怎么用织梦来做网站后台网站建设企业咨询

1. 对东方财富官网的分析

步骤：

1. 通过刷新网页，点击等操作，我们发现https://datacenter-web.eastmoney.com/api/data/v1/get?请求后面带着一些参数即可以获取到相应数据。
2. 我们使用python来模拟这个请求即可。
   我们以如下选择的页面为切入点，以此获取当前所有A股的一些基本数据。
   

通过F12调出浏览器调试框，对该网站的数据拉取协议为参考，然后通过python模拟此类请求，进行获取数据，如下图所示：

主要代码如下：

import pandas as pd
from typing import List
import requests, jsonclass CustomedSession(requests.Session):def request(self, *args, **kwargs):kwargs.setdefault('timeout', 60)return super(CustomedSession, self).request(*args, **kwargs)MAX_CONNECTIONS = 50
session = CustomedSession()
adapter = requests.adapters.HTTPAdapter(pool_connections = MAX_CONNECTIONS,pool_maxsize = MAX_CONNECTIONS,max_retries = 5)
session.mount('http://', adapter)
session.mount('https://', adapter)# 请求地址

调用如上函数即可：
