使用 transformRequest 将 JSON 转换为 FormURL 编码数据

Question

我正在尝试将 JSON 数据转换为 formURL 编码数据，但仍然无法正常工作。

我的 HTTP post

$http.post(API_ENDPOINT.login, credentials, {
    transformRequest: transformRequestAsFormPost
 })

我的转换请求

'use strict';

define(['app-module'], function(app) {

$app.info('transformRequest initialized');

return app.factory('transformRequestAsFormPost', function() {

    function transformRequest(data, getHeaders) {
        var headers = getHeaders();
        headers["Content-Type"] = "application/x-www-form-urlencoded; charset=utf-8";
        return (serializeData(data));
    }

    function serializeData(data) {

        if (!angular.isObject(data)) {
            return ((data === null) ? "" : data.toString());
        }

        var buffer = [];

        for (var name in data) {
            if (!data.hasOwnProperty(name)) {
                continue;
            }

            var value = data[name];

            buffer.push(
                encodeURIComponent(name) +
                "=" +
                encodeURIComponent((value == null) ? "" : value)
            );

            console.log(buffer)

        }
        var source = buffer.join("&").replace(/%40/g, "@");
        return (source);
    }
    return (transformRequest);
});
});

我不知道我做错了什么。当我将任何 JSON 对象传递给它时，它 returns 一个字符串。

由于5da1256, transformRequest functions can no longer modify request headers. This behavior was unintended and undocumented, so the change should affect very few applications.¹

发送 POST 请求 Content-Type: application/x-www-form-urlencoded:

var config = {
  transformRequest: $httpParamSerializer,
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
  }
};

$http.post(API_ENDPOINT.login, credentials, config)
  .then(function(response) {
    console.log("SUCCESS");
}).catch(function(response) {
    console.log("ERROR");
    throw response;
});
