更新

如果这不是建议的存储应用程序配置的方法，请告诉我什么.

If this is not the recommended way to store app configs please let me know what is.

推荐答案

我不建议您从客户端读取配置文件.但是，如果您愿意，我建议您创建一个读取json文件并为客户端公开一些配置的服务.

I would not recommend reading the config file from your client side. But if you want to do I would suggest you create a service that read the json file and expo some configuration for client side.

您可以像这样从ASP.Net Core端进行配置

You can config from ASP.Net Core side like this

示例您在json中具有这样的配置

Example you have config like this in your json

"EmailSettings": { "MailServer": "", "MailPort": , "Email": "", "Password": "", "SenderName": "", "Sender": "", "SysAdminEmail": "" },

因此您需要使用config定义匹配的模型

So you need to define the matching model with config

public class EmailSettings { public string MailServer { get; set; } public int MailPort { get; set; } public string SenderName { get; set; } public string Sender { get; set; } public string Email { get; set; } public string Password { get; set; } public string SysAdminEmail { get; set; } }

然后在Startup.cs中注册

Then register in Startup.cs

services.Configure<EmailSettings>(configuration.GetSection("EmailSettings"));

因此您可以在服务中使用

So you can use in your service

private readonly IOptions<EmailSettings> _emailSetting; public EmailSender(IOptions<EmailSettings> emailSetting) { _emailSetting = emailSetting; } public string GetConfig(){ return _emailSetting.Value.SenderName; }
