Question

我有这个邮递员的请求，但是有些角度等同于它的工作原理

我希望得到post man中确切请求的响应，如下所示。在邮递员它给我我需要的东西，但不能让它在角度

var settings = {
      "async": true,
      "crossDomain": true,
      "url": "http://197.157.93.110/Apiv1/token",
      "method": "POST",
      "headers": {
        "cache-control": "no-cache",
        "postman-token": "c76c4b6a-9a69-23dd-0171-8e6cbacd7944",
        "content-type": "application/x-www-form-urlencoded"
      },
      "data": {
        "grant_type": "password",
        "UserName": "user1",
        "Password": "password"
      }
    }

    $.ajax(settings).done(function (response) {
      console.log(response);
    });

我的角度代码看起来像这样

services.factory('documentService', ['$http', function($http){
            return {
                    getToken:function(grant_type,user,password){
                        return $http({
                                method:"POST",
                                url:"http://197.156.93.110/Apiv1/token",
                                headers: {
                                            "cache-control": "no-cache",
                                            "content-type": "application/x-www-form-urlencoded"
                                  },
                                data: {
                                    "grant_type": grant_type,
                                    "UserName": user,
                                    "Password": password
                                  }         
                        });
                    }
                ,

我收到错误错误请求代码400

我以后在我的代码中使用它来调用这样的承诺

documentService.getToken("password","user1","password").success(function(token){
        $scope.access_token=token.access_token;
        $scope.userName=token.userName;
        $scope.token_type=token.token_type;
        $scope.message={"message":"success"};
                $interval(function () {
                    $scope.message = "";
                }, 10000);
                //call get documents if only access token is success


    }).error(function(err){
        $scope.message=err;
        $interval(function () {
            $scope.message = "";
        }, 10000);
    });

Answer 1

在您提供的代码中，您已启动了ajax调用并为Postman块提供了回调函数 - 也就是说，当ajax调用成功并返回数据时应该执行的操作。您还没有为AngularJS示例提供此功能。

$ http是一个基于承诺的包。您可以从General Usage下的Angular文档here中看到$ http应该使用.then（）处理程序调用，如下所示：

var settings = {
   //POST settings
}
$http(settings)
.then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
    console.log(response);
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
    console.log(response);
  });

只是转换请求并删除为我工作的标题上的缓存控件

最终代码

services.factory('documentService', ['$http', function($http){
return {
        getToken:function(grant_type,user,password){
            return $http({
                    method:"POST",
                    url:"http://197.156.93.110/Apiv1/token",
                    headers: {'Content-Type': 'application/x-www-form-urlencoded'}, 
                     transformRequest: function(obj) {
                        var str = [];
                        for(var p in obj)
                        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
                        return str.join("&");
                    },
                    data: {
                        "grant_type": "password",
                        "UserName": "user1",
                        "Password": "password"
                      }         
            });
        }

邮差相同的请求不在angularjs http请求中工作
