How can I use persisted cookies from a file using phantomjs

Question

I have some authentication requried to hit a particular url. In browser I need to login only once, as for other related urls which can use the session id from the cookie nee

Answer 1

The file created by the option --cookies-file=cookies.txt is serialized from CookieJar: there are extra characters and it's sometimes difficult to parse.

It may looks like:

[General]
cookies="@Variant(\0\0\0\x7f\0\0\0\x16QList\0\0\0\0\x1\0\0\0\v\0\0\0{__cfduid=da7fda1ef6dd8b38450c6ad5632...

I used in the past phantom.cookies. This array will be pre-populated by any existing Cookie data stored in the cookie file specified in the PhantomJS startup config/command-line options, if any. But you can also add dynamic cookie by using phantom.addCookie.

A basic example is

phantom.addCookie({
    'name':     'Valid-Cookie-Name',   /* required property */
    'value':    'Valid-Cookie-Value',  /* required property */
    'domain':   'localhost',           /* required property */
    'path':     '/foo',
    'httponly': true,
    'secure':   false,
    'expires':  (new Date()).getTime() + (1000 * 60 * 60)   /* <-- expires in 1 hour */
});

With these methods, it's not so difficult to implement your own cookie management logic.
