nscjar

nscjar is a small golang package used to parse and output Netscape/Mozilla's old-school cookie files. It also implements a simple cookie jar struct to manage the cookies added to the cookie jar.

Usage

Parser

The usage is simple. The cookie data file has a simple format.

DOMAIN    FLAGS    PATH     SECURE     EXPIRY_TIMESTAMP     NAME      VALUE
some.com   TRUE     /        TRUE         15333423          lang      en_US

Parsing this in go is simple.

    jar := nscjar.Parser{}
    cookies, err := jar.Unmarshal(f)            // f : io.Reader
    ...handle error...

And writing back to file is very simple too :

    jar := nscjar.Parser{}
    jar.Marshal(w, c)          // w : io.Writer, c : http.Cookie

See the test.go file for the usage.

Cookie Jar

The cookie jar is used to manage the cookie data added to the struct. Usage is simple. Say you have a HTTP Response object (r := http.Response{}).

    jar := nscjar.NewCookieJar()
    jar.AddCookies(r.Cookies())          // To add multiple *http.Cookie at the same time.

    // Unmarshalling it to a Netscape Cookie file format is easy.
    f, _ := os.OpenFile("cookie.txt", os.O_CREATE|os.O_RDWR, 0666)
    // please do the error checks.
    jar.Marshal(f) // any io.Writer will do. This returns an error.
