java使用代理发送http请求，java代理发送请求, //一种方法是设

    //一种方法是设置全局的代理,在程序中如下设置：      System.setProperty("proxySet", "true");       System.setProperty("http.proxyHost", "192.168.7.33");       System.setProperty("http.proxyPort", "8080");      //还有一种就是在发送每次请求的时候设置代理：      URL url = new URL("http://www.open-open.com");       Proxy proxy = new Proxy(Proxy.Type.DIRECT.HTTP, new InetSocketAddress("192.168.7.33", 8080));       HttpURLConnection conn = (HttpURLConnection) url.openConnection(proxy);       InputStream in = conn.getInputStream();       BufferedReader bin = new BufferedReader(new InputStreamReader(in));       String s = null;       while((s=bin.readLine())!=null){           System.out.println(s);       }       bin.close();
