Amazon Affiliate Link Builder python脚本崩溃？

Question

我真的很奇怪为什么有时候我的python脚本会崩溃。

def returnAmazonLink(link):

    if 'amazon.de' in link:
        art, tracking_id, endung = 'amazon-ref.de', 'myID', '.de'
    elif 'amazon.co.uk' in link:
        art, tracking_id, endung = 'amazon-ref.co.uk', 'myID', '.co.uk'
    elif 'amazon.es' in link:
        art, tracking_id, endung = 'amazon-ref.es', 'myID', '.es'
    elif 'amazon.fr' in link:
        art, tracking_id, endung = 'amazon-ref.fr', 'myID', '.fr'
    elif 'amazon.it' in link:
        art, tracking_id, endung = 'amazon-ref.it', 'myID', '.it'
    else:
        art = 'amazon-ERROR'
        offer_link = link
        return offer_link, art

    try:
        split_a = link.split('/dp/')
        asin = split_a[1][0:10]
        offer_link = 'https://www.amazon'+ endung +'/dp/' + asin + '/?tag=' + tracking_id
    except:
        try:
            split_b = link.split('/product/')
            asin = split_b[1][0:10]
            offer_link = 'https://www.amazon'+ endung+'/gp/product/' + asin + '/?tag=' + tracking_id
        except:
            split_c = link.split('/offer-listing/')
            asin = split_c[1][0:10]
            offer_link = 'https://www.amazon'+ endung +'/gp/offer-listing/' + asin + '/?tag=' + tracking_id

    return offer_link, art

我希望在调用像returnAmazonLink这样的方法时获得亚马逊会员url

示例输入可以是：https://www.amazon.de/Marshall-Tufton-Tragbarer-Lautsprecher-Schwarz/dp/B07PZCRG6X?pf_rd_p=fd924cef-3db6-4a05-a84c-ae526862ddd8&pd_rd_wg=2ga3n&pf_rd_r=T28M0D83M3NG8JJVX04K&ref_=pd_gw_cr_simh&pd_rd_w=NmDeI&pd_rd_r=3974ee63-3d1d-4b9e-b536-b5bd73e18b3f

它只是有时会崩溃。并不是一直都这样。我认为问题出在try catches上，因为这在出现的错误消息中也有说明。

但它向我显示了错误，正如您在图像中看到的那样。enter image description here

我真的希望你们能帮助我！非常感谢

我认为编写一个exception base code是一件很痛苦的事情

您的输入可能不包含'/dp/‘、'/product/’或'/offer-listing/‘中的任何一个，这就造成了问题

我会试着这样做：

if '/dp/' in link:
    split_a = link.split('/dp/')
    asin = split_a[1][0:10]
    offer_link = 'https://www.amazon'+ endung +'/dp/' + asin + '/?tag=' + tracking_id
elif '/product/' in link:
    split_b = link.split('/product/')
    asin = split_b[1][0:10]
    offer_link = 'https://www.amazon'+ endung+'/gp/product/' + asin + '/?tag=' + tracking_id
elif '/offer-listing/' in link:
    split_c = link.split('/offer-listing/')
    asin = split_c[1][0:10]
    offer_link = 'https://www.amazon'+ endung +'/gp/offer-listing/' + asin + '/?tag=' + tracking_id
else:
    print('There was an error! check this link:')
    print(link)
    art = 'amazon-ERROR'
    offer_link = link
