筆記一下 jQuery AJAX 傳遞 JSON 到 ASP.Net 的方式

 

拿工作上的例子來 demo 好了

=======================================

SuncolorFBLogin.aspx

javascript : 

FB.api('/me', function (response) {

var member = {member: {

"uid": response.id,

"cname": response.name,

"email": response.email,

"birthday": response.birthday,

"gender": response.gender

}};

$.ajax({

url: "SuncolorFBLogin.aspx/FBMemberCheck",

type: "POST",

contentType: "application/json; charset=utf-8",

data: JSON.stringify(member),

dateType: "json",

success: function (res) {

document.write(res.d.uid);

}, error: function (err) {

alert(err.responseText);

}

});

});

SuncolorFBLogin.aspx.vb

ASP.Net (因為是老專案所以用VB.Net,用C#自己轉應該也還好)

Imports System.Web.Services

Imports System.Web.Script.Services

Imports Newtonsoft.Json

Imports Newtonsoft.Json.Linq

Imports System.Web.Script.Serialization

<WebMethod()> _

Public Shared Function FBMemberCheck(ByVal member As member) As member

'可以直接 member.uid 取值

'如果要還原成JSON字串就用下面這樣

Dim objSerializer As JavaScriptSerializer = New JavaScriptSerializer()

Dim json As String = objSerializer.Serialize(member)

'如果要把JSON字串反序列化再傳出去就用下面這樣

Dim obj As JavaScriptSerializer = New JavaScriptSerializer()

Return obj.Deserialize(Of member)(json)

End Function

 

Public Class member

Dim _uid As String = ""

Dim _cname As String = ""

Dim _email As String = ""

Dim _birthday As String = ""

Dim _gender As String = ""

Public Property uid() As String

Get

Return _uid

End Get

Set(ByVal value As String)

_uid = value

End Set

End Property

Public Property cname() As String

Get

Return _cname

End Get

Set(ByVal value As String)

_cname = value

End Set

End Property

Public Property email() As String

Get

Return _email

End Get

Set(ByVal value As String)

_email = value

End Set

End Property

Public Property birthday() As String

Get

Return _birthday

End Get

Set(ByVal value As String)

_birthday = value

End Set

End Property

Public Property gender() As String

Get

Return _gender

End Get

Set(ByVal value As String)

_gender = value

End Set

End Property

End Class
