Sendgrid - 无法对 json 进行解组

Question

有人使用过Sendgrid 的v3/marketing/singlesends端点吗？此请求不适用于 POST 或 PUT。这个错误就像服务器错误有什么想法吗？

Client error: `POST https://api.sendgrid.com/v3/marketing/singlesends` resulted in a `400 BAD REQUEST` response:
{"errors":[{"field":"","message":"json could not be unmarshalled"}]}

Answer 1

当您提供错误的输入时会发生此错误。并且 api 已于 5 月 6 日更改
