请求节点从 api 响应中获取结果

Question

我正在使用 request 进行 API 调用。

一切正常，但我实际上无法从响应中获得results。

我的代码是这样的

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);
    });

});

res.send(body); 如下所示。有谁知道我如何访问results？我试过body.results 但这不起作用。

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

Answer 1

所以首先你需要解析你的身体。 尝试这个。

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