Node.js，wordpress，redis

Question

我需要从节点服务器中的Redis获取数据并将其发送到Wordpress布局。我尝试了以下，但data似乎并没有得到发送。

var express = require('express'); 
var app = express(); 
var redis = require('redis'); 
var client = redis.createClient(); //creates a new client 

client.on('connect', function() { 
    console.log('connected'); 
}); 

data = []; 

client.set(['first', 'Oleh']); 
client.set(['second', 'Ivan']); 
client.set(['thirt', 'Andriy']); 
client.set(['fourth', 'Olena']); 
client.set(['fifth', 'Kristy']); 
client.set(['sixth', 'Irina']); 

client.get('first', function (err, reply) { 
    console.log(reply); 
    data.push(reply); 
}); 

client.get('second', function (err, reply) { 
    console.log(reply); 
    data.push(reply); 
}); 

client.get('thirt', function (err, reply) { 
    console.log(reply); 
    data.push(reply); 
}); 

client.get('fourth', function (err, reply) { 
    console.log(reply); 
    data.push(reply); 
}); 

client.get('fifth', function (err, reply) { 
    console.log(reply); 
    data.push(reply); 
}); 

client.get('sixth', function (err, reply) { 
    console.log(reply); 
    data.push(reply) 
}); 

app.get('http://localhost/wordpress/', function (req, res) { 

    res.type('application/json'); // set content-type 
    res.send(this.data); // send text response 
    console.log(this.data); 
}); 

app.listen(process.env.PORT || 4730);

看来你的范围不正确。 this.data指的是function (req, res) {}，而不是您的全球范围。

尝试做res.json(data)并删除res.type()，因为res.json已经为您照顾。
