请求节点从api响应获取结果

Question

I am making an API call using request .

Everything is working ok, but I cannot actually get the results from the response.

My code looks like this

app.get('/events/:query', (req, res) => {

    request('http://www.skiddle.com/api/v1/events/search/?api_key=*****&keyword=elvis', (error, response, body) => {
        res.setHeader('Content-Type', 'application/json');
        res.send(body);
    });

});

The res.send(body); looks like the below. Does anyone know how I can access the results ? I have tried body.results but this doesn't work.

{  
   "error":0,
   "totalcount":"25",
   "pagecount":20,
   "results":[  
      {

Answer 1

So first you need to parse your body. Try this.

try {
    body = JSON.parse(body);
}
catch(err) {
    console.log(err);
}
res.send(body.results);
