如何使用AngularJS中的一些数据进行$ http GET? [英] How to do a $http GET with some data in AngularJS?

问题描述

我想向我的后端发出Get请求，但是我想在发送响应对象之前验证一些用户凭据.

I want to make a Get request to my Backend, but I want to verify some user credentials before sending the response object.

这是我的代码:

$scope.getEverything = function (){
    $http.get('http://localhost:1234/things').success(function(data){
        $scope.things = data;
    });
};

我用以下语法尝试了相同的代码:

I've tried the same code with the following syntax:

$http.method('path).then
$http.method(config)

我只是不知道如何传递一些数据.尝试使用params:data作为配置对象，并打印输出:

And I just could not figure out how to pass in some data. Trying to use params:data as the config object with print out:

GET http://localhost:1234/[object％20Object] 404(不找到)

GET http://localhost:1234/[object%20Object] 404 (Not Found)

在控制台上.

AngularJS文档只字未提使用GET请求发送数据.我也尝试过一些Stack的答案，但是其中大多数已经过时了，将无法使用.

The AngularJS Docs don't say a word about sending data with GET requests. I've also tried some answers of Stack, but most of then are outdated and just won't work.

我可以使用GET请求发送数据，还是这只是我的应用程序的一个设计错误?

Can I send data with GET request or this is just one design error of my application?

推荐答案

您最有可能需要使用POST方法而不是GET方法.

You're most likely going to need to use a POST method instead of a GET method.

但是要使用GET方法:

But to do it with a GET method:

从 AngularJS将数据传递到$ http.get请求:

HTTP GET请求不能包含要发布到服务器的数据. 但是，您可以将查询字符串添加到请求中.

A HTTP GET request can't contain data to be posted to the server. However you can add a query string to the request.

angular.http为它的参数提供了一个选项.

angular.http provides an option for it params.

$http({
     url: user.details_path, 
     method: "GET",
     params: {user_id: user.id}  
});

并使用 AngularJS 进行POST:

$http.post('/someUrl', {msg:'hello word!'}).
  then(function(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });
