【问题描述】:
我在做什么:: 我正在尝试为数据库中的数据集生成 json 和 xml 输出
Express Code:: 这里我正在尝试 JSON 响应
var express = require('express')
, async = require('async')
, http = require('http')
, mysql = require('mysql');
var xml = require('xml');
var app = express();
var connection = mysql.createConnection({
host: 'localhost',
user: 'root',
database: 'MyDatabase'
});
connection.connect();
// all environments
app.set('port', process.env.PORT || 3007);
app.use(express.static(__dirname + '/public/images'));
app.get('/Result/',function(request,response){
var name_of_restaurants;
async.series( [
// Get the first table contents
function ( callback ) {
connection.query('SELECT * FROM mas_buf_type', 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 });
//response.set('Content-Type', 'text/xml');
//response.send(xml(name_of_restaurants));
} );
} );
http.createServer(app).listen(app.get('port'),function(){
console.log('Express server listening on port'+app.get('port'));
});
我的输出::
{
"restaurants": [
{
"Buf_Type_Id": 1,
"Buf_Type_Name": "Breakfast"
},
{
"Buf_Type_Id": 2,
"Buf_Type_Name": "Lunch"
},
{
"Buf_Type_Id": 3,
"Buf_Type_Name": "Dinner"
}
]
}
现在代替
response.json({'restaurants' : name_of_restaurants });
我添加了这些行以获得XML 输出
response.set('Content-Type', 'text/xml');
response.send(xml(name_of_restaurants));
输出::
<Buf_Type_Id>1</Buf_Type_Id>
<Buf_Type_Id>2</Buf_Type_Id>
<Buf_Type_Id>3</Buf_Type_Id>
我的问题::
- 很明显,你可以看到两个输出不同,我找不到 xml 输出中的第二列
- 如何解决此问题
- 我需要进行哪些更改
{编辑}
var express = require('express')
, async = require('async')
, http = require('http')
, mysql = require('mysql');
var xml = require('xml');
var app = express();
var connection = mysql.createConnection({
host: 'localhost',
user: 'root',
database: 'findmybuffet'
});
connection.connect();
// all environments
app.set('port', process.env.PORT || 3007);
app.use(express.static(__dirname + '/public/images'));
app.get('/Result/',function(request,response){
var name_of_restaurants;
async.series( [
// Get the first table contents
function ( callback ) {
connection.query('SELECT * FROM mas_buf_type', 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 });
response.set('Content-Type', 'text/xml');
//response.send(xml(name_of_restaurants));
response.send(xml({restaurants:[
name_of_restaurants.map(function(r){
return [
{ Buf_Type_Id: r.Buf_Type_Id },
{ Buf_Type_Name: r.Buf_Type_Name },
]
})
]}));
} );
} );
http.createServer(app).listen(app.get('port'),function(){
console.log('Express server listening on port'+app.get('port'));
});
输出::
<restaurants>
<0>
<Buf_Type_Id>1</Buf_Type_Id>
<Buf_Type_Name>Breakfast</Buf_Type_Name>
</0>
</restaurants>
我们还可以清楚地看到<0> 正在生成......这不是必需的......如何删除它?
