proxyee's Introduction

HTTP 代理服务器

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。

HTTPS 支持

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1: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。

注2:Android 7以及以上,系统不再信任用户安装的证书,你需要root后,使用
cat ca.crt > $(openssl x509 -inform PEM -subject_hash_old -in ca.crt  | head -1).0
命令生成 d1488b25.0 文件,然后把文件移动到
/system/etc/security/cacerts/
并给与644权限

注3:在Android 7以及以上,即使你把证书添加进系统证书里,这个证书在chrome里也是不工作的。原因是chrome从2018年开始只信任有效期少于27个月的证书(https://www.entrustdatacard.com/blog/2018/february/chrome-requires-ct-after-april-2018)。所以你需要自行生成证书文件。

自定义根证书

  • 通过运行com.github.monkeywie.proxyee.crt.CertUtil类的main方法生成

  • 通过openssl

#key的生成,这样是生成RSA密钥,openssl格式,2048位强度。ca.key是密钥文件名。
openssl genrsa -out ca.key 2048

#key的转换,转换成netty支持私钥编码格式
openssl rsa -in ca.key -out ca_private.der -outform der
	
#crt的生成,通过-subj选项可以自定义证书的相关信息
openssl req -sha256 -new -x509 -days 365 -key ca.key -out ca.crt \
    -subj "/C=CN/ST=GD/L=SZ/O=lee/OU=study/CN=testRoot"

然后把ca.crt 和 ca_private.der 复制到项目的src/resources/中,或者实现HttpProxyCACertFactory接口来自定义加载根证书和私钥

二级代理

可设置二级代理服务器,支持http,socks4,socks5。

启动

//启动一个普通的http代理服务器,不解密https
new HttpProxyServer().start(9999);
//启动一个解密https的代理服务器,并且拦截百度首页,注入js和修改响应头
//当开启了https解密时,需要安装CA证书(`src/resources/ca.crt`)至受信任的根证书颁发机构。
HttpProxyServerConfig config =  new HttpProxyServerConfig();
config.setHandleSsl(true);
new HttpProxyServer()
    .serverConfig(config)
    .proxyInterceptInitializer(new HttpProxyInterceptInitializer() {
      @Override
      public void init(HttpProxyInterceptPipeline pipeline) {
        pipeline.addLast(new FullResponseIntercept() {

          @Override
          public boolean match(HttpRequest httpRequest, HttpResponse httpResponse, HttpProxyInterceptPipeline pipeline) {
            //在匹配到百度首页时插入js
            return HttpUtil.checkUrl(pipeline.getHttpRequest(), "^www.baidu.com$")
                && isHtml(httpRequest, httpResponse);
          }

          @Override
          public void handelResponse(HttpRequest httpRequest, FullHttpResponse httpResponse, HttpProxyInterceptPipeline pipeline) {
            //打印原始响应信息
            System.out.println(httpResponse.toString());
            System.out.println(httpResponse.content().toString(Charset.defaultCharset()));
            //修改响应头和响应体
            httpResponse.headers().set("handel", "edit head");
            /*int index = ByteUtil.findText(httpResponse.content(), "<head>");
            ByteUtil.insertText(httpResponse.content(), index, "<script>alert(1)</script>");*/
            httpResponse.content().writeBytes("<script>alert('hello proxyee')</script>".getBytes());
          }
        });
      }
    })
    .start(9999);
