在 Python 中使用 Google API 创建文档会引发错误

Question

在以下方法中，我尝试创建一个文档并将数据插入其中：

    from googleapiclient.discovery import build
    from google.oauth2 import service_account
    
    SERVICE_FILENAME = 'C:/Users/xyz/Test/service_account.json'  # set path to service account filename
    credentials = service_account.Credentials.from_service_account_file(SERVICE_FILENAME,
                                                                        scopes=['https://www.googleapis.com/auth/drive',
                                                                                'https://www.googleapis.com/auth/documents']
                                                                        )
    
    drive = build('drive', 'v3', credentials=credentials)
    docs = build('docs', 'v1', credentials=credentials)
    
    
    def fetch_folder_id():
        page_token = None
        response = drive.files().list(q="mimeType = 'application/vnd.google-apps.folder'",
                                      spaces='drive',
                                      fields='nextPageToken, files(id, name)',
                                      pageToken=page_token).execute()
        for file in response.get('files', []):
            # Process change
            print('Found file: %s (%s)' % (file.get('name'), file.get('id')))
            if file.get('name') == "Document_API":
                folder_id = file.get('id')
                return folder_id
                break
            page_token = response.get('nextPageToken', None)
            if page_token is None:
                break
    
    
    def create_Doc(folder_id):
        file_metadata = {
            'name': 'Test.docx',
            'parents': [folder_id]
        }
        file = drive.files().create(body=file_metadata,
                                    fields='id').execute()
        print('File ID: %s' % file.get('id'))
        file_id = file.get('id')
        return file_id
    
    
    def grant_permissions(file_id):
        try:
            permission = {
                "role": "writer",
                "type": "user",
                'emailAddress': 'xyz@gmail.com'
            }
            return drive.permissions().create(fileId=file_id, body=permission).execute()
        except Exception as e:
            print('An error occurred:', e)
        return None
        
    
    
    def insert_text(file_id):
        requests = [
            {
                'insertText': {
                    'location': {
                        'index': 1,
                    },
                    'text': 'Hellow'
                }
            },
            {
                'insertText': {
                    'location': {
                        'index': 7,
                    },
                    'text': 'Test'
                }
            },
    
        ]
    
        result = docs.documents().batchUpdate(documentId=file_id, body={'requests': requests}).execute()
        print(result)
    
    
    if __name__ == '__main__':
        folder_id = fetch_folder_id()
        file_id = create_Doc(folder_id)
        grant_permissions(file_id)
        insert_text(file_id)

方法：

1. 使用 Drive API 获取将保存 doc 文件的 folder_id
2. 使用 Drive API 将父级设为 folder_id 在该文件夹中创建文档
3. 使用 Drive API 授予文档所需的权限
4. 使用 Google Docs API 在文档中插入数据

错误： 文件正在创建中，权限也被授予，但无法在文件中插入数据。

Answer 1

在你的脚本中，下面的修改怎么样？

发件人：

file_metadata = {
    'name': 'Test.docx',
    'parents': [folder_id]
}

收件人：

file_metadata = {
    'name': 'Test', # or if you want to give the filename of 'Test.docx', please set it.
    'parents': [folder_id],
    'mimeType': 'application/vnd.google-apps.document'
}

• 从This operation is not supported for this document的错误信息来看，在这次修改中，函数create_Doc中的file_metadata被修改了。通过此修改，Google 文档被创建，并且该文档可以与 Docs API 一起使用。
  • 在您当前的脚本中，从docx 的扩展来看，创建的文件的mimeType 为application/vnd.openxmlformats-officedocument.wordprocessingml.document。这就是您的问题的原因。
