以下是要求：
当我检查asynchttpclient的post方法时，我发现了以下方法： public RequestHandle post（String url，ResponseHandlerInterface responseHandler）{ return post（null，url，null，responseHandler）; }
// [-] HTTP POST
// [+] HTTP PUT
/**
* Perform a HTTP POST request with parameters.
*
* @param url the URL to send the request to.
* @param params additional POST parameters or files to send with the request.
* @param responseHandler the response handler instance that should handle the response.
* @return RequestHandle of future request process
*/
public RequestHandle post(String url, RequestParams params, ResponseHandlerInterface responseHandler) {
return post(null, url, params, responseHandler);
}
/**
* Perform a HTTP POST request and track the Android Context which initiated the request.
*
* @param context the Android Context which initiated the request.
* @param url the URL to send the request to.
* @param params additional POST parameters or files to send with the request.

*/

return post(context, url, paramsToEntity(params, responseHandler), null, responseHandler);
}

AsyncHttpClient client = new AsyncHttpClient();
RequestParams params = new RequestParams();
params.put("key", value);
client.post(context, URL_YOURURL,
params, new AsyncHttpResponseHandler() {
Progress pd = new Progress(context);
public void onStart() {
super.onStart();
pd.show();
}
@Override
public void onSuccess(int arg0,
Header[] arg1, byte[] arg2) {
try {
JSONObject json = new JSONObject(
new String(arg2));
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void onFailure(int arg0,
Header[] arg1, byte[] arg2,
Throwable arg3) {
}
public void onFinish() {
super.onFinish();
if(pd!=null){
pd.dismiss();
}
}
});
}
我想你是在问这个例子。
