我试图使用JSON从jQuery调用ASMX并获得SOAP错误响应。
我做错了什么?!
这是我的jQuery调用:
$.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); }
});
这是我的网络服务:
[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
}
}
我收到了一个讨厌的SOAP错误:
<?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">

我可以通过浏览器点击/Services/TeamPerson.asmx
并且网络方法正常。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"/>

答案 0 :(得分:15)
您没有定义在服务上调用哪种方法。尝试将您的JQuery行url: '/Services/TeamPerson.asmx',
更改为url: '/Services/TeamPerson.asmx/SetPlayerStatus',
答案 1 :(得分:5)
也许这是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');
}
});
