一、前言

前几天在Python白银群【厚德载物】问了一个Python网络爬虫的问题，这里拿出来给大家分享下。

二、实现过程

这个问题其实for循环就可以搞定了，看上去粉丝的代码没有带请求头那些，导致获取不到数据。后来【瑜亮老师】、【小王子】给了具体思路，代码如下图所示：

后来【小王子】也给了一个具体代码，如下：

import requests
import time

headers = {
    "authority": "stock.xueqiu.com",
    "accept": "*/*",
    "accept-language": "zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6",
    "origin": "https://xueqiu.com",
    "referer": "https://xueqiu.com/S/SH600600",
    "sec-ch-ua": "\"Not.A/Brand\";v=\"8\", \"Chromium\";v=\"114\", \"Microsoft Edge\";v=\"114\"",
    "sec-ch-ua-mobile": "?0",
    "sec-ch-ua-platform": "\"Windows\"",
    "sec-fetch-dest": "empty",
    "sec-fetch-mode": "cors",
    "sec-fetch-site": "same-site",
    "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36 Edg/114.0.1823.51"
}
cookies = {
    "xq_a_token": "57b2a0b86ca3e943ee1ffc69509952639be342b9",
    "xqat": "57b2a0b86ca3e943ee1ffc69509952639be342b9",

    "s": "ci1eygzbit",
    "is_overseas": "0",
    "Hm_lpvt_1db88642e346389874251b5a1eded6e3": "1687872001"
}
url = "https://stock.xueqiu.com/v5/stock/quote.json"
symbols = ['SH600600', 'SH600519', 'SH301183']
for symbol in symbols:
    params = {
        "symbol": f"{symbol}",
        "extend": "detail"
    }
    response = requests.get(url, headers=headers, cookies=cookies, params=params)
    time.sleep(3)

    print(response.text)
    print(response)

代码运行之后，可以得到具体的结果，如下图所示：

【瑜亮老师】后面还补充了一个代码，如下所示：

for i in ['SH600519','SZ300600','SZ301183']:
    url = f"https://stock.xueqiu.com/v5/stock/quote.json?symbol={i}&extend=detail"
    response = requests.get(url=url, headers=headers,cookies=cookies)
    json_data = response.json()
    print(json_data)

顺利地解决了粉丝的问题。方法很多，条条大路通罗马，能解决问题就好。
