Question

这是我的编号:


var DTO = { " productCategoryId ": " 10 " };
$.ajax({
 type: "GET",
 url: "/WebService/DsmWebServices.asmx/GetProductSubCategory",
 data: DTO,
 contentType: "application/json; charset=utf-8",
 dataType: "json",
 success: function (msg) {
  window.alert("success");
 },
 error: function (msg) {
 }
});

这是我的网络服务方法:


[WebMethod,ScriptMethod(UseHttpGet=true)]
public bool GetProductSubCategory(int productCategoryId)
{
 //do some stuff
 return true;
}

问题是, j功能因以下错误而失效:


{"Message":"Invalid web service call, missing value for parameter:
u0027productCategoryIdu0027.","StackTrace":"   at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)
   at
System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)
   at
System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)
   at
System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

通过使用火力,请求的URL jQuery


http://192.168.1.100:8888/WebService/DsmWebServices.asmx/GetProductSubCategory?%27productCategoryId%27=%2710%27

你们必须用“职位”来形容你的神职。此外,提供给你的网络服务机构的数据需要是一种 j笑。无 j子物体。探讨json2图书馆的强化方法:
