java.net发送值

获取url值 java.net.URL aURL = new java.net.URL(commURL);
打开链接 
urlConnection = (java.net.HttpURLConnection) aURL.openConnection();

//设置urlConnection属性

urlConnection.setRequestMethod(reqMethod);
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setUseCaches(false);
urlConnection.setRequestProperty("User-Agent", "MSIE");
urlConnection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded;charset=" + this.strEncode);
urlConnection
.setRequestProperty(
"Accept",
"image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-powerpoint, application/msword, application/vnd.ms-excel, */*");
urlConnection.setRequestProperty("Accept-Encoding", "gzip, deflate");
urlConnection.setReadTimeout(30000);
 //使用urlConnection进行连接

urlConnection.connect();

//获取连接的值
urlConnection.getOutputStream()
.write(msg.getBytes()/* ("UTF-8") */);

 

InputStreamReader in = new InputStreamReader(new BufferedInputStream(
urlConnection.getInputStream()), this.strEncode);
将回传的值放在sb字符串中
StringBuffer sb = new StringBuffer();
char buffer[] = new char[1024];
int len = 0;
while ((len = in.read(buffer)) > 0) {
sb.append(buffer, 0, len);
}
