PHP API接口签名验证

时间：2024-10-18 08:04:02

hash_hmac

在php中hash_hmac函数就能将HMAC和一部分哈希加密算法相结合起来实现HMAC-SHA1  HMAC-SHA256 HMAC-MD5等等算法。函数介绍如下：
string hash_hmac(string $algo, string $data, string $key, bool $raw_output = false)
algo：要使用的哈希算法名称，可以是上述提到的md5,sha1等
data：要进行哈希运算的消息，也就是需要加密的明文。
key：使用HMAC生成信息摘要是所使用的密钥。
raw_output：该参数为可选参数，默认为false，如果设为true，则返回原始二进制数据表示的信息摘要，否则返回16进制小写字符串格式表示的信息摘要（注意是16进制数，而非简单的字母加数字）。
另外：如果algo参数指定的不是受支持的算法，将返回false

/**

 * 生成 哈希签名

 * 生成签名步骤&例子如下

 * 0.需要加密的数据：

 * array

 * (

 *    [b] => 1

 *    [B] => 2

 *    [d] => Array

 *          (

 *              [id] => 1

 *           )

 *    [a] => 3

 * )

 * 1. 对需要加密的参数进行字典排序

 * array

 * (

 *    [B] => 2

 *    [a] => 3

 *    [b] => 1

 *    [d] => Array

 *          (

 *              [id] => 1

 *           )

 * )

 * 2. 将Key和Value拼接成字符串（如果值为数组不参与拼接）

 * B=2a=3b=1

 * 3. 拼接字符串全部转为小写

 * b=2a=3b=1

 * 4. 使用hmac的md5加密算法，并且使用token对拼接字符串进行加密【token为luo生成加密数据如下：】
