Google Sheets API for python2.7 -->“无效的JSON有效负载。根元素必须是消息”
Google Sheets API for python2.7 -->“无效的JSON有效负载。根元素必须是消息”
提问于 2018-08-21 01:45:42
几个星期以来，我一直在与这个错误作斗争，并尝试了之前发布的与Python API for Google Sheets相关的问题的解决方案。
当我通过python的Google Sheets API向我的电子表格发出“写入”请求时，我不断地收到一个错误。错误提示我提交了一个无效的JSON，但是我已经在交互式测试窗口(Google APIs Explorer)上测试了JSON结构，并且来自那里的请求正确地更新了我的工作表。
代码如下
from __future__ import print_function
from apiclient.discovery import build
from httplib2 import Http
from oauth2client import file, client, tools
import datetime
import json
# Call the Sheets API
SPREADSHEET_ID = #mySheetID
RANGE_NAME = '2018_Raw Data!A3:A367'
months = { 0:"Jan", 1:"Feb",2:"Mar",4:"Apr",5:"May",6:"Jun",7:"Jul",8:"Aug",9:"Sep",10:"Oct",11:"Nov",12:"Dec"}
now = datetime.datetime.now()
date = str(now.day) +"-"+ months[now.month] + "-"+str(now.year)
day_of_year = now.timetuple().tm_yday
myRow = day_of_year+2
print (date)
print (myRow)
BWRange= '2018_Raw Data!B' + str(myRow)
BFRange= '2018_Raw Data!C' + str(myRow)
myBodyWeight=150
myBF="10%"
print (BWRange)
print (BFRange)
BWData = {}
BWData['values']= [[myBodyWeight]]
BWData['majorDimension']="ROWS"
BWData['range']= BWRange
BWJson= json.dumps(BWData)
BFData = {}
BFData['values']= [[myBF]]
BFData['majorDimension']="ROWS"
BFData['range']= BFRange
BFJson= json.dumps(BFData)
print (BWJson)
print (BFJson)
# Setup the Sheets API
SCOPES = 'https://www.googleapis.com/auth/spreadsheets'
store = file.Storage('token.json')
creds = store.get()
if not creds or creds.invalid:
flow = client.flow_from_clientsecrets('credentials.json', SCOPES)
creds = tools.run_flow(flow, store)
service = build('sheets', 'v4', http=creds.authorize(Http()))
#bw
request = service.spreadsheets().values().update(spreadsheetId=SPREADSHEET_ID,range=BWRange, valueInputOption="USER_ENTERED", body=BWJson)
response = request.execute()
pprint(response)
#bf
request = service.spreadsheets().values().update(spreadsheetId=SPREADSHEET_ID, range=BFRange,valueInputOption="USER_ENTERED", body=BFJson)
response = request.execute()
pprint(response)错误如下：
Traceback (most recent call last):
File "C:\sheets\mySheets.py", line 65, in <module>
response = request.execute()
File "C:\Python27\lib\site-packages\googleapiclient\_helpers.py", line 130, in positional_wrapper
return wrapped(*args, **kwargs)
File "C:\Python27\lib\site-packages\googleapiclient\http.py", line 842, in execute
raise HttpError(resp, content, uri=self.uri)
googleapiclient.errors.HttpError: <HttpError 400 when requesting https://sheets.googleapis.com/v4/spreadsheets/1demD8sm5-Jvi7ImHcOu03sHaU7PF61ym1eyvjN1bGfw/values/2018_Raw%20Data%21B234?alt=json&valueInputOption=USER_ENTERED returned "Invalid JSON payload received. Unknown name "": Root element must be a message.">我评论了下面的帖子：

我认为您的请求正文是正确的。那么这个修改怎么样呢？
发自：
request = service.spreadsheets().values().update(spreadsheetId=SPREADSHEET_ID,range=BWRange, valueInputOption="USER_ENTERED", body=BWJson)
request = service.spreadsheets().values().update(spreadsheetId=SPREADSHEET_ID, range=BFRange,valueInputOption="USER_ENTERED", body=BFJson)至：
request = service.spreadsheets().values().update(spreadsheetId=SPREADSHEET_ID,range=BWRange, valueInputOption="USER_ENTERED", body=BWData)
request = service.spreadsheets().values().update(spreadsheetId=SPREADSHEET_ID, range=BFRange,valueInputOption="USER_ENTERED", body=BFData)注意：
- 在此修改中，删除了
json.dumps()。 - 此脚本假定在API控制台启用了Sheets API，并且您的访问令牌可用于Sheets
如果这个不起作用，请告诉我。我想修改一下。
