对淘宝API sign签名老计算不对
代码如下:
using System;using System.Collections.Generic;using ponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Security.Cryptography;namespace WindowsFormsApplication1{public partial class Form1 : Form{public Form1(){InitializeComponent();}private void Form1_Load(object sender, EventArgs e){//正确的sign//http://gw./router/rest?sign=70950D9D8BEC7BF55BA572902733F261×tamp=-05-28+00%3A04%3A02&v=2.0&app_key=21792839&method=taobao.time.get&partner_id=top-apitools&format=jsonDictionary<string, string> param = new Dictionary<string, string>();param["app_key"] = "21792839";param["format"] = "json";param["method"] = "taobao.time.get";param["partner_id"] = "top-apitools";param["timestamp"] = "-05-28 00:04:02";param["v"] = "2.0";string secret = "c22cd49550a5fac8a775893a34a0391c";string x = getMD5String(param, secret);textBox1.Text = x;}public static String getMD5String(Dictionary<string, string> param, String str){String gets = getBeforeSign(param, str);Console.WriteLine(gets);MD5 md5 = new MD5CryptoServiceProvider();byte[] result = puteHash((new UTF8Encoding()).GetBytes(gets));//result = puteHash(result);return byteArrayToHexString(result);}private static String byteArrayToHexString(byte[] b){StringBuilder resultSb = new StringBuilder();string stmp;for (int i = 0; i < b.Length; i++){int md = (b[i] & 0XFF);stmp = "" + md.ToString("X"); ;if (stmp.Length == 1)resultSb.Append("0").Append(stmp);elseresultSb.Append(stmp);}return resultSb.ToString().ToUpper();}private static String getBeforeSign(Dictionary<String, String> param, String orgin){String indexs = orgin;if (param == null)return null;foreach (KeyValuePair<String, String> var in param){String name = (String)var.Key.ToString();orgin += name;orgin += param[name];}orgin = orgin + indexs;return orgin;}}}
运行结果:
848457EDB79276ACDC1B1E636CDC5757
正确结果:
70950D9D8BEC7BF55BA572902733F261
请问是什么问题?
