* 请求 WebAPI的时候，设置有超时时间，比如说3秒超时。（如果3秒之内你不给我数据，我就认为没有数据返回）。
* 在Socket这一端呢，我向Socket发送WebAPI的请求数据。我给WebAPI的请求数据加一个编号，我当然不知道Socket啥时候给我返回数据，所以开了一个异步的线程，只要Socket有返回数据。我就把返回数据存到缓存里（以请求编号为键，缓存数据，这样就可以找到是哪一次请求的数据了，缓存默认30秒过期）。
* 然后WebAPI请求就在主等待返回数据，肯定不能无限期地等待下去，这里有个请求循环，每个循环 之间延迟100毫秒,最多5次循环。在每次循环中，WebAPI请求都是在缓存中找数据，根据请求编号找对应的返回数据，如果找到请求返回的数据，就直接返回。没找到就循环继续找，直到5次循环结束，还没有找到就认为找不到这条数据。
