581975586106,"expiresAt":1581979186106,"merchantSessionIdentifier":"SSH8E666B0...","nonce":"1239e567","merchantIdentifier":"...8557220BAF491419A...","domainName":"example.com","displayName":"ApplePay","signature":"...20101310f300d06096086480165030402010500308..."}
We receive this response in session.onvalidatemerchant as a string and convert it to a Json Object and pass to session.completeMerchantValidation.
As a result we get the following error:
Code: "InvalidAccessError"
Message: "The object does not support the operation or argument"
We run the following code on our page:
.....
session.onvalidatemerchant = (event) => {
const validationURL = event.validationURL;
getApplePaySession(validationURL).then(function (response) {
try {
let resp = JSON.parse(response);
session.completeMerchantValidation(resp);
} catch (e) {
console.error(JSON.stringify(e));
}
});
};
....
Additional questions:
Is the object described above a "correct" Merchant Session opaque that needs to be passed to completeMerchantValidation or it's missing some fields?
Is this object needs to be passed as is or it needs to be base64 encoded?
Does it need to be wrapped into another object?
Any help or lead is greatly appreciated.
In Cypress, it is well-documented that you can alias specific network requests, which you can then "wait" on. This is especially helpful if you want to do something in Cypress after a specific network request has fired and finished.
Example below from Cypress documentation:
cy.server()
cy.route('POST', '**/users').as('postUser') // ALIASING OCCURS HERE
cy.visit('/users')
cy.get('#first-name').type('Julius{enter}')
cy.wait('#postUser')
However, since I'm using GraphQL in my app, aliasing no longer becomes a straightforward affair. This is because all GraphQL queries share one endpoint /graphql.
Despite it not being possible to differentiate between different graphQL queries using the url endpoint alone, it is possible to differentiate graphQL queries using operationName (refer to following image).
Having dug through the documentation, there doesn't appear to be a way to alias graphQL endpoints using operationName from the request body. I'm also returning the operationName (yellow arrow) as a custom property in my response header; however, I haven't managed to find a way to use it to alias specific graphQL queries either.
FAILED METHOD 1: This method attempts to use the purple arrow shown in image.
cy.server();
cy.route({
method: 'POST',
url: '/graphql',
onResponse(reqObj) {
if (reqObj.request.body.operationName === 'editIpo') {
cy.wrap('editIpo').as('graphqlEditIpo');
}
},
});
cy.wait('#graphqlEditIpo');
This method doesn't work since the graphqlEditIpo alias is registered at runtime and as such, the error I receive is as follows.
CypressError: cy.wait() could not find a registered alias for: '#graphqlEditIpo'. Available aliases are: 'ipoInitial, graphql'.
FAILED METHOD 2: This method attempts to use the yellow arrow shown in image.
cy.server();
cy.route({
method: 'POST',
url: '/graphql',
headers: {
'operation-name': 'editIpo',
},
}).as('graphql');
cy.wait('graphql');
This method doesn't work because the headers property in the options object for cy.route is actually meant to accept response headers for stubbed routes per the docs. Here, I'm trying to use it to identify my specific graphQL query, which obviously won't work.
Which leads me to my question: How can I alias specific graphQL queries/mutations in Cypress? Have I missed something?
The intercept API introduced in 6.0.0 supports this via the request handler function. I used it in my code like so:
cy.intercept('POST', '/graphql', req => {
if (req.body.operationName === 'queryName') {
req.alias = 'queryName';
} else if (req.body.operationName === 'mutationName') {
req.alias = 'mutationName';
} else if (...) {
...
}
});
Where queryName and mutationName are the names of your GQL operations. You can add an additional condition for each request that you would like to alias. You can then wait for them like so:
// Wait on single request
cy.wait('#mutationName');
// Wait on multiple requests.
// Useful if several requests are fired at once, for example on page load.
cy.wait(['#queryName, #mutationName',...]);
The docs have a similar example here: https://docs.cypress.io/api/commands/intercept.html#Aliasing-individual-requests.
This works for me!
Cypress.Commands.add('waitForGraph', operationName => {
const GRAPH_URL = '/api/v2/graph/';
cy.route('POST', GRAPH_URL).as("graphqlRequest");
//This will capture every request
cy.wait('#graphqlRequest').then(({ request }) => {
// If the captured request doesn't match the operation name of your query
// it will wait again for the next one until it gets matched.
if (request.body.operationName !== operationName) {
return cy.waitForGraph(operationName)
}
})
})
Just remember to write your queries with unique names as posible, because the operation name relies on it.
If 'waiting' and not 'aliasing' in itself is the main purpose, the easiest way to do this, as I've encountered thus far, is by aliasing the general graphql requests and then making a recursive function call to 'wait' targeting the newly created alias until you find the specific graphql operation you were looking for.
e.g.
Cypress.Commands.add('waitFor', operationName => {
cy.wait('#graphqlRequest').then(({ request }) => {
if (request.body.operationName !== operationName) {
return cy.waitFor(operationName)
}
})
})
This of course have its caveats and may or may not work in your context. But it works for us.
I hope Cypress enables this in a less hacky way in the future.
PS. I want to give credit to where I got the inspiration to this from, but it seemt to be lost in cyberspace.
Since I was having the same issue and I did not find a real solution for this problem I combined different options and created a workaround that solves my problem. Hopefully this can help someone else too.
I do not really 'wait' for the request to be happen but I catch them all, based on **/graphql url and match the operationName in the request. On a match a function will be executed with the data as parameter. In this function the tests can be defined.
graphQLResponse.js
export const onGraphQLResponse = (resolvers, args) => {
resolvers.forEach((n) => {
const operationName = Object.keys(n).shift();
const nextFn = n[operationName];
if (args.request.body.operationName === operationName) {
handleGraphQLResponse(nextFn)(args.response)(operationName);
}
});
};
const handleGraphQLResponse = (next) => {
return (response) => {
const responseBody = Cypress._.get(response, "body");
return async (alias) => {
await Cypress.Blob.blobToBase64String(responseBody)
.then((blobResponse) => atob(blobResponse))
.then((jsonString) => JSON.parse(jsonString))
.then((jsonResponse) => {
Cypress.log({
name: "wait blob",
displayName: `Wait ${alias}`,
consoleProps: () => {
return jsonResponse.data;
}
}).end();
return jsonResponse.data;
})
.then((data) => {
next(data);
});
};
};
};
In a test file
Bind an array with objects where the key is the operationName and the value is the resolve function.
import { onGraphQLResponse } from "./util/graphQLResponse";
describe("Foo and Bar", function() {
it("Should be able to test GraphQL response data", () => {
cy.server();
cy.route({
method: "POST",
url: "**/graphql",
onResponse: onGraphQLResponse.bind(null, [
{"some operationName": testResponse},
{"some other operationName": testOtherResponse}
])
}).as("graphql");
cy.visit("");
function testResponse(result) {
const foo = result.foo;
expect(foo.label).to.equal("Foo label");
}
function testOtherResponse(result) {
const bar = result.bar;
expect(bar.label).to.equal("Bar label");
}
});
}

Used the blob command from glebbahmutov.com
This is what you're looking for (New in Cypress 5.6.0):
cy.route2('POST', '/graphql', (req) => {
if (req.body.includes('operationName')) {
req.alias = 'gqlMutation'
}
})
// assert that a matching request has been made
cy.wait('#gqlMutation')
Documentation:
https://docs.cypress.io/api/commands/route2.html#Waiting-on-a-request
I hope that this helps!
I used some of these code examples but had to change it slightly to add the onRequest param to the cy.route and also add the date.Now (could add any auto incrementer, open to other solutions on this) to allow multiple calls to the same GraphQL operation name in the same test. Thanks for pointing me in the right direction!
Cypress.Commands.add('waitForGraph', (operationName) => {
const now = Date.now()
let operationNameFromRequest
cy.route({
method: 'POST',
url: '**graphql',
onRequest: (xhr) => {
operationNameFromRequest = xhr.request.body.operationName
},
}).as(`graphqlRequest${now}`)
//This will capture every request
cy.wait(`#graphqlRequest${now}`).then(({ xhr }) => {
// If the captured request doesn't match the operation name of your query
// it will wait again for the next one until it gets matched.
if (operationNameFromRequest !== operationName) {
return cy.waitForGraph(operationName)
}
})
})
to use:
cy.waitForGraph('QueryAllOrganizations').then((xhr) => { ...
This is how I managed to differentiate each GraphQL request. We use cypress-cucumber-preprocessor so we have a common.js file in /cypress/integration/common/ where we can call a before and beforeEach hook which are called before any feature file.
I tried the solutions here, but couldn't come up with something stable since, in our application, many GraphQL requests are triggered at the same time for some actions.
I ended up storing every GraphQL requests in a global object called graphql_accumulator with a timestamp for each occurence.
It was then easier to manage individual request with cypress command should.
common.js:
beforeEach(() => {
for (const query in graphql_accumulator) {
delete graphql_accumulator[query];
}
cy.server();
cy.route({
method: 'POST',
url: '**/graphql',
onResponse(xhr) {
const queryName = xhr.requestBody.get('query').trim().split(/[({ ]/)[1];
if (!(queryName in graphql_accumulator)) graphql_accumulator[queryName] = [];
graphql_accumulator[queryName].push({timeStamp: nowStamp('HHmmssSS'), data: xhr.responseBody.data})
}
});
});
I have to extract the queryName from the FormData since we don't have (yet) the key operationName in the request header, but this would be where you would use this key.
commands.js
Cypress.Commands.add('waitGraphQL', {prevSubject:false}, (queryName) => {
Cypress.log({
displayName: 'wait gql',
consoleProps() {
return {
'graphQL Accumulator': graphql_accumulator
}
}
});
const timeMark = nowStamp('HHmmssSS');
cy.wrap(graphql_accumulator, {log:false}).should('have.property', queryName)
.and("satisfy", responses => responses.some(response => response['timeStamp'] >= timeMark));
});
It's also important to allow cypress to manage GraphQL requests by adding these settings in /cypress/support/index.js:
Cypress.on('window:before:load', win => {
// unfilters incoming GraphQL requests in cypress so we can see them in the UI
// and track them with cy.server; cy.route
win.fetch = null;
win.Blob = null; // Avoid Blob format for GraphQL responses
});
I use it like this:
cy.waitGraphQL('QueryChannelConfigs');
cy.get(button_edit_market).click();
cy.waitGraphQL will wait for the latest target request, the one that will be stored after the call.
Hope this helps.
Somewhere else this method was suggested.
Btw it all becomes a bit easier once you migrate to Cypress v5.x and make use of the new route (route2) method.
Our use case involved multiple GraphQL calls on one page. We had to use a modified version of the responses from above:
Cypress.Commands.add('createGql', operation => {
cy.route({
method: 'POST',
url: '**/graphql',
}).as(operation);
});
Cypress.Commands.add('waitForGql', (operation, nextOperation) => {
cy.wait(`#${operation}`).then(({ request }) => {
if (request.body.operationName !== operation) {
return cy.waitForGql(operation);
}
cy.route({
method: 'POST',
url: '**/graphql',
}).as(nextOperation || 'gqlRequest');
});
});
The issue is that ALL GraphQL requests share the same URL, so once you create a cy.route() for one GraphQL query, Cypress will match all the following GraphQL queries to that. After it matches, we set cy.route() to just a default label of gqlRequest or the next query.
Our test:
cy.get(someSelector)
.should('be.visible')
.type(someText)
.createGql('gqlOperation1')
.waitForGql('gqlOperation1', 'gqlOperation2') // Create next cy.route() for the next query, or it won't match
.get(someSelector2)
.should('be.visible')
.click();
cy.waitForGql('gqlOperation2')
.get(someSelector3)
.should('be.visible')
.click();
I'm working on a Cloud Code function that uses facebook graph API to retrieve users profile picture. So I have access to the proper picture URL but I'm not being able to acreate a Parse.File from this URL.
This is pretty much what I'm trying:
Parse.Cloud.httpRequest({
url: httpResponse.data["attending"]["data"][key]["picture"]["data"]["url"],
success: function(httpImgFile)
{
var imgFile = new Parse.File("file", httpImgFile);
fbPerson.set("profilePicture", imgFile);
},
error: function(httpResponse)
{
console.log("unsuccessful http request");
}
});
And its returning the following:
Result: TypeError: Cannot create a Parse.File with that data.
at new e (Parse.js:13:25175)
at Object.Parse.Cloud.httpRequest.success (main.js:57:26)
at Object.<anonymous> (<anonymous>:842:19)
Ideas?
I was having trouble with this exact same problem right now. For some reason this question is already top on Google results for parsefile from httprequest buffer!
The Parse.File documentation says
The data for the file, as 1. an Array of byte value Numbers, or 2. an Object like { base64: "..." } with a base64-encoded String. 3. a File object selected with a file upload control. (3) only works in Firefox 3.6+, Safari 6.0.2+, Chrome 7+, and IE 10+.
I believe for CloudCode the easiest solution is 2. The thing that was tripping me earlier is that I didn't notice it expects an Object with the format { base64: {{your base64 encoded data here}} }.
Also Parse.Files can only be set to a Parse.Object after being saved (this behaviour is also present on all client SDKs). I strongly recommend using the Promise version of the API as it makes much easier to compose such asynchronous operations.
So the following code will solve your problem:
Parse.Cloud.httpRequest({...}).then(function (httpImgFile) {
var data = {
base64: httpImgFile.buffer.toString('base64')
};
var file = new Parse.File("file", data);
return file.save();
}).then(function (file) {
fbPerson.set("profilePicture", file);
return fbPerson.save();
}).then(function (fbPerson) {
// fbPerson is saved with the image
});
I am trying to load sample data from a REST API source that return XML inside my emberjs app but I am facing two problems:
The model name is always in plural, so instead of /sqlrest/CUSTOMER/3/ the code always generate /sqlrest/CUSTOMERS/3/
I know that DS.RESTAdaptor expects by default JSON format so I was wondering is there any way I can still get XML format and may be convert to JSON?
Thanks
Code I am using is as follows (This code I found in one of SO replies and altered to match the URL I am trying to access):
App.store = DS.Store.create({
revision: 11,
adapter: DS.RESTAdapter.create({
namespace: "sqlrest",
url: "http://www.thomas-bayer.com",
plurals: {
'customer': 'customer'
},
ajax: function (url, type, hash) {
hash.url = url;
hash.type = type;
hash.dataType = 'jsonp';
hash.contentType = 'application/json; charset=utf-8';
hash.context = this;
if (hash.data && type !== 'GET') {
hash.data = JSON.stringify(hash.data);
}
jQuery.ajax(hash);
},
})
});
and in route:
App.CustomersRoute = Ember.Route.extend({
model: function() {
//return App.Customer.find();
//New
return App.Customer.find(18);
}
});
Maybe you could look at ember-restless which allows XML consumption:
https://github.com/endlessinc/ember-restless
For pluralization, take a look in here:
https://github.com/emberjs/data/blob/v1.0.0-beta.6/packages/ember-data/lib/adapters/rest_adapter.js#L476
The only thing is, obviously if you're going to use ember-restless, you'll need to find the relative point in there that you need to override in a similar way (if it's possible to customize endpoints).
I'm having difficulty accessing requestJSON on a jQuery $.ajax object outside of the success callback. If I do:
var ajax_request = $.ajax({
dataType: 'json',
contentType: 'application/json'
});
console.log(ajax_request.responseJSON);
// this results in `undefined`
How can I access the responseJSON without adding a .success() callback? If I inspect ajax_request in Firebug, I can see the responseJSON property, and the data I expect, but I can't access it via:
ajax_request.responseJSON
More specifically, I'm building an SPA using Sammy and Knockout. In some routes, I need to be able to get JSON from cache, and if it doesn't exist, get the value from a service call and then set it into cache:
var cached_json = storage.fetch('cached_json', function() {
// make service call
return $.getJSON(url);
});
event_context.render('template.tpl', {'json': cached_json}).appendTo('#my-target');
But, of course, calling storage.fetch doesn't cause the rest of the code to pause until $.getJSON is complete. This is the part I can't quite figure out how to structure.
here's how i would implement it
responseJSON = "";
$.get("myurl.php",function(jdata){
responseJSON = jdata;
},"json");
i like to see the ajax method at a glace, but in your case you can do the same by
....
success : function(jdata){ responseJSON = jdata; }
....
PS: i believe that initializing the blank responseJSON is not required since any variable without var is in global scope, but it would help for clarity
I ended up solving this by creating a deferred object that gets or creates the value I need:
function get_or_create_cache(storage, key, service_endpoint) {
return $.Deferred(function(deferred) {
var c = storage.get(key);
if (c === null || c === undefined) {
$.when(jsonp_service_request(service_endpoint)).done(function(json) {
storage.set(key, json);
deferred.resolve(json);
});
}
else {
deferred.resolve(c);
}
}).promise();
}
In this function, storage refers to a Sammy.Storage instance. jsonp_service_request is a local function that returns a jsonp response, taking into account the location.hostname for local development, where I'm pointing to local.json files, or a remote environment, where I'm calling into an actual API. jsonp_service_request returns an $.ajax function.
Then in my Sammy route, I can do:
this.get('#/', function(event_context) {
$.when(get_or_create_cache(storage, 'my-cache-key', 'service-endpoint'))
.then(function(json) {
event_context.render('my-template.template', {'value-name': json})
.appendTo('#my-target');
});
});
