ASP.NET MVC URL路由问题

发布于 2024-09-03 03:03:52 字数 1918 浏览 3 评论 0原文

我定义了一个路由如下：

context.MapRoute("SearchEngineWebSearch", "search/web/{query}/{index}/{size}",
                            new
                            {
                                controller = "search",
                                action = "web",
                                query = "",
                                index = 0,
                                size = 5
                            });

和处理请求匹配的操作方法：

public System.Web.Mvc.ActionResult Web(string query = "", int index = 0, int size = 5)
    {
        if (string.IsNullOrEmpty(query))
            return RedirectToRoute("SearchEngineBasicSearch");
        var search = new Search();
        var results = search.PerformSearch(query, index, size);
        ViewData["Query"] = query;
        if (results != null && results.Count() > 0)
        {
            ViewData["Results"]= results;
            return View("Web");
        }
        else return View("Not-Found");
    }

以及将参数发送到操作方法的表单：

<% using (Html.BeginForm("Web", "Search", FormMethod.Post))
       { %>
    <input name="query" type="text" value="<%: ViewData["Query"]%>" class="search-field" />
    <input type="submit" value="Search" class="search-button" />
    <input type="hidden" name="index" value="2" />
    <input type="hidden" name="size" value="2" />
    <%} %>

现在单击提交并将值发送到操作方法后，所有路由值都会更新，但网址值仍然等于第一个发送参数的时间。例如，如果我发送第一次请求，例如 http://localhost/search/web/google下一次http://localhost/search/web/yahoo，传递给操作的查询参数方法是yahoo，但回发后的url仍然是 http://localhost/search/web/google ！

有人可以帮我吗？ ;)

i have defined a route as below:

context.MapRoute("SearchEngineWebSearch", "search/web/{query}/{index}/{size}",
                            new
                            {
                                controller = "search",
                                action = "web",
                                query = "",
                                index = 0,
                                size = 5
                            });

and action method to handle request match with that:

public System.Web.Mvc.ActionResult Web(string query = "", int index = 0, int size = 5)
    {
        if (string.IsNullOrEmpty(query))
            return RedirectToRoute("SearchEngineBasicSearch");
        var search = new Search();
        var results = search.PerformSearch(query, index, size);
        ViewData["Query"] = query;
        if (results != null && results.Count() > 0)
        {
            ViewData["Results"]= results;
            return View("Web");
        }
        else return View("Not-Found");
    }

and form to sent parameter to action method:

<% using (Html.BeginForm("Web", "Search", FormMethod.Post))
       { %>
    <input name="query" type="text" value="<%: ViewData["Query"]%>" class="search-field" />
    <input type="submit" value="Search" class="search-button" />
    <input type="hidden" name="index" value="2" />
    <input type="hidden" name="size" value="2" />
    <%} %>

now after click on submit and sending value to action method all route values updated but url values still is equals to first time of sending parameter. for example if i sent for first time request such as http://localhost/search/web/google and for next time http://localhost/search/web/yahoo, query parameter which passed to action method is yahoo but url after postback is http://localhost/search/web/google still!

can anybody help me plz? ;)

尝试类似的方法

return RedirectToAction("Web", 
   new { query = query, index = index, size = size});

来代替 return View("Web");。

另请注意，您应该执行 GET 而不是 POST。如果使用默认值提交，则索引和大小参数可以省略。

Try something like

return RedirectToAction("Web", 
   new { query = query, index = index, size = size});

instead of return View("Web");.

Also, note that you should perform a GET instead of a POST. And the index and size parameters may be ommitted if they were submitted with the default values.
