python的新手，所以它可能很简单。Raspberry Pi 4，运行 apache 并连接了 CGI。Speedtest-cli 已安装并且工作正常。我可以在 Putty 中毫无问题地运行下面的脚本。但是当我尝试在 cgi-bin 中运行它进行测试时，我在这一行得到一个错误：

打印 ping.group(1)

错误：<type 'exceptions.AttributeError'>：'NoneType' 对象没有属性 'group'

它似乎跳过了调用 speedtest 的行： response = subprocess.Popen('/usr/bin/speedtest', shell=True, stdout=subprocess.PIPE).stdout.read().decode('utf- 8')

同样，这在 Putty 中运行良好。


#!/usr/bin/python
print ('Content-Type: text/html')
print

import os
import re
import subprocess
import time
import cgi, cgitb
cgitb.enable()

try:

        while(True):

           print("\rGetting data")
           print("------------------------------------")
           response = subprocess.Popen('/usr/bin/speedtest', shell=True, stdout=subprocess.PIPE).stdout.read().decode('utf-8')
                 #print(response)

           ping = re.search("Latency:\s+(.*?)\s+", response, re.MULTILINE)
           download = re.search("Download:\s+(.*?)\s", response, re.MULTILINE)
           upload =  re.search("Upload:\s+(.*?)\s", response, re.MULTILINE)

           ping = ping.group(1)
           download = download.group(1)
           upload = upload.group(1)

           print("Ping: " + ping + " m/s")
           print("Download: " + download + " mb/s")
           print("Upload: " + upload + " mb/s")
           time.sleep(1810)
           print("\r\n\r\n")

except:
        cgitb.handler()
