尝试使用代码生成器在 asp net core 3 中生成控制器时出错
Error trying to generate a controller in aspnet core 3 using codegenerator
我正在 asp net core 3.1.1 中开始一个新项目，使用 MYSQL数据库。我能够使用以下命令搭建模型
dotnet ef dbcontext scaffold "Server=localhost;User=root;Password=123456;Database=proyecto;TreatTinyAsBoolean=true;" Pomelo.EntityFrameworkCore.MySql -o Models
但是当我尝试使用 aspnet-codegenerator 生成任何控制器时，它会生成以下错误：不支持选项 'data server'。

数据库连接错误无法生成模型。另一方面，我尝试创建一个没有关联模型的控制器，但我没有遇到任何问题。这是我使用的命令。
dotnet aspnet-codegenerator controller -name ContactosController -dc LCoreContext -outDir Controllers -actions
如果您能提供给我任何帮助或提示，我将不胜感激。
错误消息 Option 'data server' not supported. 告诉您，您正在 LCoreConnection 连接字符串中使用名为 data server 的选项。
Pomelo 不支持此选项（有关支持的选项，请参阅 MySQL .NET Connection String Options）。
如果找不到设置此选项的位置，请执行解决方案范围内的搜索。

数据库连接错误无法生成模型。另一方面，我尝试创建一个没有关联模型的控制器，但我没有遇到任何问题。这是我使用的命令。
dotnet aspnet-codegenerator controller -name ContactosController -dc LCoreContext -outDir Controllers -actions
如果您能提供给我任何帮助或提示，我将不胜感激。
错误消息 Option 'data server' not supported. 告诉您，您正在 LCoreConnection 连接字符串中使用名为 data server 的选项。
Pomelo 不支持此选项（有关支持的选项，请参阅 MySQL .NET Connection String Options）。
如果找不到设置此选项的位置，请执行解决方案范围内的搜索。
