好吧，我可以建议使用HttpClient以更高的抽象度来完成

DefaultHttpClient httpClient = null;

HttpParams my_httpParams = new BasicHttpParams();

httpClient = new DefaultHttpClient(my_httpParams);

然后发送

HttpPost httpPost = new HttpPost(stringUri);
httpPost.setHeader("Content-type", "application/x-www-form-urlencoded");
httpPost.setHeader("charset", "utf-8");

if (!TextUtils.isEmpty(someStringToSend)) {
    httpPost.setEntity(new StringEntity(someStringToSend, HTTP.UTF_8));
}

HttpResponse responsePOST = httpClient.execute(httpPost);
HttpEntity resEntity = responsePOST.getEntity();

if (resEntity != null) {
    response = EntityUtils.toString(resEntity, HTTP.UTF_8);
}

我还没有测试它，但应该可以工作。

调用

sendpostrest（字符串用户名，字符串传递）

方法和参数。您可以从UI线程调用此方法，请求将从其他线程发送（

AsyncTask

private void sendPostRequest（字符串givenUsername，字符串givenPassword）{
类SendPostReqAsyncTask扩展了AsyncTask{
