之前用快递100接口，但是快递100老是封IP没办法去上快递鸟的接口。看了下快递鸟的一个JSON的案例，但是发现里面还有一个MD5的加密。这个MD5加密应该怎么做啊。。。

JSON 范例

 string userID = "1109259";

 string keyValue = "56da2cf8-c8a2-44b2-b6fa-476cd7d1ba17";//加密私钥，由发货通提供

 string url = "http://api.kdniao.cc/Ebusiness/EbusinessOrderHandle.aspx";  //请求地址

 string DataType = "2"; 2-json

 string charset="UTF-8";//字符编码采用UTF-8

string js; // JSON字符串string

datasign = HttpUtility.UrlEncode(base64( MD5(jsonStr+keyValue, "UTF-8"),"UTF-8"),Encoding.UTF8);//把(jsonStr+AppKey)进行MD5加密，然后Base64编码，最后进行URL(utf-8)编码

string PostStr = "RequestType=1002&EBusinessID= userID &RequestData=jsonStr &DataSign= datasign&DataType=DataType"; //请求报文参数

string post = this.DoPost(url, PostStr);// 通讯协议使用Http协议Post请求方式

甜老师，这段代码是显示快递实时信息的我应该怎么加入到Textbox1中。尝试了好几种方法都不可行。。。

1、获取的信息正确了吗？msgbox弹出什么？

msgbox("物流状态:" & kdzt & " | 快递类型: " & kdlx & " | 运单号: " & ydh & " | 查询是否成功: " & sfcg & " | 失败原因: " & sbyy)

2、这样写

e.Form.Controls("Textbox1").text = vbcrlf & "物流状态:" & kdzt & " | 快递类型: " & kdlx & " | 运单号: " & ydh & " | 查询是否成功: " & sfcg & " | 失败原因: " & sbyy

甜老师这段代码倒没有问题，不过就是下面这段显示物流信息的我应该怎么加进去显示在vbcrlf & "物流状态:" & kdzt & " | 快递类型: " & kdlx & " | 运单号: " & ydh & " | 查询是否成功: " & sfcg & " | 失败原因: " & sbyy  下面

For Each jt As JToken In jo("Traces")
Output.Show( jt("AcceptTime").ToString & " | " & jt("AcceptStation").ToString )  
Next

For Each jt As JToken In jo("Traces")

    e.Form.Controls("Textbox1").text = vbcrlf & jt("AcceptTime").ToString & " | " & jt("AcceptStation").ToString
Next
