HttpURLConnection和httpclient添加代理IP和端口

/*代理设置*/
HttpClient httpclient = new DefaultHttpClient();
HttpHost proxy = new HttpHost(System.getProperty("http.proxyHost"), Integer.valueOf(System.getProperty("http.proxyPort")));
httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);


/*代理设置*/-
/*注意引入的类必须是-org.apache.http.HttpHost*/
Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress(System.getProperty("http.proxyHost"), Integer.valueOf(System.getProperty("http.proxyPort"))));
HttpURLConnection httpURLCOnnection= (HttpURLConnection) url.openConnection(proxy);

我的测试方法是放到外网服务器测试的，通过代理向微信发送信息，下面的方法涉及一些基础信息没有呈现，关键是几个关键语句，有这些关键语句即可。

此外，可以将一些信息添加到tomcat数据库的catalina.sh文件中

就可以不在程序中写死代理IP了

JAVA_OPTS="-server -Xms512m -Xmx512m -XX:PermSize=64M -XX:MaxPermSize=128m "
JAVA_OPTS="$JAVA_OPTS -Dhttp.proxySet=true "

JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=代理IP
JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyPort=代理端口

Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress(System.getProperty("http.proxyHost"),  Integer.valueOf(System.getProperty("http.proxyPort"))));         

我的程序是写死的，这样便于大家借鉴

public String test() throws IOException{

String url="https://api.weixin.qq.com/cgi-bin/menu/get?access_token="+access_token;
URL getUrl = new URL(url);
 // 根据拼凑的URL，打开连接，URL.openConnection函数会根据URL的类型，
        // 返回不同的URLConnection子类的对象，这里URL是一个http，因此实际返回的是HttpURLConnection
Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress("代理IP", 8080));                 //关键语句


        HttpURLConnection cOnnection= (HttpURLConnection) getUrl.openConnection(proxy);                                                                               //关键语句
        // 进行连接，但是实际上get request要在下一句的connection.getInputStream()函数中才会真正发到
        // 服务器
        connection.setConnectTimeout(25000);//关键语句
        connection.setReadTimeout(25000);//关键语句
        connection.connect();                                         //关键语句
        
        // 取得输入流，并使用Reader读取
        BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(),"utf-8"));
        String lines;
String jsOnString= "";
while ((lines = reader.readLine()) != null) {
jsOnString= jsonString + lines;
}


reader.close();
// 断开连接
connection.disconnect();
System.out.println("微信返回的json串" + jsonString);
ActionContext ctx = ActionContext.getContext();
HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);   
HttpServletResponse respOnse= (HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE);
jsOnString=jsonString.replace("<", "<");
jsOnString=jsonString.replace(">", ">");
request.setAttribute("str",jsonString);
request.setAttribute("str2", "系统没问题");

return "success";
}
