调研方向

首先按照“Extract text and layout information using the Form Recognizer REST API with Python” Quickstart 操作,并将其请求与失败的 get_url 函数以及报告中的 Form Recognizer v2.1 endpoint 进行比较。使用提供的 PDF 请求重现 BadArgument 响应,然后验证修正后的 Quickstart 能够在不出现错误的情况下返回操作 URL。

描述

The issue

The Quickstart for Form Recognizer REST API with Python is not functioning any more. It throws the following error:
POST analyze failed: {"error":{"code":"BadArgument","message":"Bad or unrecognizable request JSON or binary file."}}

Not sure if this has to do with the update to Form Recognizer REST API v3.0, but is not functioning for PDF anymore. It worked a few weeks ago.

My code
from requests import get, post, Request, Session

endpoint = r"https://westeurope.api.cognitive.microsoft.com"
key = "<my_personal_key"
source = r"<path to pdf>"

def get_url(filename, endpoint, apim_key):

    # v2.1
    post_url = endpoint + "/formrecognizer/v2.1/layout/analyze"

    headers = {
        # Request headers
        'Content-Type': 'application/pdf',
        'Ocp-Apim-Subscription-Key': apim_key,
    }

    with open(filename, "rb") as f:
        data_bytes = f.read()

    try:
        resp = post(post_url, data=data_bytes, headers=headers)
        if resp.status_code != 202:
            print("POST analyze failed:\n%s" % resp.text)
            return None
        print("POST analyze succeeded: %s" % resp.headers["operation-location"])
        get_url = resp.headers["operation-location"]
        return get_url
    except Exception as e:
        print("POST request failed:\n%s" % str(e))
        return None

resp_url = get_url(source, endpoint, key)
