[英]Web API Put Request generates an Http 405 Method Not Allowed error
這是對我的 Web API 上的PUT
方法的調用 - 方法中的第三行(我從 ASP.NET MVC 前端調用 Web API):
client.BaseAddress
是http://localhost/CallCOPAPI/
。
這是contactUri
:
這是contactUri.PathAndQuery
:
最后,這是我的 405 響應:
這是我的 Web API 項目中的 WebApi.config:
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "DefaultApiGet",
routeTemplate: "api/{controller}/{action}/{regionId}",
defaults: new { action = "Get" },
constraints: new { httpMethod = new HttpMethodConstraint("GET") });
var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
config.Formatters.Remove(config.Formatters.XmlFormatter);
我嘗試將傳遞到PutAsJsonAsync
的路徑剝離到string.Format("/api/department/{0}", department.Id)
和string.Format("http://localhost/CallCOPAPI/api/department/{0}", department.Id)
沒有運氣。
有沒有人知道為什么我會收到 405 錯誤?
更新
根據請求,這是我的部門控制器代碼(我將發布前端項目的部門控制器代碼以及 WebAPI 的部門 ApiController 代碼):

所以,我檢查了 Windows 功能以確保我沒有安裝這個叫做 WebDAV 的東西,它說我沒有。 無論如何,我繼續將以下內容放入我的 web.config(前端和 WebAPI,只是為了確定),現在它可以工作了。 我把它放在<system.webServer>
里面。
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule"/> <!-- add this -->
</modules>
此外,通常需要將以下內容添加到處理程序中的web.config
。 感謝巴巴克
<handlers>
<remove name="WebDAV" />
...
</handlers>
WebDav-SchmebDav .. ..確保您使用正確的 ID 創建了 url。 不要把它像http://www.fluff.com/api/Fluff?id=MyID ,把它像http://www.fluff.com/api/Fluff/MyID 。
例如。
PUT http://www.fluff.com/api/Fluff/123 HTTP/1.1
Host: www.fluff.com
Content-Length: 11
{"Data":"1"}
這讓我的球在短暫的永恆中徹底崩潰,完全尷尬。
將此添加到您的web.config
。 您需要告訴 IIS PUT
PATCH
DELETE
和OPTIONS
是什么意思。 以及調用哪個IHttpHandler
。
<configuation>
<system.webServer>
<handlers>
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
</configuration>
還要檢查您沒有啟用 WebDAV。
我正在 IIS 8.5 上運行 ASP.NET MVC 5 應用程序。 我嘗試了這里發布的所有變體,這就是我的web.config
樣子:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule"/> <!-- add this -->
</modules>
<handlers>
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="WebDAV" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
我無法從我的服務器上卸載 WebDav,因為我沒有管理員權限。 另外,有時我會在 .css 和 .js 文件中method not allowed
的method not allowed
。 最后,有了上面的配置,一切又開始工作了。
用 [FromBody] 裝飾其中一個動作參數為我解決了這個問題:
public async Task<IHttpActionResult> SetAmountOnEntry(string id, [FromBody]int amount)
但是,如果在方法參數中使用了復雜對象,ASP.NET 將正確推斷它:
public async Task<IHttpActionResult> UpdateEntry(string id, MyEntry entry)
另一個原因可能是如果您不使用“id”的默認變量名稱,實際上是:id。
在我的情況下,由於路由(“api/images”)與同名文件夾(“~/images”)沖突,靜態處理程序調用了錯誤 405。
您可以從 GUI 中手動刪除 webdav 模塊,以便在 IIS 中進行特定操作。
1) 轉到 IIs。
2) 轉到相應的站點。
3)打開“處理程序映射”
4) 向下滾動並選擇 WebDav 模塊。 右鍵單擊它並刪除它。
注意:這也將更新您的 web 應用程序的 web.config。
這個簡單的問題可能會引起真正的頭痛!
我可以看到您的控制器EDIT
( PUT
) 方法需要 2 個參數:a) 一個 int id,以及 b) 一個部門對象。
當您從 VS > 添加帶有讀/寫選項的控制器生成此代碼時,它是默認代碼。 但是一定要記得使用這兩個參數消費這個服務,否則會報405錯誤。
就我而言,我不需要PUT
的 id 參數,所以我只是將它從標題中刪除......幾個小時后沒有注意到它! 如果您將其保留在那里,則該名稱也必須保留為 id,除非您繼續對配置進行必要的更改。
