java中两种发起POST请求，并接收返回的响应内容的方式  （转）

http://xyz168000.blog.163.com/blog/static/21032308201162293625569/

2、利用java自带的java.net.*包下提供的工具类

代码如下：

/**
* 利用URL发起POST请求，并接收返回信息
*
* @param url 请求URL
* @param message 请求参数
* @return 响应内容
*/
@Override
public String transport(String url, String message) {
StringBuffer sb = new StringBuffer();
try {
URL urls = new URL(url);
HttpURLConnection uc = (HttpURLConnection) urls.openConnection();
uc.setRequestMethod("POST");
uc.setRequestProperty("content-type",
"application/x-www-form-urlencoded");
uc.setRequestProperty("charset", "UTF-8");
uc.setDoOutput(true);
uc.setDoInput(true);
uc.setReadTimeout(10000);
uc.setConnectTimeout(10000);
OutputStream os = uc.getOutputStream();
DataOutputStream dos = new DataOutputStream(os);
dos.write(message.getBytes("utf-8"));
dos.flush();
os.close();
BufferedReader in = new BufferedReader(new InputStreamReader(uc
.getInputStream(), "utf-8"));
String readLine = "";
while ((readLine = in.readLine()) != null) {
sb.append(readLine);
}
in.close();
} catch (Exception e) {
log.error(e.getMessage(), e);
}
return sb.toString();
}
