Microsoft graph api 在Microsoft Team Channel中以消息形式从本地系统发送文件/图像

如何使用Microsoft Graph API的发送消息在Microsoft Team频道中发送本地文件/图像

在创建发送团队频道的消息时，我跟随文档附上了一个图像。我正在尝试发送base64格式的图像。但是我犯了一个错误

{
    "error": {
        "code": "InternalServerError",
        "message": "Failed to process request.",
        "innerError": {
            "date": "2020-09-25T11:43:02",
            "request-id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
            "client-request-id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
        }
    }
}

似乎没有合适的API让您直接将本地文件作为消息发送

仅支持发送已在SharePoint中保存的文件。因此，发送本地文件有两个步骤：首先，将文件上载到SharePoint，然后创建聊天信息

---

1。将文件上载到SharePoint:

POST https://graph.microsoft.com/v1.0/teams/{id}/channels/{id}/messages
Content-type: application/json

{
    "body": {
        "contentType": "html",
        "content": "Here's the latest budget. <attachment id=\"153fa47d-18c9-4179-be08-9879815a9f90\"></attachment>"
    },
    "attachments": [
        {
            "id": "153fa47d-18c9-4179-be08-9879815a9f90",
            "contentType": "reference",
            "contentUrl": "https://m365x987948.sharepoint.com/sites/test/Shared%20Documents/General/test%20doc.docx",
            "name": "Budget.docx"
        }
    ]
}

小于4MB的文件：

PUT https://graph.microsoft.com/v1.0/drives/{{drive-id}}/items/root:/{{file-name}}:/content
Header:
"Authorization" : "Bearer <access-token>"
Body: binary (select binary option in body in postman)
Upload a file using select file option
file-name: is file name along with extension example: test.txt

GET: https://graph.microsoft.com/v1.0/drives/{{drive-id}}/items/root:/{{file-name}}:/createUploadSession
Header:
"Authorization" : "Bearer <access-token>"

PUThttps://graph.microsoft.com/v1.0/drives/{{drive id}}/items/root:/{{{file name}}:/content
标题：
“授权”：“持票人”

2.创建聊天信息：

POST https://graph.microsoft.com/v1.0/teams/{id}/channels/{id}/messages
Content-type: application/json

{
    "body": {
        "contentType": "html",
        "content": "Here's the latest budget. <attachment id=\"153fa47d-18c9-4179-be08-9879815a9f90\"></attachment>"
    },
    "attachments": [
        {
            "id": "153fa47d-18c9-4179-be08-9879815a9f90",
            "contentType": "reference",
            "contentUrl": "https://m365x987948.sharepoint.com/sites/test/Shared%20Documents/General/test%20doc.docx",
            "name": "Budget.docx"
        }
    ]
}

POSThttps://graph.microsoft.com/v1.0/teams/{id}/channels/{id}/messages
内容类型：application/json
{
“正文”：{
“内容类型”：“html”，
“内容”：“这是最新的预算。”
},
“附件”：[
{
“id”：“153fa47d-18c9-4179-be08-9879815a9f90”，
“内容类型”：“引用”，
“contentUrl”：”https://m365x987948.sharepoint.com/sites/test/Shared%20Documents/General/test%20doc.docx",
“名称”：“Budget.docx”
}
]
}
似乎没有合适的API可供您直接将本地文件作为消息发送

只支持发送已经在SharePoint中的文件。因此，有两个步骤可以发送本地文件：首先，将文件上载到SharePoint，然后创建chatMessage

您可以使用graph API发送文件附件。你能检查一下这个吗？@Nikitha msft谢谢。它适合我。你可以使用图形API发送文件附件。你能检查一下这个吗？@Nikitha msft谢谢。它对我有用。
