京东快递上门揽件-在线下单API接口开发

前言

近几年来，我国电子商务交易规模越来越大，线上订单越来越多，退换货的情况也越来越常见。退换货环节是线上购物过程中的重要一环，也是体现电商平台与商家服务水平的重要方面。同时，退换货也是电商平台、商家与消费者之间最容易产生纠纷的环节。为了保障这个环节的服务，电商平台推出了退换货上门取件业务。退换货上门取件是为买家在退货时，提供的一种省心，便捷的物流服务，当买家购买的商品在申请换货或者发起维权投诉时需要退货，不需要自己邮寄商品，由物流公司安排快递员上门取件的一项服务。

8.分步讲解（C#版本）
请求数据包结构
京东快递上门揽件-在线下单API接口开发

9 .签名说明
关于签名
快递鸟和第三方电子商务公司系统进行对接，有一定的安全机制。采用IP认证加签名的方式对接，具体方案如下：

1.防止数据被篡改

在POST请求中会传递5个必须(R)参数
RequestData==数据内容(URL编码:UTF-8)
EBusinessID==用户ID
RequestType=请求指令类型
DataSign== 数据内容签名：把(请求内容(未编码)+ApiKey)进行MD5加密，然后Base64编码，最后进行URL(utf-8)编码
DataType==2(返回数据类型为json)
注：
DataSign生成后，对方接收到数据后，以同样的算法进行签名(推送接口RequestType为101/102不需要进行URL编码)，生成摘要，对比两者的摘要是否相同，如果不同，说明传递过程中发生数据篡改。

2.调用接口的身份认证
注册成为快递鸟用户后，会生成对应的用户ID和APIKey，用户ID相当于用户名，APIKey相当于密码。
举例：
1.假设
RequestData (JSON)内容为：
{'OrderCode':'','ShipperCode':'SF','LogisticCode':'118954907573'}

经过URL(UTF-8)编码的内容为：
%7b%27OrderCode%27%3a%27%27%2c%27ShipperCode%27%3a%27SF%27%2c%27LogisticCode%27%3a%27118954907573%27%7d；
EBusinessID=1237100【示例ID，不可用来实际使用】
APIKey=56da2cf8-c8a2-44b2-b6fa-476cd7d1ba17【示例Key，不可用来实际使用】

2.那么DataSign签名的内容为
{'OrderCode':'','ShipperCode':'SF','LogisticCode':'118954907573'}56da2cf8-c8a2-44b2-b6fa-476cd7d1ba17
经过md5和base64后的内容就为：OWFhM2I5N2ViM2U2MGRkMjc4YzU2NmVlZWI3ZDk0MmE=，
在经过URL(UTF-8)编码的内容为：OWFhM2I5N2ViM2U2MGRkMjc4YzU2NmVlZWI3ZDk0MmE%3d
最终要发送的数据为：
RequestType=1002&EBusinessID=1237100&RequestData =%7b%27OrderCode%27%3a%27%27%2c%27ShipperCode%27%3a%27SF%27%2c%27LogisticCode%27%3a%27118954907573%27%7d&DataSign=OWFhM2I5N2ViM2U2MGRkMjc4YzU2NmVlZWI3ZDk0MmE%3d&DataType=2

3.接收方收到数据后，获得
EBusinessID 和RequestData和DataSign等这几个数据。
4.接收方对EBusinessID 得到APIKey，RequestData+APIKey的数据进行
md5和base64后的内容就为
OWFhM2I5N2ViM2U2MGRkMjc4YzU2NmVlZWI3ZDk0MmE=

5.接收方判断签名后的数据跟传递过来的DataSign是否一致，如果一致进行业务操作，如果不一致返回错误。

//加密私钥，由快递鸟提供
string keyValue = "56da2cf8-c8a2-44b2-b6fa-476cd7d1ba17";//仅作为示例Key，不可用来实际使用

string jsonStr = "json请求报文";
//把(jsonStr+APIKey)进行MD5加密，然后Base64编码，最后 进行URL(utf-8)编码
datasign = HttpUtility.UrlEncode(base64(MD5(jsonStr + keyValue, "UTF-8"), "UTF-8"), Encoding.UTF8);
//请求报文参数
string PostStr = "RequestType=1002&EBusinessID= used &RequestData=jsonStr &DataSign= datasign&DataType=DataType";
