Python数据库中认知服务代码的重构

Question

以下代码提供了以下打印输出：

提供上述输出的代码是：

bcUrl = "https://raw.githubusercontent.com/Azure/azure-sdk-for-python/master/sdk/formrecognizer/azure-ai-formrecognizer/samples/sample_forms/business_cards/business-card-english.jpg"

poller = form_recognizer_client.begin_recognize_business_cards_from_url(bcUrl)
business_cards = poller.result()

for idx, business_card in enumerate(business_cards):
    print("--------Recognizing business card #{}--------".format(idx+1))
    contact_names = business_card.fields.get("ContactNames")
    if contact_names:
        for contact_name in contact_names.value:
            print("Contact First Name: {} has confidence: {}".format(
                contact_name.value["FirstName"].value, contact_name.value["FirstName"].confidence
            ))
            print("Contact Last Name: {} has confidence: {}".format(
                contact_name.value["LastName"].value, contact_name.value["LastName"].confidence
            ))

我正在尝试重构代码，以便将结果输出到dataframe，如下所示：

import pandas as pd
    
field_list = ["FirstName", "LastName"]
df = pd.DataFrame(columns=field_list)
bcUrl = "https://raw.githubusercontent.com/Azure/azure-sdk-for-python/master/sdk/formrecognizer/azure-ai formrecognizer/samples/sample_forms/business_cards/business-card-english.jpg"
    for blob in container.list_blobs():
      blob_url = container_url + "/" + blob.name
      poller = form_recognizer_client.begin_recognize_business_cards_from_url(bcUrl)
      business_cards = poller.result()
      print("Scanning " + blob.name + "...")
      
      for idx, business_card in enumerate(business_cards):
          single_df = pd.DataFrame(columns=field_list)
    
          for field in field_list:
            entry = business_card.fields.get(field)
            
            if entry:
              single_df[field] = [entry.value]
              
          single_df['FileName'] = blob.name
          df = df.append(single_df)
    
    df = df.reset_index(drop=True)
    df

但是，我的代码没有提供任何输出：

谁能看一看，让我知道为什么我没有得到任何输出？

当我试图连接blob存储时，我得到了相同类型的错误。我只是按照下面的语法连接blob存储，并且删除了.json和其他一些.fott文件，只有容器中有PDF。我运行相同的代码，没有任何问题，它运行良好。请遵循下面的参考，其中有详细的信息。
