目前我在向Web API发布一些数据时遇到了问题。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,它创建了一个新的HTTP客户端,构建了一个JSON对象,并尝试将其发布到Web API控制器。然而,我一直在做发布操作时都会得到405(方法不允许...)的错误。我已经在互联网上寻找解决方案。我甚至已经检查了IIS Express中的处理程序,并将其与web.config中的内容进行了比较。但仍然没有运气。
所以这就是我的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,这里是我的控制台应用程序中一段试图进行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handlers的web.config配置:
<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>
我查看了iisexpress应用程序宿主配置文件。那里有很多处理程序,但我只会发布最后几个,因为那些似乎是相关的。还要注意的是,在任何地方都注释掉了WebDAV...
...
<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>
这个代码一直返回一个http 405错误。我这里有其他执行GET请求的方法,它们可以正常地访问端点。
值得注意的是,我使用了一个外部应用程序来执行POST请求,例如Postman,在请求体中发送了原始JSON数据。而且端点也被访问到了!似乎与iisexpress的设置有关,但我可能错了。
有人知道可能是什么问题吗?或者可以给我一些链接来揭示这个问题吗?
使用即时窗口进行调试时,我得到的响应对象如下:
