引子

最近根据业务的一些需求，所以放弃从快递鸟对接去电子面单，转而直接对接韵达开发平台：http://open.yundasys.com/ ，中间踩了一些坑，借此做了一个小案例给大伙，瞅瞅，若有需改进之处，还请指出！！！

废话不多数：首先咱先对韵达的一些接口参数了解清楚：

当然附上地址：http://open.yundasys.com/index.php?g=&m=ApiTools&a=exm

还有接口的一些SDK文件地址，这个就各位观众大老爷们自己去看了：http://open.yundasys.com/index.php?g=&m=ApiTools&a=apps&id=14

解决方案

上代码走起：基础参数的模型

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
　　//请求参数
    class RequestVO
    {
        /// <summary>
        /// XML数据内容
        /// </summary>
        public string xmldata { get; set; }
        /// <summary>
        /// 合作社区ID,由韵达给大客户提供
        /// </summary>
        public string partnerid { get; set; }
        /// <summary>
        /// 密码
        /// </summary>
        public string password { get; set; }
        /// <summary>
        /// 数据请求类型，如request=data；其中data表示下单，详细请见request字典表
        /// </summary>
        public string request { get; set; }
        /// <summary>
        /// 请求的版本,当前版本为1.0
        /// </summary>
        public string version { get; set; }
    }

要求

当前按照SDK的要求：

请求报文说明：

1. 数据传输以HTTP POST方式发送，数据字符集一律采用UTF-8

2. xmldata首先需要进行base64编码

3. validation的效验方式采用 MD5(xmldata + partnerid + 密码)，这里的加号为字符串连接符号。

4. 所有参数最终均须在完成数据转换后进行URL编码。

请求报文详细解释：

1.假设partnerid为YUNDA；密码为123456；xmldata内容为

<order></order>

2.xmldata经过base64编码以后变成PG9yZGVyPjwvb3JkZXI+

3.那么要签名的内容为PG9yZGVyPjwvb3JkZXI+YUNDA123456，经过md5后的内容就为f197e870a12528e38cb483b4e371f4ea

4.然后再对xmldata经过URL编码，得到字符串PG9yZGVyPjwvb3JkZXI%2B

5.同样需要对其他字段进行URL编码，否则可能会影响POST传递，具体请参见HTTP POST传输协议

6.最终要发送的数据为： partnerid=YUNDA&version=1.0&request=data&xmldata=PG9yZGVyPjwvb3JkZXI%2B&validation=f197e870a12528e38cb483b4e371f4ea
