如何通过Android请求发送JSON对象?我想发送以下JSON文本{"Email":"aaa@tbbb.com","Password":"123456"}并读取响应。我知道怎么读JSON。问题是上面的JSON对象必须以变量名发送jason.我怎样才能在Android上做到这一点呢?创建请求对象、设置内容标题等步骤有哪些。

int TIMEOUT_MILLISEC = 10000; // = 10 secondsString postMessage="{}"; //HERE_YOUR_POST_STRING.HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpClient client = new DefaultHttpClient(httpParams);HttpPost request = new HttpPost(serverUrl);request.setEntity(new ByteArrayEntity(
postMessage.toString().getBytes("UTF8")));HttpResponse response = client.execute(request);

protected void sendJson(final String email, final String pwd) {
Thread t = new Thread() {
public void run() {
Looper.prepare(); //For Preparing Message Pool for the child Thread
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); //Timeout Limit
HttpResponse response;
JSONObject json = new JSONObject();
try {
HttpPost post = new HttpPost(URL);
json.put("email", email);
json.put("password", pwd);
StringEntity se = new StringEntity( json.toString());
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
post.setEntity(se);
response = client.execute(post);
/*Checking response */
if(response!=null){
InputStream in = response.getEntity().getContent(); //Get the data in the entity
}
} catch(Exception e) {
e.printStackTrace();
createDialog("Error", "Cannot Estabilish Connection");
}
Looper.loop(); //Loop in the message queue
}
};
t.start();
}

public void postData(String url,JSONObject obj) {
// Create a new HttpClient and Post Header
HttpParams myParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(myParams, 10000);
HttpConnectionParams.setSoTimeout(myParams, 10000);
HttpClient httpclient = new DefaultHttpClient(myParams );
String json=obj.toString();
try {
HttpPost httppost = new HttpPost(url.toString());
httppost.setHeader("Content-type", "application/json");
StringEntity se = new StringEntity(obj.toString());
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
httppost.setEntity(se);
HttpResponse response = httpclient.execute(httppost);
String temp = EntityUtils.toString(response.getEntity());
Log.i("tag", temp);
} catch (ClientProtocolException e) {
