socket.io客户端重新连接超时(socket.io client reconnect timeout)

 我使用socket.io和node.js，我喜欢这个解决方案。 我注意到的唯一问题是断开连接和重新连接。  
 这些是我目前的设置：  
  'connect timeout': 1000,
  'reconnect': true,
  'reconnection delay': 300,
  'max reconnection attempts': 10000,
  'force new connection':true
 
 我注意到，如果我停下来并启动node.js进程，客户端将连接正常并且很快，但是如果服务器处于脱机状态几分钟，则客户端不会重新连接或需要很长时间（非用户友好）时间至。  
 我想问问是否有任何我错过了或可能添加到socket.io配置，以保持客户端轮询重新连接。  
 我知道'重新连接延迟'：  
 
  重新连接延迟默认为500毫秒  
  启动重新连接的初始超时，每次进行新的重新连接尝试时都会使用指数退避算法来增加。  
 
 但指数效应对用户不太友好。 是否有一种方法可以每隔X个时间周期检查一次连接 - 例如：5秒。  
 如果没有，我想我可以写一些客户端JS来检查连接并尝试重新连接，如果需要的话，但它会很好，如果socket.io客户端提供了这一点。  
 谢谢 

I'm using socket.io with node.js and I like the solution. The only issue I notice is around a disconnection and reconnection. 
These are my current settings: 
  'connect timeout': 1000,
  'reconnect': true,
  'reconnection delay': 300,
  'max reconnection attempts': 10000,
  'force new connection':true
 
I notice if I stop and start the node.js process the client connects back fine and quickly, however if the server is offline for a couple of minutes the client either never reconnects or takes a very long (non-user friendly) amount of time to. 
I wanted to ask if there is anything I've missed or could add to the socket.io configuration to keep the client polling for a reconnection. 
I know 'reconnection delay': 
 
 reconnection delay defaults to 500 ms 
 The initial timeout to start a reconnect, this is increased using an exponential back off algorithm each time a new reconnection attempt has been made. 
 
But the exponential effect its not very user friendly. Is there a way to keep checking for a connection every X period of time - eg: 5 seconds. 
If not I guess I can write some client side JS to check the connect and attempt reconnections if needed but it would be nice if the socket.io client offered this. 
thx

 不知何故，我怀疑你的驱动程序是否支持FrameBufferObject扩展，如果它不提供着色器但它值得一试。 那么这不是你想要的，你可能不得不首先使用glTexEnv或稍微聪明一点然后我，但是它应用了一个掩码和图像，但实际上并没有添加alpha值：  
import pyglet
from pyglet.gl import *

window = pyglet.window.Window()
image = pyglet.resource.image('pic.jpg')
mask = pyglet.resource.image('mask.jpg')
createdtex=False;
imagetex = 0


@window.event
def on_draw():
    window.clear()
    global createdtex
    texfrmbuf =(GLuint*1)()
    global imagetex
    if createdtex!=True:
        imagetex = image.get_texture()
        glEnable(GL_BLEND)
        glBlendFunc(GL_ZERO, GL_SRC_COLOR)
        glGenFramebuffersEXT(1,texfrmbuf)
        glBindFramebufferEXT(GL_DRAW_FRAMEBUFFER_EXT,texfrmbuf[0])
        glFramebufferTexture2DEXT(GL_DRAW_FRAMEBUFFER_EXT,GL_COLOR_ATTACHMENT0_EXT, imagetex.target,imagetex.id,0)
        mask.blit(0,0)
        glFlush()
        glDisable(GL_BLEND)
        glDeleteFramebuffersEXT(1,texfrmbuf)
        glBindFramebufferEXT(GL_DRAW_FRAMEBUFFER_EXT,0)
        createdtex=True

    imagetex.blit(0,0)

pyglet.app.run()

Somehow I doubt that your driver supports the FrameBufferObject extension if it doesn't provide shaders but it's worth a shot. Well this isn't quite what you want so, you'll probably have to use glTexEnv after all or be a little more clever about it then me but this applies a mask to and image but doesn't actually add the alpha value: 
import pyglet
from pyglet.gl import *

window = pyglet.window.Window()
image = pyglet.resource.image('pic.jpg')
mask = pyglet.resource.image('mask.jpg')
createdtex=False;
imagetex = 0


@window.event
def on_draw():
    window.clear()
    global createdtex
    texfrmbuf =(GLuint*1)()
    global imagetex
    if createdtex!=True:
        imagetex = image.get_texture()
        glEnable(GL_BLEND)
        glBlendFunc(GL_ZERO, GL_SRC_COLOR)
        glGenFramebuffersEXT(1,texfrmbuf)
        glBindFramebufferEXT(GL_DRAW_FRAMEBUFFER_EXT,texfrmbuf[0])
        glFramebufferTexture2DEXT(GL_DRAW_FRAMEBUFFER_EXT,GL_COLOR_ATTACHMENT0_EXT, imagetex.target,imagetex.id,0)
        mask.blit(0,0)
        glFlush()
        glDisable(GL_BLEND)
        glDeleteFramebuffersEXT(1,texfrmbuf)
        glBindFramebufferEXT(GL_DRAW_FRAMEBUFFER_EXT,0)
        createdtex=True

    imagetex.blit(0,0)

pyglet.app.run()
