【已解决】Python中用requests获取到一个url地址的302跳转后的真正有效地址

折腾：

【未解决】自动化搜索和提取安卓游戏网站game.vivo.com.cn中游戏信息列表

期间，需要去获取

http://dl.gamecenter.vivo.com.cn/clientRequest/gameDownload?id=55002&pkgName=com.tatuyin.rxsg.vivo&sourword=%E4%B8%89%E5%9B%BD&page_index=2&dlpos=1&channel=h5

这种临时的下载地址，经过302跳转后的真正的地址：

去Chrome中分析就是：

此处去试试代码实现

python requests 302

Requests and the HTTP 302 Status Code • Lukasa’s Echochamber

设置allow_redirects为false？即可？

redirect – python requests handle error 302? – Stack Overflow

去看看resp.history

http – Python Requests library redirect new url – Stack Overflow

感觉还是：不让跳转更好?

r = requests.get('http://github.com/', allow_redirects=False)

去试试

def get302RealUrl(originUrl):
    realUrl = ""
    resp = requests.get(originUrl, allow_redirects=False)
    if resp.status_code == 302:
        realUrl = resp.headers['Location']
    return realUrl

即可：

然后提取到库中：

import requests

def get302RealUrl(originUrl):
    """get real url address after 302 move


    Args:
        originUrl (str): original url
    Returns:
        real url(str)
    Raises:
    Examples:
        input: 'http://dl.gamecenter.vivo.com.cn/clientRequest/gameDownload?id=57587&pkgName=com.jiuzun.mxsg.vivo&sourword=%E4%B8%89%E5%9B%BD&page_index=4&dlpos=1&channel=h5'
        output: 'https://gameapktxdl.vivo.com.cn/appstore/developer/soft/20180206/201802061851104837232.apk'
    """
    realUrl = ""
    resp = requests.get(originUrl, allow_redirects=False)
    if resp.status_code == 302:
        realUrl = resp.headers['Location']
    return realUrl
