如何把一个用户ID 和 一个PID 关联起来。。。

[foxlw66]

是这样的，我想实现一个IM系统。。。

其中我用到了 url?uid=111 这样的形式来传递打开这个页面的是哪个用户

在程序中我是这样接收的。。

Data = Req:parse_qs(),
Uid = list_to_binary(proplists:get_value("uid", Data))
set(Uid,self()); //这是一个朋友提供给我的方法，经测试，编译报错

其实我就是想把这个进程id和一个变量关联起来。。这样等我给他发消息的时候，我就可以利用这个uid

找到这个pid，以便给他能接受到消息，不知erlang中要如何关联呢？？

"This is the case, I would like to achieve an IM system. . .

"Which I use the url? Uid = 111 in such a way to pass to open the page
in which user

"In the program is what I received. .

> Data = Req: parse_qs (),

> Uid = list_to_binary (proplists: get_value ( "uid", Data))

> Set (Uid, self ()); / / This is a friend provided to my method, tested, compiled Baocuo

"In fact, I just want this process id, and a variable associated with
them. . This time I send an announcement to give him the time, I can
take advantage of this uid

"Find the pid, in order to give him to receive messages, I do not know
how associated with it in erlang?
