HttpURLConnection向Servlet写入流方法实例代码教程。

public static void main(String[] args) throws IOException {
String r = AnalysisXML.getXml(); //要传入的xml字符串
String path =”http://localhost:8080/axis/services/bxserver”;
java.net.URL url = new java.net.URL(path);
// 打开连接
HttpURLConnection connection = (HttpURLConnection) url
.openConnection();
// 设置是否向connection输出，因为这个是post请求，参数要放在
// http正文内，因此需要设为true
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod(“POST”);
// Post 请求不能使用缓存
connection.setUseCaches(false);
connection.setInstanceFollowRedirects(true);
connection.setRequestProperty(“Content-Type”,
“text/xml”);
connection.connect();
DataOutputStream out = new DataOutputStream(connection
.getOutputStream());
out.writeBytes(r);
out.flush();
out.close();
BufferedReader reader = new BufferedReader(new InputStreamReader(
connection.getInputStream()));
String line;
System.out.println(“=============================”);
System.out.println(“Contents of post request”);
System.out.println(“=============================”);
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
System.out.println(“=============================”);
System.out.println(“Contents of post request ends”);
System.out.println(“=============================”);
reader.close();
connection.disconnect();
}
Servlet中获取流信息：
[java]view plaincopyprint?在CODE上查看代码片派生到我的代码片
String resultXml = “”;
boolean resultStr = true;
String XMLData = null;
StringBuffer tempStringBuffer = new StringBuffer();
String tempString = null;
BufferedReader reader = request.getReader();
while ((tempString = reader.readLine()) != null){
tempStringBuffer.append(tempString);
}
XMLData = tempStringBuffer.toString();
