我有一个jquery用一个整数调用asp.net Web服务。
在移植到.net 4.0的旧版应用程序上,我无法使此调用正常工作。
我可以调用没有参数的方法,但是将数据发送到Web方法将返回以下错误:
System.InvalidOperationException: Request format is invalid: application/json; charset=UTF-8.
at System.Web.Services.Protocols.HttpServerProtocol.ReadParameters()
at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()
我在一个空白项目中创建了完全相同的代码,并且工作正常。我在web.config中看不到空白项目添加的任何内容,这会有所作为。
jQuery代码
$.ajax({
type: "POST",
url: "/WebService1.asmx/Test",
data: JSON.stringify({"code": 1234}),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
alert(msg);
}
});
我的网络服务代码
<ScriptService()> _
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ToolboxItem(False)> _
Public Class WebService1
Inherits WebService
<WebMethod()>
Public Function Test(ByVal code As Integer) As String
Return "success"
End Function
<WebMethod()>
Public Function Hello() As String
Return "hello"
End Function
End Class

最佳答案
DOH,我在错误的web.config中工作。
像许多关于SO的问题一样,解决方案是添加以下内容。
<system.webServer>
<handlers>
<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</handlers>
</system.webServer>
