Question

我有一个基本的股票标准ASP.Net 5 (ASP NET Core 1) MVC 6 (MVC Core 1)控制器，只有一种让我感到悲伤的方法。

以下是有问题的方法：

// Get the table data
[HttpPost("data/{requestedTable}")]
public IActionResult GetTableData(string requestedTable, [FromForm] DataTableData post)
{
    _logger.LogInformation($"About to process {requestedTable}");
    _logger.LogInformation($"Draw {post.Draw}, Start {post.Start}");
    if (!SQL.ValidTable(requestedTable))
    {
        return new ErrorObjectResult("Invalid table name specified");
    }

    var count = post.Length;
    var start = post.Start;
    var search = post.Search.Value;
    var draw = post.Draw + 1;

    var recordsTotal = new SQL()
            .WithCount()
            .AllData(requestedTable)
            .FirstOrDefault()["COUNT"];
    var recordsFiltered = new SQL()
            .WithCount()
            .WithSearch(search)
            .WithNavigation()
            .AllData(requestedTable)
            .FirstOrDefault()["COUNT"];
    var data = new SQL()
            .WithLimit(count, start)
            .WithSearch(search)
            .WithNavigation()
            .OrderBy(OrderHelper.Convert(post))
            .EnableDataTable()
            .AllData(requestedTable);

    _logger.LogInformation($"Got: {recordsTotal}, {recordsFiltered}, {data.Count()}");

    return new CustomObjectResult(new {
        draw = draw,
        recordsTotal = recordsTotal,
        recordsFiltered = recordsFiltered,
        data = data
    });
}

它在我的开发系统上运行100％（Windows 10 Pro，VS 2015 w / IIS Express，DNVM 1.0.0-rc1-update1）。

但是，当我通过VM在Windows Server 2012 R2上运行它时，我将获得大约10-20个失败请求的成功请求。

以下是我将收到的示例日志：

是否有人遇到类似/有任何可能解决此问题的建议修补程序/有任何与此相关的调试提示吗？

Answer 1

对于遇到此问题的人，[FromForm]似乎有问题，将其更改为[FromBody]并将其转换为具有相应类型的JSON已成功解决了此问题。

根据@BalaSakthis，以下问题在某种程度上解决了我的问题：ASP.NET 5 Controller method can't receive JSON POST, ASP.NET 4 controller method does

控制器未被调用
