如何解决HTTP错误404.15-未找到？

Question

我正在.NET Core 2.2应用程序中工作。调用API时收到HTTP错误404.15。

由于我在URL中传递的项目数量很大。

而且我没有如下所述更改IIS的特权。

<configuration>
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxQueryString="3000" maxUrl="1000" /> /* Change the Url limit here */
</requestFiltering>
</security>
</system.webServer>
</configuration>

我也尝试了以下解决方案，但不起作用。

[HttpPost]
[RequestSizeLimit(40000000)]
public async Task<IActionResult> UploadFiles(IFormFile file)
{

}

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
    .UseStartup<Startup>()
    .UseKestrel(options =>
    {
        options.Limits.MaxRequestBodySize = 52428800; //50MB
    });
}

app.UseWhen(context => context.Request.Path.StartsWithSegments("/api"), appBuilder =>
{
    context.Features.Get<IHttpMaxRequestBodySizeFeature>().MaxRequestBodySize = null;
    //TODO: take next steps
});

这是我的API调用

https://localhost:44473/ControllerName/InsertProduct?ProductSubCategoryId="4"&ProductName="Canon EOS 200D II DSLR Camera EF-S 18 - 55 mm IS STM and 55 - 250 mm IS STM  (Black)"&ProductDescription="Is photography one of your passions?

Flat 3% BACK for non-Prime members. No minimum order value. No upper limit on cashback."}]}"&ProductPrice="57499"&ProductBrand="Canon"&IsActive="True"&Quantity="50"&ImageURL="NULL"

控制器中的调用方法

public int InsertProduct(Product product)
{
    Dictionary<string, object> keyValues = this.GetProperty<Product>(product);

    int i = bl.AddProduct<Product>(keyValues);
    return i;
}

所以任何人都可以建议我一个更好的主意来解决此问题。

Answer 1

解决此问题的最简单方法是使用POST调用InsertProduct ...这样，查询字符串限制将不适用。

喜欢这个：

[HttpPost]
public int InsertProduct([FromBody]Product product)

此外，您将需要更改api调用以使用POST而不是GET。
