把上一步获取到的 sub_key 拼接在 img_key 后面（下例记为 raw_wbi_key），遍历重排映射表 MIXIN_KEY_ENC_TAB，取出 raw_wbi_key 中对应位置的字符拼接得到新的字符串，截取前 32 位，即为 mixin_key。
重排映射表 MIXIN_KEY_ENC_TAB 长为 64，内容如下：
const MIXIN_KEY_ENC_TAB: [u8; 64] = [
46, 47, 18, 2, 53, 8, 23, 32, 15, 50, 10, 31, 58, 3, 45, 35, 27, 43, 5, 49,
33, 9, 42, 19, 29, 28, 14, 39, 12, 38, 41, 13, 37, 48, 7, 16, 24, 55, 40,
61, 26, 17, 0, 1, 60, 51, 30, 4, 22, 25, 54, 21, 56, 59, 6, 63, 57, 62, 11,
36, 20, 34, 44, 52
]
重排操作如下例：
fn gen_mixin_key(raw_wbi_key: impl AsRef<[u8]>) -> String {
const MIXIN_KEY_ENC_TAB: [u8; 64] = [
46, 47, 18, 2, 53, 8, 23, 32, 15, 50, 10, 31, 58, 3, 45, 35, 27, 43, 5, 49, 33, 9, 42,
19, 29, 28, 14, 39, 12, 38, 41, 13, 37, 48, 7, 16, 24, 55, 40, 61, 26, 17, 0, 1, 60,
51, 30, 4, 22, 25, 54, 21, 56, 59, 6, 63, 57, 62, 11, 36, 20, 34, 44, 52,
];
let raw_wbi_key = raw_wbi_key.as_ref();
let mut mixin_key = {
let binding = MIXIN_KEY_ENC_TAB
.iter()
// 此步操作即遍历 MIXIN_KEY_ENC_TAB，取出 raw_wbi_key 中对应位置的字符
.map(|n| raw_wbi_key[*n as usize])
// 并收集进数组内
.collect::<Vec<u8>>();
unsafe { String::from_utf8_unchecked(binding) }
};
let _ = mixin_key.split_off(32); // 截取前 32 位字符
mixin_key
}
如 img_key -> 7cd084941338484aae1ad9425b84077c、sub_key -> 4932caff0ff746eab6f01bf08b70ac45 经过上述操作后得到 mixin_key -> ea1db124af3c7062474693fa704f4ff8。
计算签名（即 w_rid）
若下方内容为欲签名的原始请求参数（以 JavaScript Object 为例）
{
foo: '114',
bar: '514',
zab: 1919810
}
wts 字段的值应为当前以秒为单位的 Unix 时间戳，如 1702204169
复制一份参数列表，添加 wts 参数，即：
{
foo: '114',
bar: '514',
zab: 1919810,
wts: 1702204169
}
随后按键名升序排序后百分号编码 URL Query，拼接前面得到的 mixin_key，如 bar=514&foo=114&wts=1702204169&zab=1919810ea1db124af3c7062474693fa704f4ff8，计算其 MD5 即为 w_rid。
需要注意的是：如果参数值含中文或特殊字符等，编码字符字母应当大写 （部分库会错误编码为小写字母），空格应当编码为 %20（部分库按 application/x-www-form-urlencoded 约定编码为 +）, 具体正确行为可参考 encodeURIComponent 函数
例如：
{
foo: 'one one four',
bar: '五一四',
baz: 1919810
}
应该被编码为 bar=%E4%BA%94%E4%B8%80%E5%9B%9B&baz=1919810&foo=one%20one%20four。
向原始请求参数中添加 w_rid、wts 字段
将上一步得到的 w_rid 以及前面的 wts 追加到原始请求参数编码得到的 URL Query 后即可，目前看来无需对原始请求参数排序。
如前例最终得到 bar=514&foo=114&zab=1919810&w_rid=8f6f2b5b3d485fe1886cec6a0be8c5d4&wts=1702204169。
