我已经尝试适应the following script.我已经获得了后续的内容.
#!/usr/bin/python3
import re
import csv
import urllib.request, urllib.parse
class Spreadsheet(object):
def __init__(self, key):
super(Spreadsheet, self).__init__()
self.key = key
class Client(object):
def __init__(self, email, password):
super(Client, self).__init__()
self.email = email
self.password = password
def _get_auth_token(self, email, password, source, service):
url = "https://www.google.com/accounts/ClientLogin"
params = {
"Email": email, "Passwd": password,
"service": service,
"accountType": "HOSTED_OR_GOOGLE",
"source": source
}
req = urllib.request.Request(url, urllib.parse.urlencode(params))
return re.findall(r"Auth=(.*)", urllib.request.urlopen(req).read())[0]
def get_auth_token(self):
source = type(self).__name__
return self._get_auth_token(self.email, self.password, source, service="wise")
def download(self, spreadsheet, gid=0, format="csv"):
url_format = "https://spreadsheets.google.com/feeds/download/spreadsheets/Export?key=%s&exportFormat=%s&gid=%i"
headers = {
"Authorization": "GoogleLogin auth=" + self.get_auth_token(),
"GData-Version": "3.0"
}
req = urllib.request.Request(url_format % (spreadsheet.key, format, gid), headers=headers)
return urllib.request.urlopen(req)
if __name__ == "__main__":
email = "xxx" # (your email here)
password = "yyyy"
spreadsheet_id = "zzz" # (spreadsheet id here)
# Create client and spreadsheet objects
gs = Client(email, password)
ss = Spreadsheet(spreadsheet_id)
# Request a file-like object containing the spreadsheet's contents
print(gs.download(ss).read())
我的问题是我遇到以下错误.
Traceback (most recent call last):
File "/Users/test.py", line 54, in <module>
print(gs.download(ss).read())
File "/Users/test.py", line 38, in download
"Authorization": "GoogleLogin auth=" + self.get_auth_token(),
File "/Users/test.py", line 33, in get_auth_token
return self._get_auth_token(self.email, self.password, source, service="wise")
File "/Users/test.py", line 29, in _get_auth_token
return re.findall(r"Auth=(.*)", urllib.request.urlopen(req).read())[0]
File "/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/urllib/request.py", line 138, in urlopen
return opener.open(url, data, timeout)
File "/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/urllib/request.py", line 364, in open
req = meth(req)
File "/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/urllib/request.py", line 1052, in do_request_
raise TypeError("POST data should be bytes"
TypeError: POST data should be bytes or an iterable of bytes. It cannot be str.
麻烦来自方法_get_auth_token中的urllib.request.urlopen(req).有没有办法解决这个问题 ?
解决方法:
是的,在发布之前将数据编码为字节:
req = urllib.request.Request(url, urllib.parse.urlencode(params).encode('ASCII'))
我在这里假设您的数据仅是ASCII(电子邮件地址通常也是,大概您的密码也是).
