Using xhook to intercept XHR request

[FWeinb]

Thanks for building this extension! I am using rclonejs for something similar (amazon drive) using xhook.

const nameKey = new Uint8Array("Decrypted Key")
const nameTweak = new Uint8Array("Decrypted Tweak");
const cipher = PathCipher({nameKey, nameTweak});
const tryDecrypt = (name) => {
    try {
        name = cipher.decrypt(name);
    } catch (e) {
    }
    return name;
}
const sortAlphaDesc = (a,b) => {
    if (a.name < b.name)
        return -1;
    if (a.name > b.name)
        return 1;
    return 0;
}

const sortAlphaAsc = (b, a) => {
    if (a.name < b.name)
        return -1;
    if (a.name > b.name)
        return 1;
    return 0;
}

xhook.before((request) => {
    if (request.url.indexOf('/drive/v1/nodes') !== -1 && request.url.indexOf('filters') !== -1 ){
        console.log(request);
    }
});

xhook.after(function(request, response) {
    if (request.url.indexOf('/drive/v1/nodes') !== -1){
        const sortASC = request.url.indexOf("name+ASC") !== -1;
        const sortDESC = request.url.indexOf("name+DESC") !== -1;
        const req = JSON.parse(response.text);
        if (req.name) {
            req.name = tryDecrypt(req.name);
        }
        if (req.data) {
            req.data = req.data.filter(Boolean).map((item) => {
                item.name = tryDecrypt(item.name);
                return item;
            });
            if (sortASC) {
                req.data.sort(sortAlphaAsc);
            }
            if (sortDESC) {
                req.data.sort(sortAlphaDesc);
            }
        }
        response.text = JSON.stringify(req);
    }
});

I didn't look into Google Drive yet and don't know if a similar approach would be feasible.

Yea, I was thinking about that for a future version. When I browse on gdrive it makes a GETs to https://clients6.google.com/drive/v2internal/files with a response like this:

{
	"kind": "drive#fileList",
	"...": "...",
	"items": [{
			"...": "...",
			"title": "** ENCRYPTED FILE NAME **",
			"...": "..."
		},
		{
			"...": "...",
			"title": "** ENCRYPTED FILE NAME **",
			"...": "..."
		}
	]
}

This has the possibility of being intercepted and manipulated.
