Alipay interface (just finished, should be the best of the present)

Interface

Alipay's interface call is very inconvenient, just do a package, realize the virtual transaction and physical transactions.
There are three projects in the solution as well as NDoc generated documents, simple sequence diagrams: Commonalipay, encapsulated Alipay interface.
Testali,asp.net's Test project
Testcommonalipay,nunit's Test project.
Call Method:
1. Introduction of CommonAliPay.dll
2, the implementation of Alipay service interface method call Way:
AliPay ap = new AliPay ();
string key = "";//fill in your key
String partner = "";/fill in your own partner
StandardGoods bp = new StandardGoods ("Trade_create_by_buyer", partner, Key, "MD5", "Card 2", Guid.NewGuid (). ToString (), 2.551m, 1, "hao_ding2000@yahoo.com.cn", "hao_ding2000@yahoo.com.cn"
, "EMS", 25.00m, "Buyer_pay", "1");
Bp. Notify_url = "http://203.86.79.185/ali/notify.aspx";
Ap. Createstandardtrade ("Https://www.alipay.com/cooperate/gateway.do", BP, this); The above is the universal calling method.
The following are the only ways to support virtual goods:
string key = "";//fill in your key
String partner = "";/fill in your own partner
AliPay ap = new AliPay ();
Digitalgoods bp = new Digitalgoods ("Create_digital_goods_trade_p", partner, Key, "MD5", "Card 2", Guid.NewGuid (). ToString (), 2.551m, 1, "hao_ding2000@yahoo.com.cn", "hao_ding2000@yahoo.com.cn");
Bp. Notify_url = "http://203.86.79.185/ali/notify.aspx";
Ap. Createdigitaltrade ("Https://www.alipay.com/cooperate/gateway.do", BP, this); 3, the implementation of Alipay notification interface method calls (support virtual and in-kind):
protected void Page_Load (object sender, EventArgs e)
{

string key = "";//fill in your key
String partner = "";/fill in your own partner
AliPay ap = new AliPay ();
String Notifyid = request.form["notify_id"];
Verify v = new Verify ("Notify_verify", partner, Notifyid);
Ap. Waitsellersendgoods+=new Alipay.processnotifyeventhandler (ap_waitsellersendgoods);
Ap. Waitbuyerpay + = new Alipay.processnotifyeventhandler (Ap_waitbuyerpay);
Ap. Processnotify (This, "https://www.alipay.com/cooperate/gateway.do", Key,v, "utf-8");
}

void Ap_waitbuyerpay (object sender, Notifyeventargs e)
{
Add your own processing logic
Log4net.log.Error ("Wait buyer pay fire");
}

  
    private void Ap_waitsellersendgoods (object sender, Notifyeventargs e)
    {
       //Add your own processing logic
         Log4net.log.Error ("Waitsellersendgoods Fire"); The transaction status of the
   } Alipay is defined as an event of similar name.
Partial source code resolution:
1, parse Forms collection to the Notifyeventargs class, because the data for this class is used to do md5sign, so all value types cannot have initial values, such as 0 of Int. So use the nullable model.
   Private Notifyeventargs parsenotify (NameValueCollection NV, object obj)
         {
            propertyinfo[] Propertyinfos = obj. GetType (). GetProperties (BindingFlags.Public | BindingFlags.Instance);

foreach (PropertyInfo pi in Propertyinfos)
{
String v = NV. Get (pi. Name.tolower ());
if (v!= null)
{
if (pi. PropertyType = = typeof (String)
{

Pi. SetValue (obj, V, null);

                    }
                     else if (pi. PropertyType = = typeof (int?))
                     {
                         Pi. SetValue (obj, int. Parse (v), NULL);
                    }
                     else if (pi. PropertyType = = typeof (decimal))
                     {

                         Pi. SetValue (obj, decimal. Parse (v), NULL);
                    }
                     else if (pi. PropertyType = = typeof (DateTime))
                     {

Pi. SetValue (obj, DateTime.Parse (v), NULL);
}
else if (pi. PropertyType = = typeof (bool))
{

Pi. SetValue (obj, bool. Parse (v), NULL);
}
Else
{
Transformation failure throws an exception
Pi. SetValue (obj, V, null);
}
}

}
Return (Notifyeventargs) obj;

}
2. Get sorted parameters from type
/**////<summary>
Get the sorted parameters
</summary>
<param name= "obj" ></param>
<returns></returns>
Private sortedlist<string,string> GetParam (object obj)
{

propertyinfo[] Propertyinfos = obj. GetType (). GetProperties (bindingflags.public| BindingFlags.Instance);
sortedlist<string, string> sortedlist = new sortedlist<string, string> ( Stringcomparer.currentcultureignorecase);
foreach (PropertyInfo pi in Propertyinfos)
{

if (pi. GetValue (obj, null)!= null)
{
if (pi. Name = = "Sign" | | Pi. Name = = "Sign_type")
{
Continue
}
Sortedlist.add (pi. Name.tolower (), Pi. GetValue (obj, null). ToString ());

}
}
return sortedlist;

}3, generating parameters from SortedList
private String Geturlparam (sortedlist<string, string> sortedlist,bool isencode)
{
StringBuilder param = new StringBuilder ();
StringBuilder Encodeparam = new StringBuilder ();
if (Isencode = = False)
{

foreach (keyvaluepair<string, string> kvp in SortedList)
{
String t = String. Format (' {0}={1} ', kvp. Key, kvp. Value);
Param. Append (t + "&");
}
return param. ToString (). TrimEnd (' & ');
}
Else
{
foreach (keyvaluepair<string, string> kvp in SortedList)
{
String et = string. Format ("{0}={1}", Httputility.urlencode (KVP). Key), Httputility.urlencode (kvp. Value));
Encodeparam.append (et + "&");
}
Return encodeparam.tostring (). TrimEnd (' & ');
}

}
