flutter dio 抓包

1、第一种

写一个页面，输入ip地址和端口号，传给dio设置里

(_dio.httpClientAdapter as DefaultHttpClientAdapter).onHttpClientCreate = (HttpClient client) {
        client.idleTimeout = const Duration(seconds: 5);
        client.findProxy = (uri) {
          return "PROXY ${ip地址}:${端口号}";
        };
        //代理工具会提供一个抓包的自签名证书，会通不过证书校验，所以我们禁用证书校验
        client.badCertificateCallback = (X509Certificate cert, String host, int port) => true;
        return null;
      }

2、第二种

引入http_proxy: ^1.2.0第三方库，可获取代理信息

HttpProxy proxy = await HttpProxy.createHttpProxy();
    debugPrint("PROXY=${proxy.host}");
    if (proxy.host != null) {
      (_dio.httpClientAdapter as DefaultHttpClientAdapter).onHttpClientCreate = (HttpClient client) {
        client.idleTimeout = const Duration(seconds: 5);
        client.findProxy = (uri) {
          return "PROXY ${proxy.host}:${proxy.port}";
        };
        //代理工具会提供一个抓包的自签名证书，会通不过证书校验，所以我们禁用证书校验
        client.badCertificateCallback = (X509Certificate cert, String host, int port) => true;
        return null;
      };
    }
