如何使用Postman

Question

使用Postman将图像添加到gmail api发送消息

我正在向gmail API发送发布请求 https://www.googleapis.com/upload/gmail/v1/users/userId/messages/send?upload=multipart，带有以下标题

Authorization Bearer [Your Token] Content-Type: multipart/related; boundary="foo_bar_baz" 并要求正文为

--foo_bar_baz
Content-Type: application/json; charset=UTF-8

{
}

--foo_bar_baz
Content-Type: message/rfc822
MIME-Version: 1.0
to: receiver@xxx.com
from: sender@xxx.com
subject: Testing API Automation

--foo_bar_baz
Content-Type: text/plain; charset="UTF-8"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit

This is the testing text

--foo_bar_baz

Content-Type: image/jpeg
MIME-Version: 1.0
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="Steps1.jpg"




--foo_bar_baz--

我不确定是否需要在请求正文中附加图像或将图像转换为rfc822格式。

目前，我得到以下回应 Bad content type. Please use multipart.
