Python-docx 在 Google 云函数中

Question

有人试过在 google 云函数上使用 python-docx 吗？我才刚刚开始，无法使用下面的简单代码：

from docx import Document
document = Document('blank_doc.docx')
document.save('test.docx');

我认为这与存储桶有关，并在下面进行了尝试，但似乎无法正常工作。感谢帮助

from google.cloud import storage
from docx import Document   
client = storage.Client()
import io

def test(request):
    file_stream = io.BytesIO()

    BUCKET = 'out_bucket'
    document = Document('blank_doc.docx')
    bucket = client.get_bucket(BUCKET)
    document.save(file_stream)
    file_stream = file_stream.encode('utf-8')
    newblob = bucket.blob(file_stream)
    newblob.upload_from_file('document.docx')

在 Cloud Functions 上，您可以编写文档的唯一路径是 /tmp，如前所述，因此我将 Cloud Functions hello_world 重写为：

from docx import Document

def hello_world(request):

    document = Document()
    document.save('/tmp/test.docx');

    request_json = request.get_json()
    if request.args and 'message' in request.args:
        return request.args.get('message')
    elif request_json and 'message' in request_json:
        return request_json['message']
    else:
        return f'Hello World!'

并在 requirements.txt 文件中添加了下一行：
