I am trying to intercept POST requests using a serviceworker with Workbox. However the route does not seem to register. When online the request just goes through and nothing is logged. When offline the console logges an net::ERR_INTERNET_DISCONNECTED error. The request also does not seem to fall into the catchHandler.
service-worker.js
registerRoute(
({url}) => url.pathname.endsWith('detailScreen'),
({request, url}) => {
console.log('POST', request, url)
},
'POST')
setCatchHandler(async options => {
console.log(options.request, options.url)
return Response.error();
})
request:
https://test.com/admin/crm/relation/detailScreen
I have my micro-service developed using spring-boot and spring security and frontend is designed on react-hooks.
Now, while I am send some data to my micro-service using axios.post method, it send CORS preflight method i.e. options method because axios by default send content-type as application/json and application.json leads to send options request to server before any other request.
I have tried sending my request with different headers and content types as 'application/x-www-form-urlencoded' also I have used #cross-origin(*) at my server end.
const config = {
headers: {
'Content-Type': 'application/json'
}
}
const response = await axios.post(ps.user_ms_url+ps.user_login,
{
username:values.email,
password:values.password
// headers:{'tokenvalue':'token'}
},
config);
I expect my browser to send only post request to the server, for that I am ready to change my headers as well.
Any help will be appreciated. Thanks in advance!
I found the solution for my query. As I mentioned above, our browser sends preflight request (means options request) before any other request if our request is not simple (here simple means: if request contains content-type : application/json or custom headers etc) and if we are sending this request to some other domain/ URL.
And our axios.post method carries content-type as application/json by default, that's why, my browser was sending multiple requests (means preflight request before any other request).
Now, I have changed my request content-type to application/x-www-form-urlencoded by sending data as params, as shown below:
var params = new URLSearchParams();
params.append('username', values.email);
params.append('password', values.password);
const response = await axios.post(ps.user_ms_url+ps.user_login,
params);
And handling this request at backend using #ModelAttribute annotation (Spring-boot). So, keeping request simple can stop preflight requests.
You can avoid CORS preflight request by proxying the request. Add this in your webpack development config
devServer: {
port: process.env.PORT || 3000,
proxy: {
'/api': {
target: 'http:localhost:8080',
pathRewrite: { '^/api': '' },
changeOrigin: true,
},
},
}
This means your request to /api/users will forwarded to http://localhost:8080/users.
If you are using create-react-app. just add "proxy": "http://localhost:8080" to your package.json. Check more info here
This looks to be server side CORS issue. You have to allow domains to access resources by providing correct response headers.
You can look at adding CORS headers in spring boot. Refer to this link
Hope that helps!!!
After setting up Amazon API Gateway CORS as instructed, I still get the following error when send an Ajax POST request.
XMLHttpRequest cannot load https://-------.execute-api.us-west-2.amazonaws.com/--------. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://------.s3-website-us-west-2.amazonaws.com' is therefore not allowed access. The response had HTTP status code 400.
I'm using Amazon S3 to host the website, which does not support web script so I can't use python or php to fix this.
I'd really appreciate any help.
Could it be that you're using Lambda-proxy integration and your Lambda is not returning those headers? If that's the case, you have to add those headers yourself.
This is how I use to create the response that I return using callback(null, response).
function createResponse(statusCode, body) {
const headers = {
'Access-Control-Allow-Origin': '*',
}
return {
headers,
statusCode,
body: body ? JSON.stringify(body) : undefined,
}
}
I want to post a message to slack on x channel
I need to send the following x parameters
how do I send the following parameters to a website
"channel": "XXXXX",
"token": "token",
"text": "text"
Add your parameters to the end of Slack's chat.postMessage endpoint like this:
http://slack.com/api/chat.postMessage?token=XXX&channel=XXX&text=XXX
Then make a GET request to that URL to post your message. Personally I'd suggest doing this as a Node application and using the request package obtained via npm. Makes it very easy.
Post message to Slack in a Node App
Create a new node project and then change to that folder on the command line
On the command line type npm install -g request to install the request module for your project
Inside the index.js file (or wherever you plan on calling the API) do as follows:
//Import request module
var request = require('request');
//Replace your token, channelID and text here
var path_to_call = 'http://slack.com/api/chat.postMessage?token=XXX&channel=XXX&text=XXX';
request(path_to_call, function(error, response, body) {
if (!error && response.statusCode == 200) {
console.log('Success');
} else {
console.log(error);
}
});
If you just want to post messages I would recommend to use an Incoming Webhook. They are specifically designed for that purpose and easier to use than API calls.
An Incoming webhook is a custom URL that you can create for your Slack team and then use to send messages into any channel. For sending a message you only need to submit your message in JSON format along with some parameters as POST request to your webhook URL.
If you are using PHP scripting on your website then you best use CURL for the call.
Check out the documentation for details on how to use it.
var url = "https://slack.com/api/chat.postMessage";
var auth_token = auth_token; //Your Bot's auth token
var headers = {
"Authorization": "Bearer " + auth_token,
"Content-Type" : "application/json"
}
var body = {
channel: userSlackId, // Slack user or channel, where you want to send the message
text: "Your text goes here."
}
request.post({
"url": url,
"headers": headers,
"body": JSON.stringify(body)
}, (err, response, body) => {
if (err) {
reject(err);
}
console.log("response: ", JSON.stringify(response));
console.log("body: ",body);
});
You have to set headers as Authorization, and add Bearer before your token as it is mentioned in slack docs. Also, send user/channel in body. Here I'm providing the link for the same for your reference https://api.slack.com/methods/chat.postMessage#channels . Hope this helps.
Not sure which language you're using, but if using Postman to test, you can try the following format.
raw Postman request
POST /api/chat.postMessage HTTP/1.1
Host: slack.com
Content-Type: application/json
Cache-Control: no-cache
{
"text": "This is a line of text.\nAnd this is another one.",
"token": "XXXX",
"channel": "XXXX",
}
Is it at all possible to download a file upon an ajax request?
Does it matter if it's same domain / cross domain?
I know it can be done upon redirecting the browser to a URL and setting relevant headers, but was wondering if it can be done when doing an ajax request.
I'm POSTing JSON as the Request Payload to a URL and based on the content of the JSON, I want to send back a specific file.
client.post(url, body: request, headers:{"Content-Type":"application/json"}).then((res) {
if (res.statusCode == 200) {
if ("application/json" == res.headers["content-type"]) {
// parse JSON here
} else {
// download the content if Content-Disposition is set
}
}
}).whenComplete(() {
client.close();
}).catchError((exception, stacktrace) {
print(exception);
print(stacktrace);
showErrorMessage("An Error Occurred");
});
I can see the the correct headers coming back for downloading a PDF, but it's not doing anything if I receive these headers via an AJAX response.
Update - clarifying:
If you click this link, it will do a GET request to Github and download the file: https://github.com/dartsim/dart/archive/master.zip
I'm trying to download the file using a POST request via Dart's BrowserClient.post.
