Question

我写了一个函数，该函数需要凭证并连接到Google工作表。我从googlesheet中检索了数据，一切正常。由于某些原因，有时会给我一个错误。我搜索了一下，发现有一种解决方法，我在下面更改了代码。但是仍然是同样的问题。有人可以帮我吗？

那是我的代码：

scope = ['https://spreadsheets.google.com/feeds',
     'https://www.googleapis.com/auth/drive']

credentials=ServiceAccountCredentials.from_json_keyfile_name ('xxxx.json' , scope)
gc = gspread.authorize(credentials)

wks = gc.open("Test")


def network_list(request,networkname=''):

gs_client = gspread.authorize(credentials)
sheet=wks.get_worksheet(2)

if credentials.access_token_expired:
      gs_client.login()  # refreshes the token

mylist = sheet.get_all_records()

listofvm=[]
for mydict in mylist:
    # print(mydict)
    for key, value in mydict.items():

        if mydict[key] == networkname:
            # print(mydict['Network']+'  ' + mydict['IP_address'] + ' ' + str(mydict['Total_Intentes']))
            # templist.append({'Build':mydict['Build'], 'VM_Name':mydict['VM_Name']})
            # print(mydict['VM_Name'])
            if mydict['VM_Name'] not in listofvm:
                listofvm.append(mydict['VM_Name'])


return render(request, 'vm_list.html',{'listofvm':listofvm, 'networkname':networkname})

这是我下面的错误

 APIError at /

  "error": {
   "code": 401,
    "message": "Request had invalid authentication credentials. 
    Expected OAuth 2 access token, login cookie or other valid

   "status": "UNAUTHENTICATED"
    }
  }

Answer 1

好的，伙计们，我找到了答案。我只是在这里发布，可能将来有人会需要那个。所有课程都教开放Google电子表格，然后授权您的凭据，但是关键是在您请求Google工作表时更改了令牌，这就是为什么在凭据之后才请求数据放置“打开”命令的原因。我在这里输入了正确的答案，尝试了一下，效果很好。

我以前的代码

    scope = ['https://spreadsheets.google.com/feeds',
   'https://www.googleapis.com/auth/drive']

    credentials=ServiceAccountCredentials.from_json_keyfile_name ('xxxx.json' , scope)
    gc = gspread.authorize(credentials)

    wks = gc.open("Test")


    def network_list(request,networkname=''):

    gs_client = gspread.authorize(credentials)
    sheet=wks.get_worksheet(2)

    if credentials.access_token_expired:
    gs_client.login()  # refreshes the token

    mylist = sheet.get_all_records()

正确答案

    scope = ['https://spreadsheets.google.com/feeds',
    'https://www.googleapis.com/auth/drive']

     credentials=ServiceAccountCredentials.from_json_keyfile_name ('xxxx.json' , scope)
     gc = gspread.authorize(credentials)




     def network_list(request,networkname=''):

     gs_client = gspread.authorize(credentials)
     wks = gc.open("Test")
      sheet=wks.get_worksheet(2)

     if credentials.access_token_expired:
     gs_client.login()  # refreshes the token

     mylist = sheet.get_all_records()

Answer 2

默认情况下，您会在1小时内获得expires令牌，因此这就是您必须再次运行的原因：

credentials=ServiceAccountCredentials.from_json_keyfile_name ('xxxx.json' , scope)
gs_client = gspread.authorize(credentials)

或者您也可以尝试：gc.login()
