代理服务器后面的Volley [英] Volley behind a proxy server

问题描述

我是Volley Networking Library(Android版)的新手.我观察到Request函数将URL作为参数而不是服务器名称和端口.如果我提到服务器名称和端口，是否有任何方法可以使Volley请求通过我选择的代理服务器?

I am new to Volley Networking Library (of Android). I have observed that the Request function takes URL as the parameter instead of server name and port. Is there any way for making Volley request to go through a Proxy Server of my choice if I mention the server name and the port?

JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

我知道我们可以在构建URL时使用服务器和端口信息，但是还有其他方法可以确保请求通过我们提到的Proxy吗?

I know that we can make use of server and port info while building the URL but is there a way other than this to make sure that the requests go through a Proxy mentioned by us ?

例如:如何让HttpURLConnection使用代理?/a>这是确保HttpURLConnection使用代理的方法.我正在为Volley寻找类似的答案.

For example: How do I make HttpURLConnection use a proxy? Here is a method to ensure that HttpURLConnection uses a proxy. I am looking for similar answers for Volley.

推荐答案

Volley不提供任何直接设置代理的方法，但是有一种方法.

Volley doesn't offer any direct methods to set proxy but there is a way.

创建一个扩展HurlStack的自定义类，例如ProxiedHurlStack

Create a custom class extending HurlStack, say ProxiedHurlStack

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.URL;

import com.android.volley.toolbox.HurlStack;

public class ProxiedHurlStack extends HurlStack {

    @Override
    protected HttpURLConnection createConnection(URL url) throws IOException {

        // Start the connection by specifying a proxy server
        Proxy proxy = new Proxy(Proxy.Type.HTTP,
                InetSocketAddress.createUnresolved("192.168.1.11", 8118));//the proxy server(Can be your laptop ip or company proxy)
        HttpURLConnection returnThis = (HttpURLConnection) url
                .openConnection(proxy);

        return returnThis;
    }
}

现在使用以下方法初始化队列:

Now initialize your queue using:

mRequestQueue = Volley.newRequestQueue(context, new ProxiedHurlStack());
