获取URL列表，设置代理请求URL，https的加密方式处理

2024-08-18 06:51:48   223人阅读

做了一个测试的一个小工具，需求如下：

1、有一批URL列表，需要知道哪个URL请求响应内容中包含http:关键字的。

2、url请求包括http和https 2种协议

3、要部署在linux服务器上，且linux服务器只能通过代理来连接外网

帖一下我的核心代码吧：

TrustAnyTrustManager 类中的方法，是我在网上找的，目地是解决SSL加密请求，针对https://协议的请求来处理的。具体是什么我也不懂

/*
             * System.setProperty("proxySet", "true");
             * System.setProperty("http.proxyHost", "192.168.11.254");
             * System.setProperty("http.proxyPort", "8080");
             */
这种设置代理的方式，不行的
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(
                    "192.168.11.254", 8080));
HttpURLConnection connection = (HttpURLConnection) realUrl
                            .openConnection(proxy);
