Question

我的应用程序使用名称填充数组。我可以记录数组值并获取值，但是使用邮递员在localhost:8888/api/messages上发出请求，我的响应显示matches : []空数组。如果我确实填充它，为什么我的数组在响应中为空？

router.get('/messages', function(request, res) {

  var names = [];
  ctxioClient.accounts(ID).contacts().get({limit:250, sort_by: "count", sort_order: "desc"}, 
    function ( err, response) {
      if(err) throw err;

      console.log("getting responses...");
      var contacts = response.body;
      var matches = contacts.matches;


      for (var i = 0; i < matches.length; i++){
        names.push(matches[i].name);
        matches[i].email;
      }  

    res.json({matches : names});   
  });


});

这是因为response.json()在ctxioclient.get()发生之前执行。在.get（）中调用response.json。像这样的东西

router.get('/messages', function(request, response) { // <--- router response
  var names = [];
  ctxioClient.accounts(ID).contacts().get({ limit: 250,sort_by: "count",sort_order: "desc"},function(err, resp) { // <---- using resp
      if (err) throw err;
      console.log("getting responses...");
      var contacts = response.body; 
      var matches = contacts.matches;
      for (var i = 0; i < matches.length; i++) {
        names.push(matches[i].name);
        matches[i].email;
      }
      response.json({ matches: names }); // <--- router response
    });
});

快速内置的API以空数组
