javascript - 在套接字 io 上使用 Node 请求库时出错

Question

我在 Laravel 项目上使用套接字 io，但在 socket.js 文件中的断开连接事件上的请求出现问题。

我已经调试了我的代码，错误出在请求库上。

Socket.js

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
var redis = require('redis');

server.listen(5000);

io.on('connection', function (socket) {
    console.log("new client connected " + socket.id);

    socket.on('disconnect', function() {
        var socket_id = socket.id;
        console.log('client disconnected :C '+socket_id);

        var request = require('request');
        var url_request = 'http://example.com/play-session/close?socket_id=' + socket_id;
        request(url_request, function (error, response, body) {
            if (!error && response.statusCode == 200) {
                console.log('session closed '+socket_id);
            }
        });
    });
});

错误:

SyntaxError: Error parsing /var/www/example.com/public_html/node_modules/aws4/package.json: Unexpected token <
    at Object.parse (native)
    at readPackage (module.js:113:52)

    at Object.<anonymous> (/var/www/example.com/public_html/node_modules/request/request.js:11:12)
    at Module._compile (module.js:456:26)

我不知道发生了什么。我感谢所有的帮助，谢谢。

已更新，问题已修复:

我用这个解决了这个问题: https://www.npmjs.com/package/request#unix-domain-sockets ，使用这个例子:

Socket.js

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
var redis = require('redis');
var request = require('request');

server.listen(5000);

io.on('connection', function (socket) {
    console.log("new client connected " + socket.id);

    socket.on('disconnect', function() {
        var socket_id = socket.id;
        console.log('client disconnected :C '+socket_id);

        var url_request = 'http://example.com/play-session/close?socket_id='+socket_id;
        request.get(url_request); // this line fix it
    });
});

感谢大家的帮助。
