CURL擷取重新導向URL

使用CURL擷取下面連結重新導向URL：
http://www.amazon.com/Bengoo-Portable-Desktop-Electric-Rechargeable/dp/tech-data/B01F70ZGYW%3FSubscriptionId%3DAKIAJWXT2MCY6ZQDW7VQ%26tag%3DASSOCIATETAG%26linkCode%3Dsp1%26camp%3D2025%26creative%3D386001%26creativeASIN%3DB01F70ZGYW
我抓取到重新導向後的連結還是這條url。
而實際的URL為：
http://www.amazon.com/dp/B01F70ZGYW?_encoding=UTF8&SubscriptionId=AKIAJWXT2MCY6ZQDW7VQ&showDetailTechData=1&tag=ASSOCIATE#technical-data
