c# - C#、MVC、PUT 返回 405 Method Not Alowed

Question

我正在尝试发送 PUT 请求，但它总是返回 405 错误。我花了一个晚上试图修复它，我想我做了web.config中设置的所有组合，试图用不同的方法修改代码，我此时感到无助。也许我想念别的东西。我对mvc很新鲜。我对 GET 使用相同的方法，它工作正常。

这是js代码：

    var msg = {
        name: newName,
        description: newDesc
    };

    var stringMSG = JSON.stringify(msg);
    console.log(stringMSG);
    $.ajax({
        type: "PUT",
        url: '@Url.Action("PutSite", "Home")',
        async: true,
        cache: false,
        data: {
            id: id,
            json: stringMSG
        }
    }).done(function (result) {
        console.log(result);
    });

C# 控制器：

    [Authorize]
    public HttpResponseMessage PutSite(string id, string json)
    {
        return ApiProvider.UpdateSite(GetSessionId(), id, json);
    }

C# 类：

    public static HttpResponseMessage UpdateSite(string sessionID, string siteID, string json)
    {
        var client = GetHttpClient();
        var request = new HttpRequestMessage(HttpMethod.Put, $"{ApiBaseUrl}/api/session?id={sessionId}/site/{siteID}")
        {
            Content = new StringContent(json, Encoding.Default, "application/json")
        };

        return PutResponse(client, request);
    }

    private static HttpResponseMessage PutResponse(HttpClient client, HttpRequestMessage request)
    {
        var response = client.PutAsync(request.RequestUri,request.Content).Result;
        return response;
    }

    private static HttpClient GetHttpClient()
    {
        var client = new HttpClient();
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.TryAddWithoutValidation("Content-Type", "application/json; charset=utf-8");
        return client;
    }

和 web.config：
