How do i get parameter value from url as string

Question

I have one request which response is displayed as url below. I need to extract user_token value from url and pass to subsequent request. response url: http://example.com?user_token=0c1c59bc-3aaa-40f1-b978-7172de09a27f&m_id=9999&code=200&is_register=false&M=SUCCESS

i want to extract user_token from it and want to pass it to subsequent request, need solution in java code not java script.

It is unclear what you are talking about. Do you want to extract the token from the url-String or do you want an endpoint that can use the query parameter? — Turing85, Aug 07 '20 at 20:05

You can do this:

String getTokenId(String url){

String[] splitUrl = url.split("user_token=");
String tokenId = "";

if(splitUrl.length >1){

for(int i =0; i < splitUrl[1].length(); i++){
    if(splitUrl[1].charAt(i) == '&'){
        tokenId = splitUrl[1].substring(0,i);
        break;
    }
}

}

return  tokenId;
}

But if you know the exact length of the token, it could be a search.

Maybe what you need is request.getParameter("user_token"). You can do this in servlet for example

Note, that request is a parameter of a servlet method like doGet or doPost – Aug 07 '20 at 20:18
