大家好，關于在線urldecode很多朋友都還不太明白，今天小編就來為大家分享關于在線獲取圖片url地址的知識，希望對各位有所幫助！
如何解決jsp中通過url傳遞中文參數亂碼問題
第一步：在tomcat的server.xml文件中設置web服務器端口配制中加下面兩句：useBodyEncodingForURI="true"URIEncoding="UTF-8"第二步：JSP頁面編碼用UTF-8(也可以用“gb2312"，第一步與解碼要一至）傳值時編碼一下：以傳遞的參數為strPar為例，在傳遞數據前將strPar進行編碼java.net.URLEncoder.encode(strPar,"UTF-8");第二步：解碼在獲取數據服務器端Action中得到的strPar進行解碼java.net.URLDecoder.decode(strPar,"UTF-8");本人測試時傳入action中可以不解碼也正常。舉例：Url傳值：

url加密和解密方案
你好，URL加密和解密方案是將URL中的敏感信息進行加密，以保護數據安全。以下是幾種常見的URL加密和解密方案：
1.對稱加密：使用相同密鑰對URL進行加密和解密。常見的對稱加密算法有AES、DES等。加密和解密過程速度快，但密鑰的安全性需要保證。
2.非對稱加密：使用公鑰加密URL，再使用私鑰解密。公鑰可公開，私鑰保密。常見的非對稱加密算法有RSA、DSA等。安全性較高，但加密和解密過程較慢。
3.散列函數：將URL通過散列函數進行加密，生成固定長度的散列值。常見的散列函數有MD5、SHA-1、SHA-256等。加密過程不可逆，但不能解密，只能通過對比散列值來驗證URL的正確性。
4.Base64編碼：將URL進行Base64編碼，將原始URL轉換為一串字符。編碼過程是可逆的，解碼可以還原原始URL，但不具有真正的加密功能，只是一種簡單的編碼方式。
選擇合適的加密和解密方案應根據實際需求和安全性要求來進行。

phpurldecode怎么用
urlencode()編碼：對字符串中除了-_.之外的所有非字母數字字符都將被替換成百分號（%）后跟兩位十六進制數，空格則編碼為加號（+）。urldecode()解碼：還原URL編碼字符串。示例：
