关于android：如何发送HTTP POST请求和接收响应？

How to send HTTP POST request and receive response?

我将创建可与CommuniGate Pro服务器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 Server S对话，并获取XIMSS.nonce节点值：

1

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>

例如，在ActionScript 3.0中，它看起来是这样的：

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 { ... };

在Java for Android 2.1中看起来如何？

正如Schnapple所说，您的问题似乎很广泛，难以理解和理解。

这是一些用于发送HTTP POST并从服务器获取响应的通用代码，尽管这可能会有所帮助。

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;
}
