谁能给我一个简单的使用 PHP 的彗星技术示例?
Can anyone give me a good and simple example of the comet technique using PHP?
我只需要一个使用持久 HTTP 连接或类似内容的示例.我不想使用轮询技术,因为我有类似的设置,不仅难以使用和管理它的大量资源.另外我使用的是 IIS7 而不是 Apache.
I just need an example that uses a persistent HTTP connection or something similar. I don't want to use a polling technique, because I have something like that set up and not only is it difficult to work with and manage its a big hog of resources. Also I am using IIS7 not Apache.
一个很好的例子会很有帮助,这样我就可以继续使用这种丑陋的投票技术.
A good example would be really helpful so I can move on from this ugly polling technique.
你应该使用轮询,或者使用一个专门为长请求和 COMET 设计的 web 服务器,有一个好的 JS 后端:
You should use polling, or use a web server which is specially conceived for long requests and COMET, with a good JS backend:
function listen() {
$.get("/mylongrequestfile", {}, function(data) {
$("#mydiv").html(data);
listen(); // then launch again
}));
};
记住COMET是等待数据,有数据返回退出",所以JS后端要解析数据,重新启动询问服务器的过程.
Remember that COMET is "wait for data, if there's data return and exit", so JS backend will have to parse the data and re-launch the process of asking the server.
在这个例子中,如果出现服务器端问题或者只是与用户端断开连接,整个过程都会被破坏(只有请求成功才会调用该函数)
In this example, if there is a server side problem or just a disconnection from the user side, the entire process will be broken (the function is only called if the request is successful)
这篇关于使用 php 和 jquery 的简单彗星示例的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持html5模板网!
