我有一个Python脚本,它使用tinypng api递归地转换图像,由于某些原因它无法工作,我得到:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0: ordinal not in range(128)
我做错什么了?在
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)
完全错误:

你必须对数据进行编码,而不是用户名 我会尝试类似的方法:
使用网站上的示例并按照您所做的方式将其调整为Python 2,似乎对我很有用:
