Lua 电晕客户端，我收到无限的信息

我在Corona SDK上开发了客户端，但我有一个问题： 我可以连接到服务器并从服务器接收第一条消息。我也可以给你回信。但之后我开始接收空字符串。我怀疑我的客户端代码每次都读取“\0”字符，但我不确定。这是我的客户代码：

（服务器每5秒钟发送一条消息“{id=1000}”）

我改变了阅读习惯，效果很好。答案如下：

        for i,v in ipairs(input) do  -------------

            local got_something_new = false
            while  true  do
                skt, e, p = v:receive(1)
                if skt      then
                    if skt ~= '\0' then
                        self.buffer = self.buffer..skt  
                    else
                        got_something_new = true
                        self.buffer = "__JSON__START__"..self.buffer.."__JSON__END__"
                    end
                end
                if p        then 
                    if p ~= '\0' then
                        self.buffer = self.buffer..p;
                    else
                        got_something_new = true
                        self.buffer = "__JSON__START__"..self.buffer.."__JSON__END__"
                    end
                end
                if not skt  then break; end
                if e        then print( "ERROR: ", e ); break; end
            end

            -- now, checking if a message is present in buffer...
            while got_something_new do  --  this is for a case of several messages stocker in the buffer
                local start = string.find(self.buffer,'__JSON__START__')
                local finish = string.find(self.buffer,'__JSON__END__')
                if (start and finish) then -- found a message!
                    local message = string.sub( self.buffer, start+15, finish-1)
                    self.buffer = string.sub( self.buffer, 1, start-1 )  ..   string.sub(self.buffer, finish + 13 ) -- cutting our message from buffer
                    self.callback(  message  )
                else
                    break
                end
            end
        end         

        for i,v in ipairs(input) do  -------------

            local got_something_new = false
            while  true  do
                skt, e, p = v:receive(1)
                if skt      then
                    if skt ~= '\0' then
                        self.buffer = self.buffer..skt  
                    else
                        got_something_new = true
                        self.buffer = "__JSON__START__"..self.buffer.."__JSON__END__"
                    end
                end
                if p        then 
                    if p ~= '\0' then
                        self.buffer = self.buffer..p;

            -- now, checking if a message is present in buffer...

                    self.callback(  message  )
                else
                    break
                end
            end
        end
