 您可以使用nodeJs中提供的“http”模块发出http请求，然后处理从api调用收到的响应。 请看下面的例子 
 
var http = require('http');

var options = {
   host: 'example.com',
   port: 80,
   path: '/foo.html'
};

http.get(options, function(resp){
   resp.on('data', function(chunk){
   //do something with chunk
  });
}).on("error", function(e){
   console.log("Got error: " + e.message);
}); 

You can use "http" module available in nodeJs to make http request and then process the response recieved from the api call. Look at the below example
 
var http = require('http');

var options = {
   host: 'example.com',
   port: 80,
   path: '/foo.html'
};

http.get(options, function(resp){
   resp.on('data', function(chunk){
   //do something with chunk
  });
}).on("error", function(e){
   console.log("Got error: " + e.message);
});
