Backbone js setting header for get request - backbone.js

How can I set a header for my token to send GET request to an external url?
I don't want to override the Backbone.sync actually
I want to manually set it for fetching my collection
where should I put the header?
Specific question:
I want to send GET request and I have specific URL I should set the token for that how should I do that?

You can give custom headers in the headers parameter in the options to the collection's fetch method:
var ThingCollection = Backbone.Collection.extend({
url: '/things'
});
var thingCollection = new ThingCollection();
thingCollection.fetch({
headers: {
'Authorization': 'Basic NAME:PASSWORD'
}
});

AngularJS custom headers request

I am building an Ionic app, and trying to set custom headers for every GET request I do on the app.
This is the CustomHeaderController
angular.module('myHeader',[])
.controller('headerCtrl',['customHeader',function(customHeader){
var config = {headers: {
'Authorization': 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==',
'Accept': 'text/html;odata=verbose',
"X-Request-from" : "{{vm.data.os}}" }};
$http.get('http://localhost:8100, config); }])
At the moment when I inspect the page, I do not get any custom header, just the default one.
Any clues? Appreciate it! Cheers.
You need to use interceptor in this case with every http request.

send request without adding header in angular js

i'm trying to sending request to third party service. for that i need to delete default header 'x-access-token'. For that did like below
$http({
url: 'http://ip-api.com/json',
method: 'GET',
transformRequest: function(data, headersGetter) {
var headers = headersGetter();
delete headers['x-access-token'];
return headers;
}
}).then(function(res){
console.log(res);
},function(error){
console.log(error);
});
By following this link .
But i'm getting this error
TypeError: Cannot convert object to primitive value

"transformRequest" does not work the same way to remove headers for individual requests past angularjs 1.4 release .From the documentation its clear that we should be using "headers" instead
eg:
$http({method: 'GET',
url: "url",
headers: {
'header-name': undefined
}
}).success(function(data){console.log(data)});
The $http service config object allows you to override the http header send for a specific request. See config property headers.
To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, Use the headers property, setting the desired header to undefined.
NOTE: Set the desire header/headers to undefined like this, then it will not affect the global settings.
See example:
var req = {
method: 'POST',
url: 'http://example.com',
headers: {
'Content-Type': undefined
},
data: { test: 'test' }
}
$http(req).then(function(){...}, function(){...});
See more documentation.
This can take a list of headers or a function that return a list of headers. So for the non auth header request make a copy of the default headers remove the header you don't require and then make the request.
Hope this help well.

AngularJS $http.post server doesn't allow a request with method OPTIONS

I am trying to do a an HTTP POST to a server.
The data I have to send is a json object.
The problem is that $http.post in angular override the method with options.
I can make this config
.config(['$httpProvider', function ($httpProvider) {
//Reset headers to avoid OPTIONS request (aka preflight)
$httpProvider.defaults.headers.common = {};
$httpProvider.defaults.headers.post = {};
$httpProvider.defaults.headers.put = {};
$httpProvider.defaults.headers.patch = {};
}])
and changes from options to POST, but I can't set the content-type to "application/json", and I am getting a "415 Unsupported Media Type"
Thank you
$http.post in angular doesn't override the method with OPTIONS. It appear that you are trying to call api in different domain than the one your JS code come from. This is called Cross Domain. For such cases the browser performs preflight request with OPTIONS in order to see the returned headers. In your backend response you should add the header Access-Control-Allow-Origin: * for example. When the browser sees that header he performs the actual POST request.
More details here: https://developer.mozilla.org/en/docs/HTTP/Access_control_CORS
Hope this is helps!
Add
$httpProvider.defaults.headers.post['Content-Type'] = 'application/json';
But note this will set the Content-Type header globally.
If you need to set the content-type per call, you should use $http.post like
$http.post("/foo/bar", requestData, {
headers: { 'Content-Type': 'application/json'},
transformRequest: transform
}).success(function(responseData) {
//do stuff with response
});

AngularJS $resource not sending custom headers

I'm using angular and angular-resource version 1.1.5 and I'm using a $resource to make a request to a REST service. But it seems like the custom headers is not appended to the request. My definition is as below. Is there anything I did wrong?
myApp.factory('User', function($resource) {
var User = $resource('http://localhost\\:7017/mydomain/users/jack', { }, {
get: {
method: 'GET',
isArray: false,
headers: {'X-Requested-By':'abc'}
}
});
return User;
});
Read this to see how to configure default headers in one place: http://docs.angularjs.org/api/ng.$http
EDIT:
Your header must be included in Access-Control-Allow-Headers header in response to the OPTIONS request, which is sent automatically prior to your GET request.
You can modify the default headers inside the $httpProvider.
the headers are an object and separated intocommon, patch, post and put
so if you want to change the default for all your requests, just do a
$httpProvider.defaults.headers.put['Content-Type'] = 'application/json';
You have to call get method by using its name, i.e User.get(callback)
It seems that custom headers do not get sent when get method is called with User.query(callback)

ngResource Dynamic Header

I'm trying to make a request to an API service that has a dynamic 'authorization' header.
var domain = "http://www.externalapi.com",
actions = {
'login': {
method: 'POST'
},
'objects': {
method: 'GET',
headers: {
'Authorization': Request.getAuthHeader()
}
}
};
var requests = $resource(domain, {}, actions);
requests.objects();
Request is a service I've written that has a method that builds the auth header based on the api requirements, the has it returns is correct.
When looking at the request to domain, however, I see not 'Authorization' header...
I've also tried passing in a static string, still no header.
So the issue was my versions.
After updating Angular to 1.2.0rc1 I left my ngResource module at 1.0.8.
After updating both to 1.2.0rc1 (I assume 1.1.2 would work as well) I was able to assign headers from the actions object of $resource.
