树莓派自动连接wifi的python脚本 [英] python script for RaspberryPi to connect wifi automatically

问题描述

我想用 RaspberryPi 操作 WiFi dongle，(就像一个没有内置 WiFi 的 CPU).我需要编写一个 python 脚本来自动扫描 WiFi 网络，并且需要使用已知的 SSID 和密码自动建立连接.

I want to operate a WiFi dongle with RaspberryPi, (it's like a CPU without built-in WiFi). I need to write a python script which automatically scan for WiFi networks and a connection need to be automatically established with known SSID and password.

这意味着我需要从文件中提供 WiFi 网络的密码，并且剩下的就是自动扫描和连接了.

This mean that I need to provide the password for the WiFi network from a file, and the remaining thing is to do the scanning and connecting automatically.

我从网上读取了一个包含 WiFi SSID 名称和密码的文件.

I read a file from the Web which contains WiFi SSID name and password.

我需要编写一个脚本来扫描并列出当前的网络，并将其与文件中的 SSID 进行匹配，并进一步自动创建与该已知网络的连接.

I need to write a script which scan and list current networds and match it to the SSID from the file and further to automatically create the connection to this known network.

RaspberryPi 操作系统:Rasbian

RaspberryPi OS: Rasbian

推荐答案

谢谢大家的回答 我做了如下简单的解决方案

Thank you all for your answers i made simple solution like below

def wifiscan():

   allSSID = Cell.all('wlan0')
   print allSSID # prints all available WIFI SSIDs
   myssid= 'Cell(ssid=vivekHome)' # vivekHome is my wifi name

   for i in range(len(allSSID )):
        if str(allSSID [i]) == myssid:
                a = i
                myssidA = allSSID [a]
                print b
                break
        else:
                print "getout"

   # Creating Scheme with my SSID.
   myssid= Scheme.for_cell('wlan0', 'home', myssidA, 'vivek1234') # vive1234 is the password to my wifi myssidA is the wifi name 

   print myssid
   myssid.save()
   myssid.activate()

wifiscan()
