I have an extension that is checking response in http-on-examine-response listener. In the listener it is possible change the headers via httpChannel, and via nsITraceableChannel we can change response content.
But how to change response code (for example from 407 to 200) in the http-on-examine-response listener?
Some code:
const { Ci, Cu, Cc, Cr } = require('chrome');
Cu.import('resource://gre/modules/Services.jsm');
var observer = {
observe: function(aSubject, aTopic, aData) {
if (aTopic == 'http-on-examine-response') {
console.log('we are in observer http-on-examine-response');
var httpChannel = aSubject.QueryInterface(Ci.nsIHttpChannel);
if(httpChannel.responseStatus == 407){
httpChannel.responseStatus = 200; // <-- this is not working
}
}
}
};
Services.obs.addObserver(observer, 'http-on-examine-response', false);
exports.onUnload = function (aData, aReason) {
Services.obs.removeObserver(observer, 'http-on-examine-response');
};

I am trying to get multiple values from my ESP32 and display them on a webpage without refresh usign ajax. So far I have found only examples online that update only one vairable (see example below), but how can I update more than one variable?
code from my index.h file:
<script>
setInterval(function() {
// Call a function repetatively with regular interval
getData();
}, 500); //500mSeconds update rate
function getData() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("ADCValue").innerHTML =
this.responseText;
}
};
xhttp.open("GET", "readADC", true);
xhttp.send();
}
</script>
in this sample ADCValue is written with the responsetext, but what if I have multiple values coming in?
In esp32 server you need to response JSON message. Something like this
{"var1": "value1", "var1": "value2"}
Example code in ESP32
// Send headers
client.println("HTTP/1.1 200 OK");
client.println("Content-type: application/json");
client.println();
// Send http body
String var1 = "value1";
String var2 = "value2";
String jresp = "{\"var1\":\""+var1+"\",\"var1\":\""+var2+"\"}";
client.println(jresp);
client.println();
Finally, in your JS code, you can do something like this
xhttp.onreadystatechange = function() {
if (http.readyState == 4) {
try {
var msg = JSON.parse(http.responseText);
var var1 = msg.var1;
var var2 = msg.var2;
// You got 2 values above
} catch (e) {}
}
}

This code takes the input from sender but even if sender has application ID it shows the same message.
In my angular application, I am trying to write a test case for following scenario but getting error 'Expected spy reinvite to have been called.'. Im testing on "jasmine-core: ^2.5.2 and "karma: ^1.3.0". I have written similar test cases and they passed without error.
In my controller file:
function reinvite() {
var emailsToReInvite = $j.map($scope.settingsData.userSettingsDetails, function(user) {
if(user.reInviteChecked){
return user.email;
}
});
if (emailsToReInvite.length >= 1) {
var invitation = { invitees: emailsToReInvite, listId: listId};
invitation = JSON.stringify(invitation);
inviteCollaboratorsModalDataService.reinvite(invitation).then(
function success(response) {
if(response.data.messages[0].code == 214){
$scope.showReinviteSuccess = true;
}
}else{
$scope.showReinviteSuccess = false;
}
}
);
}
}
And my spec file:
describe('settingsModalController', function() {
var controllerUnderTest = "settingsModalController";
var controllerResolver, rootScope, injector, $scope, inviteCollaboratorsModalDataService
beforeEach(function(){
angular.mock.module('sharedListApp');
inject(function($controller, $rootScope, $injector){
controllerResolver = $controller;
rootScope = $rootScope;
injector = $injector;
});
$scope = rootScope.$new();
inviteCollaboratorsModalDataService = injector.get('uiCommon.inviteCollaboratorsModalDataService');
});
it("should send re-invitation mail to selected users successfully", shouldReinviteSelectedUsers);
function shouldReinviteSelectedUsers() {
var $q = injector.get('$q');
$scope.settingsData = {
userSettingsDetails: [{email: 'abc#xyz.com'}]
};
var data = {
messages: [ { code: 214 }],
invite: {
invitation: $scope.settingsData
}
};
var response = { data: data };
var mockResult = new $q.defer();
mockResult.resolve(response);
spyOn(inviteCollaboratorsModalDataService, 'reinvite').and.returnValue(mockResult.promise);
controllerResolver(controllerUnderTest, { $scope: $scope });
$scope.reinvite();
$scope.showReinviteSuccess = true;
$scope.$apply();
expect(inviteCollaboratorsModalDataService.reinvite).toHaveBeenCalled();
expect($scope.showReinviteSuccess).toBe(true);
}
}
What am i doing wrong or what am i missing? Thanks in advance.
Ok, so i missed one variable to add in $scope.settingsData in my spec file which was why my spec code was not parsing into the first 'if' loop of the controller. Got it working by adding 'reInviteChecked: true' in:
$scope.settingsData = {
userSettingsDetails: [{email: 'abc#xyz.com', reInviteChecked: true}]
};

Can you tell me how to squash that error please?
It looks like the offending line is setTimeout("quickfilter_mafiaafire.redirectToAnotherUrl()",1500);
The setTimeout function can take a string (which then essentially gets eval'd) or a function (which gets called). Using a string is not recommended, for all the same reasons that using eval is not recommended. See https://developer.mozilla.org/en/DOM/window.setTimeout
In this case, the simplest fix would be to change it to setTimeout(function() { quickfilter_mafiaafire.redirectToAnotherUrl(); },1500);
XmlHttpRequest works through callbacks. So how can I return a value? I tried to set a global variable, but that doesn't seem to be working.
var response = null; // contains the most recent XmlHttpRequest response
// loads the info for this username on the page
function loadUsernameInfo(username) {
getUserInfo(username);
var profile = response;
if (profile) {
// do stuff
}
else {
indicateInvalidUsername(username);
}
}
getUserInfo() can't return a result, because of the callback:
function getUserInfo(username) {
var request = createRequest();
request.onreadystatechange = userObjFromJSON;
var twitterURL = "http://twitter.com/users/show/" + escape(username) + ".json";
var url = "url.php?url=" + twitterURL;
request.open("GET", url, true);
request.send(null);
}
The callback:
function userObjFromJSON() {
if (this.readyState == 4) {
alert(this.responseText);
response = this.responseText;
}
}
How can I get the response back to loadUsernameInfo()?
You can do synchronous requests, though it is not recommended - the A is for Asynchronous... But the general idea to implement this correctly would be:
var response = null; // contains the most recent XmlHttpRequest response
// loads the info for this username on the page
function loadUsernameInfo(username) {
getUserInfo(username, onLoadUsernameComplete);
}
function getUserInfo(username, oncomplete) {
var request = createRequest();
request.__username = username;
request.onreadystatechange = oncomplete;
var twitterURL = "http://twitter.com/users/show/" + escape(username) + ".json";
var url = "url.php?url=" + twitterURL;
request.open("GET", url, true);
request.send(null);
}
function onLoadUsernameComplete(req) {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
var profile = req.responseXML;
if (profile) {
// do stuff
}
else {
indicateInvalidUsername(req.__username);
}
}
}
}
