Question

首先，我收到状态代码200.在php脚本中，我只是将代码邮寄给我发送到服务器（我尝试调试时）。使用var_dump $ _POST或$ _REQUEST我收到一封空白电子邮件。如果我在$ _SERVER上运行foreach，我会得到一些数据，如HTTP_USER_AGENT：Apache-HttpClient / UNAVAILABLE（java 1.4）和CONTENT_LENGTH：9

我不明白为什么没有帖子数据？我是机器人新手，我实际上是在学习。

HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(dest_url);
    //httppost.setHeader("Accept", "application/json");
    //httppost.setHeader("Content-type", "application/json");

//JSONObject json = new JSONObject();

        // Add your data
        //json.put("action", "login");
        //json.put("username", "kermit");
        //json.put("password", "123456");

    ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    //nameValuePairs.add(new BasicNameValuePair("myjson", json.toString()));
    nameValuePairs.add(new BasicNameValuePair("plswork", "hi"));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));

    //StringEntity str_json = new StringEntity(json.toString());

    //httppost.setEntity(str_json);
    HttpResponse response;

    response = httpclient.execute(httppost);

我的manifestxml包含以下行;

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

这些是我的进口商品;

很可能与你的

有关

httppost.setHeader("Content-type", "application/json");

application/json不是HTTP POST表单提交的正常内容类型。考虑到你并没有真正发送json而是发送标准POST实体（nameString = valueString），请尝试将其更改为

httppost.setHeader("Content-Type", "application/x-www-form-urlencoded")

并查看这是否会对您的问题进行排序。或者更好的是，完全删除它。

我在我的应用程序中使用此代码 - 它完全正常：

HttpPost httppost = new HttpPost(SERVER_URL);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("REQUEST", req));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
HttpResponse response = httpclient.execute(httppost);

在这种情况下的回复是text/xml - 但这不重要。
