Java calls RESTful WebService (RPM)

In general, you will only use the Get and post methods to invoke.

• Get method, parameters can be written in the URL.

For example, the server's interface with the @requestparam or @pathvariable, in the client call, can be directly written in the URL, the specific wording I will not write, and the following similar.

• Post method. This is a bit different, and the parameters are written in the body of the request, not inside the URL.

url = url = new URL (http://test.webservice.api/test);

HttpURLConnection connection = (httpurlconnection) url.openconnection ();

Connection.setdooutput (TRUE);

Connection.setdoinput (TRUE);

Connection.setrequestmethod ("POST");

Connection.setusecaches (FALSE);

Connection.setrequestproperty ("Accept-charset", "UTF-8");

Connection.setrequestproperty ("Expect", "100-continue");

...

DataOutputStream WR = new DataOutputStream ();
Wr.writebytes ("parameter=xxx¶meter2=yyy");

Wr.flush ();

Wr.close ();.
