Question

我将Laravel 7用于后端，将Nginx用于服务器，并将flutter用于应用程序。

我使用“让我们加密”和Certbot为服务器安装了SSL层。在使用SSL之前，一切都很好，它可以正常工作。但是安装SSL后，我在flutter上收到了此错误：

HandshakeExceiption：客户端中的握手错误（操作系统错误：TLSV1_ALERT_PROTOCOL_VERSION（tls_record.cc:587））

这是我的请求代码：

 import 'package:package_info/package_info.dart';
    import 'dart:io';
    import 'package:dio/dio.dart';
    import './home.dart';
    import './auth.dart';
    
    String token;
    
    class RootProvider {
      static Dio http = Dio();
      static final baseUrl = "https://my_domain.com/api";
      static String locale = '';
    
      static Future<void> setRequestHeaders() async {
        token = await AuthProvider.getToken();
        String _locale = await HomeProvider.getLocale();
        locale = _locale == 'en' ? 'tm' : _locale;
        PackageInfo packageInfo = await PackageInfo.fromPlatform();
        String platform = "";
    
        if (Platform.isAndroid) {
          platform = "android";
        } else if (Platform.isIOS) {
          platform = "ios";
        }
    
        var headers = {
          'Accept': 'application/json',
          'Content-Type': 'application/json',
          'Language': _locale == 'en' ? 'tm' : _locale,
          'Version': packageInfo?.version,
          'Platform': platform,
        };
        if (token != null) headers['Authorization'] = "Bearer $token";
        http.options.baseUrl = baseUrl;
        http.options.headers = headers;
      }
    
      static init() async {
        await setRequestHeaders();
    
        http.interceptors.add(
          InterceptorsWrapper(
            onRequest: (RequestOptions options) {
              print('Making request to ${options.method} ${options.uri}');
            },
            onResponse: (Response response) {
              // if response successful then return data
              if (response.data['success'] == true && response.data['success']) {
                return http.resolve(response);
              }
    
              return http.reject(response.data['message']);
            },
            onError: (DioError e) async {
              return http.reject(e);
            },
          ),
        );
      }
    }

这是我的Nginx conf：

server {
    listen 80;
    listen [::]:80;

    server_name my_domain.com;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name my_domain.com;
    root /var/www/my_domain/public;

        ssl_certificate /etc/letsencrypt/live/my_domain.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/my_domain.com/privkey.pem;

        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

        add_header X-Frame-Options "SAMEORIGIN";
        add_header X-XSS-Protection "1; mode=block";
        add_header X-Content-Type-Options "nosniff";

        index index.php index.html index.htm index.nginx-debian.html;

    charset utf-8;

    location / {
            try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
    }

    location ~ /\.ht {
            deny all;
    }

    location ~ /.well-known {
            allow all;
    }
}

注意：我试图通过Axios发送一个关于javascript的请求，并且得到了成功的响应。它适用于Axios和Javascript。它只对颤动不起作用。

请帮我发现问题。预先谢谢你
