上传文件并处理重定向 [PYTHON]

Question

I need to submit an image to the site https://zxing.org/w/decode.jspx , and read the result page: https://zxing.org/w/decode .

I tried this, but it does not work:

def decode_qrcode(path):
    s = requests.Session()

    url = "https://zxing.org/w/decode.jspx"
    files = {'file': open(path, 'rb')}
    s.post(url, files=files)
    return s.get("https://zxing.org/w/decode").text

I know that there are librairies to read QR code, but I did not find any that works for the kind of QR codes that I work with (they might have an error rate not supported).

Answer 1

You have to use the allow_redirects argument when making the POST request

import requests
def decode_qrcode(path):
    s = requests.Session()

    url = "https://zxing.org/w/decode.jspx"
    files = {'file': open(path, 'rb')}
    s.post(url, files=files, allow_redirects = True)
    return s.get("https://zxing.org/w/decode").text
