如何在flutter中使用GetX和Get Connect解决ssl证书错误

Question

我正在尝试使用 Getx 服务。

这是我的 api 客户端类，我正在尝试使用 getx 从互联网获取数据

import 'package:flutter_application_shop/utilis/app_constance.dart';
import 'package:get/get.dart';

class ApiClient extends GetConnect implements GetxService {
  late String token;
  final String appBaseUrl;
  late Map<String, String> _mainHeaders;

  ApiClient({required this.appBaseUrl}) {
    baseUrl = appBaseUrl;
    timeout = const Duration(seconds: 30);
    token = AppConstance.TOKEN;

    _mainHeaders = {
      'Content-type': 'application/json; charset=UTF-8',
      'Authorization': 'Bearer $token',
    };
  }

  Future<Response> getData(String url) async {
    try {
      Response response = await get(url);
      return response;
    } catch (e) {
      return Response(statusCode: 1, statusText: e.toString());
    }
  }

  ///end
}

当我运行调试时，我收到此错误。

I/flutter ( 6967): HandshakeException: Handshake error in client (OS Error: 
I/flutter ( 6967):      CERTIFICATE_VERIFY_FAILED: unable to get local issuer certificate(handshake.cc:393))

我该如何解决这个问题？

Answer 1

这是因为请求来自不受信任的来源，为了绕过错误，请在扩展

allowAutoSignedCert = true;

的类中将

GetConnet

添加到您的请求中。

示例：

import 'package:flutter_application_shop/utilis/app_constance.dart';
import 'package:get/get.dart';

class ApiClient extends GetConnect implements GetxService {
  late String token;
  final String appBaseUrl;
  late Map<String, String> _mainHeaders;

  ApiClient({required this.appBaseUrl}) {
    baseUrl = appBaseUrl;
    timeout = const Duration(seconds: 30);
    token = AppConstance.TOKEN;
    allowAutoSignedCert = true; // the solution

    _mainHeaders = {
      'Content-type': 'application/json; charset=UTF-8',
      'Authorization': 'Bearer $token',
    };
  }

  Future<Response> getData(String url) async {
    try {
      Response response = await get(url);
      return response;
    } catch (e) {
      return Response(statusCode: 1, statusText: e.toString());
    }
  }
}

Answer 2

我遇到了同样的问题，

allowAutoSignedCert = true;

在ios上工作但在android上不起作用，并且扩展GetConnect的类的on init方法如下。

class BaseProvider extends GetConnect {
@override
void onInit() {
super.onInit();
httpClient.baseUrl = ApiConstants.baseUrl;
httpClient.timeout = ApiConstants.timeOutInSeconds;
allowAutoSignedCert = true;
 }
}

通过将

allowAutoSignedCert = true;

移动到 onInit() 方法的顶部，自动签名开始按预期工作：

class BaseProvider extends GetConnect {
@override
void onInit() {
allowAutoSignedCert = true; //Moved to top
super.onInit();
httpClient.baseUrl = ApiConstants.baseUrl;
httpClient.timeout = ApiConstants.timeOutInSeconds;
 }
}
