我下載了一個google-spreadsheet作爲python中的對象。使用openpyxl從內存中讀取文件
如何使用openpyxl使用工作簿而不先將其保存到磁盤?
我知道xlrd可以做到這一點:
book = xlrd.open_workbook(file_contents=downloaded_spreadsheet.read())
與「downloaded_spreadsheet」是我下載XLSX文件爲對象。
而不是xlrd,我想使用openpyxl,因爲更好的xlsx-support(我讀過)。
我使用這個迄今爲止...
#!/usr/bin/python
import openpyxl
import xlrd
# which to use..?
import re, urllib, urllib2
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 = urllib2.Request(url, urllib.urlencode(params))
return re.findall(r"Auth=(.*)", urllib2.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="xls"):
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 = urllib2.Request(url_format % (spreadsheet.key, format, gid), headers=headers)
return urllib2.urlopen(req)
if __name__ == "__main__":
email = "[email protected]" # (your email here)
password = '.....'
spreadsheet_id = "......" # (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
downloaded_spreadsheet = gs.download(ss)
# book = xlrd.open_workbook(file_contents=downloaded_spreadsheet.read(), formatting_info=True)
#It works.. alas xlrd doesn't support the xlsx-funcionality that i want...
#i.e. being able to read the cell-colordata..
我希望有人可以幫助,因爲我掙扎了幾個月獲得在谷歌電子表格的顏色數據從給定的細胞。 (我知道谷歌的API不支持它。)
+1 - 犯了類似的錯誤。我只讀了前半部分,並認爲它只能讀取文件。現在我回頭看完它,看到它也可以做類似文件的對象。 –
