我正在尝试构建一个jquery插件，它使用AJAX POST请求命中VB.NET Web服务。现在我想站出发送JSON的请求然后在console.log中接收它。我有它工作然后我改变了命名约定我现在不断收到404错误。我已经发布了整个web.config文件，以防万一。只需将数据发送到Web服务，然后将相同的数据返回到控制台。到目前为止，这是我的代码：
JS：
(function($){
$.fn.loadMGMT = function(options) {
$this = $(this);
data = $.extend({
level: 'ORA',
titles: 'Administrator'
}, options );
$.ajax({
type: 'POST',
cache: false,
headers: { 'Access-Control-Allow-Origin': '*' },
url: '/webapps/webservices/Intranet/getActiveDirectoryInfo.aspx/leadership',
data: "{leader:" + JSON.stringify(data) + "}",
contentType: 'application/json; charset=utf-8',
dataType: 'json',
}).done(function(api){
console.log(api);
});
};
}(jQuery));
$(document).ready(function(e) {
$('#leaders').loadMGMT({
level: "DORA",
titles: 'Regional Administrator'
});
});
网络服务：
Imports System.Collections.Generic
Partial Class VB
Inherits System.Web.UI.Page
<System.Web.Services.WebMethod()> _
Public Shared Function leadership(ByVal leader As Leader) As Leader
Return leader
End Function
End Class
Public Class Leader
Private _level As String
Public Property Name As String
Get
Return _level
End Get
Set(ByVal value As String)
_level = value
End Set
End Property
Private _titles As String
Public Property Name As String
Get
Return _titles
End Get
Set(ByVal value As String)
_titles = value
End Set
End Property
End Class

尝试以下操作，这些天找人使用VB并不容易！
我的代码也处理CORS问题，html可以托管在www.a.com（或作为Android或iphone中的本机应用程序），Web服务可以托管在www.b.com
使用适用于Apache Cordova CTP3.1的工具在VS 2015社区或VS 2013社区更新4中创建空白解决方案
在解决方案中创建一个空白的JavaScript Cordova项目。
使用以下代码替换index.html：
<html> <head> <script type="text/javascript"> function funCheckWS() { var tblLogin = {}; tblLogin.ReturnCode = "0000"; jQuery.support.cors = true; $.ajax({ type: 'POST', url: 'http://localhost:8080/wsMain.asmx/funCheckWS', data: "{tblLogin:" + JSON.stringify(tblLogin) + "}", contentType: 'application/json; charset=utf-8', dataType: 'json', crossDomain: true, async: false, success: function (r) { tblLogin.ReturnCode = r.d.ReturnCode; alert("Return Code from Web Services:" + tblLogin.ReturnCode); }, error: function (xhr, ajaxOptions, thrownError) { // Browser does not support WS //alert(xhr.status); //alert(thrownError); } }); } </script> </head> <body> </body> </html>
创建一个Visual Basic＆＃34; Asp.Net Web应用程序＆＃34;，以下内容涉及此项目：
在Web.config中，在
<webServices> <protocols> <add name="HttpGet"/> <add name="HttpPost"/> </protocols> </webServices>
<httpProtocol> <customHeaders> <add name="Access-Control-Allow-Methods" value="POST,OPTIONS,GET"/> <add name="Access-Control-Allow-Headers" value="Cache-Control, Pragma, Origin, Authorization, Content-Type, X-Requested-With,Accept"/> <add name="Access-Control-Allow-Origin" value="*"/> </customHeaders> </httpProtocol>
Public Class tabLogin Private _ReturnCode As String Public Property ReturnCode As String Get Return _ReturnCode End Get Set(ByVal value As String) _ReturnCode = value End Set End Property End Class
Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.ComponentModel Imports System.Web.Script.Serialization Imports System.Web.Script.Services Imports System Imports System.Collections.Generic Imports System.Linq Imports System.Web <System.Web.Script.Services.ScriptService()> _ <System.Web.Services.WebService(Namespace:="http://tempuri.org/")> _ <System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _ <ToolboxItem(False)> _ Public Class wsMain Inherits System.Web.Services.WebService Private tblLogin As tabLogin <WebMethod()> _ <ScriptMethod(ResponseFormat:=ResponseFormat.Json)> _ Public Function funCheckWS(tblLogin As tabLogin) As tabLogin tblLogin.ReturnCode = "0001" Return tblLogin End Function End Class
构建此项目并使用IIS使用端口8080托管它。
构建javascript cordova项目并将其部署到手机或使用您喜欢的任何端口在IIS中托管index.html，例如8070。
在手机中，运行应用程序。或者在任何桌面浏览器中，使用http://localhost:8070/index.html
然后会出现一个消息框，其中包含ReturnCode =＆＃34; 0001＆＃34;，它是从Web服务返回的。
