Splash与requests结合

Splash与requests结合

render.html

此接口用于获取JavaScript渲染的页面的HTML代码，接口地址就是Splash的运行地址加此接口名称，例如http://localhost:8050/render.html

import requests


def func1():
  '''
   render.html  返回一个html结果
   '''
  url = 'https://www.xxxxx.com/'
  headers = {'User-Agent': UserAgent().random}
  base_url =f'http://localhost:8050/render.html?url={url}&wait=1'
  resp = requests.get(base_url,headers=headers)
  with open('temp.html','wb') as f:
    f.write(resp.content)

render.png

此接口可以获取网页截图

import requests
 
def func2():
  '''
   render.png 返回一个截图
   '''
  url = 'https://www.xxxxx.com/'
  headers = {'User-Agent': UserAgent().random}
  base_url =f'http://localhost:8050/render.png?url={url}&wait=1'
  resp = requests.get(base_url,headers=headers)
  with open('temp.png','wb') as f:
    f.write(resp.content)

execute

最为强大的接口。前面说了很多Splash Lua脚本的操作，用此接口便可实现与Lua脚本的对接

import requests
from urllib.parse import quote
 
def func3():
  '''
   execute 执行lua脚本，返回相应的结果
   '''
  url = 'https://www.xxxxxx.com/'
  lua = f'''
   function main(splash,args)
     splash:go("{url}")
     splash:wait(1)
     return splash:html()
   end
   '''
  base_url = f'http://localhost:8050/execute?lua_source={quote(lua)}'
  resp = requests.get(base_url)
  with open('temp.html','wb') as f:
    f.write(resp.content)
