Python 3间断ssl.SSLEOFError

Question

我每 90 秒使用 pygsheets python 模块从 google 张中获取数据。

在清晨（通常是凌晨 2 点到 3 点之间）此操作失败，并且我记录了此错误：

Traceback (most recent call last):
  File "/etc/naemon/naemon-automation/exec/pull-GSheets-CSV.py", line 42, in <module>

我的代码：

import pygsheets
import sys
from pathlib import Path

# Import Arguments required for generating Configuration. If one is not set - Do not continue
# str(sys.argv[1]) # Argument denoting the Google Service Account API Authentication File
# str(sys.argv[2]) # Argument denoting the Google Sheets URL Key found when logging into the Google Sheets Manually via browser
# str(sys.argv[3]) # Argument denoting the Google Worksheet Name, for unique identification within the Google Spreadsheet
# str(sys.argv[4]) # Argument denoting the File Name and output destination

# Variable Definitions
try:
        gServiceAccAuthFile = str(sys.argv[1])
        gSheetKey = str(sys.argv[2])
        gWorksheetName = str(sys.argv[3])
        outputFile = str(sys.argv[4])
        outputDir = str(Path(outputFile).parents[0])
        outputFileName = str(Path(outputFile).stem)
except IndexError:
        print('Not enough Arguments Specified, Required Arguments:\nPOS 1.)\tGoogle Service Account API Authentication File\nPOS 2.)\tGoogle Sheets URL Key\nPOS 3.)\tGoogle Worksheet Name\nPOS 4.)\tOutput File Path & Name')
        sys.exit()

# Authorize Spreadsheet Access
gc = pygsheets.authorize(service_file=gServiceAccAuthFile, retries=1)
# Open spreadsheet
sh = gc.open_by_key(gSheetKey)
# Open Worksheet
wks = sh.worksheet_by_title(gWorksheetName)
# Export as CSV
wks.export(pygsheets.ExportType.CSV, path=outputDir + '/', filename=outputFileName)

建议的解决方案：

SSL 模块问题：更新到较新的二进制文件？
Try / except：except 语句是什么？ except ssl.SSLEOFError?
Pygsheets：是否有 wks.export() retry 函数？

Answer 1

Try / except: What would be the except statement? except ssl.SSLEOFError?
Pygsheets: Is there a wks.export() retry function?

结合这些 – 我正在使用 logging 进行日志记录，但可以根据需要进行调整。

import ssl
import logging

log = logging.getLogger(...)

for attempt in range(1, 6):  # Try at most 5 times
   try:
       wks.export(pygsheets.ExportType.CSV, path=outputDir + '/', filename=outputFileName)
   except ssl.SSLError as e:
       log.warning('Attempt %d to export sheet failed: %s' % (attempt, e), exc_info=True)
   else:
       break  # success!
else:  # executed if we didn't `break` out
    raise RuntimeError('All attempts to export the sheet failed!')
