如何在vNext下的MVC 6中上传文件?

问题描述

在MVC 5中，我曾经这样做:

In MVC 5 I used to do this:

var context = (HttpContextBase)Request.Properties["MS_HttpContext"];
var file = (HttpPostedFileBase)context.Request.Files[0];

现在这些在vNext下的MVC 6中不可用.如何从请求中获取文件?

Now these are not available in MVC 6 under vNext. How can I get the file(s) from the request?

推荐答案

MVC6中尚未实现FileUpload，请参阅此问题，以及相关问题，例如此问题状态.

FileUpload isn't implemented in MVC6 yet, see this issue, and related issues such as this one for status.

您可以从JavaScript中发布 XMLHttpRequest 并将其捕获像这样的代码:

You can post an XMLHttpRequest from JavaScript and catch it with something like this code:

public async Task<IActionResult> UploadFile()
{
    Stream bodyStream = Context.Request.Body;

    using(FileStream fileStream = File.Create(string.Format(@"C:\{0}", fileName)))
    {

        await bodyStream.CopyToAsync(fileStream);

    }

  return new HttpStatusCodeResult(200);
}

如果您看到所链接的问题，则它们已关闭.您现在可以使用更普通的方式在MVC6中上传文件.

If you see the issues linked, they have now been closed. You can use a more normal way to upload files in MVC6 now.
