不知道你的JS怎么写的 是这样 比如那两个Java字节数组 写到js里需要像下面这样子: var bArr = [70, 70, 72, 75, 90, 89, 76, 75, 65].map(c => c >= 0 ? c : 0xff+c+1);
var bArr2 = [0, 0, 0, 0, 3, 73, 98, -37].map(c => c >= 0 ? c : 0xff+c+1); 用这里的 sha1hmac.js 举个例子(看最后面3行) 算出结果是 '4607437b052871aa1653b0e82c78f8436d6d97d2' 这个结果跟Java里[ 70 , 7 , 67 , 123 , 5 , 40 , 113 , - 86 , 22 , 83 , - 80 , - 24 , 44 , 120 , - 8 , 67 , 109 , 109 , - 105 , - 46 ] 是一模一样的。
