Question

我需要将大量数据发布到我的API

        [HttpPost]
        [RequestSizeLimit(40000000)]
        [Route("PostList")]
        public async Task<IActionResult> PostList([FromBody] IEnumerable<ItemMasterDto> data)
        {
            // Do work
            return Ok();
        }

要发布的示例数据就像

[
  {
    "ExternalMappingId": "I-01",
    "GroupName": "string",
    "SubGroupName": "string",
    "DisplayItemCode": "string",
    "ItemDescription": "string",
    "DispItemDescription": "string",
    "ItemSubDescription": "string",
    "UnitSet": "string",
    "DefaultTranUnitCode": "string",
    "DefaultReportUnitCode": "string",
    "IsVatExempted": true,
    "IsImported": true,
    "IsVATApplicable": true,
    "IsSaleable": true,
    "HSCode": "string",
    "VATPercent": 0,
    "IsManufacturing": true
  }
  {
    "ExternalMappingId": "I-02",
    "GroupName": "string",
    "SubGroupName": "string",
    "DisplayItemCode": "string",
    "ItemDescription": "string",
    "DispItemDescription": "string",
    "ItemSubDescription": "string",
    "UnitSet": "string",
    "DefaultTranUnitCode": "string",
    "DefaultReportUnitCode": "string",
    "IsVatExempted": true,
    "IsImported": true,
    "IsVATApplicable": true,
    "IsSaleable": true,
    "HSCode": "string",
    "VATPercent": 0,
    "IsManufacturing": true
  }
]

使用少量数据可以正常工作，但是当我尝试发布更多数据时，则100k数据API拒绝连接，并且我收到呼叫失败，状态码404（未找到）的错误。如您所见，我已经尝试过[RequestSizeLimit(40000000)，并且在Startup.cs

中也尝试了以下操作

        services.Configure<FormOptions>(o =>
            {
                o.ValueLengthLimit = int.MaxValue;
                o.MultipartBodyLengthLimit = long.MaxValue;
                o.MultipartBoundaryLengthLimit = int.MaxValue;
                o.MultipartHeadersCountLimit = int.MaxValue;
                o.MultipartHeadersLengthLimit = int.MaxValue;
                o.BufferBodyLengthLimit = long.MaxValue;
            });

我的总数据可能在100k到200k之间。我能做什么？？谢谢。

尝试更新您的配置文件requestLimits

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    ...
    <security>
      <requestFiltering>
        <!-- This will handle requests up to 50MB -->
        <requestLimits maxAllowedContentLength="52428800" />
      </requestFiltering>
    </security>
   ...
  </system.webServer>
</configuration>
