我开始说这在我的本地机器上完美运行,下面的js示例连接到stream.PHP并且每秒接收服务器当前时间的连续更新.
@H_502_1@的index.PHP
var source = new EventSource("stream.PHP");
source.addEventListener('message',function(e) {
console.log(e);
},false);
source.addEventListener('open',false);
source.addEventListener('error',function(e) {
if (e.readyState == EventSource.CLOSED) {
console.log('closed');
}
},false);
@H_502_1@stream.PHP
while(true)
{
// Headers must be processed line by line.
header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');
// Set data line
print "data: " . date( 'G:H:s',time() ) . PHP_EOL . PHP_EOL;
// Toilet
flush();
// Wait one second.
sleep(1);
}
@H_502_1@上传到live dev之后我确实预计会有一点延迟.服务器.但是有大约15到20分钟的时间延迟.在我看到第一个条目之前.
@H_502_1@连接不会丢失. (问题.现在已经过了40分钟.)这只是一个Apache循环问题(意味着是时候看看网络套接字了)还是我可以做些什么来解决这个问题？
Server.PHP需要如下：
@H_502_1@stream.PHP
while(true)
{
// Headers must be processed line by line.
header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');
// Set data line
print "Event: server-time" . PHP_EOL;
print "data: " . date( 'G:H:s',time() ) . PHP_EOL;
print PHP_EOL;
ob_end_flush(); // Strange behavIoUr,will not work
flush(); // Unless both are called !
// Wait one second.
sleep(1);
}
