请求加密及示例

加密步骤：

签名说明及实例
1 假设用户apisecret为78FBB3D68B40A347644619ACF902CED3，请求入参如下：

{
    "apiKey" : "test1",
    "timestamp" : '20171211103331',
    "data" :
    {
        "lineId" : "10194",
        "entityId" : "329620"
    }
}

2 首先，我们要按照key值首字母排序，并去掉value为空的，得到以下参数：

{
    "apiKey" : "test1",
    "data" :
    {
        "lineId" : "10194",
        "entityId" : "329620"
    },
    "timestamp" : "20171211103331",
}

3 将参数名、参数值依次拼接在一起：

 apiKey=test1&data={"lineId":"10194","entityId":"329620"}&timestamp=20171211103331

4 在开头加上apisecret:

78FBB3D68B40A347644619ACF902CED3&apiKey=test1&data={"lineId":"10194","entityId":"329620"}&timestamp=20171211103331

5 进行MD5加密，并将结果全部转为大写，获得签名值：

A07176FF3A27658457444708C0CE59DF

6 签名生成结束，请求入参变为：

{
    "apiKey" : "test1",
    "apisecret" : "78FBB3D68B40A347644619ACF902CED3",
    "currentTimeStamp" : "20171211103331",
    "sign" : "A07176FF3A27658457444708C0CE59DF",
    "uri" : "http://xxx.com/tours/productdetail",
    "data" :
    {
        "lineId" : "10194",
        "entityId" : "329620"
    }
}

C# Demo：

.net版生成签名工具类

using System.Collections.Generic;
using System.Security.Cryptography;
using System.Text;
namespace ConsoleApplication1
{
    public class Signature
    {
        public string GetSign(IDictionary<string, string> parameters, string secret)
        {
            // 第一步：把字典按Key的字母顺序排序
            IDictionary<string, string> sortedParams = new SortedDictionary<string, string>(parameters);
            IEnumerator<KeyValuePair<string, string>> dem = sortedParams.GetEnumerator();
            // 第二步：把所有参数名和参数值串在一起
            StringBuilder query = new StringBuilder(secret);
            while (dem.MoveNext())
            {
                string key = dem.Current.Key;
                string value = dem.Current.Value;
                if (!string.IsNullOrEmpty(key))// && !string.IsNullOrEmpty(value) 空值也加入计算！！
                {
                    query.Append(key).Append(value);
                }
            }            
            // 第三步：使用MD5加密
            MD5 md5 = MD5.Create();
            byte[] bytes = md5.ComputeHash(Encoding.UTF8.GetBytes(query.ToString()));
            // 第四步：把二进制转化为大写的十六进制
            StringBuilder result = new StringBuilder();
            for (int i = 0; i < bytes.Length; i++)
            {
                result.Append(bytes[i].ToString("X2"));
            }
            return result.ToString();
        }
    }
}
 class Program
 {
        public static void Main(string[] args)
        {
            string apiKey = "test1";
            string timestamp = DateTime.Now.ToString("yyyyMMddHHmmss");
            string data = "\"lineId\":\"10194\",\"entityId\":\"329620\"";
            string version = "1";
            string secret = "78FBB3D68B40A347644619ACF902CED3";
            IDictionary<string, string> parameters = new Dictionary<string, string>();
            parameters.Add("apiKey", apiKey);
            parameters.Add("timestamp", timestamp);
            parameters.Add("version", version);
            parameters.Add("data", data);
            Signature sign = new Signature();
            string resultSign = sign.GetSign(parameters, secret);
            Console.WriteLine(resultSign);
        }
}

PHP Demo：

   /**
     *    创建签名
     */
    function create_sign($data,$timestamp){
        $sign['apiKey']="you apiKey";
        $sign['version']="v1";
        $sign['data']=json_encode($data);
        $sign['timestamp']=$timestamp;
        ksort($sign);
        $signstr="you secreet";
        foreach($sign as $k=>$v){
            $signstr.=$k.$v;
        }
        return mb_strtoupper(md5($signstr));
    }
    /**
     *    通用请求方法
     */
    function query($postdata,$url){
        // 时间戳
        $t=date('YmdHis');
        // 调用签名方法
        $sign=$this->create_sign($postdata,$t);
        $pd=[
            'apiKey'=>"you apiKey",
            'version'=>"v1",
            'data'=>json_encode($postdata),
            'timestamp'=>$t,
            'sign'=>$sign
        ];
        // curl方法请求。具体方法请自行撰写
        $curldata =curl($url,json_encode($pd));
    }
