在url重写或url映射后，Jquery ajax不调用webmethod [英] Jquery ajax not calling webmethod after url rewriting or url mapping
问题描述
500 内部服务器错误
jQuery Ajax在url重写后没有调用webmethod
WebService.asmx
包含以下colde
[WebMethod]
公共字符串HelloWorld（）{
返回Hello World;
}
-------------我的jquery代码-------------
< pre lang =JavaScript>< script type = text / javascript>
$（ document ）。ready（ function （）
{
$ .ajax（{
type： POST，
url：' WebService.asmx / HelloWorld'，
data：{}，
contentType： application / json; charset = utf-8，
成功：countItem
}）;
function countItem（data，status，xhr）
{
alert （data.d）;
}
}）;
< / script>
它运行正常，但是当我使用url重写或url生根时给出错误
原始路径
http：// localhost：1388 / WebSite15 / WebService.asmx / HelloWorld
它会工作
但是在url重写或url rooting之后
http：// localhost：1388 / WebSite15 / Products / WebService.asmx / HelloWorld
所以它给出了错误
我尝试了什么：
void Application_Start（object sender，EventArgs e）
{
//在应用程序启动时运行的代码
//在应用程序启动时运行的代码
RegisterRoute（System.Web.Routing.RouteTable.Routes）;
}
void RegisterRoute（System.Web.Routing.RouteCollection路线）
{
routes.Add（Pr产品，新的System.Web.Routing.Route（{Products} / {category}，新的CategoryRouteHandler（）））;
}
公共类CategoryRouteHandler：IRouteHandler
{
public CategoryRouteHandler（）{}
public IHttpHandler GetHttpHandler（RequestContext requestContext）
{
// AdventureWorksEntities awe = new AdventureWorksEntities（）;
string cat = requestContext.RouteData.Values [category] as string;
string pageval = requestContext.RouteData.Values [Products] as string;
// int catid = awe.ProductCategories.Where（x => x.Name == cat）.FirstOrDefault（）。ProductCategoryID;
HttpContext.Current.Items [catid] = cat;
if（pageval.ToLower（） .ToString（）。Trim（）==test）
{
返回BuildManager.CreateInstanceFromVirtualPath（〜/ test1.aspx ，typeof（Page））as Page;
}
else
{
返回BuildManager.CreateInstanceFromVirtualPath（ 〜/ Products.aspx，typeof（Page））为Page;
}
// string vartualpath = BuildManager.CreateInstanceFromVirtualPath（ 〜/ Products.aspx，typeof（Page））。ToString（）;
//将BuildManager.CreateInstanceFromVirtualPath（〜/ category.aspx，typeof（Page））返回为Page;
}
}
（ document ）.ready（ function （）
{
type： POST，
url： ' WebService.asmx / HelloWorld'，

您好，
来自您的javascript代码我感觉到的是当你重写或映射时，url被更改并且不提供相同的url i在ajax网址。
你的网址：
' WebService.asmx / HelloWorld'
但是在映射为url更改后，ajax找不到相同的。
所以，我认为你在ajax中的网址应该是：
' / Products / WebService.asmx / HelloWorld'
注意：请在URL的开头加上一个/，以便在调用不同控制器的方法时能够正确路由。
请尝试发布查询（如果有的话）。
谢谢，

Hi,
From your javascript code what I sense is While you are rewriting or mapping , the url is changed and the same url is not supplied in the ajax url.
your url:'WebService.asmx/HelloWorld'
but after mapping as the url is changed, ajax is unable to find the same.
So, I think your url in ajax should be:
'/Products/WebService.asmx/HelloWorld'
Note: please put a "/" in the beginning of the url sothat it will be able route properly when a method of a different controller is called.
Please try and post queries if any.
Thanks,
Prateek
