参考：
在项目的 Properties\launchSettings.json中可以配置多个环境
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:49716/",
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"launchUrl": "api/values",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"ApiCenter": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "api/values",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"applicationUrl": "http://localhost:5001/"
},
"ApiCenter-Test": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "api/values",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Staging"
},
"applicationUrl": "http://localhost:5002/"
},
"ApiCenter-Production": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "api/values",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Production"
},
"applicationUrl": "http://localhost:5003/"
}
}
}
在VS调试的时候可以选择使用哪个
对应的appsetting.json
这样就可以在不同的环境使用不同的配置
设置环境
Windows
cmd中执行
set ASPNETCORE_ENVIRONMENT=Development
这个只对当前cmd窗口有效，关闭后就失效了，要永久修改的话可以设置环境变量
Linux
使用export 或者永久修改/etc/profile
接下来在发布目录执行就会使用配置的环境了
当然如果在源码目录执行的话只会使用第一个配置
把上面两个注释再执行
通过命令参数配置
如原来的数据库配置地址如下
"ConnectionStrings": {
"DefaultConnection": "Server=10.202.202.245;Database=test;uid=sa;pwd=password"
}
可以使用命令更改
dotnet ApiCenter.dll /ConnectionStrings:DefaultConnection=Server=10.15.4.155;Database=postgres;uid=root;pwd=password
