访问时命名的路由直接访问操作时没有发现,却发现我有一个名为路线:通过AJAX
routes.MapRoute(
name: "OfficeByZipCode",
url: "RetrieveOffice/ZipCode/{zipcode}",
defaults: new { controller = "RLO", action = "RetrieveOfficeByZipCode" }
);
我检索动作中的指定路线:
public ActionResult RetrieveByZipCode(string zipCode)
{
try
{
Office obj = null;
string urlOffice;
//build a route dictionary that includes the zip code
RouteValueDictionary route = new RouteValueDictionary
{
{"zipcode", zipCode}
};
//build the relative path for the route to retrieve JSON data
VirtualPathData vpd = RouteTable.Routes.GetVirtualPath(null, "OfficeByZipCode", route);
//combine the relative path with the site's root path
//use the config value rather than HttpContext.Current.Request.Url to overcome issues that arise from Load Balancers and SSL offloading
urlOffice = String.Concat(Properties.Settings.Default.RootUrl, vpd.VirtualPath);
//the rest of the code. not important for this example
现在,我访问这个动作在以下两种方法之一:
一,通过AJAX,从不同的页面:
$.ajax({
url: "Test/RetrieveByZipCode",
type: "POST",
data: JSON.stringify(formData),
dataType: "html",
contentType: "application/json; charset=utf-8",
success: function (data) {
$("#content").html(data);
},
error: function (error) {
alert("Error");
}
});
二,通过浏览器直接:
http://localhost/RLOService/test/RetrieveByZipCode/92677
当访问直接的动作,此行回来空:
VirtualPathData vpd = RouteTable.Routes.GetVirtualPath(null, "OfficeByZipCode", route);
但是,要求通过AJAX同样的动作,当它工作得很好。
两者之间的明显区别是我正在通过POST(AJAX)访问,另一个通过GET(URL)访问。如果我将AJAX操作更改为GET,则会收到相同的错误。为什么这会有所作为?
它期待一个网址为http://host..../RetrieveOffice/ZipCode/ {}邮政编码和你的直接URL犯规匹配用它 – HaBo 2014-08-28 20:07:16
@HaBo:我不确定你的意思。这怎么解释POST和GET之间的行为差异? – 2014-08-28 22:47:40
