问题
I have wrote a desktop app, that holds FB applications data and lists test users. I want to open a browser with new profile (browser profile, not FB, because to session problems in PHP facebook API - I want to be not in my a app session on my domain).
But the problem is, that facebook login URL is working or not randomly. I have tried Firefox & Chrome.
Firefox with -no-remote, -p "RANDOM_PROFILE", and also -CreateProfile executing before execution to open url with that profile.
Chrome with --profile-directory="RANDOM_DIR" (directory created earlier).
Managing browser profiles works good in both browser. But in most cases, opening browser with Facebook Test User login URL, just redirects me to main page.
Also, i have created a some PHP pages:
- one redirecting after a while to login URL by window.location
- one redirecting after a sleep by header('Location: ...') to login url
- one with
<a href...>tag to login url.
Third option is the only one working, but it works in about 20% cases (sometimes clicking many times on that link & opening multiple times in new tabs is working)
How to do launch of a new browser instance with facebook login URL where loging works fine ?
Edit: my loging URL's are always fetched from FB very shortly before login try, so they aren't expired.
回答1:
I finally got this.
The problem is, that http://facebook.com must be loaded at least one time (propably for setting some cookies) before using Test User login URL.
So, i use a script to open the Facebook in iframe, and then after some time redirects to login url:
<script>
setTimeout(function(){
window.location = "<?php echo $_GET['url']; ?>";
} , 2000 );
</script>
<iframe src="http://facebook.com/"></iframe>
Notice that facebook on iframe will load as head+body only blank page, but this is working.
Then you can use this script to login Test User by passing it to Chrome command line, with url-encoded Test-User-Login-URL as 'url' GET parameter.
Use fresh created directory for chrome profile to avoid getting old session on your app domain.
Also, I suggest using arguments: --start-maximized, --no-default-browser-check, --no-first-run
UPDATE: Notice that requested login URL will work only once with this method (and maybe any other methods - didn't checked)
