Jquery 415不支持的媒体类型从$.ajax调用WCF服务
我试图从ASPX页面调用WCF web服务,如下所示:Jquery 415不支持的媒体类型从$.ajax调用WCF服务,jquery,asp.net,ajax,wcf,c#-4.0,Jquery,Asp.net,Ajax,Wcf,C# 4.0,我试图从ASPX页面调用WCF web服务,如下所示: var payload = { applicationKey: 40868578 }; $.ajax({ url: "/Services/AjaxSupportService.svc/ReNotify", type: "POST", data: JSON.stringify(payload), contentType: "application/json", dataType: "json"
var payload = {
applicationKey: 40868578
};
$.ajax({
url: "/Services/AjaxSupportService.svc/ReNotify",
type: "POST",
data: JSON.stringify(payload),
contentType: "application/json",
dataType: "json"
});
这样做会导致web服务器返回错误415不支持的媒体类型
。我确信这是WCF服务的配置问题,定义如下:
[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json)]
void ReNotify(int applicationKey);
web.config
文件中没有条目,因此假设服务使用默认配置。我不是这方面的专家,事实上我也有同样的问题(出于另一个原因)。但是,WCF服务似乎并不支持AJAX,因此您必须在web.config文件中包含以下代码才能启用它
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="NAMESPACE.AjaxAspNetAjaxBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
multipleSiteBindingsEnabled="true" />
<services>
<service name="NAMESPACE.SERVICECLASS">
<endpoint address="" behaviorConfiguration="NAMESPACE.AjaxAspNetAjaxBehavior"
binding="webHttpBinding" contract="NAMESPACE.SERVICECLASS" />
</service>
</services>
</system.serviceModel>
这是VS2012在我添加支持AJAX的WCF服务时生成的
