java - Cannot make a get request from the back end to google's Query Suggestion Service -

why can't make request end google's query suggestion service using java?

i want make request service google: query suggestion service /suggest protocol.

so can response list suggested queries. seems library front end javascript applications though because there paramater 'client' needs provided. if set chrome , make request via chrome works fine. if try , make request using default in java don't back.

if not possible there other tool similar task?

i had set user-agent same browser using setrequestproperty , worked.
