目前我在将一些数据发布到 Web API 时遇到问题。我有两个不同的项目。一个项目是运行 web api 2.0 的 web 应用程序。另一个项目是一个简单的控制台应用程序,它创建一个新的 http 客户端,构建一个 json 对象,并尝试将其发布到 web api Controller 。但是,发帖时我不断收到 405(方法不允许...)。我在网上搜索了解决方案。我什至检查了 IIS Express 中的处理程序,并将其与我在 web.config 中的处理程序进行了比较。仍然没有运气。
下面是我的 web api:
[RoutePrefix("api/media")]
[Authorize]
public class MultimediaController : ApiController
{
[HttpPost, Route("test")]
public IHttpActionResult Store([FromBody] TestRequest request) {
return Ok(request);
}
...
接下来,这是我的测试模型:
public class TestRequest {
public string testProp1 { get; set; }
public string testProp2 { get; set; }
}
然后,这是我的控制台应用程序中尝试执行 POST 的代码片段:
private const string testUrl = "/api/media/test/";
private async Task<bool> RunPostTest()
{
var httpClient = CreateHttpClient();
var content = JsonConvert.SerializeObject(new TestRequest {testProp1 = "hello", testProp2 = "world"});
var jsonContent = new StringContent(content, Encoding.UTF32, "application/json");
var response = await httpClient.PostAsync(testUrl, jsonContent);
if (response.StatusCode != System.Net.HttpStatusCode.OK)
{
Console.WriteLine($"Response code: {response.StatusCode}");
return false;
}
return true;
}
这是我的处理程序的 web.config:
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONSVerbHandler" />
<remove name="TRACEVerbHandler" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
我检查了 iisexpress applicationhost.config。那里有很多处理程序,但我只会发布最后几个,因为它们看起来是相关的。另请注意,WebDAV 到处都被注释掉了......
...
<add name="TRACEVerbHandler" path="*" verb="TRACE" modules="ProtocolSupportModule" requireAccess="None" />
<add name="OPTIONSVerbHandler" path="*" verb="OPTIONS" modules="ProtocolSupportModule" requireAccess="None" />
<add name="ExtensionlessUrl-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG" 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" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
<add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" responseBufferLimit="0" />
<add name="StaticFile" path="*" verb="*" modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule" resourceType="Either" requireAccess="Read" />
</handlers>
</system.webServer>
这会不断返回一个 http 405。我这里还有其他执行 GET 的方法,这些方法都很好地到达了终点。
同样值得注意的是,我使用了一个外部应用程序来执行一个帖子,例如 Postman,在正文中发送原始 json。终点被击中了!似乎与 iisexpress 的设置有关,但我可能是错的。
有人知道会发生什么情况吗?或者向我推荐一些可以发现问题的链接?

最佳答案
确保你在里面有 <system.webServer>
节Web.config
您的 API 项目的文件如下:
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule"/> <!-- add this -->
</modules>
此外,在处理程序部分:
<handlers>
<remove name="WebDAV" />
...
</handlers>
