从jQuery调用ASP.NET ASMX Web服务
问题描述:
我想从使用JSON的jQuery调用ASMX并获得SOAP错误响应。从jQuery调用ASP.NET ASMX Web服务
我在做什么错?
这是我的jQuery的电话:
$.ajax({
type: "POST",
url: '/Services/TeamPerson.asmx',
contentType: "application/json; charset=utf-8",
data: {'active':false, 'team_id':team_id, 'player_id':player_id},
dataType: "json",
success: function(msg) {
alert(msg);
},
error: function(xhr, msg) { alert(msg + '\n' + xhr.responseText); }
});
这是我的web服务:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
[ScriptService]
public class TeamPerson : WebService
{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void SetPlayerStatus(bool active, ulong team_id, ulong player_id)
{
// blah blah
}
}
我得到一个讨厌的SOAP错误回:
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

我可以通过打/Services/TeamPerson.asmx
我的浏览器和Web方法工作正常。我还在web.config中定义了以下内容:
<httpHandlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/>
<add verb="GET,HEAD,POST" path="TinyMCEHandler.aspx" type="Moxiecode.TinyMCE.Web.HttpHandler,Moxiecode.TinyMCE" />
</httpHandlers>
<httpModules>
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</httpModules>
答
您没有定义在服务上调用哪个方法。尝试更改您的JQuery行url: '/Services/TeamPerson.asmx',
到url: '/Services/TeamPerson.asmx/SetPlayerStatus',
答
也许这是在URL中缺少的Web方法以及参数。
var teamID = 123;
var playerID = 456;
var active = true;
var webMethod = 'http://foo.net/TeamPerson.asmx/SetPlayerStatus'
var parameters = "{'active':'" + active +
"','team_id':'" + teamID +
"','player_id':'" + playerID + "'}"
$.ajax({
type: "POST",
url: webMethod,
data: parameters,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
alert('all good');
},
error: function(e){
alert('err');
}
});

它的旧,我知道,但....为什么你不使用JSON.stringify(参数)在“数据”参数? – 2016-12-16 15:06:56
这有很大的区别,谢谢!现在我只是得到这个错误:{“消息”:“无效的JSON原语:活跃。”,“StackTrace”:“在...... 我是否传递错误的数据{} params? – 2010-08-17 20:57:06
啊!我didn数据:“{'active':'false','team_id':”+ team_id +“,'player_id':”+ player_id +“}”,这样的数据需要被引用的字符串参数: – 2010-08-17 21:02:37
