[英].net Core 2.0 File Upload Size Limit
I'm having trouble with uploading large files in a .net core 2.0 MVC web app.我在 .net core 2.0 MVC Web 应用程序中上传大文件时遇到问题。
I have seen articles, such as this one, which shows how to increase the file size limit in .net core 2.0: Increase upload request length limit in Kestrel我看过一些文章,比如这篇文章,它展示了如何在 .net core 2.0 中增加文件大小限制: 增加 Kestrel 中的上传请求长度限制
So, following the example I have tried both options.因此,按照示例,我尝试了两种选择。 I currently have this in my Program.cs:
我目前在 Program.cs 中有这个:
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseKestrel(options => options.Limits.MaxRequestBodySize = null)
.Build();
... and my ajax file upload method on the controller looks like this: ...我在控制器上的 ajax 文件上传方法如下所示:
[HttpPost]
[RequestSizeLimit(1_074_790_400)]
[Route("api/article/uploadfile/{mediaType}")]
public async Task<IActionResult> UploadFile(string mediaType)
I'm access the uploaded files using Request.Form.Files
我正在使用
Request.Form.Files
访问上传的文件
The javascript on the view looks like this:视图上的 javascript 如下所示:
$('#upload-videos').change(function () {
var files = $("#upload-videos").get(0).files;
uploadMedia(false, files);
})
function uploadMedia(isPhoto, files) {
var type;
if (isPhoto) {
type = "i";
}
else {
type = "v";
}
var data = new FormData();
if (files.length > 0) {
for (idx = 0; idx < files.length; idx++) {
data.append("fileImage" + idx, files[idx]);
}
$.ajax({
url: "/api/article/uploadfile/" + type,
type: "POST",
processData: false,
contentType: false,
dataType: false,
data: data,
success: function (jsonData) {
refreshUploadedImages(jsonData, isPhoto);
}
});
}
}
The problem is, even with the changes to increase the upload limit in place, I am get the response:问题是,即使进行了增加上传限制的更改,我也得到了回应:
Failed to load resource: the server responded with a status of 500 ()
加载资源失败:服务器响应状态为 500()
If I put a break-point on the first line of the controller method it never hits it so it doesn't appear to be a problem with this code.如果我在控制器方法的第一行放置一个断点,它永远不会命中它,所以这段代码似乎没有问题。
Everything works fine with small files size but when I try to upload a file which is 538,286 KB in size it will fail.对于小文件大小一切正常,但是当我尝试上传大小为 538,286 KB 的文件时,它会失败。
Can anyone help with this?有人能帮忙吗?
Update: For further information, the problem seems to occur when the upload file size is somewhere between 122,211 KB and 137,840 KB regardless of any RequestSizeLimit settings, and it errors consistently.更新:有关更多信息,无论任何 RequestSizeLimit 设置如何,当上传文件大小介于 122,211 KB 和 137,840 KB 之间时,似乎都会出现此问题,并且始终出错。
Update 2: I've just updated all .net core and all .net core nuget packages to 2.1 but the problem still exists.更新 2:我刚刚将所有 .net core 和所有 .net core nuget 包更新到 2.1,但问题仍然存在。
To help anyone else with the same problem I have found the answer here: Max upload size for ASP.MVC CORE website为了帮助其他有同样问题的人,我在这里找到了答案: Max upload size for ASP.MVC CORE website
It turns out that you need to remove the body length limit like this:事实证明,您需要像这样删除主体长度限制:
services.Configure<FormOptions>(x => x.MultipartBodyLengthLimit = 1_074_790_400);
FormOptions
can be found in the Microsoft.AspNetCore.Http.Features
namespace. FormOptions
可以在Microsoft.AspNetCore.Http.Features
命名空间中找到。
To solve this problem you can use this code below instead要解决此问题,您可以使用下面的代码
[DisableRequestSizeLimit] [禁用请求大小限制]
