Reading browser cookies in safari extension - safari-extension

Question

I am new to safari extension development. I need to access browser cookies specific to a web site. I know that this is possible with in chrome extension development. How can do this with safari extension development.

Answer 1

From an injected script you can send the cookies to the extension. So when building the extension you have global.html and injected.js.
injected.js:
var cookies = document.cookie;
safari.self.tab.dispatchMessage("setCookies",cookies);
global.html (without the HTML tags):
var cookies = null;
function getCookies(incMsg) {
cookies = incMsg.message;
alert('I received them :) \n\n'+cookies);
}
safari.application.addEventListener("message",getCookies,false);
The code above will send all the cookies to the extension each time you load a page. Then of course you still need to read out the cookies. I used something like the following function (in global.html):
function readCookie(name) {
if(cookies) {
var nameEQ = name + "=";
var ca = cookies.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
}
Good luck!
