我正在尝试使用https://smba.trafficmanager.net/in/v3/conversations/以及以下附件格式将PDF文件作为附件主动发送给团队用户
"attachments": [
{
"contentType": "application/pdf",
"contentUrl": "http://www.africau.edu/images/default/sample.pdf",
"name": "sample.pdf",
"content": {
"uniqueId": "1150D938-8870-4044-9F2C-1213213123",
"fileType": "pdf"
}
}
]
每次我都能发送txt文件但不能发送pdf文件
{"error":{"code":"BadArgument","message":"Unknown attachment type"}}
除了application / pdf之外,还有其他contentType吗?
