Adjusting the XHR 'Referer' header within a Chrome application

Is there a way to adjust the 'Referer' header in my Chrome app? When I try to set it using the following code:

xhr.setRequestHeader('Referer', 'http://example.com/');

I receive an error message that says:

ajax.js:15 Refused to set unsafe header "Referer"

I came across an older discussion where someone manipulated the 'Referer' field using chrome.webRequest, but this extension is no longer accessible in Chrome apps. Chrome.webRequest functionality has been deprecated! Despite many suggestions on Stack Overflow advising its use, it is no longer supported by Chrome. How can I update this header?

Answer №1

web-server-chrome provides a useful tool called ChromeSocketXMLHttpRequest. This object can be integrated into your project by cloning the repository and running minimize.sh to generate a single minimized file for easy inclusion. By utilizing ChromeSocketXMLHttpRequest, you can effectively substitute it for the standard XHR in your project.

Answer №2

Even though Chrome Apps cannot directly access the API, using the <webview> element provides a workaround with its request interface that can modify requests through the use of the webRequest feature.

This method involves creating a "proxy" page that handles XHR's on your behalf, embedding it within a webview, and then adjusting its requests as needed. While this adds an extra step, it does offer a solution to achieve the desired functionality.
