Use HttpClient to create a request with a cookie and transfer form form

Used in the project, need to use httpclient to simulate form transfer form form requirements, in ordinary projects, probably is to send JSON string style requirements, but how to send a form form to the corresponding server?

This requires the namevaluepair of the method, you can do form form data transmission, I recorded here

　　　　1. You need to define a collection of Namevaluepair, the elements of this set that are placed in our form form

New Arraylist<>();
Put our form element Pair.add (new basicnamevaluepair ("Licenseno", Licenseno));          Pair.add (new Basicnamevaluepair ("token", token));          Pair.add (new basicnamevaluepair ("City");          Pair.add (new basicnamevaluepair ("timestamp", timestamp));          Pair.add (new basicnamevaluepair ("sign", sign));

2. Use HttpClient in setentity (new urlencodedformentity (pair, HTTP. utf_8)) data transfer is OK.
