My Two cents.

IN JAVASCRIPT

<a href="http://jsfiddle.net/eSQ2X/" rel="nofollow">FIDDLE DEMO</a>

<pre><code>var req = new XMLHttpRequest();
req.open('GET', document.location, false);
req.send(null);
var headers = req.getAllResponseHeaders().toLowerCase();
console.log(headers);
alert(headers)
</code></pre>

IN PHP

<pre><code>&lt;?php echo $_SERVER["HTTP_REFERER"]; ?&gt;
</code></pre>

blocks|key|2462830|text|我从来没有使用过一次获得所有它们的方法，但您应该能够按照您正在做的方式单独获取它们。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2462831|我也为推荐人尝试过，但它不起作用，但我发现如果你这样做了：|2462832|+httpChannel.referrer.host+|code-block|syntax|javascript|2462833|(referrer有两个r)，它显示referer的地址。|2462834|另外，你可能想看看httpfox的源代码，它做了你想做的事情。|offset|length|2462835|您可以在以下链接中找到其他帮助：nsITraceableChannel,+Intercept+HTTP+Traffic+%7C+Software+is+hard|2462836|还有这个：Howto:+XHR+Listening+by+a+Firefox+Addon|2462837|entityMap|0|LINK|mutability|MUTABLE|url|https://addons.mozilla.org/en-us/firefox/addon/httpfox/|1|http://www.softwareishard.com/blog/firebug/nsitraceablechannel-intercept-http-traffic/|2|http://www.ashita.org/howto-xhr-listening-by-a-firefox-addon/^0|0|0|0|0|9|7|0|0|G|1Q|1|0|5|13|2|0^^$0|@$1|2|3|4|5|6|7|14|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|15|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|16|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|17|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|18|8|@]|9|@$M|19|N|1A|1|1B]]|A|$]]|$1|O|3|P|5|6|7|1C|8|@]|9|@$M|1D|N|1E|1|1F]]|A|$]]|$1|Q|3|R|5|6|7|1G|8|@]|9|@$M|1H|N|1I|1|1J]]|A|$]]|$1|S|3|-4|5|6|7|1K|8|@]|9|@]|A|$]]]|T|$U|$5|V|W|X|A|$Y|Z]]|10|$5|V|W|X|A|$Y|11]]|12|$5|V|W|X|A|$Y|13]]]]

I never used a way of getting them all at once, but you should be able to get them individually with the way you are doing. 

I tried it too for the referer, but it didn't work, but i found that if you do:

<pre><code> httpChannel.referrer.host 
</code></pre>

(referrer has two r's), it shows the address of the referer. 

Additionally, you might want to take a look at the source code of <a href="https://addons.mozilla.org/en-us/firefox/addon/httpfox/" rel="nofollow">httpfox</a>, it does what you are trying to do.

You might find additional help in this link: <a href="http://www.softwareishard.com/blog/firebug/nsitraceablechannel-intercept-http-traffic/" rel="nofollow">nsITraceableChannel, Intercept HTTP Traffic | Software is hard</a>

Your observe function should look like this:

<pre><code>observe: function(subject, topic, data) {

 if (topic === "http-on-modify-request") {

 var channel = subject.QueryInterface(Components.interfaces.nsIHttpChannel);
 alert("URI: " + channel.URI.asciiSpec);

 channel.visitRequestHeaders(function(name, value) {

 // do something with each header
 if (name === 'User-Agent') {

 alert(name+': '+value);
 }
 });
 }
},
</code></pre>

I want to get the complete information of a http header when a http request has made by using http-on-modify-request.

Example of the information i want to get:

<img src="https://i.stack.imgur.com/03Bpa.png" alt="enter image description here">

i have this code:

<pre><code>myObserver.prototype = {
 observe: function(subject, topic, data) {

 if("http-on-modify-request"){
 var httpChannel = 
 subject.QueryInterface(Components.interfaces.nsIHttpChannel);
 alert("URI: " + httpChannel.originalURI.spec);
 alert("User-Agent: " + httpChannel.getRequestHeader('user-agent'));
 }

},
 register: function() {
var observerService = Components.classes["@mozilla.org/observer-service;1"]
 .getService(Components.interfaces.nsIObserverService);
observerService.addObserver(this, "http-on-modify-request", false);
 },
unregister: function() {
var observerService = Components.classes["@mozilla.org/observer-service;1"]
 .getService(Components.interfaces.nsIObserverService);
observerService.removeObserver(this, "http-on-modify-request");
 }
}
</code></pre>
