在utils中的util.js 文件中增加 函数 实现 字符串转换为16进制加密后的字符串
function encodeUTF8(s) {
var i, r = [], c, x;
for (i = 0; i < s.length; i++)
if ((c = s.charCodeAt(i)) < 0x80) r.push(c);
else if (c < 0x800) r.push(0xC0 + (c >> 6 & 0x1F), 0x80 + (c & 0x3F));
else {
if ((x = c ^ 0xD800) >> 10 == 0) //对四字节UTF-16转换为Unicode
c = (x > 18 & 0x7), 0x80 + (c >> 12 & 0x3F));
else r.push(0xE0 + (c >> 12 & 0xF));
r.push(0x80 + (c >> 6 & 0x3F), 0x80 + (c & 0x3F));
};
return r;
};
// 字符串加密成 hex 字符串
function sha1(s) {
var data = new Uint8Array(encodeUTF8(s))
var i, j, t;
var l = ((data.length + 8) >>> 6 |
