javascript - 如何在 Angular JS 中使用 JWT 调用 REST API

Question

我在 webapi 中创建了一个带有基于 jwt token 的身份验证的 Web API。我想用 Angular js $http 调用 html 页面中的其余 api。我尝试过，但显示请求失败。我从 postman 工具获得响应，但在网页中。不知道如何在 header 中传递不记名 token 。

postman 请求

GET /api/mp/dashboard HTTP/1.1
Host: localhost:55417
Authorization: Bearer eyJhbGciOiJodHRwOi8vd3d3LnczLm9yZy8yMDAxLzA0L3htbGRzaWctbW9yZSNobWFjLXNoYTI1NiIsInR5cCI6IkpXVCJ9.eyJodHRwOi8vc2NoZW1hcy54bWxzb2FwLm9yZy93cy8yMDA1LzA1L2lkZW50aXR5L2NsYWltcy9uYW1lIjoiQWRtaW4iLCJleHAiOjE1NjA5NDcyMzMsImlzcyI6Im15c2l0ZS5jb20iLCJhdWQiOiJteXNpdGUuY29tIn0.SMTy2H5vmWWUgCytHEHfT847ipE2hCzk0wvP2Of60Uk

Angular js代码

var app = angular.module('myApp', []);
app.controller('myCtrl', function ($scope, $http) {                 
    $http.get("http://ip_address:3393/api/mp/dashboard", {
        headers: { 'Authorization': 'Bearer eyJhbGciOiJodHRwOi8vd3d3LnczLm9yZy8yMDAxLzA0L3htbGRzaWctbW9yZSNobWFjLXNoYTI1NiIsInR5cCI6IkpXVCJ9.eyJodHRwOi8vc2NoZW1hcy54bWxzb2FwLm9yZy93cy8yMDA1LzA1L2lkZW50aXR5L2NsYWltcy9uYW1lIjoiQWRtaW4iLCJleHAiOjE1NjA5NDcyMzMsImlzcyI6Im15c2l0ZS5jb20iLCJhdWQiOiJteXNpdGUuY29tIn0.SMTy2H5vmWWUgCytHEHfT847ipE2hCzk0wvP2Of60Uk' }
    })
    .then(function (response) {
        $scope.myWelcome = response.data;
        $scope.fridgetemp = $scope.myWelcome.fridge_temp;       
    });
});

尝试此 Http get 调用，对于 header ，您必须在名为 Content-Type : 'application/json' 的对象中传递一个字段以及授权

$http({
            method: "GET",
            url: 'http://ip_address:3393/api/mp/dashboard',
            headers: {
            'Content-Type': 'application/json',
            'Authorization': 'Bearer eyJhbGciOiJodHRwOi8vd3d3LnczLm9yZy8yMDAxLzA0L3htbGRzaWctbW9yZSNobWFjLXNoYTI1NiIsInR5cCI6IkpXVCJ9.eyJodHRwOi8vc2NoZW1hcy54bWxzb2FwLm9yZy93cy8yMDA1LzA1L2lkZW50aXR5L2NsYWltcy9uYW1lIjoiQWRtaW4iLCJleHAiOjE1NjA5NDcyMzMsImlzcyI6Im15c2l0ZS5jb20iLCJhdWQiOiJteXNpdGUuY29tIn0.SMTy2H5vmWWUgCytHEHfT847ipE2hCzk0wvP2Of60Uk'
            },
            data: '' //this field depends on coder.
        })
        .then(function (response) {
                //your success result code handling 
            },
            function (error) {
              //your error handling code
                }
            });
