[C #] WebService using JSON format to pass the pen + JQuery test

0 2

Because of some factors, it is necessary to change the webservice, very traditional, but a lot of companies are still in use.

Because of the relationship between XML and not wanting him to pass the material, I had to try to clean up the JSON.

So I started my journey to rewrite.

First of all, there are a lot of files on the Internet, maybe because of the different situation, I have been confused many times by many tests.

Finally, we find the answer. Take a moment to remember.

0 2

First I started with three different WebMethod to test three different outputs.

0 2

getuserinfostring– Get string

Getoneuserinfo-Get an object

Getusers-Get the objects

0 2

Using System.Collections.Generic;Using System.Web. Script.services;Using System.Web. Services;Namespace jsonservicesample{PublicClass User {PublicString Name {get; set;}Publicint age {get; set;}} [WebService (Namespace ="", Description ="For Donma Test")] [System.ComponentModel.ToolboxItem (False)] [ScriptService]PublicClassService1:webservice {[WebMethod] [Scriptmethod (Responseformat = Responseformat.Json)]PublicString Getuserinfostring (String name,int age) {Return name +"," + age; } [WebMethod] [Scriptmethod (Responseformat = Responseformat.Json)]Public User Getoneuserinfo (string name, int.) { return (new User {name = name, age = Age}); [WebMethod] [Scriptmethod (Responseformat = Responseformat.  Json)] public user[] Getusers (string name, Int. age) {list<user> res = new list<user> (); Res. ADD (new User {name = name + "1", age = Age}); Res. ADD (new User {name = name + "2", age = Age}); return Res. ToArray (); } }}

If this 0 2 [C #] Web Service removes xmlns 0 2 I'll first remove the XML namespace

One more point, and I'll add it on top of each method.

[WebMethod] [Scriptmethod (Responseformat = Responseformat.  Json)]

Because sometimes I need to use get to pass the pass so I'm adding it in Web Config

In System. Join in the Web

Strange why not JSON , don't be nervous ... We continue to use JQuery to call and see.

JQuery Code:

<typeIDvalue<type= "Text/javascript">     

   2:        function GetInfo () {

   3:            var $res;

   4:            $.ajax ({

   5:                "POST",

   6:                "Service1.asmx/getoneuserinfo",

   7:                "application/json; Charset=utf-8 ",

   8:                false,

   9:                false,

  Ten:                'json',

  One:                "{name: ' When hemp ', age:29}",

  :                Function (data) {

  :                    if (Data.hasownproperty ("D")) { 

  :                        $res = DATA.D;

  :                    }

  :                    Else

  :                        $res = data;

  :                }

  :            });

  :            return $res;

  :        }

  22:        

  :        $ (' #ipt1 '). Click (function () { 

  :            var res = GetInfo ();

  :            alert (res. Name);

  :        });

  28:        

  29:    

</Script>

Press the button down and I'll have him call Getoneuserinfo this method.

and use Post

Look at the results.

nn. is JSON, but one more D 0 2 with __type basically 0 2 __type do not move he does not affect, but 0 2 D this thing must be handled.

So I'll take this article: http://encosia.com/never-worry-about-asp-net-ajaxs-d-again/

Change to write. The three different values of the above are measured. All ok~~

This will not affect the traditional WebService Reference call 0 2 WebService.

You can also pass through the JSONthrough the jquery call ...

Take a moment to remember. To the people in need ...
