【问题描述】：

我正在尝试编写程序来登录我的网站。但我在向网页发送帖子请求时遇到问题。

这是我的代码

script.js

function doLogin() {
    httpClient = new Windows.Web.Http.HttpClient();
    httpClient.defaultRequestHeaders.userAgent.parseAdd("Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)");
    var outputField = document.getElementById("test");

    var resourceAddress = new Windows.Foundation.Uri('http://localhost/test.php');
    var stringContent = new Windows.Web.Http.HttpStringContent("Data1=Value1&Data2=value");

    httpPromise = httpClient.postAsync(resourceAddress, stringContent).then(function (response) {
        return Helpers.displayTextResultAsync(response, outputField);
    });
    httpPromise.done(function () {

    }, Helpers.onError);
}

test.php

<?php
     print_r($_SERVER);
     print_r($_POST);
?>

响应请求

我在http://code.msdn.microsoft.com/windowsapps/HttpClient-sample-55700664 尝试了 Microsoft 示例代码参考，但它似乎不起作用。

【问题讨论】：

使用 WinJS 我无法获取 cookie，我的网站使用 asp.net，所以如果没有用户代理，它将返回错误。
有什么问题？ -_-
@Kiewic：未发送任何帖子数据
发布数据已发送，因为[CONTENT_LENGTH] => 54。但是 PHP 不知道如何解析它。

标签： javascript windows-8.1

【解决方案1】：

您必须将Content-Type 设置为application/x-www-form-urlencoded。即：

var stringContent = new Windows.Web.Http.HttpStringContent(
    "Data1=Value1&Data2=value",
    Windows.Storage.Streams.UnicodeEncoding.utf8,
    "application/x-www-form-urlencoded");
