     * 计算签名
     * S1: 先过滤掉 sign 和值为空的参数；
     * S2: 在将所有业务参数按照参数名进行升序排序；
     * S3: 以 `HTTP URL` 风格拼接成待签名的字符串，如：`a=1&b=2&c=123`
     * S4: 再将密钥以 `&app_secret=您的密钥` 形式拼接到上一步待签名的字符串后面，如：`a=1&b=2&c=123&app_secret=您的密钥`
     * S5: 使用标准 MD5 算法对上述字符串进行签名（忽略大小写）；
     * S6: 将其写入 `sign` 进行 `HTTP POST` 请求即可。
