1.訪(fǎng)問(wèn)某個(gè)網(wǎng)頁(yè)，用瀏覽器可以下載其中嵌入的種子文件，種子文件大小是正常的，用迅雷工具也可以正常下載，但是用python爬蟲(chóng)爬取，并且下載下來(lái)的數(shù)據(jù)大小為0？
2.這是我自己寫(xiě)的代碼。

3.如果我不加入headers，雖然下載下來(lái)的種子數(shù)據(jù)不再為0，但是下載的種子文件是一個(gè)空文件，里面沒(méi)有下載數(shù)據(jù)。
4.我想知道的是為什么不能夠下載種子文件，有沒(méi)有什么解決方法？還是我的請(qǐng)求頭headers構(gòu)造有問(wèn)題？希望各位朋友能夠幫忙解決一下。謝謝。
