AngularJS在$ http.get中添加标题 [英] AngularJS Adding a header to the $http.get

问题描述

我正在尝试添加授权"标头，其中包含用于将来的HTTP请求的令牌.检索令牌似乎很好，但是在发出get请求时，它会失败，并显示一条未经授权的错误消息.在检查请求标头之后，请求标头在请求块中不存在...

I'm trying to add the 'Authorization' header containing a token for future HTTP request. Retrieval of the token seems to be fine however when making a get request it fails with an Unauthorized error message. After checking the request headers Authorization header does not exist in the request block...

window.crUtil = /*window.crUtil ||*/ (function() {

    // Angular Services
    var $injector = angular.injector(['ng']);
    var $http = $injector.get('$http');


    // getting the CFF data
    function get_data() {
    		getJWTAWS();
        var url = '/AWS/getDATA/555';
				console.log('AUTH header before call: ' + $http.defaults.headers.common.Authorization);
        $http.get(url,httpHeader).then(function successCallback(response) {
            var data = response.data;
            var cff = initCff();
            alert(data.itemId);
            
        }, function errorCallback(response) {
            initCff();
            alert("Error while getting data ");
        });

    }
		
    function getJWTAWS() {
        var httpConfig = {
            cache: true, 
            params: {}
        };

        $http.get('/AWS/token', httpConfig).then(
            function(response) {
                if (response.data.accessToken) {
                    // add jwt token to auth header for all requests made by the $http service

                    $http.defaults.headers.common.Authorization = response.data.tokenType + ' ' + response.data.accessToken;
                }
            },
            function(error) {
                alert('jwt token could not be retrieved.');
            }
        );
    }


})();

var result = util.get_data();
console.log ('called search function ' + result);

函数getToken()返回一个值，但是由于我是该主题的新手，所以我不确定将令牌添加到标头的方式是否正确. 您能否建议在请求中包含标头的正确方法.我也试图将其添加到get请求中，例如 $ http.get(URL，httpHeaders)... 但它也不起作用.

Function getToken() returns a value but as I'm new on that topic I'm not quite sure if the way I added the token to the headers is proper. Could you please advise on the proper way to include the headers in the request. I also tried to add it to the get request like $http.get(URL,httpHeaders)... but it also didn't work.

推荐答案

我不确定您是否完全了解您的问题，因为您没有提供您所称的内容

I'm not sure I understand your problem completely as you did not provide what you call

httpConfig

httpConfig

如果您在声明标头方面很费力，请尝试发出以下get请求:

If you're struggling to declare the headers, try making the get request like this:

$http({
  method: 'GET',
  url: YOUR_URL,
  headers: {
    'Content-Type': 'application/json',
    'Authorization': AUTH_STRING_HERE
  }
}).then(function (response) { ... });

您可以在其中的标题对象中添加任何您喜欢的标题.

You can add any headers you like in the headers object there.
