Python：身份验证、上传文件以驱动和编辑现有电子表格 - PyDrive

如何解决Python：身份验证、上传文件以驱动和编辑现有电子表格 - PyDrive

我需要在我的桌面应用程序中上传一些图像并编辑一些 Google 电子表格，并选择 PyDrive 来帮助我访问我的驱动器（当时似乎比常规 Google Api 更容易）。但是，我很难对现有电子表格进行更改，例如添加带有字符串的新行。

我能够将文件上传到 Drive 中的正确文件夹，但是我还没有找到一种以良好方式编辑表格的方法（setContentString 替换当前内容；但我需要更新内容/添加一个新的带有新字符串的行。“.GetContentString”似乎也没有按预期运行）。

应该怎么做呢？我需要下载电子表格并在 Pandas（或类似工具）中对其进行更改，还是可以在线进行？

请在下面找到我的代码：


from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from pydrive.files import GoogleDriveFile


# Try to load saved client credentials
gauth = GoogleAuth()

gauth.LoadCredentialsFile("mycreds.txt")
if gauth.credentials is None:
    # Authenticate if they're not there
    gauth.LocalWebserverAuth()
elif gauth.access_token_expired:
    # Refresh them if expired
    gauth.Refresh()
else:
    # Initialize the saved creds
    gauth.Authorize()
# Save the current credentials to a file
gauth.SaveCredentialsFile("mycreds.txt")

drive = GoogleDrive(gauth)

def uploadImage(typeInput,imgFile,listInput):
    # Determine the folder ID
    if type == "Type1":
        folderID ="folderID1"
    elif type == "Type2":
        folderID = "folderID2"


    str1 = "\'" + folderID + "\'" + " in parents and trashed=false"

    file_list = drive.ListFile({'q': str1}).GetList()
    imgTitles = []
    for file in file_list:
        q = (file['title'])
        imgTitles.append(q)
        # print(str(q))
    print(str(imgTitles))

    imgNr = imgTitles[0]
    imgNr = str(imgNr)[6:]
    imgNr = int(imgNr) + 1
    imgFileName = "Image_" + str(imgNr)

    imagetoUpload = drive.CreateFile({'parents': [{'id': folderID}]})
    imagetoUpload['title'] = imgFileName
    imagetoUpload.SetContentFile(imgFile)
    imagetoUpload.Upload()
    print('title: %s,id: %s' % (imagetoUpload['title'],imagetoUpload['id']))
    # call saveCoordsToTable
    addToTable(listInput,"typeInput","imgFileName")


def addToTable(list_input,type_input,fileName_input):
    if type == "Type1":
        fileID = "folderID1"
    elif type == "Type2":
        fileID = "folderID2"


    folderID = "FolderIDxyz"  # The folder where the Google Sheets are

    str2 = "\'" + fileID + "\'" + " in parents and trashed=false"

    GSheet = drive.CreateFile({'q': str2})

    content = GSheet.GetContentString("test.csv")
    GSheet.SetContentString(content + str(list_input,type_input)  # Should take the current content and add a string to it. I probably need to specify somehow that it is a new row,but I have no idea how.
    GSheet.Upload()

uploadImage("Type1",img.png,[1,2,3,4])

谢谢！

解决方法

您应该使用单独的库来编辑工作表。您可以使用 pygsheet 或直接使用 Google Sheets API。

对于 pygsheet，您可以使用 insert_rows 和 append_table 添加带有值的行，并使用 values.append 添加 Google 表格。

Google Sheets API 示例：link
