Standard WebService calls

Modern definitions of webservice generally tend to be restfull-style HTTP requests, but they still encounter the time code written by their predecessors.

We prefer to encapsulate the code to invoke instead of the service reference. Please see:

Annotations for Service.asmx Services

NET AJAX, uncomment the following line. 5     //[System.Web.Script.Services.ScriptService]6      Public classService:System.Web.Services.WebService7{}

The above can not be verified.

Client Invoke Tool

The request method (which removes the namespace of the service returned by the server) is submitted as a post

Server-Side Definition interface

Failure (98, E.message) astransexceldto; -             } -}

Call for example, note the following key = data, even if the parameters of the interface

1Transexceldto request =NewTransexceldto () {SessionId =Cache.sessionid};2 3 4 varPostData =Newdictionary<string,string>();5Postdata.add ("Data", common.utilities.serialize<transexceldto>(Request));6 7Transexceldto result = common.utilities.post<transexceldto> (Metadata.webserviceurl +"/importtransexcel", PostData);
