常用接口(API)

1、render.html

格式：

http://10.63.32.49:8050/render.html?url=https://www.baidu.com&wait=3.0&timeout=4

timeout超时，默认为30秒

wait 加载页面后，等待更新的时间，更新内容（ajax，js的加载，setInterval/settimeout等）

import requests

r = requests.get(
    url='http://10.63.32.49:8050/render.html?url=https://www.baidu.com')
print(r.text)

2、render.png

http://10.63.32.49:8050/render.png?url=https://www.sina.com.cn/&wait=5&width=320&height=240

图片的格式：.png

width和height决定图片的大小

import requests

r = requests.get(
    url='http://10.63.32.49:8050/render.png?url=https://search.jd.com/Search?keyword=iphone&enc=utf-8&pvid=5f6243644eeb4510b26cffce889d77a8')
# print(r.content)
with open(file='jd.png', mode='wb') as f:
    f.write(r.content)

3、render.jpeg

http://10.63.32.49:8050/render.jpeg?url=https://www.sina.com.cn/&wait=5&&quality=30

图片格式jepg

quality为图片的质量，默认75，类型：integer 范围 0~100，不应该超过95

也有width和height

4、render.har

http://10.63.32.49:8050/render.har?url=https://search.jd.com/Search?keyword=iphone&enc=utf-8&pvid=5f6243644eeb4510b26cffce889d77a8

获取页面加载的HAR数据。结果JSON

import requests
import json

r = requests.get(
    url='http://10.63.32.49:8050/render.har?url=https://search.jd.com/Search?keyword=iphone&enc=utf-8&pvid=5f6243644eeb4510b26cffce889d77a8')

# print(r.json())

with open(file='a.json', mode='w') as f:
    f.write(json.dumps(r.json()))

5、render.json

http://10.63.32.49:8050/render.json?url=https://search.jd.com/Search?keyword=iphone&enc=utf-8&pvid=5f6243644eeb4510b26cffce889d77a8

获取接口的所有功能，返回结果JSON

import requests
import json

r = requests.get(
    url='http://10.63.32.49:8050/render.json?url=https://search.jd.com/Search?keyword=iphone&enc=utf-8&pvid=5f6243644eeb4510b26cffce889d77a8')

# print(r.json())

with open(file='b.json', mode='w') as f:
    f.write(json.dumps(r.json()))

 6、execute

http://10.63.32.49:8050/execute?lua_source=

作用：用Lua实现和页面的交互操作

from urllib.parse import quote
import requests

lua = """
    function main(splash)
        return "hello"
    end
"""

lua_url = quote(lua)
# print(lua_url)
r = requests.get('http://10.63.32.49:8050/execute?lua_source={}'.format(lua_url))
print(r.text)

 返回lua脚本执行后的结果
