vue.js - Vue.js 使用 SendGrid v3 发送电子邮件：不允许访问

Question

我正在尝试使用 SendGrid v3 发送电子邮件...在开发模式下，当我从 localhost 发送消息并且我的 SendGrid 帐户已为我的生产域 www.mydomain.com 设置时，我收到一条错误消息：未授权..我能够了解...

Failed to load https://api.sendgrid.com/v3/mail/send: Response to preflight 
request doesn't pass access control check: The 'Access-Control-Allow-Origin' header 
has a value '://sendgrid.api-docs.io' that is not equal to the supplied origin. 
Origin '://localhost:8080' is therefore not allowed access. Have the server send 
the header with a valid value, or, if an opaque response serves your needs, 
set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

有什么方法可以在开发模式下使用 SendGrid 吗？还是我应该绕过发送邮件？

    if (process.env.NODE_ENV === 'production) {
      this.sendContactEmail()
    } else {
      console.log('CANNOT SEND MESSAGE IN DEVELOPMENT ENVIRONMENT')
    }
