• render.html

  render.html 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。
  http://0.0.0.0:8050/render.html?url=https://www.baidu.com&wait=5
  http://0.0.0.0:8050      +       render.html      +        url=https://www.baidu.com       +       wait=5

  

  import requests
  
  url = ‘http://0.0.0.0:8050/render.html?url=https://www.baidu.com&wait=5‘
  response = requests.get(url)
  print(response.text)
  
  
  # 运行
  给此接口传递了一个url参数来指定渲染的URL，等待5秒钟，返回结果即页面渲染后的源代码。

• render.png

  render.png 接口可以获取网页截图，通过 width 和 height 来控制宽高，它返回的是PNG 格式的图片二进制数据。

  http://localhost:8050/render.png?url=https://www.jd.com&wait=5&width=1000&height=700

  http://localhost:8050/render.png?url=https://www.jd.com&wait=5&width=1000&height=700

  

  import requests
  
  url = ‘http://localhost:8050/render.png?url=https://www.jd.com&wait=5&width=1000&height=700‘
  response = requests.get(url)
  with open(‘taobao.png‘, ‘wb‘) as f:
      f.write(response.content)

  import requests
  
  url = ‘http://localhost:8050/render.har?url=https://www.jd.com&wait=5‘
  response = requests.get(url)
  with open(‘jd1.json‘, ‘wb‘) as f:
      f.write(response.content)
  
  
  # 运行生成一个名为jd.json的文件

• execute

  最强大的接口

  

  import requests
  from urllib.parse import quote
  
  # lua脚本
  lua = ‘‘‘
  function main(splash)
      return ‘hello‘
  end
  ‘‘‘
  
  # quote()方法将lua脚本进行URL转码。lua_source作为参数传递
  url = ‘http://localhost:8050/execute?lua_source=‘ + quote(lua)
  
  response = requests.get(url)
  print(response.text)
  print(quote(lua))
  
  
  # 输出：
