URL方式:
URL url = null;
HttpURLConnection httpCon = null;
try {
url = new URL(orderListUrl + "?" + sData);
httpCon = (HttpURLConnection) url.openConnection();
httpCon.setUseCaches(false);
httpCon.setDoInput(true);
httpCon.setDoOutput(true);
httpCon.setInstanceFollowRedirects(false);
httpCon.setRequestMethod("GET");
BufferedReader reader = new BufferedReader(new InputStreamReader(httpCon.getInputStream(),"utf-8"));

String tmp = "";
while ((tmp = reader.readLine()) != null) {
strResponse += tmp + "\n";
}

httpClient:
public static String doPost(String url, NameValuePair[] data)
throws HttpException, IOException {
HttpClient client = new HttpClient();

client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET,
"utf-8");
PostMethod method = new PostMethod(url);

method.setRequestBody(data);
method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
new DefaultHttpMethodRetryHandler(3, false));
try {
client.executeMethod(method);

InputStream ins = method.getResponseBodyAsStream();
[color=red] BufferedReader br = new BufferedReader(new InputStreamReader(ins,
"utf-8"));[/color]
StringBuffer sbf = new StringBuffer();
String line = null;
while ((line = br.readLine()) != null) {
sbf.append(line);
}
br.close();
return sbf.toString();

} finally {
// Release the connection.
method.releaseConnection();
}
}
