Resource interpreted as Document but transferred with MIME type application/pdf

Question

See the following code:

Controller:

public ActionResult GetPDF()
{
    byte[] pdf = GetPdfFromDatabase();
    return new FileContentResult(reportData, "application/pdf");
}

View:

<iframe src="@Url.Action("GetPDF","Account")" width="600" height="500"></iframe>

Javascript Console:

Each time you load a page, show this warning !!!

Is the file not downloading or are you just concerned about the message? — KSib, Sep 21 '16 at 15:42

An iframe requests the resource mentioned in src attribute with a content type text/html. So this message only says "I requested html but server responded with pdf"

I believe the warning can't be ignored.

An alternative I found to this problem, use the object tag, like this:

and if you using angularJS, to prevent error on console do:

Could you clarify why you think this warning can't/shouldn't be ignored? – Sebastian Nov 08 '17 at 14:51

Sorry, it's just my opinion, but if you use the tip i sent, the warning will not be displayed. – Márcio Rossato Nov 08 '17 at 16:03

For who come across this topic. (Me too.) For best solution is you need to create HTML page to act as iframe landing page to show PDF content.

This is example html. I just extract from chrome.

<html><body style="background-color: rgb(38, 38, 38); height: 100%; width: 100%; overflow: hidden; margin: 0px;"><embed width="100%" height="100%" name="plugin" id="plugin" src="your_pdf_url" type="application/pdf"></body></html>

Just replace your_pdf_url to your real url. I just add this html as middleware in Laravel and show this HTML so Chrome will not warning anymore. You can use this html as base and create better pdf landing page such as custom loading.

Thank you brother, the warning disappeared. – Matheus Miranda Aug 01 '18 at 13:59 — Matheus Miranda, Aug 01 '18 at 13:59
