問題分析

通過HttpClient獲取網(wǎng)頁數(shù)據(jù)源，通過Jsoup解析數(shù)據(jù)。先模擬登錄統(tǒng)一身份認(rèn)證平臺，再通過單點登錄方式登錄正方教務(wù)系統(tǒng)，最后獲取相關(guān)信息。模擬瀏覽器正常操作，封裝請求頭信息獲取SESSIONID。

登錄統(tǒng)一身份認(rèn)證平臺

登錄請求表單數(shù)據(jù)?

密鑰與加密密碼均為Base64編碼

?

常見加密：

1）數(shù)據(jù)加密標(biāo)準(zhǔn)（DES Data Encryption Standard)：DES（密鑰長度64位）（ECB模式）

2）分組密碼算法：AES（密鑰長度在128位及以上）（GCM或CBC模式）

3）流密碼算法：AES（密鑰長度在128位及以上）（OFB或CTR模式）、chacha20

4）哈希算法：SHA2、SHA3

5）密鑰交換算法：DSA/DH（密鑰長度2048位及以上)、ECDH（密鑰長度223及以上）

6）HMAC（基于哈希的消息驗證碼）算法：HMAC-SHA2

7）非對稱加密算法：RSA（2048位及以上)、ECC（256位以上）

DEC解密?

此統(tǒng)一身份認(rèn)證平臺密碼加密采用DES/ECB/PKCS7Padding方式加密。

相關(guān)加密解密方法，自行百度。
