python 获取酸酸乳的账号密码

科学上网，需要到SSR的账号密码，有时候每次都要去查，比较麻烦，写个脚本爬取数据，保存到配置文件。

首先看看配置文件json结构如下：

{
    "configs": [
       
        {
            "remarks": "xxxx", 
            "id": "BED33E45B9D8972248846237E8B938C2", 
            "server": "xxxx",  //这里隐藏了server ip 地址
            "server_port": "12259", 
            "server_udp_port": 0, 
            "password": "85973970", 
            "method": "aes-256-cfb", 
            "protocol": "auth_sha1_v4", 
            "protocolparam": "", 
            "obfs": "tls1.2_ticket_auth", 
            "obfsparam": "", 
            "remarks_base64": "U1NSMQ", 
            "group": "SSR", 
            "enable": true, 
            "udp_over_tcp": false
        }
    ], 
    
}

需要到数据是
server，server_port，password，method，protocol，obfs
这几个数据。

查看目标数据：

再看看网页目标html 结构：

蓝色部分就是我们对应的位置。

接下来是代码部分
需要工具：

• python3.5
• bs4

#coding=utf-8

from bs4 import BeautifulSoup
from urllib.request import urlopen
import json

# crawler get data
def ssr():
    url="https://www.abc.com/" # 隐藏了酸酸乳网址
    user_agent ="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36"
    header = {'User-Agent':user_agent}
    try:
        page = urlopen(url)
        soup = BeautifulSoup(page,"html.parser")
        items = soup.find_all("div",class_="portfolio-item") 
        target_item = items[11]
        # 找到目标节点获取数据
        ipssrc=target_item.find(id="ipssrc").string.lstrip()
        portssrc=target_item.find(id="portssrc").string.strip('\n')
        pwssrc=target_item.find(id="pwssrc").string.strip('\n')
        h4s = target_item.find_all("h4")
        method = h4s[3].string.split(":")[1].lstrip()
        temp = h4s[4].string.split(" ")
        protocol = temp[0].lstrip()
        obfs = temp[1].lstrip()
        #调用saveData()保存数据
        saveData(ipssrc,portssrc,pwssrc,method,protocol,obfs)
        
    except Exception as e:
        raise e

def saveData(ipssrc,portssrc,pwssrc,method,protocol,obfs):
    
    #打开读取json文件
    with open('gui-config.json',mode='r+', encoding='utf-8') as f:
        data = json.load(f)
        configs = data['configs']
        #设置对应信息
        ssr = configs[2]
        ssr['remarks'] = ipssrc
        ssr['server'] = ipssrc
        ssr['server_port'] = portssrc
        ssr['password'] = pwssrc
        ssr['method'] = method
        ssr['protocol'] = protocol
        ssr['obfs'] = obfs
    #保存json数据到文件
    with open("gui-config.json",mode="w") as f:
        json.dump(data,f)

if __name__ == '__main__':
    ssr()
