发出请求时 Azure 表单识别器错误属性错误

Question

我正在尝试按照此文档进行表单识别 API，特别是识别收据的示例：

https://docs.microsoft.com/en-us/azure/cognitive-services/form-recognizer/quickstarts/client-library?pivots=programming-language-python&tabs=windows

我正在尝试以下代码：

import sys
import logging
from azure.ai.formrecognizer import FormRecognizerClient
from azure.core.credentials import AzureKeyCredential
import os
import azure.ai.formrecognizer

endpoint = r"https://form-recognizer-XXXXX-test.cognitiveservices.azure.com/"
form_recognizer_client = FormRecognizerClient(endpoint=endpoint, credential="XXXXXXXXX")
receiptUrl = "https://raw.githubusercontent.com/Azure/azure-sdk-for-python/master/sdk/formrecognizer/azure-ai-formrecognizer/tests/sample_forms/receipt/contoso-receipt.png"

poller = form_recognizer_client.begin_recognize_receipts_from_url(receiptUrl)
receipts = poller.result()

并收到此错误：

    request.http_request.headers[self._name] = self._credential.key

AttributeError: 'str' object has no attribute 'key'

我看到的不同之处在于，在示例中，端点和密钥被称为 class:

的属性

form_recognizer_client = FormRecognizerClient(endpoint=self.endpoint, credential=AzureKeyCredential(self.key))

但我看不出 "self." 是从哪里来的，为什么这个值不是字符串。

我同意快速入门中该密钥的来源有点不清楚。在该示例中，API 键被设置为 class 变量（self 的来源），但您无需执行此操作即可使您的代码正常工作。

为了成功进行身份验证，字符串 API 密钥 "XXXXXXXXX" 必须包装在凭据 class AzureKeyCredential 中。我已经在下面更新了您的代码来执行此操作，请告诉我它是否适合您：

import sys
import logging
from azure.ai.formrecognizer import FormRecognizerClient
from azure.core.credentials import AzureKeyCredential
import os
import azure.ai.formrecognizer

endpoint = r"https://form-recognizer-XXXXX-test.cognitiveservices.azure.com/"
form_recognizer_client = FormRecognizerClient(endpoint=endpoint, 
    credential=AzureKeyCredential("XXXXXXXXX"))
receiptUrl = "https://raw.githubusercontent.com/Azure/azure-sdk-for- 
    python/master/sdk/formrecognizer/azure-ai- 
    formrecognizer/tests/sample_forms/receipt/contoso-receipt.png"

poller = form_recognizer_client.begin_recognize_receipts_from_url(receiptUrl)
receipts = poller.result()
