【问题描述】：

我最近从 httpget 更改为 httppost，因此我可以将有效的 json 字符串放入我的请求正文中。现在，当我在本地运行 api 或通过发布到本地 IIS 发送请求时，一切都按我的预期工作。但是，一旦我部署到我们的开发 Web 服务器，“请求”就会丢失并到达代码行，返回 BadRequest(“Request is missing”);。

这是来自我的控制器的代码，

[RoutePrefix("MyPrefix")]
public class InsightController : ApiController
{
    [Route("Load"), AcceptVerbs("GET", "POST"), HttpPost, ResponseType(typeof(Logic))]
    public IHttpActionResult Load([FromBody]MasterRequest request)
    {
        try
        {
            if (!ModelState.IsValid)
                return BadRequest(ModelState);

            if (request.IsNull())
            {
                return BadRequest("Request is missing");
            }
...

WebApiConfig 代码如下所示，

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
        config.EnableCors(new EnableCorsAttribute("*", "*", "*"));
        config.Services.Insert(typeof(ModelBinderProvider), 0, new SimpleModelBinderProvider(typeof(MasterRequest), new RequestModelBinder()));
        config.Formatters.Add(new JsonMediaTypeFormatter());
        config.Formatters.Remove(config.Formatters.XmlFormatter);
        config.Formatters.JsonFormatter.SerializerSettings.Formatting = Newtonsoft.Json.Formatting.Indented;
        config.Formatters.JsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
    }
...

Web.Config，

<system.webServer>
    <modules>
      <remove name="FormsAuthentication" />
      <remove name="ApplicationInsightsWebTracking" />
      <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" preCondition="managedHandler" />
    </modules>
    <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>
  </system.webServer>
...

标头内容类型正确设置为 application/json 并通过邮递员使用原始 json 调用。

谁能指出我错过了什么？

谢谢。

邮递员中的 Json 响应，400 Bad Request { "message": "Request is missing" }
你能在帖子被调用之前显示请求的构造吗？
嗨，Bilpor，很遗憾，由于数据敏感，我不能。我只能说json字符串是有效的，因为我使用了站点link。
POST /api/MyPrefix/load HTTP/1.1 主机：dev.com 内容类型：application/json 缓存控制：无缓存邮递员令牌：fb584bf8-53ea-a2c4-b13b-5bcba1dade98
json 字符串太大，无法在此处发布，因此我已添加到上述原始问题的底部。

【解决方案1】：

事实证明，Web 服务器（负载平衡）将我的帖子重定向为 get（因此请求为空）。将网址更改为 https 并且有效。

@Bilpor 感谢您的帮助。
