405 Message, method not allowed with Web Api
提问by user1166905
I have got the following on an API controller:
我在 API 控制器上有以下内容：
public void UpdateClient(Client client)
{
try
{
if (ModelState.IsValid)
{
db.Entry(client).State = EntityState.Modified;
db.SaveChanges();
}
}
catch
{
throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.NotFound));
}
}
And the following on the page:
以及页面上的以下内容：
$.ajax({
url: "api/client/UpdateClient",
type: "PUT",
contentType: 'json',
data: ko.toJSON(model.selectedClient()),
success: function (result) {
getClients();
$("#loader").hide();
},
failure: function (result) {
alert(result.d);
$("#loader").hide();
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("An error occurred, please try again.");
$("#loader").hide();
}
});
But this gives the error 405 Method Not Allowed, can anyone see where I may have gone wrong? For reference the url for the api is ok as I use the same api controller for other functions too.
但这给出了错误 405 Method Not Allowed，谁能看到我哪里出错了？作为参考，api 的 url 没问题，因为我对其他功能也使用相同的 api 控制器。
Also the selectedClient() is a Client object received via WebApi so should match perfectly to PUT up again.
此外 selectedClient() 是通过 WebApi 接收的 Client 对象，因此应该与 PUT 再次完美匹配。

Looks like these two lines were wrong, I changed them as follows:
貌似这两行写错了，我改成如下：
contentType: 'application/json',
data: "{client: " + ko.toJSON(model.selectedClient()) + "}",
And now goes in.
现在进去了。

If you are using IIS7 and have WebDav installed, try removing it. I was getting the same error only with the PUT verb and it solved the issue
如果您使用的是 IIS7 并安装了 WebDav，请尝试将其删除。我只在 PUT 动词上遇到了同样的错误，它解决了这个问题
Update: You can read about WebDav here: http://www.iis.net/learn/get-started/whats-new-in-iis-7/what39s-new-for-webdav-and-iis-7
更新：您可以在此处阅读有关 WebDav 的信息：http://www.iis.net/learn/get-started/whats-new-in-iis-7/what39s-new-for-webdav-and-iis-7

Do you have [HttpPut] attribute on your UpdateClient action? Also, do you have a route that takes in the {action} as the routeTemplate? For example:
您的 UpdateClient 操作是否具有 [HttpPut] 属性？另外，您是否有将 {action} 作为 routeTemplate 的路线？例如：
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
One more thing, try 'application/json' for the content-type in your ajax code instead of 'json'.
还有一件事，尝试在 ajax 代码中为内容类型使用“application/json”而不是“json”。

Note to future troubleshooters: I got this error when my "Put" controller was unintentionally expecting an additional parameter that wasn't being used.
对未来故障排除者的注意：当我的“Put”控制器无意中期望一个未被使用的附加参数时，我收到了这个错误。

My issue was that under project properties, I was using Local IIS instead of IIS Express, and it defaulted to port 80 which blocked DELETE requests. Changing to IIS Express fixed it.
我的问题是在项目属性下，我使用的是本地 IIS 而不是 IIS Express，它默认为端口 80，它阻止了 DELETE 请求。更改为 IIS Express 修复了它。
