When trying to download certain video it redirects to a new URL and the video starts to play. "disposable content type" is not received from server

Question

I want to download certain videos with a click. For that, I created a Button and attached a Function that should trigger the associated video download. But I am only able to download the link of the video, not the video. I am able to download videos with an external downloader or simply drag the URL to the download section of the browser. But unable to trigger that activity via JavaScript. Please help Me.

I tried multiple ways to tackle this problem:

1. Using a Simple Blob Technique without Axios:

const blob = new Blob([this.src_url], { type: 'video/mp4' })
const link = document.createElement('a')
link.href = URL.createObjectURL(blob)
link.download = this.src_url.replace(
>!     //   'https://redis-test.com/videos/',


link.click()
URL.revokeObjectURL(link.href)

endpoint: video URL get downloaded as a file of 122 bytes

2. Then using File Saver Package:

    var FileSaver = require('file-saver')
    console.log(this.src_url)  
    var blob = new Blob([this.src_url], { type: 'video/mp4' })
    FileSaver.saveAs(blob, 'hello world.mp4')

3. Then using the form method:

<form method="get" action="file.doc">
   <button type="submit">Download!</button>
</form>

endpoint: video starts to play in the same window

4. Using href download attribute:

function download(url) {
  const a = document.createElement('a')
  a.href = url
  a.download = url.split('/').pop()
  document.body.appendChild(a)
  a.click()
  document.body.removeChild(a)
}

endpoint: video starts to play in the same window

5. Using your method:

const link = document.createElement('a')
link.href = url
link.click()

endpoint: video starts to play in the same windows

6. With Axios defaults now:

  axios.defaults.withCredentials = true
     window.open(
       'https://cdn.pixaandom_urlrbay.com/vieo/487508532/Woman%20-%2058142.mp4?rendition=source&expiry=1666842719&hash=7dd6d178d9dbbd8adaf68dafd80c9167e91eca21&download'
     )

endpoint: video starts to play in the new window

7. With attaching disposable content type in headers with AXIOS:

 axios
       .get(
         String(nuxtConfig.axios.mediaURL) +
           this.src_url.replace(
             'https://redisrandom_url.com/videos/',
             ''
           ),
         {
           headers: {
             mode: 'no-cors',
             referrerPolicy: 'no-referrer',
             'Content-Disposition': 'attachment; filename=Woman - 58142.mp4',
             Host: 'redis-nfs',
             'User-Agent': 'PostmanRuntime/7.29.2',
             Accept: '*/*',
             'Accept-Language': 'en-US,en;q=0.5',
             'Accept-Encoding': 'gzip, deflate, br',
             Connection: 'keep-alive',
             Cookie:
               'tk_or=%22https%3A%2F%2Fwww.google.com%2F%22; tk_lr=%22https%3A%2F%2Fwww.google.com%2F%22; _gcl_au=1.1.954672920.1660108804; _ga=GA1.2.1392122600.1660108808; _fbp=fb.1.1660108809200.1970395787',

             'Sec-Fetch-Dest': 'document',
             'Sec-Fetch-Mode': 'navigate',
             'Sec-Fetch-Site': 'none',
             'Sec-Fetch-User': '?1',
             Pragma: 'no-cache',
             'Cache-Control': 'no-cache',
           },
         }
       )
       .then((response) => {
         console.log(response)

         const url = window.URL.createObjectURL(new Blob([response.data]))
         const link = document.createElement('a')
         link.href = url
         link.setAttribute('download', 'title')
         document.body.appendChild(link)
         link.click()
       })
       .catch((error) => {
         console.log('rex')
       })

endpoint: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at redis-random_url/videos/be319-72e1-2e79-8dc3-bcef1/…. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 200

"...But I am only able to download the link of the video, not the video."

I don't use VueJS but I suspect this.src_url is just text of the path to video URL.

In HTML5 you can only download those files that exist on your server. If the file is external then you need a PHP script (on same server as your HTML file) to read those external bytes back into your JS buffer array.

const blob = new Blob([this.src_url], { type: 'video/mp4' })

Should be:

let myBytes = //# update variable with data result of reading files bytes
let myBlob = new Blob(  [ Uint8Array.from( myBytes ) ] , {type: "application/octet-stream"} );

Where the bytes reading can be done with FileReader API or Fetch API.

When you can read a file's bytes into an Array using VueJS then your problem is solved.
