Java代码里利用Fiddler抓包调试设置
Fiddler启动时已经将自己注册为系统的默认代理服务器,应用程序在访问网络时会去获取系统的默认代理,如果需要捕获java访问网络时的数据,只需要在启动java程序时设置代理服务器为Fiddler即可
-DproxySet=true -DproxyHost=127.0.0.1 -DproxyPort=8888
-D 是java中设置系统变量的方式
下面的帖子很清楚的说明了设置Fiddler为http或者https的代理,包括如何设置https的证书

这是官网对这方面的描述:http://docs.oracle.com/javase/6/docs/technotes/guides/net/proxies.html

也可以通过程序进行设置(注意:设置代理一定要在程序请求之前)
System.setProperty("http.proxySet", "true"); System.setProperty("http.proxyHost", "127.0.0.1"); System.setProperty("http.proxyPort", "8888");
在Node Js中这样就行了
var http = require('http');var opt = {host:'127.0.0.1',port:'8888',method:'POST',path:'http://localhost/php/firstPro/test/weitest.php'}var body = '';var req = http.request(opt,function(res){console.log('Got Response'+ res.statusCode);res.on('data',function(d){ body += d; }).on('end',function(){console.log(res.headers)console.log(body);})});req.write("some data");req.end();
java http 程序设置代理
如果直接用java的 http API进行代理设置,如果是访问本地 ,则要在localhost后面加上. ,这应该是基于安全还是其他什么原因 ,如 http://localhost.:8080/app/index.jsp
public static String writeBytes(String url ,String data) throws Exception{ System.setProperty("http.proxySet", "true"); System.setProperty("http.proxyHost", "127.0.0.1"); System.setProperty("http.proxyPort", "8888"); HttpURLConnection httpURLConnection = (HttpURLConnection)new URL(url).openConnection(); // httpURLConnection.connect(); httpURLConnection.setRequestProperty("Accept-Charset", "utf-8"); httpURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); httpURLConnection.setDoInput(true); //true表示允许获得输入流,读取服务器响应的数据,该属性默认值为true httpURLConnection.setDoOutput(true); //true表示允许获得输出流,向远程服务器发送数据,该属性默认值为false httpURLConnection.setUseCaches(false); //禁止缓存 httpURLConnection.setReadTimeout(30000); //30秒读取超时 httpURLConnection.setConnectTimeout(30000); //30秒连接超时 httpURLConnection.setRequestMethod("POST"); httpURLConnection.setRequestProperty("Content-Length", data.length() + ""); OutputStream writer = httpURLConnection.getOutputStream(); writer.write(data.getBytes()); // writer.write( new byte[]{13,10,13,10} ); writer.flush(); InputStream in = httpURLConnection.getInputStream(); ByteArrayOutputStream buffer = new ByteArrayOutputStream(); byte[] buff = new byte[1024]; int len = -1; while((len= in.read(buff)) != -1){ buffer.write(buff, 0, len); } String result = buffer.toString("utf-8"); System.out.println(result); return result; }
用HttpClient进行代理
HttpClient httpclient = new HttpClient(connectionManager); HttpHost proxy = new HttpHost("127.0.0.1",8888); httpclient.getParams().setParameter(ConnRouteParams.DEFAULT_PROXY, proxy);
httpclient4 是这样设置,但是在commons-httpclient-3.1.jar 这个是无效的,这样就可以
httpclient.getHostConfiguration().setProxy("localhost", 8888);
