问题
I am using Google Functions in order to generate PDFs.
我正在使用Google Functions来生成PDF文件。
I want to store the PDFs in a Google Bucket.
我想将这些PDF文件存储在Google Bucket中。
I know that I can store PDFs as a file using the following code:
我知道我可以使用以下代码将PDF文件存储为文件：
Write PDF to HTML
将PDF写入HTML
pdf = "
Hi!
"
HTML to PDF at local disk
将HTML转换为本地磁盘上的PDF
document = weasyprint.HTML(string=pdf, encoding='UTF-8')
document.write_pdf("Hello.pdf")
However, I want to store it in a Google Bucket, so I have tried the following code:
然而，我想将它存储在Google Bucket中，所以我尝试了以下代码：
Write PDF to HTML
将PDF写入HTML
pdf = "
Hi!

HTML to PDF in Google Bucket
将HTML转换为存储在Google Bucket中的PDF
document = weasyprint.HTML(string=pdf, encoding='UTF-8')
client = storage.Client()
bucket = client.get_bucket("monthly-customer-reports")
blob = bucket.blob("Hello.pdf")
with blob.open("w") as f:
f.write(str(document))
This stored a PDF in my Google Bucket but it was invalid.

你正在尝试将document对象的字符串表示写入文件，但这不是PDF二进制数据，你可以将其转换为二进制然后直接写入Google Cloud存储。
from google.cloud import storage
import weasyprint
pdf = "<html><title>Hello</title><body><p>Hi!</p></body></html>"
document = weasyprint.HTML(string=pdf, encoding='UTF-8')
pdf_bytes = document.write_pdf()
client = storage.Client()
bucket = client.get_bucket("monthly-customer-reports")
blob = bucket.blob("Hello.pdf")
blob.upload_from_string(pdf_bytes, content_type='application/pdf')
英文:
You are trying to write the string representation of the document object to the file, but this is not a PDF binary data, what you could do is convert to convert to binary then write it directly to Google Cloud storage.
from google.cloud import storage
import weasyprint
pdf = "<html><title>Hello</title><body><p>Hi!</p></body></html>"
document = weasyprint.HTML(string=pdf, encoding='UTF-8')
pdf_bytes = document.write_pdf()
client = storage.Client()
bucket = client.get_bucket("monthly-customer-reports")
blob = bucket.blob("Hello.pdf")
blob.upload_from_string(pdf_bytes, content_type='application/pdf')
