ASP.NET MVC 3 HttpPost动作方法未找到 [英] ASP.NET MVC 3 HttpPost action method not found
问题描述
我有一个简单的表格，职位，一个 HttpPost 操作方法，该方法返回其对应的视图。我的问题是，我得到一个 404未找到错误。奇怪的是，如果我改变了形式方法和行动上法属性的 GET ，那么它的工作原理，并显示TestMethod的视图。
我似乎失去了一些东西，使用 POST ，但我在其他控制器岗位正常工作（例如帐户登录和注册）。注意使用AllowAnonymous 属性自定义属性，以便能够指定允许匿名访问的控制器或动作，而不是指定（通过授权 attr）使用需要授权的控制器或动作。我想没有什么是不可能的，但我不认为这有什么与我的问题。对什么是错的任何想法？

我想我终于找到了罪魁祸首。首先，我要承认，现在是什么问题是知道，这个问题的标题是不是很准确。这个问题主要涉及在Web.config中的规则重写。直到听取别人的意见对这个问题，我已经完全忘记了有关规则的重写，这就是为什么我没有查出来再开始。
总之，问题是重写URL以全部小写的规则。我知道我的帐户注册和登录表单都工作正常，所以我检查出来，发现自己的 Html.BeginForm 声明是无参数，其中，显然会导致一个小写的URL为产生的。我想为我的测试方法参数的POST请求，和它的工作。然后，我尝试使用在 Html.BeginForm 语句行动和控制器参数，但是这一次我进入他们为小写字符串： Html.BeginForm（ TestMethod的，测试...）。果然，它也工作得很好，而页面的源代码显示的形式行动小写。
要解决我的问题，我不得不设置一个条件不匹配 POST 请求：＆LT;添加输入={REQUEST_METHOD}使用MatchType =模式模式=POST否定=TRUE/＆GT; 。请注意，这个问题是没有明确的规则，小写字母，而是在 POST 请求被重定向。我发现，讨论<$的问题的一种博客 C $ C> POST 重定向被转换为 GET 和造成的错误，这是exaclty我正经历。这是一对夫妇岁，但显然它仍然是相关信息。
在任何情况下，我现在备份和运行。感谢所有谁在他们的两分钱扔去。
P.S。当我关闭浏览器选项卡和结束我的搜索，我想我会链接到本SO <一个href=\"http://stackoverflow.com/questions/5994261/in-the-iis7-url-rewrite-module-can-i-specify-in-a-redirect-rule-to-not-apply-to\">question,因为它肯定是与我的问题。
I have a simple form that posts to an HttpPost action method, which returns its corresponding view. My issue is that I'm getting a 404 Not Found error. Oddly enough, if I change the form method and the attribute on the action method to a GET, then it works and the TestMethod view is displayed.
It seems I'm missing something for using POST, but my posts in other controllers work fine (e.g. account login and registration). Note the AllowAnonymous attribute is a custom attribute to be able to specify the controllers or actions that allow anonymous access, as opposed to specifying (via the Authorize attr) the controllers or actions that require authorization. I guess nothing is impossible, but I don't think that has anything to do with my issue. Any thoughts on what is wrong?
FORM:
@using (Html.BeginForm("TestMethod", "Test", FormMethod.Post, new { @id = "testForm" })) {
<fieldset>
<legend>Test Form</legend>
<input type="submit" value="Submit" />
</fieldset>
}
CONTROLLER ACTION:
[AllowAnonymous]
[HttpPost]
public ActionResult TestMethod() {
return View();
}
VIEW:
<h2>TestMethod</h2>
<p>HttpPost method was successful.</p>
REGISTER ROUTES METHOD FROM Global.asax.cs:
public static void RegisterRoutes(RouteCollection routes) {
routes.IgnoreRoute("favicon.ico");
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
// About
routes.MapRoute(
"About", // Route name
"about", // URL with parameters
new { controller = "Home", action = "About" } // Parameter defaults
);
// Faq
routes.MapRoute(
"Faq", // Route name
"faq", // URL with parameters
new { controller = "Home", action = "Faq" } // Parameter defaults
);
// Glossary
routes.MapRoute(
"Glossary", // Route name
"glossary", // URL with parameters
new { controller = "Home", action = "Glossary" } // Parameter defaults
);
// Register
routes.MapRoute(
"Register", // Route name
"register", // URL with parameters
new { controller = "Account", action = "Register" } // Parameter defaults

// LogIn
routes.MapRoute(
"LogIn", // Route name
"login/{id}", // URL with parameters
new { controller = "Account", action = "LogOn", id = UrlParameter.Optional } // Parameter defaults

routes.MapRoute(
"LogOn", // Route name
"logon/{id}", // URL with parameters
new { controller = "Account", action = "LogOn", id = UrlParameter.Optional } // Parameter defaults

// Default
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults

}
AUTHORIZE ATTRIBUTE CODE:
// AllowAnonymousAttribute class
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public sealed class AllowAnonymousAttribute : Attribute { }
// GlobalAuthorize class
public sealed class GlobalAuthorize : AuthorizeAttribute {
public override void OnAuthorization(AuthorizationContext filterContext) {
bool skipAuthorization =
filterContext.ActionDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true) ||
filterContext.ActionDescriptor.ControllerDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true);
if (!skipAuthorization) base.OnAuthorization(filterContext);
}
}
// RedirectAuthorizeAttribute class
public class RedirectAuthorizeAttribute : AuthorizeAttribute {
public string RedirectUrl { get; set; }
protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext) {
filterContext.Result = new RedirectResult(RedirectUrl);
}
}
GLOBAL FILTERS:
public static void RegisterGlobalFilters(GlobalFilterCollection filters) {
filters.Add(new RequireHttpsAttribute());
filters.Add(new GlobalAuthorize());
filters.Add(new HandleErrorAttribute());
}
ROUTE REWRITING RULES:
<rewrite>
<rules>
<!-- Block all requests made to a website that do not have the host header set. -->
<rule name="Fail bad requests" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{HTTP_HOST}" pattern="localhost" negate="true" />
</conditions>
<action type="AbortRequest" />
</rule>
<!-- Remove trailing slash from all incoming requests. -->
<rule name="Remove trailing slash" stopProcessing="false">
<match url="(.*)/$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />

</rule>
<!-- Convert all requests to all lowercase. -->
<rule name="Convert to lowercase" stopProcessing="false">
<match url=".*[A-Z].*" ignoreCase="false" />
<action type="Redirect" url="{ToLower:{R:0}}" redirectType="Permanent" />
</rule>
<!-- Any URL with (HTTPS == OFF) and (HTTP_HOST with colon) -> use for development testing. -->
<rule name="Development redirect to HTTPS" enabled="true" stopProcessing="true">
<match url=".*" ignoreCase="true" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="true">
<add input="{HTTPS}" pattern="^OFF$" />
<add input="{HTTP_HOST}" pattern="([^/:]*?):[^/]*?" />
</conditions>
<action type="Redirect" url="https://{C:1}:44300{URL}" />
</rule>
<!-- Redirect any HTTP request to HTTPS. -->
<rule name="Redirect to HTTPS" stopProcessing="true">

<conditions>
<add input="{HTTPS}" pattern="^OFF$" ignoreCase="true" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" />
</rule>
</rules>
</rewrite>
I think I finally found the culprit. First of all, I'll concede that, knowing now what the issue was, the title of this question isn't very accurate. The problem mostly dealt with a rule rewrite in Web.config. Until responding to others' comments for this question, I had completely forgotten about the rule rewrites, which is why I hadn't checked them out further to begin with.
Anyway, the issue was a rule that rewrote URLs to all lowercase. I knew my account registration and login forms were working fine, so I checked them out and noticed that their Html.BeginForm statements were parameterless, which, evidently results in a lowercase url being generated. I tried parameterless POST request for my test method, and it worked. Then, I tried using parameters for action and controller in the Html.BeginForm statement, but this time I entered them as lowercase strings: Html.BeginForm("testmethod", "test"...). Sure enough, it, too, worked just fine, and the page source showed the form action as lowercase.
To fix my problem, I just had to set a condition to not match POST requests: <add input="{REQUEST_METHOD}" matchType="Pattern" pattern="POST" negate="true" />. Note that the issue was not the lowercase rule specifically, but rather that the POST request was being redirected. I found one blog that discusses the issue of POST redirects being converted to GETs and resulting in errors, which is exaclty what I was experiencing. It's a couple years old, but apparently it's still pertinent info.
At any rate, I'm now back up and running. Thanks to all who threw in their two cents.
P.S. As I'm closing browser tabs and concluding my search, I figured I'd link to this SO question, as it is definitely related to my issue.
