How To Request Images And Output Image In Node.js

I try to get the image and display on a url. and I use request module. For example, I want to get the image https://www.google.com/images/srpr/logo11w.png, and display on my url ht

Solution 1:

Try specifying encoding: null when making the request so that the response body is a Buffer that you can directly write to the response stream:

app.get("/google/logo", function(req, res) {
    var requestSettings = {
        url: 'https://www.google.com/images/srpr/logo11w.png',
        method: 'GET',
        encoding: null
    };

    request(requestSettings, function(error, response, body) {
        res.set('Content-Type', 'image/png');
        res.send(body);
    });
});

On the other hand if you do not specify encoding: null, the body parameter will be a String instead of a Buffer.

Solution 2:

That seems an overkill, you can just ask the browser the get the url directly like this;

app.get("/google/logo", function(req, res) {
res.writeHead(302, {location:"https://www.google.com/images/srpr/logo11w.png"});
res.end();
})
