好多年没写java了,不过大致能明白要做什么,不保证代码是对的,你可以参考下


using System;
using System.Security.Cryptography;
using System.Text;
using System.Web;

public class DdConfigSign {
    public static string sign(string jsticket, string nonceStr, long timeStamp, string url) {
        string plain = "jsapi_ticket=" + jsticket + "&noncestr=" + nonceStr + "&timestamp=" + timeStamp
+ "&url=" + decodeUrl(url);
        try {
            //对字符串进行sha256加密,输出十六进制小写字符串
            byte[] hash = new SHA256Managed().ComputeHash(Encoding.UTF8.GetBytes(plain));
            return BitConverter.ToString(hash).Replace("-", "").ToLower();
        } catch (Exception e) {
            throw new Exception(e.ToString());
        }
    }
    /// <summary>
    /// 对url的query中的值进行urlDecode
    /// </summary> 
    private static string decodeUrl(string url) {
        string[] ss = url.Split('?');
        StringBuilder sb = new StringBuilder();
        sb.Append(ss[0]);
        sb.Append("?");
        foreach (var query in ss[1].Split('&')) {
            if (query.Length > 0 && query.Contains("=")) {
                string[] kv = query.Split('=');
                if (kv.Length == 2) {
                    sb.Append(kv[0] + "=" + HttpUtility.UrlDecode(kv[1], Encoding.UTF8));
                }
            }
        }
        return sb.ToString();
    }
    /// <summary>
    /// 获得指定长度的随机字符串
    /// </summary> 
    public static string getRandomStr(int count) {
        string baseStr = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
        StringBuilder sb = new StringBuilder();
        Random rd = new Random();
        for (int i = 0; i < count; i++) {
            sb.Append(baseStr[rd.Next(0, baseStr.Length)]);
        }
        return sb.ToString();
    }
}
