Socket.io从php源 [英] Socket.io from php source

问题描述

我已经通过使用 socket.io 开发了一个客户端 - 服务器连接，我很高兴地说，它工作完美。
问题出现，因为我需要从php源（不是echo html javascript）创建该连接。像

  $ socket = socket.createConectionJS; 
  

我尝试了不同的方法，例如：

• 从服务器（使用spiderMonkey和节点）

执行代码创建一个phpSocket并将其连接到ServerSocket.j格式不同）。或...

• 最后，我已经尝试通过curl，我可以访问serverscript，但我无法打开连接

我认为解决它的唯一方法是模拟web套接字连接创建一个套接字与de socket.io类做同样的方式，但在php

Anny socket.io专家可以帮助？

Tnks！ ！ _

解决方案

是啊，我很幸运有一个相当高级的网络抓取库已经内置在PHP，所以我只是插入来自TamperData（firefox插件）的XML，并调整了几件事。

要模拟xhr-polling（我的代理不允许websockets，这看起来更简单了）...

请求：

  /socket.io/1/?t=1337779479761 
  

（13377 ...数字只是一个时间戳，使用time（）生成它）。

像这样：

  682970926640665221：60：60：websocket，htmlfile，xhr-polling，jsonp-polling 
  

抓住前面的大数字，这是你的[CONNECT_ID]，会话。现在再执行一个请求：

  /socket.io/1/xhr-polling/ [CONNECT_ID]？t = [TIMESTAMP] 
  

你会得到类似:: 1的

$ b b

这是关于我打算跟着它，这一切看起来相当基本从那里...没有特殊的标题或任何鬼祟。建议你使用TamperData或数据包嗅探器，只是自己跟着它。这是我的代码的输出：

  $ php RealTestCurl.php xml / xhr.xml init1 xhr1 xhr1 xhr1 xhr1 
 
 xmlFilename：xml / xhr.xml 
 
步骤：init1 
回复：7638339571841585529：60：60：websocket，htmlfile，xhr-polling，jsonp-polling 
找到：connect_id：（[0-9] *） -  7638339571841585529 
 
步骤：xhr1 
回复：1 :: 
 
步骤：xhr1 
 ：？46？5 ::: {name：news，args：[{hello：world}] args：[{will：will received by everyone}]} 
 
步骤：xhr1 
 ....这里有一个巨大的20秒超时

在node.js / socket.io端，从头开始运行基本示例：

  debug  -  client authorized

 debug  - 设置请求GET /socket.io/1/xhr-polling/3445861131360107212?t=1337781185 
 debug - 设置轮询超时
 debug  - 客户机授权
 debug  - 清除轮询超时
 debug  -  xhr-polling writing 1 :: 
 debug  - 设置客户机的关闭超时3445861131360107212 
 debug  -  websocket writing 5 ::: {name：this，args：[{will：will received by everyone}]}

I have developed a client-server connection by using socket.io, and i'm happy to say that it works perfectly. 
The problem comes because I need to create that connection from php Source ( not "echo   html javascript"  ). Something Like a 
$socket = socket.createConectionJS;
I've tried difrerent ways, such as : 


execute the code from the server ( with spiderMonkey, and node ) 
creating a phpSocket and connecting it to the ServerSocket.j( but obbiously the format is diferent). or ...
Finally i've tried by post with curl, where I had access to the serverscript, but i can't open a connection


I'm thinking the only way to resolve it is simulating the web socket connection by creating a socket with the same way as de socket.io class do it but in php 

Anny socket.io expert could help ?

解决方案
Yeah, I had a quick go at it just then.  I'm fortunate to have a fairly advanced web scraping library already built in PHP, so I just plugged the XML from TamperData (firefox plugin), into it, and tweaked a few things.

To emulate xhr-polling (my proxy doesn't allow websockets, and this looked simpler anyway)... 

Make a request to:
/socket.io/1/?t=1337779479761   
(The 13377... number is just a timestamp, use time() to generate it).

That should return something like this:
682970926640665221:60:60:websocket,htmlfile,xhr-polling,jsonp-polling
Grab the big number at the front out, that's your "[CONNECT_ID]", which you'll keep for the remainder of the session.  Now do another request:
/socket.io/1/xhr-polling/[CONNECT_ID]?t=[TIMESTAMP]
And you'll get back something like ::1   

That's about as far as I bothered to follow it, it all looked fairly basic from there... no special headers or anything sneaky. Suggest you use TamperData or a packet sniffer, and just follow it yourself.  Here was the output from my code:
$ php RealTestCurl.php xml/xhr.xml init1 xhr1 xhr1 xhr1 xhr1

xmlFilename: xml/xhr.xml

Step: init1

And on the node.js/socket.io side, running on of the basic examples from their front page:
debug - client authorized
info  - handshake authorized 3445861131360107212
debug - setting request GET /socket.io/1/xhr-polling/3445861131360107212?t=1337781185
debug - setting poll timeout

debug - websocket writing 5:::{"name":"this","args":[{"will":"be received by everyone"}]}
