支持HTTP、HTTPS、WebSocket,HTTPS采用动态签发SSL证书,可以拦截http、https的报文并进行处理。
例如：http(s)协议抓包,http(s)动态替换请求内容或响应内容等等。
需要导入项目中的CA证书(src/resources/ca.crt)至受信任的根证书颁发机构。
可以使用CertDownIntercept拦截器，开启网页下载证书功能，访问http://serverIP:serverPort即可进入。
注：安卓手机上安装证书若弹出键入凭据存储的密码，输入锁屏密码即可。
可设置二级代理服务器,支持http,socks4,socks5。

new HttpProxyServer()
// .proxyConfig(new ProxyConfig(ProxyType.SOCKS5, "127.0.0.1", 1085)) //使用socks5二级代理

@Override
public void init(HttpProxyInterceptPipeline pipeline) {
pipeline.addLast(new CertDownIntercept()); //处理证书下载
