Node.js，wordpress，redis

Question

我需要從節點服務器中的Redis獲取數據並將其發送到Wordpress佈局。我嘗試了以下，但data似乎並沒有得到發送。

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); 

Answer 1

看來你的範圍不正確。 this.data指的是function (req, res) {}，而不是您的全球範圍。

嘗試做res.json(data)並刪除res.type()，因爲res.json已經爲您照顧。
