獲取百度網盤下載真實地址
阿新 • • 發佈：2019-02-05
這是一個java寫的獲取百度網盤真實下載連結進行下載的程式。
程式裡面一些引數拼接是根據瀏覽器抓包來的。具體的抓包方法網上一大堆，可以參考。這裡給出了原始碼和匯出的jar包。
url網址使用於百度分享的地址。暫時沒有適配有提取碼的地址。
執行的方法：
1、在當前的目錄開啟cmd，預設不帶引數就是用預設的測試的url。
java -jar BaiduPanURL.jar
2、如果想使用自己定義的資源地址可以在後面加一個引數。
java -jar BaiduPanURL.jar your_url
注意：百度網盤同一個ip進行3次下載之後就需要驗證碼。程式會在當前的目錄生成驗證碼，輸入正確的驗證碼後可以進行下載。
本人親測有效，百度會限制下載的速率，測試只有100kb左右。
