如何使用ExpressJS在XML中进行回应？ [英] How can I respond in XML using ExpressJS?

问题描述

我有一个简单的代码，为特定的路由提供JSON响应。这是我当前的代码：

I have a simple code that gives a JSON response for a specific route. Here's my current code:

var express = require('express')
  , async = require('async')
  , http = require('http')
  , mysql = require('mysql');

var app = express();

var connection = mysql.createConnection({
    host: 'localhost',
    user: '****',
    password: "****",
    database: 'restaurants'
});

connection.connect();

// all environments
app.set('port', process.env.PORT || 1235);
app.use(express.static(__dirname + '/public/images'));


app.get('/DescriptionSortedRating/',function(request,response){
    var name_of_restaurants;

    async.series( [
        // Get the first table contents
        function ( callback ) {
            connection.query('SELECT * FROM restaurants ORDER BY restaurantRATING', function(err, rows, fields)
                {
                        console.log('Connection result error '+err);
                        name_of_restaurants = rows;
                        callback();
                });

 }
   // Send the response
], function ( error, results ) {
    response.json({
        'restaurants' : name_of_restaurants
    });
} );

} );



http.createServer(app).listen(app.get('port'), function(){
  console.log('Express server listening on port ' + app.get('port'));
});

如何使XML等同于上述JSON？

How can I make an XML response equivalent to the JSON above?

推荐答案

您可以使用npm上可用的任意数量的XML库。以下是使用简单命名的 xml 库的示例：

You can use any number of the XML libraries available on npm. Here's an example using the simply-named "xml" library:

var xml = require('xml');

response.set('Content-Type', 'text/xml');
response.send(xml(name_of_restaurants));

有关如何将JavaScript对象转换为XML的说明，请参阅模块的文档。如果您需要以特定XML格式返回的东西，那么您当然会有更多的工作要做。

See the module's documentation for a description of how it converts JavaScript objects to XML. If you need things returned in a specific XML format, you'll have more work to do, of course.
