如何在没有jQuery的情况下使用$ http发布urlencoded表单数据？

问题描述

我是AngularJS的新手，一开始，我想只使用AngularJS开发一个新的应用程序。

I am new to AngularJS, and for a start, I thought to develop a new application using only AngularJS.

我正在尝试对其进行AJAX调用服务器端，从我的Angular App使用 $ http 。

I am trying to make an AJAX call to the server side, using $http from my Angular App.

为了发送参数，我尝试了以下方法： / p>

For sending the parameters, I tried the following:

$http({
    method: "post",
    url: URL,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    data: $.param({username: $scope.userName, password: $scope.password})
}).success(function(result){
    console.log(result);
});

这是有效的，但它也在 $。param中使用jQuery 。为了消除对jQuery的依赖，我尝试了：

This is working, but it is using jQuery as well at $.param. For removing the dependency on jQuery, I tried:

data: {username: $scope.userName, password: $scope.password}

但这似乎失败了。然后我尝试 params ：

but this seemed to fail. Then I tried params:

params: {username: $scope.userName, password: $scope.password}

但这似乎也失败了。然后我尝试了 JSON.stringify ：

but this also seemed to fail. Then I tried JSON.stringify:

data: JSON.stringify({username: $scope.userName, password: $scope.password})

我找到了这些可能的答案我的追求，但没有成功。难道我做错了什么？我确信，AngularJS会提供这个功能，但是如何？

I found these possible answers to my quest, but was unsuccessful. Am I doing something wrong? I am sure, AngularJS would provide this functionality, but how?

推荐答案

我认为你需要做的是转换你的数据对象不是JSON字符串，而是url params。

I think you need to do is to transform your data from object not to JSON string, but to url params.

。

示例。

$http({
    method: 'POST',
    url: url,
    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: {username: $scope.userName, password: $scope.password}
}).then(function () {});

更新

添加新服务使用AngularJS V1.4，参见

UPDATE

To use new services added with AngularJS V1.4, see
