如何在颤振中绕过 SSL 证书验证? [英] How to Bypass SSL Certificate Verification in flutter?

问题描述

如何在flutter中绕过SSL证书验证?错误:握手异常:客户端中的握手错误(操作系统错误:CERTIFICATE_VERIFY_FAILED:自签名证书(handshake.cc:345)

解决方案

您需要配置您的 HttpService 以使用自签名 SSL 本地服务器.像这样:

<预><代码>导入飞镖:io"；导入飞镖:转换"；类 HttpService {未来<动态>sendRequestToServer(dynamic model, String reqType, bool isTokenHeader, String token) async {HttpClient 客户端 = 新的 HttpClient();client.badCertificateCallback =((X509Certificate cert, String host, int port) => true);HttpClientRequest request = await client.postUrl(Uri.parse("https://${serverConstants.serverUrl}$reqType"));request.headers.set('Content-Type', 'application/json');如果(isTokenHeader){request.headers.set('Authorization', 'Bearer $token');}request.add(utf8.encode(jsonEncode(model)));HttpClientResponse 结果 = 等待 request.close();如果(结果.状态代码 == 200){返回 jsonDecode(await result.transform(utf8.decoder).加入());} 别的 {返回空；}}}

解决方案

You need to configure your HttpService to work with Self-Signed SSL local servers. Like this:

import 'dart:io';
import 'dart:convert';
class HttpService {
  Future<dynamic> sendRequestToServer(dynamic model, String                         reqType, bool isTokenHeader, String token) async {
      HttpClient client = new HttpClient();
      client.badCertificateCallback =((X509Certificate cert, String  host, int port) => true);
      HttpClientRequest request = await         client.postUrl(Uri.parse("https://${serverConstants.serverUrl}$reqType"));
      request.headers.set('Content-Type', 'application/json');
      if(isTokenHeader){
         request.headers.set('Authorization', 'Bearer $token');
      }
     request.add(utf8.encode(jsonEncode(model)));
     HttpClientResponse result = await request.close();
     if(result.statusCode == 200) {
        return jsonDecode(await result.transform(utf8.decoder)
        .join());
     } else {
        return null;
     }
   }
}
