为 Microsoft Graph API 创建订阅：订阅验证请求失败

Question

我尝试为 Microsoft Graph 创建订阅 API。但是，我收到错误

Subscription validation request failed. Response must exactly match validationToken query parameter.

验证请求如下所示：

POST /?validationToken=Validation%3a+Testing+client+application+reachability+for+subscription+Request-Id%3a+c69b04df-f3d3-411c-8ceb-7f1ad8b7a927 HTTP/1.1

使用 FastApi，发送验证请求的 API 看起来像

from fastapi import FastAPI

app = FastAPI()

@app.post("/")
def read_call_record(validationToken):
    data = {"validationToken": validationToken}
    return data

返回的数据变量如下所示：

{'validationToken': 'Validation: Testing client application reachability for subscription Request-Id: c69b04df-f3d3-411c-8ceb-7f1ad8b7a927'}

有人可以帮忙

Answer 1

您的代码需要 Url 解码 validationToken 查询参数并将其 return 返回到 Graph。

来自 documentation，您的响应必须在 10 秒内发生并具有以下属性：

A status code of HTTP 200 OK.

A content type of text/plain.

A body that includes the URL decoded validation token. Simply reflect back the same string that was sent in the validationToken query parameter.

Important: If the client returns an encoded validation token, the validation will fail.

Answer 2

遮阳篷是我自己找的。这里的功能有效：

@app.post("/")
def read_call_record(validationToken):
    return Response(content=validationToken, media_type='text/plain')
