java - How to set username and password using RESTEasy client builder? -


i have url needs authentication (like browser pop appears asking username , password.)

enter image description here

generally, can use following format achieve this:

http://username:password@url.com

using resteasy client builder 

 client client = clientbuilder.newclient();  webtarget target = client.target("http://url.com");

how achieve without having construct http://username:password@url.com myself? i've seen if there methods use set no luck. i'm not sure how these credentials passed, headers, cookies etc..

looks basic authentication. if that's case, need set authorization header basic base64encode(username:password).

for example:

string credentials = "username:password" string base64encoded = base64.getencoder().encodetostring(credentials.getbytes()); response response = target.request()         .header(httpheaders.authorization, "basic " + base64encoded)....

the base64 class used java 8. if you're not using java 8, there libraries have base64 support. prior java 8, there's com.sun internal base64 class, it's advised not use those.

if want run quick test (and don't have java 8 or don't want go looking lib), can go this site , type in username:password , encode it, copy , paste code.

for example:

base64encode(username:password) == dxnlcm5hbwu6cgfzc3dvcmq=
