javacookieshashmapjsoup

I have generated cookies file for Chrome Extension I need to load it in HashMap<String,String> in Java

I have cookies txt file with generated data from Chrome extension is look like this:

# Netscape HTTP Cookie File
# http://curl.haxx.se/rfc/cookie_spec.html
# This is a generated file!  Do not edit.

.site.net   TRUE    /   FALSE   1701453620  _ga GA1.2.10834324067.1638446981
.site.net   TRUE    /   FALSE   1638123020  _gid    GA1.2.25433025264.1638446981
.site.net   TRUE    /   FALSE   1646432624  _fbp    fb.1.1643546988197.973328968

I need to load it to hashmap and to use it in Jsoup connection

 HashMap<String,String> coockies = load.file

 Document doc = Jsoup.connect(mainUrl).cookies(cookies).get();

It is possible to load the txt file and to convert it to hashMap

Solution

  • I would first pre-process the text file to get a key-value list. Something like this:

    grep "^[^#]" cookies.txt | awk '{print $6 " " $7}'

    _ga GA1.2.10834324067.1638446981
_gid GA1.2.25433025264.1638446981
_fbp fb.1.1643546988197.973328968

    The code above strips off lines beginning with a # and empty lines. Next, the result is filtered to only select the 6th (cookie name) and 7th (cookie value) column.

    If you save the output of the above bash command into filtered.txt, you can parse cookie information in Java like so:

    Map<String, String> cookies = new HashMap<>();
try (Stream<String> stream = Files.lines(Paths.get("filtered.txt"))) {
    stream.forEach(line -> {
        String[] columns = line.split(" ");
        cookies.put(columns[0], columns[1]);
    });
}

    We are simply grabbing the key and value from every row to fill our cookies map; I suppose the code could be shorter, however, at the expense of readability.
