TypeError：POST數據應該是字節或可迭代的字節。它不能是類型str

Question

我的代碼。

#!/usr/bin/env python 
#coding: utf-8 
userid="NicoNicoCreate@gmail.com" 
passwd="********" 
import sys, re, cgi, urllib, urllib.request, urllib.error, http.cookiejar, xml.dom.minidom, time, urllib.parse 
import simplejson as json 

def getToken(): 
    html = urllib.request.urlopen("http://www.nicovideo.jp/my/mylist").read() 
    for line in html.splitlines(): 
     mo = re.match(r'^\s*NicoAPI\.token = "(?P<token>[\d\w-]+)";\s*',line) 
     if mo: 
      token = mo.group('token') 
      break 
    assert token 
    return token 

def mylist_create(name): 
    cmdurl = "http://www.nicovideo.jp/api/mylistgroup/add" 
    q = {} 
    q['name'] = name.encode("utf-8") 
    q['description'] = "" 
    q['public'] = 0 
    q['default_sort'] = 0 
    q['icon_id'] = 0 
    q['token'] = token 
    cmdurl += "?" + urllib.parse.urlencode(q).encode("utf-8") 
    j = json.load(urllib.request.urlopen(cmdurl), encoding='utf-8') 
    return j['id'] 

def addvideo_tomylist(mid,smids): 
    for smid in smids: 
     cmdurl = "http://www.nicovideo.jp/api/mylist/add" 
     q = {} 
     q['group_id'] = mid 
     q['item_type'] = 0 
     q['item_id'] = smid 
     q['description'] = u"" 
     q['token'] = token 
     cmdurl += "?" + urllib.parse.urlencode(q).encode("utf-8") 
     j = json.load(urllib.request.urlopen(cmdurl), encoding='utf-8') 
     time.sleep(0.5) 

#Login 
opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(http.cookiejar.CookieJar())) 
urllib.request.install_opener(opener) 
urllib.request.urlopen("https://secure.nicovideo.jp/secure/login", 
       urllib.parse.urlencode({"mail":userid, "password":passwd})).encode("utf-8") 
#GetToken 
token = getToken() 
#MakeMylist&AddMylist 
mid = mylist_create(u"Testlist") 
addvideo_tomylist(mid, ["sm9","sm1097445", "sm1715919" ]) 

MyError。

我試過編碼，但它沒有幫助。 我是日本學生。 我的知識無法解決。 我知道這個類似的問題，TypeError：POST數據應該是字節或可迭代的字節。它不可能是，但是對於答案來說太新了很多幫助。

您括號是放錯了地方，所以你實際上並沒有編碼：

.urlencode({"mail":userid, "password":passwd}).encode("utf-8")) # <- move inside
