上傳大文件時出現 Google Drive API 400 錯誤

Question

我正在編寫一個上傳腳本，使用可恢復上傳將 CSV 文件上傳到 Google Drive 文件夾 - 正在使用它作為參考

https://developers.google.com/api-client-library/python/guide/media_upload

請參閱下面的代碼。

它似乎適用於大小 <= 20MB 的文件，但更大的文件會導致問題。

我有一個 43 MB 的 CSV 文件，我試圖使用 5 MiB 的塊大小上傳它，但在最后一個塊上傳時出現 400 錯誤：

file_meta = {'title': 'test.csv', 'description': 'Test CSV', 'mimeType': 'text/csv', 'parents': [{'id': myfolder_key}]}
convert_to_Google_Sheets = True
chunk_size = 1024*1024*5
content = <MediaIoBaseUpload object, resumable, 5 MiB chunk size>
req = drive.files().insert(body=file_meta, media_body=content, convert=convert_to_Google_Sheets)
response is None
while not response:
  status, response = req.next_chunk()
  if status:
    print "Uploaded %d%%." % int(status.progress() * 100)

上傳似乎進展順利，直到我們到達最后一個塊，當它以 400 錯誤終止時：

Uploaded 11%.
Uploaded 23%.
Uploaded 34%.
Uploaded 46%.
Uploaded 57%.
Uploaded 69%.
Uploaded 81%.
Uploaded 92%.

我遇到了同樣的問題，並一直認為問題出在文件大小上，但結果證明文件大小只是問題的產物。

問題是每個電子表格 [1] 有 200 萬個單元格的限制，當我的（也可能是你的）CSV 文件達到 20MB 左右時，列數 * 行數超過了 200 萬個單元格的限制。
