套接字连接失败总是

问题描述

我正在写一个连接到帆的应用程序服务器。

此应用程序与科尔多瓦， angularJS 书面和离子。

当我在浏览器中启动我的应用程序（以离子服务）的插座将无法连接到服务器。下面是我得到的消息：

  GET http://localhost:8100/socket.io/?__sails_io_sdk_version=0.11.0&__sails_io_s…sails_io_sdk_language=javascript&EIO=3&transport=polling&t=1443472067762-4错误（404）
 

服务器运行的是本地端口1337.我试图改变上述网址为：

<$p$p><$c$c>http://localhost:1337/socket.io/?__sails_io_sdk_version=0.11.0&__sails_io_s…sails_io_sdk_language=javascript&EIO=3&transport=polling&t=1443472067762-4

和它的工作。

在我的code我设置后的网址 sails.io.js 已包含：

  io.sails.url =的http：//本地主机：1337';
io.sails.useCORSRouteToGetCookie = FALSE;
 

为什么要问本地主机：8100 ，而不是本地主机：1337

当我在移动设备启动这个应用程序（该URL设置为 http://192.168.1.10:1337 ），它的正常工作。

的版本 sails.io.js 是 0.11.6 和版本的帆是 0.11.0

解决方案

我终于找到了解决办法（但我很抱歉，我不记得在那里我发现它：（）

问题是， io.sails.url =的http：//本地主机：1337'; 是第一个JS周期后，从而帆执行，插座已经被加载。 （这是（从我的理解），因为在一些浏览器如果code是在另一个剧本标记它在另一个周期执行）

要使它工作，我收到我包括帆插座脚本中加入此code：

  VAR apiHost ='localhost'的;
            （函数（）{
                VAR IO;
                Object.defineProperty（窗口，IO，{
                    得到：函数（）{
                        返回IO;
                    }，
                    设置：功能（值）{
                        VAR帆;
                        IO =价值;
                        Object.defineProperty（IO，'帆'，{
                            得到：函数（）{
                                返回帆;
                            }，
                            设置：功能（值）{
                                帆=价值;
                                sails.url =的http：//+ apiHost +'：1337';
                                sails.useCORSRouteToGetCookie = FALSE;
                            }
                        }）;
                    }
                }）;
            }）（）;
 

I'm writing an application that connects to a sails server.

This application is written with cordova, angularJS and Ionic.

When I launch my application in my browser (with ionic serve) the socket fails to connect to the server. Here is the message I get:

GET http://localhost:8100/socket.io/?__sails_io_sdk_version=0.11.0&__sails_io_s…sails_io_sdk_language=javascript&EIO=3&transport=polling&t=1443472067762-4 404 (Not Found)

The server is running locally on port 1337. I tried to change the above URL to:

http://localhost:1337/socket.io/?__sails_io_sdk_version=0.11.0&__sails_io_s…sails_io_sdk_language=javascript&EIO=3&transport=polling&t=1443472067762-4

and it's working.

In my code I set the URL after sails.io.js has been included:

io.sails.url = 'http://localhost:1337';
io.sails.useCORSRouteToGetCookie = false;

Why is it asking to localhost:8100 and not localhost:1337?

When I launch this application in my mobile device (setting the url to http://192.168.1.10:1337) it's working correctly.

Version of sails.io.js is 0.11.6, and version of sails is 0.11.0

解决方案

I finally found the solution (but I'm sorry I can't recall where I found it :()

The problem was that the io.sails.url = 'http://localhost:1337'; was executed after the first JS cycle, and thus the sails socket was already loaded. (that's (from what I understood) because in some browsers if the code is in another script tag it is executed in another cycle)

To make it work I had to add this code before I include the sails socket script:

var apiHost = 'localhost';
            (function (){
                var io;
                Object.defineProperty(window, 'io', {
                    get: function (){
                        return io;
                    },
                    set: function (value){
                        var sails;
                        io = value;
                        Object.defineProperty(io, 'sails', {
                            get: function (){
                                return sails;
                            },
                            set: function (value){
                                sails = value;
                                sails.url = 'http://'+apiHost+':1337';
                                sails.useCORSRouteToGetCookie = false;
                            }
                        });
                    }
                });
            })();
