怎么模拟GET请求

[eimhee]

虽然我用的是GET请求, httpurlconnection.setRequestMethod("GET");
但程序运行出来的是POST请求, 怎么改呢

package com.javaeye;

import java.net.HttpURLConnection;
import java.net.URL;

public class PostDemo {
static URL url = null;
static HttpURLConnection httpurlconnection = null;

public static void doPost() {
try {
url = new URL("http://www.XXXX.com/blogs/list");

httpurlconnection = (HttpURLConnection) url.openConnection();
httpurlconnection.setDoOutput(true);
httpurlconnection.setRequestMethod("GET");
// httpurlconnection.getOutputStream().write(getFileString().getBytes());

httpurlconnection.setRequestProperty("Cookie", "");
httpurlconnection.setRequestProperty("Connection", "Keep-Alive");
httpurlconnection.setRequestProperty("Referer", "http://extjs2.javaeye.com/");
httpurlconnection.setRequestProperty("Host", "www.javaeye.com");
httpurlconnection.getOutputStream().flush();
httpurlconnection.getOutputStream().close();
int code = httpurlconnection.getResponseCode();
System.out.println(httpurlconnection.getContentEncoding());
System.out.println(httpurlconnection.getContent());
//System.out.println(httpurlconnection.getOutputStream());
System.out.println("code " + code);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (httpurlconnection != null)
httpurlconnection.disconnect();
}

}

public static void main(String[] args) {
doPost();
}
}

关键是你运行了这一句：httpurlconnection.setDoOutput(true); 就把请求改变为post请求了，请求头的输出并不需要通过httpurlconnection的输出流，只要设置就行，httpurlconnection会在你需要得到服务器响应的时候使用socket连接web服务器，将请求头输出到web服务器，所以这样写就可以了：
public static void doPost() {
try {
url = new URL("http://www.XXXX.com/blogs/list");

httpurlconnection = (HttpURLConnection) url.openConnection();
//httpurlconnection.setDoOutput(true); 这一句不要
//httpurlconnection.setRequestMethod("GET"); 这一句不要，缺省就是get
// httpurlconnection.getOutputStream().write(getFileString().getBytes());

httpurlconnection.setRequestProperty("Cookie", "");
httpurlconnection.setRequestProperty("Connection", "Keep-Alive");
httpurlconnection.setRequestProperty("Referer", "http://extjs2.javaeye.com/");
httpurlconnection.setRequestProperty("Host", "www.javaeye.com");
//httpurlconnection.getOutputStream().flush(); 这一句不要
//httpurlconnection.getOutputStream().close(); 这一句不要
int code = httpurlconnection.getResponseCode();
System.out.println(httpurlconnection.getContentEncoding());
System.out.println(httpurlconnection.getContent());
//System.out.println(httpurlconnection.getOutputStream());
System.out.println("code " + code);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (httpurlconnection != null)
httpurlconnection.disconnect();
}

楼上高手, 弄明白是怎么回事了

[llp20_2000]

厉害,一直觉得有这个问题,现在明白了.SetRequestMethod("GET")为啥不生效.

new_bird_0001是高手，今天弄java的http也出现跟楼主一样的问题，呵呵。
