为 Jersey 客户端配置代理

2022-01-21 00:00:00 proxy java jersey

我想为我的 Jersey 客户端配置一个代理服务器.
我不想为整个应用程序配置代理(使用 JVM 参数，例如 http.proxyHost)，我宁愿不使用 Apache 客户端.
我读到 这里 有一个选项通过提供 HttpUrlConnection 来做到这一点通过 HttpUrlConnectionFactory，但我找不到任何代码示例.
有谁知道我该怎么做?
谢谢！

I would like to configure a proxy server to my Jersey client.
I don't want to configure the proxy to the whole application (using JVM arguments such as http.proxyHost), and Id'e rather not use Apache client.
I read here that there is an option to do it by providing HttpUrlConnection via HttpUrlConnectionFactory, but I couldn't find any code example.
Does anyone know how can I do it?
Thanks!

在Luca的帮助下，我搞定了:

With the help of Luca, I got it done:

  1. 实现HttpURLConnectionFactory，并覆盖getHttpURLConnection方法，我的实现是(感谢Luca):

  1. Implement HttpURLConnectionFactory, and override the method getHttpURLConnection, my implementation is (thanks to Luca): 

Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("127.0.0.1", 3128));
return new HttpURLConnection(url, proxy);

  • 在实例化 Jersey 客户端之前，创建一个新的 URLConnectionClientHandler，并在其构造函数中提供您的 HttpURLConnectionFactory.然后创建一个新的 Client，并在 Client 构造函数中提供您的 ClientHandler.我的代码:

  • Before instantiating the Jersey Client, create a new URLConnectionClientHandler, and provide your HttpURLConnectionFactory in its constructor. Then create a new Client, and provide your ClientHandler in the Client constructor. My code: 

    URLConnectionClientHandler urlConnectionClientHandler = new URLConnectionClientHandler(new MyHttpURLConnectionFactory());
_client = new Client(urlConnectionClientHandler);

    • 希望对您有所帮助.
