python 爬蟲下載跳轉問題？狀態(tài)碼總是302？用瀏覽器手動下載就沒有任何問題？

1.我在某個網(wǎng)頁里獲得了某個下載地址A，用瀏覽器點擊它的時候，總是會跳轉到真實下載地址B，而且瀏覽器開始自動幫助你下載，用瀏覽器表示一切都是正常的，但是我用自己寫的爬蟲程序，總是找不到真實的下載地址B，總是顯示狀態(tài)碼302？下載的種子文件大小還是0？
2.這是我自己的代碼：

response = requests.get(url,headers=headers)
html = etree.HTML(response.text)
hrefs ='http://www.gawu88.space/'+ html.xpath('//p[@class="attnm"]/a/@href')[0]
req = requests.get(hrefs)
print(req.status_code)
file_name = "f:/1.torrent"
with open(file_name,"wb") as f:

f.write(req.content)
f.close()

3.其中req就是網(wǎng)頁中解析出來的A地址，用瀏覽器訪問，能夠得到真實下載地址B，用自己的程序總是獲取不到真實下載地址，我想請各位朋友能夠幫我看看，感激不盡。requests不是能夠自動幫助解決跳轉問題么？為什么打印req.url顯示的還是原來的地址？最后再次感謝各位朋友。
