The Mozilla Developer Center cookies examples were very close to what I needed. nsICookieManager.remove seemed perfect. In a FireWatir script it looked like what I needed to read/write cookies was something like this:
def removeCookie(brwsr, host, name, path)
cmd = "Components.classes['@mozilla.org/cookiemanager;1']"
cmd += ".getService(Components.interfaces.nsICookieManager)"
cmd += ".remove(\"" + host + "\", \"" + name + "\", \"" + path + "\", false)";
puts "Removing cookie " + name + " from " + host + " for path " + path
result = brwsr.execute_script "#{cmd}\n"
end
def readCookies(brwsr, site)
cmd = "var uri = Components.classes['@mozilla.org/network/io-service;1'].getService(Components.interfaces.nsIIOService)"
cmd += ".newURI(\"" + site + "\", null, null);"
cmd += "Components.classes['@mozilla.org/cookieService;1']"
cmd += ".getService(Components.interfaces.nsICookieService)"
cmd += ".getCookieString(uri, null);"
result = brwsr.execute_script "#{cmd}\n"
end
In my initial attempts to use this I passed in "http://myhost" and although the method succeeded subsequent logging of the updated cookie string showed no change at all. After some fumbling around I discovered a detailed example of manipulating cookies through javascript in an extension. The main difference in their example was no protocol:// in front of the host/domain name. After that it worked perfectly. A simple example follows:
require "watir"
protocol = "http";
host = "mytesthost";
initial_path = "/somethingfuntotest"
site = protocol + "://" + host
def url(brwsr)
return brwsr.js_eval("document.location.toString();")
end
def readCookies(brwsr, site)
cmd = "var uri = Components.classes['@mozilla.org/network/io-service;1'].getService(Components.interfaces.nsIIOService)"
cmd += ".newURI(\"" + site + "\", null, null);"
cmd += "Components.classes['@mozilla.org/cookieService;1']"
cmd += ".getService(Components.interfaces.nsICookieService)"
cmd += ".getCookieString(uri, null);"
result = brwsr.execute_script "#{cmd}\n"
end

#Usage removeCookie(brwsr, "myhostname", "SessionIdCookieName", "/")
#Note that passing http://myhostname for host does not appear to work
def removeCookie(brwsr, host, name, path)
cmd = "Components.classes['@mozilla.org/cookiemanager;1']"
cmd += ".getService(Components.interfaces.nsICookieManager)"
cmd += ".remove(\"" + host + "\", \"" + name + "\", \"" + path + "\", false)";
puts "Removing cookie " + name + " from " + host + " for path " + path
result = brwsr.execute_script "#{cmd}\n"
end
Watir::Browser.default = "firefox"
brwsr = Watir::Browser.new
#May have a session id
puts "Cookies for " + site + ": " + readCookies(brwsr, site)
removeCookie(brwsr, host, "JSESSIONID", "/")
#Session id is now gone ... yay!
puts "Cookies for " + site + ": " + readCookies(brwsr, site)
