Identityserver4的自动映射器问题-MissingMethodException：找不到方法：'!! 0 AutoMapper.IMapper.MapSystem.Object' 问题/重现问题的步骤

编程问答 2022-08-15

问题描述

我使用的是IdentityServer 4的最新版本

问题/重现问题的步骤

  • 创建一个新的blazor webassembly应用
  • 我搭建了所有身份文件并对其进行了自定义
  • 和custom ApiAuthorizationDbContext用于blazor webassembly
  • 安装Automapper v10和AutoMapper.Extensions.Microsoft.DependencyIn v8.0.1

当我运行项目时，浏览器中出现500错误：

AuthenticationService.js:44 GET https://localhost:5001/connect/authorize?client_id=Web.Client&redirect_uri=https%3A%2F%2Flocalhost%3A5001%2Fauthentication%2Flogin-callback&response_type=code&scope=Web.ServerAPI%20openid%20profile&state=4b9b0120a48442a786b5bc8260c52f65&code_challenge=ViBkoIwumlfy_kg_y0bAh9uFsEByt2aKDOVUSREfARE&code_challenge_method=S256&prompt=none&response_mode=query 500

以及在自托管控制台中：
