本篇内容介绍了“java中HttpURLConnection的使用方法”的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!
代码只需要jdk就行,不需要依赖第三方jar包
package com.sean;
import sun.net.www.protocol.http.HttpURLConnection;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
public class HttpURLConnectionTest {
public static void main(String[] args) {
sendRequestWithHttpURLConnection();
}
private static void sendRequestWithHttpURLConnection() {
new Thread(new Runnable() {
@Override
public void run() {
HttpURLConnection connection = null;
BufferedReader reader = null;
try {
URL url = new URL("http://127.0.0.1:10000/service/sean?desc=description");
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setConnectTimeout(8000);
connection.setReadTimeout(8000);
//此时获取的是字节流
InputStream in = connection.getInputStream();
//对获取到的输入流进行读取
reader = new BufferedReader(new InputStreamReader(in)); //将字节流转化成字符流
StringBuilder response = new StringBuilder();
String line;
while ((line = reader.readLine())!= null) {
response.append(line);
}
System.out.println(response.toString());
} catch (Exception e ) {
e.printStackTrace();
} finally {
if (reader != null) {
try {
reader.close();
} catch (IOException e ) {
e.printStackTrace();
}
}
if ( connection!= null) {
connection.disconnect();
}
}
}
}).start();
}
}
