WARN警告：Going to buffer response body of large or unknown size. Using getResponseBodyAsStream instead is recommended

使用Apache HttpClient发送请求，有大量WARN警告：Going to buffer response body of large or unknown size. Using getResponseBodyAsStream instead is recommended

原因：使用了 getResponseBodyAsString()的缘故

修改：getResponseBodyAsStream()，如下：

public Response get(String url, NameValuePair[] params) {
	Response response = new Response();

	GetMethod method = new GetMethod(url);
	method.setQueryString(params);
	method.getParams().setContentCharset(UTF8);

	try {
		response.setStatusCode(httpClient.executeMethod(method));
　
	  　// 使用getResponseBodyAsStream()代替getResponseBodyAsString使用流的方式来接收
		// response.setBody(method.getResponseBodyAsString());
		InputStream inputStream = method.getResponseBodyAsStream(); 

	BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
		StringBuffer stringBuffer = new StringBuffer();
		String str = "";
		while ((str = br.readLine()) != null) {
			stringBuffer.append(str);
		}
		response.setBody(stringBuffer.toString());
		return response;
	} catch (Exception e) {
		e.getStackTrace();
	} finally {
		method.releaseConnection();
	}
	return null;
}
