UnicodeDecodeError: кодек ascii не может декодировать байт 0xff в позиции 0: порядковый не в диапазоне (128)

Question

У меня есть скрипт Python, который использует tinypng api для рекурсивного преобразования изображений и по какой-то причине он не работает, и я получаю :

UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0: ordinal not in range(128)

Что я делаю неправильно?

import os 
import base64 
from os.path import dirname 
from urllib2 import Request, urlopen 
from base64 import b64encode 

compress_png = True 
compress_jpg = True 
import_dir = '666\product' 
output_dir = '666\product' 
tiny_png_key = 'xxxxxx' 
tiny_png_url = 'https://api.tinypng.com/shrink' 

img_count = 0 
file_count = 0 
compress_count = 0 
existing_count = 0 


def compressImage(filepath, filedest, overwrite = True): 
    global compress_count 
    global existing_count 
    if not os.path.isfile(filedest) or overwrite: 
     status = '' 
     request = Request(tiny_png_url, open(filepath, "rb").read()) 
     auth = b64encode(bytes("api:" + tiny_png_key)).decode("ascii") 
     request.add_header("Authorization", "Basic %s" % auth) 
     response = urlopen(request) 

     if response.getcode() == 201: 
      status = "success"; 
      headers = response.info() 
      result = urlopen(headers["Location"]).read() 

      if not os.path.exists(os.path.dirname(filedest)): 
       os.makedirs(os.path.dirname(filedest)) 
      open(filedest, "wb").write(result) 
      compress_count += 1 
     else: 
      status = "failed" 
     print 'Compressing: %s\nFile: %s\nStatus: %s\n'%(filepath, img_count, status) 
    else: 
     existing_count += 1 


# loop througs files in import_dir recursively 
for subdir, dirs, files in os.walk(import_dir): 
    for file in files: 
     filepath = os.path.join(subdir, file) 
     fileName, fileExtension = os.path.splitext(file) 
     file_count += 1 
     if(fileExtension == '.png' and compress_png) or (fileExtension == '.jpg' and compress_jpg): 
      img_count += 1 
      filedest = filepath.replace(import_dir, output_dir) 
      compressImage(filepath, filedest) 


print '================' 
print 'Total Files: %s'%(file_count) 
print 'Total Images: %s'%(img_count) 
print 'Images Compressed: %s'%(compress_count) 
print 'Images Previously Compressed (Exist in output directory): %s'%(existing_count) 

Полная ошибка:

Используя пример на сайте и адаптации это для Python 2 так же, как вы, похоже, работали для меня:

from os.path import dirname 
from urllib2 import Request, urlopen 
from base64 import b64encode 

key = "xxxx_xxxx" 
input = "NLMK.png" 
output = "tiny-output.png" 

request = Request("https://api.tinypng.com/shrink", open(input, "rb").read()) 

auth = b64encode("api:" + key).decode("ascii") 
request.add_header("Authorization", "Basic %s" % auth) 

response = urlopen(request) 
if response.getcode() == 201: 
    # Compression was successful, retrieve output from Location header. 
    headers = response.info() 
    result = urlopen(headers["Location"]).read() 
    open(output, "wb").write(result) 
else: 
    # Something went wrong! You can parse the JSON body for details. 
    print("Compression failed")

Вы должны кодировать данные, но не имя пользователя Я хотел бы попробовать что-то вроде:

def compressImage(filepath, filedest, overwrite = True): 
    global compress_count 
    global existing_count 
    if not os.path.isfile(filedest) or overwrite: 
     status = '' 
     data = open(filepath, "rb").read() 
     data = base64.b64encode(data) 
     request = Request(tiny_png_url, data) 
     request.add_header("Content-type", "application/x-www-form-urlencoded; charset=UTF-8") 
     auth = "api:" + tiny_png_key 
     request.add_header("Authorization", "Basic %s" % auth) 
     response = urlopen(request)
