大气中的长轮询间隔

Question

大气框架中的长轮询间隔约为60秒。即使在AtmosphereRequest中设置了pollingInterval属性，请求也会在60秒后发送到服务器。如何在请求中设置pollingInterval？这是javascript中的请求: request：{ url : document.location.toString() + 'echo'，

     transport : 'websocket',         fallbackTransport : 'long-polling',         trackMessageLength : true,         reconnect: true,         pollingInterval :10,

     maxReconnectOnClose: Number.MAX\_VALUE,

     reconnectInterval: 10,         connectTimeout: -1 }

Answer 1

在服务器端，在web.xml中，您可以设置以下两个初始参数条目：

 <init-param>
    <param-name>org.atmosphere.cpr.AtmosphereInterceptor</param-name>        
    <param-value>org.atmosphere.interceptor.HeartbeatInterceptor</param-value>
 </init-param>
<init-param>
    <param-name>org.atmosphere.interceptor.HeartbeatInterceptor.heartbeatFrequencyInSeconds</param-name>
    <!-- value in seconds, default 60 -->
    <param-value>10</param-value>
 </init-param>
