如何将ASP.NET 5(vNext)用户机密注入我自己的实用程序类？

Question

我已经用过:
user-secret set "AWSAccessKey" "my access key"和
user-secret set ""AWSSecretKey" "my secret key"

让我的钥匙进入秘密商店.

我有这个课程,我将用它来通过Amazon SES发送电子邮件,但我不知道如何将我的密钥插入其中.

public class MailHelper
{
    public void SendEmailSes(string senderAddress, string receiverAddress, string subject, string body)
    {
        using (var client = new AmazonSimpleEmailServiceClient(
            new BasicAWSCredentials("[AWSAccessKey]", "[AWSSecretKey]"),
            RegionEndpoint.USEast1))
        {
            var sendRequest = new SendEmailRequest
            {
                Source = senderAddress,
                Destination = new Destination { ToAddresses = new List<string> { receiverAddress } },
                Message = new Message
                {
                    Subject = new Content(subject),
                    Body = new Body { Text = new Content(body) }
                }
            };
            var response = client.SendEmail(sendRequest);
        }
    }
}

我在Startup.cs中放了什么才能在MailHelper类中获取这些键？需要添加什么到MailHelper类本身？

我已经看到了MVC控制器的一些示例,但我找不到任何尚未实现某些预期接口的自定义实用程序类.

适合您的设置的课程:

public class AwsSettings
{
    public string AccessKey { get; set; } = string.Empty;
    public string AccessSecret{ get; set; } = string.Empty;
}

如果您的设置在config.json中,您可以这样做:

{
  "AwsSettings": {
    "AccessKey": "yourkey",
    "AccessSecret": "yoursecret"
  }
}

在Startup中你需要这个:

services.Configure<AwsSettings>(Configuration.GetSection("AwsSettings"));

你的邮件程序类需要注入构造函数的设置

using Microsoft.Framework.OptionsModel;

public class MailHelper
{
    public MailHelper(IOptions<AwsSettings> awsOptionsAccessor)
    {
        awsSettings = awsOptionsAccessor.Options;
    }
    private AwsSettings awsSettings;

    ... your other methods

}

UserSecrets只是另一个配置源代码而不是config.json你可以把设置放在那里,但是你需要模拟结构,这样它就可以映射到你的类,所以你用冒号设置它们:

user-secret set "AwsSettings:AccessKey" "my access key" and
user-secret set "AwsSettings:AccessSecret" "my secret key"

这相当于我为config.json展示的结构

现在,设置将从用户机密中加载并注入邮件程序
