有什么方法可以将chrome无头模式制作的PDF存储在RAM中？

Question

I'm trying to change an HTML to PDF using chrome headless mode and I'm looking for a way to store the response in RAM instead of storing it on the disk but I couldn't find a way to do that. Is there any possible way to do that?

Answer 1

To solve your problem, you can use tmpfs:

tmpfs can mount a disk partition in RAM.

Answer 2

Based on OP input - the goal is to get the content of the PDF into a program variable. There is no explicit problem limitation that will prevent using (temporary) file. The process will include the following steps * Generate the pdf file * Read the content of the file into (python) variable * Remove the temp file

Coded uses 'page.pdf' as temporary file, but this can be modified to place the temp file in a different location.

import os ;
url = "http://www.yahoo.com"
# Use chrome, or whatever name needed to launch chrome on your system
os.system("chromium-browser --headless --print-to-pdf=page.pdf " + url) ;
with open("page.pdf", mode='rb') as file:
    data = file.read()
# Remove the file, if needed
os.remove("page.pdf")
# Do something with data, e.g., print the size
print("file size=", len(data))
