如何使用SendGrid编写用于发送电子邮件的云功能

Question

我正在尝试使用sendGrid发送电子邮件（在我的移动应用程序中）。所以我写了一个云函数并将其部署到firebase中。（使用它，访问https://angularfirebase.com/lessons/angular4-transactional-email-with-cloud-functions-and-sendgrid/）。

它被上传到firebase。但是，当我尝试发送post请求（使用postman{"to":"[email protected]","from":"[email protected]","subject":"test-email","content":"content"}）时，在firebase日志中显示一些错误

SendGridError: Response error

     headers: {} }

您需要处于“火焰”或“火焰”定价计划中。

事实上，免费的“Spark”计划“仅允许出站网络请求到Google拥有的服务”。请参阅https://firebase.google.com/pricing/（将鼠标悬停在“云功能”标题后面的问号上）

由于Sendgrid不是Google拥有的服务，因此您需要切换到“Flame”或“Blaze”计划。
