本实施例中以AES加密算法为例，也可以是其他加密算法，如： DES算法 ， 3DES 算法， TDEA 算法等。 In this embodiment, the AES encryption algorithm is taken as an example, and other encryption algorithms may also be used, such as: DES algorithm, 3DES algorithm, TDEA. Algorithms, etc.
在步骤 S103 中， 将加密后的统一资源定位符 URL 采用压缩算法进行压缩，并进行 Base64 编码。 In step S103, the encrypted uniform resource locator URL is compressed by a compression algorithm, and is performed on Base64. Coding.
该压缩算法可以是 zlib 库提供的封装对外接口，也可以为 haffman 算法、 RLE 算法、 LZ77 算法等；由于压缩后的 URL 其中会包含一些 HTTP 协议不可识别的字符，因此要将 URL 进行 Base64 编码，使得其可用于在 HTTP 环境下传递。 The compression algorithm can be a package external interface provided by the zlib library, or a haffman algorithm, an RLE algorithm, LZ77 algorithm, etc.; because the compressed URL contains some characters that are not recognized by the HTTP protocol, the URL is Base64 encoded so that it can be used in HTTP Passed under the environment.
在步骤 S104 中， 将编码后的统一资源定位符 URL 发送给服务器。 In step S104, the encoded uniform resource locator URL is sent to the server.
由于传统的防盗链的做法只是将 URL 经过秘钥加密就进行网络传输，这样黑客截获到 URL 后，很容易就将加密的 URL 破译，安全性不高，本发明在加密的 URL 基础上在用压缩算法进行压缩，提高了 URL 传输的安全性。 Because the traditional anti-theft chain only performs the network transmission by encrypting the URL with the secret key, the hacker intercepts the URL. After that, the encrypted URL is easily deciphered and the security is not high. The present invention compresses the compressed algorithm based on the encrypted URL, thereby improving the security of the URL transmission.
