Question

我一般都使用新的Node.js和服务器端脚本，目前正在使用此处的brewerydb-node包装器进行练习（https://www.npmjs.com/package/brewerydb-node）

我目前有以下服务器端代码，它将相应的JSON对象记录到命令行

var express = require('express');
var app = express();
var morgan = require('morgan');
var bodyParser = require('body-parser');
var BreweryDb = require('brewerydb-node');
var brewdb = new BreweryDb([api-key here]);
var request = require('request');

app.use(bodyParser.json()); 

brewdb.breweries.getById("g0jHqt", {}, function(err, beer) {
    if(err) {
        console.log(res.statusCode());
    } else {
        console.log(beer.name);
    }
})

app.listen(8000, function() {
    console.log("Listening at http://localhost:8000");
})

我不确定如何将此对象作为响应发送，我可以使用我的客户端代码解析，因为没有＆＃39; res＆＃39;或者＆＃39; req＆＃39;这个包装器中的参数。

您希望将请求包含在路由中，如下所示：

var express = require('express');
var app = express();
var morgan = require('morgan');
var bodyParser = require('body-parser');
var BreweryDb = require('brewerydb-node');
var brewdb = new BreweryDb([api-key here]);
var request = require('request');

app.use(bodyParser.json()); 

app.get('/breweries/:id', function(req,res){
  // in here a request to http://localhost:8000/breweries/g0jHqt will fetch the same as your example code
  brewdb.breweries.getById(req.params.id, {}, function(err, beer) {
    if(err) {
        console.error(err);
        res.status(500).send("An error occurred"); 
    } else if(beer) { // we found the beer
        res.send(beer);
    } else{
        res.status(404).send('We could not find your beer');
    }
  })
});

app.listen(8000, function() {
    console.log("Listening at http://localhost:8000");
})

在Node.JS中从服务器端向客户端发送GET请求JSON对象
