如何增加上传文件的大小限制?

How to increase the limit on the size of the uploaded file?

我正在使用 ABP Zero Core MVC template (ASP.Net Core 2.x, MVC, jQuery) version 4.2.0. When I try to upload a file using the AJAX to controller, I get an HTTP 404.13 error, which indicates that the maximum file size is exceeded. and here 我找到了类似问题的解决方案并尝试如此准确地解决了它,但它们要么不符合所使用的模式,要么我做错了什么。

如何在零核心中增加最大上传文件大小?

// *.Web.Host\Startup\Program.cs 
// *.Web.Mvc\Startup\Program.cs
public static IWebHostBuilder CreateWebHostBuilder(string[] args) {
    return WebHost.CreateDefaultBuilder(args)
        .UseKestrel(options => { 
            // no effect...  I can only small files uploaded
            options.Limits.MaxRequestBodySize = 1024 * 1024 * 1024; 
        })
        .UseStartup<Startup>();
}

试试这个

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
  //add to beginning of the method... 
  services.Configure<FormOptions>(x =>
  {
      x.ValueLengthLimit = int.MaxValue;
      x.MultipartBodyLengthLimit = int.MaxValue;
      x.MultipartHeadersLengthLimit = int.MaxValue;
  });


}

您是否尝试过用 [RequestSizeLimit(YOUR_MAX_TOTAL_UPLOAD_SIZE)] 装饰控制器 action 以及 Startup.cs 中的变化?

services.Configure<FormOptions>(opt =>
{
    opt.MultipartBodyLengthLimit = YOUR_MAX_TOTAL_UPLOAD_SIZE;
});

顺便说一句,如果您打算在 IIS 上托管该应用程序,您可以将 web.config 文件添加到您的项目并在那里配置 upload size,而不是在 IIS 服务器上配置它。

编辑:作为 @XelaNimed 的评论,添加 web.config 文件并编辑 startup.cs,使代码正常工作。
