python中cookie中文乱码怎么解决
python中直接设置与获取cookie时,会出现编码错误。
(1)在设置cookie时没有考虑编码问题,例如书写的格式为:
response.set_cookie("favorite_color",request.GET["favorite_color"])

当cookie中含有中文时,可能会出现下面的错误:
Traceback (most recent call last):File "D:program filespython37libsocketserver.py", line 650, in process_request_thread
self.finish_request(request, client_address)
File "D:program filespython37libsocketserver.py", line 360, in finish_request
self.RequestHandlerClass(request, client_address, self)
File "D:program filespython37libsocketserver.py", line 720, in __init__
self.handle()
File "D:pythonworkspacemysitevenvlibsite-packagesdjangocoreserversasehttp.py", line 154, in handle
handler.run(self.server.get_app())
File "D:program filespython37libwsgirefhandlers.py", line 144, in run
self.close()
File "D:program filespython37libwsgirefsimple_server.py", line 35, in close
self.status.split(' ',1)[0], self.bytes_sent
AttributeError: 'NoneType' object has no attribute 'split'
(2)我们可能会想到在设置cookie值的时候通过encode('utf-8')函数进行转码,于是进一步改进的代码为:
response.set_cookie("favorite_color",request.GET["favorite_color"].encode('utf-8'))
这是网页就能顺利获取到的cookie中包含的中文字符了。
但是又出现了另外一个问题:后台获取刚刚存放在cookie中的值时,显示的内容不是原本的字符,而是转码后的十六进制字符,类似于下面这种:
Your favorite color is b'xe8x93x9dxe7xbbxbfxe8x89xb2'
(3)解决方案为:
存储cookie的方法:
favorite_color=request.GET.get('favorite_color')color=favorite_color.encode('utf-8').decode('latin-1')
response.set_cookie("favorite_color",color)
获取cookie的方法:
return HttpResponse("Your favorite color is %s" % request.COOKIES["favorite_color"].encode('latin-1').decode('utf-8'))
