ASP.Net 核心内容处理附件/内联 [英] ASP.Net Core Content-Disposition attachment/inline

问题描述

我正在从 WebAPI 控制器返回一个文件.Content-Disposition 标头值自动设置为附件".例如:

I am returning a file from a WebAPI controller. The Content-Disposition header value is automatically set to "attachment". For example:

处置:附件；文件名="30956.pdf";文件名*=UTF-8''30956.pdf

Disposition: attachment; filename="30956.pdf"; filename*=UTF-8''30956.pdf

当它设置为附件时，浏览器将要求保存文件而不是打开它.我想打开它.

When it is set to attachment the browser will ask to save file instead of opening it. I would like it to open it.

如何将其设置为内联"而不是附件"?

How can I set it to "inline" instead of "attachment"?

我使用这种方法发送文件:

I am sending the file using this method:

public IActionResult GetDocument(int id)
{
    var filename = $"folder/{id}.pdf";
    var fileContentResult = new FileContentResult(File.ReadAllBytes(filename), "application/pdf")
    {
        FileDownloadName = $"{id}.pdf"
    };
    // I need to delete file after me
    System.IO.File.Delete(filename);

    return fileContentResult;
}

推荐答案

使用 AspNetCore 和 AspNetCore.Mvc 的 2.0.0 版，我没有找到以前的答案可以接受.对我来说，只需将文件名参数省略给 File 就足以触发内联内容处置.

With version 2.0.0 of AspNetCore and AspNetCore.Mvc, I found none of the previous answers to be acceptable. For me, simply ommitting the filename argument to File was enough to trigger an inline content disposition.

return File(fileStream, contentType, fileName); // attachment
return File(fileStream, contentType);           // inline
