Android 如何发送HTTP POST请求并接收响应？

我将创建与CommuniGate Pro server配合使用的移动应用程序

例如，我需要进行以下Android客户端

C

-CGP服务器

S

对话，并获取

XIMSS.nonce

节点值：

C:GET /ximsslogin/ HTTP/1.1
  Host: myserver.com
  Content-Type: text/xml
  Content-Length: 42

  <XIMSS><listFeatures id="list" /><XIMSS>

S:HTTP/1.1 200 OK
  Content-Length: 231
  Connection: keep-alive
  Content-Type: text/xml;charset=utf-8
  Server: CommuniGatePro/5.3

  <XIMSS><nonce>2C3E575E5498CE63574D40F18D00C873</nonce><language>german</language><response id="s"/></XIMSS>

Android 2.1在Java中会是什么样子？

正如Schnapple所说，您的问题似乎非常广泛，阅读和理解起来很混乱

下面是一些发送HTTP POST并从服务器获得响应的通用代码，尽管这可能会有所帮助

我相信为了得到有意义的帮助，您需要详细说明。当我使用此方法时，我从服务器得到的响应是“未提供图像”。如何解决这个问题？

var loader:Loader = new Loader();
loader.addEventListener(Event.COMPLETE, completeHandler);
var urlRequest:URLRequest = new URLRequest(...);
urlRequest.method = ...;
urlRequest.data = ...;
loader.load(urlRequest);

private function completeHandler(...):void { ... };

public String postPage(String url, File data, boolean returnAddr) {

    ret = null;

    httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2109);

    httpPost = new HttpPost(url);
    response = null;

    FileEntity tmp = null;       

    tmp = new FileEntity(data,"UTF-8");

    httpPost.setEntity(tmp);

    try {
        response = httpClient.execute(httpPost,localContext);
    } catch (ClientProtocolException e) {
        System.out.println("HTTPHelp : ClientProtocolException : "+e);
    } catch (IOException e) {
        System.out.println("HTTPHelp : IOException : "+e);
    } 
            ret = response.getStatusLine().toString();

            return ret;
}
