Common ashx calls

Directly Add code

There is still a certain degree of versatility

<% @ WebHandler Language = "C #" Class = "MyService" %> using System; using System. web; using System. collections. generic; // <summary> // test access path: http: // localhost: 2484/TestAjaxFrameWork/MyService. ashx?
