Question

我刚刚将我的Azure Web App从aspnetcore rc2更新为aspnetcore 1.0，.net framework 4.6.2和预览2工具。由于这个改变，我遇到了一个问题，在部署后的第一分钟左右，我的控制器没有获得任何POST数据。应包含它的对象始终为null。大约一分钟后，代码开始按预期工作。第一次网络通话的响应时间现在看起来要快得多，让我怀疑在应用程序完全初始化之前我的应用程序正在发送请求。只有在部署到Azure时，才会在本地发生这种情况。

在开始接收请求之前，我是否需要做些什么来确保应用程序完全初始化？

如果我尝试直接访问this.HttpContext.Request.Body，那么它会抛出

Cannot access a disposed object. Object name: 'FileBufferingReadStream'.

我的project.json看起来像是相关的：

{
  "version": "1.0.0-*",
  "buildOptions": {
    "emitEntryPoint": true
  },

  "runtimeOptions": {
    "gcServer": true
  },

  "dependencies": {
    "Microsoft.Extensions.Configuration.Json": "1.0.0",
    "Microsoft.Extensions.Logging": "1.0.0",
    "Microsoft.Extensions.Logging.Console": "1.0.0",
    "Microsoft.Extensions.Logging.Debug": "1.0.0",
    "Microsoft.AspNetCore.Hosting": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel.Https": "1.0.0",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
    "Newtonsoft.Json": "9.0.1"
  },

  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": {
      "version": "1.0.0-preview2-final",
      "imports": "portable-net45+win8+dnxcore50"
    }
  },

    "frameworks": {
      "net462": {
      }
    },
    "publishOptions": {
      "include": [
        "wwwroot",
        "Views",
        "appsettings.json",
        "web.config"
      ]
    },

    "userSecretsId": "redacted",

    "scripts": {
      "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
    }
  }

控制器的代码非常简单。在第一分钟左右，这将返回badrequest，之后相同的请求将返回Ok。

    [HttpPost]
    [Produces( "application/json" )]
    public IActionResult Post( [FromBody] MyRequestDataClass RequestData )
    {
        if (RequestData == null)
        {
            return BadRequest();
        }
        return Ok();
    }

AspNetCore最初没有在框架4.6.2中获取POST数据
