php - How to view files sent through x-sendfile as GET response

Question

I am using Slim Framework 3. Here's my code:

....
    $response = $response->withStatus(200)
                        ->withHeader('X-Sendfile', $path)
                        ->withHeader('Content-Type', $contentType)
                        ->withHeader('Content-disposition:', 'attachment; filename=' . $fileName);
                    return $response;
....

When using through postman, I see the image. But, how do I show the image / video / audio on an html page using the response?

Answer 1

由于整个文件由 x-sendfile 返回，因此该文件实际上是一个blob。因此，我在我的 javascript 中设置了responseType我的 ajax 请求。blob我按照@AdamZ 在Using Javascript to Display Blob上的回答，一切正常。
