android - Whats wrong with this retrofit call? -
im trying send post , build response using retrofit android.
i have managed send no problems need send post body elements.
public static <s> s createaccessservice(class<s> serviceclass, string code, string redirecturi, string clientid, string clientsecret) { okhttpclient.builder httpclient = new okhttpclient.builder(); string basiccredentials = clientid+":"+clientsecret; byte[] encodebytes = base64.encode(basiccredentials.getbytes(), base64.no_wrap); httpclient.addinterceptor(new interceptor() { @override public response intercept(chain chain) throws ioexception { request original = chain.request(); requestbody body = new formbody.builder() .add("grant_type", "authorization_code") .add("code", code) .add("redirect_uri", redirecturi).build(); request request = original.newbuilder() .addheader("authorization", "basic "+new string(encodebytes)) .method(original.method(), original.body()) .put(body) .build(); return chain.proceed(request); } }); okhttpclient client = httpclient.build(); retrofit retrofit = new retrofit.builder() .baseurl(api_base_url) .addconverterfactory(gsonconverterfactory.create()) .client(client) .build(); return retrofit.create(serviceclass); the post i'm trying build looks one:
post /api/token http/1.1 host: accounts.spotify.com authorization: basic *********************************** cache-control: no-cache postman-token: 99177da6-1606-3145-689d-bc4b09b3f212 content-type: application/x-www-form-urlencoded grant_type=authorization_code&redirect_uri=http%3a%2f%2flocalhost%3a8888%2fcallback&code********************************************************************************************************************************************************* obviously keys hidden security.
and pojo im using store response.
public class session { private string scope; private string expires_in; private string token_type; private string refresh_token; private string access_token; private string error; public string geterror_description() { return error_description; } public void seterror_description(string error_description) { this.error_description = error_description; } public string geterror() { return error; } public void seterror(string error) { this.error = error; } private string error_description; public string getscope () { return scope; } public void setscope (string scope) { this.scope = scope; } public string getexpires_in () { return expires_in; } public void setexpires_in (string expires_in) { this.expires_in = expires_in; } public string gettoken_type () { return token_type; } public void settoken_type (string token_type) { this.token_type = token_type; } public string getrefresh_token () { return refresh_token; } public void setrefresh_token (string refresh_token) { this.refresh_token = refresh_token; } public string getaccess_token () { return access_token; } public void setaccess_token (string access_token) { this.access_token = access_token; } } i have changed lot of things no matter what, response cannot instanciate new session object, returning null always.
added:
this interface im using:
@formurlencoded @post("/api/token") call<session> getsession(); what doing wrong?
thanks
well, if try send post request retrofit2, should try this:
first, create interface, in interface declare body contents post request:
public interface isesion { @formurlencoded @post("/users/login") call<sesion> insesion(@field("username") string usuario, @field("password") string password); } the parameter @field body content use in post request
now, can make in mainactivity:
public class mainactivity extends appcompatactivity { private retrofit retrofit; //your retrofit object private isesion isesion; //your interface @override protected void oncreate(bundle savedinstancestate) { retrofit = new retrofit.builder() .baseurl(getstring(r.string.url_base)) //your base url ("http://www.myexample.com") .addconverterfactory(gsonconverterfactory.create()) .build(); isesion = retrofit.create(isesion.class); call<sesion> call = isesion.insesion(usuario, contrasena); //you fields edittext, example, , pass method in interface call.enqueue(new callback<sesion>() { @override public void onresponse(call<sesion> call, response<sesion> response) { code = response.code(); switch (code) { case 200: intent intent = new intent(getactivity(), mainactivity.class); intent.setflags(intent.flag_activity_new_task | intent.flag_activity_clear_task); startactivity(intent); break; case 401: error = response.body().iserror(); mensaje = response.body().getmensaje(); if (error) { snackbar.make(view, mensaje, snackbar.length_long).show(); } break; } } @override public void onfailure(call<sesion> call, throwable t) { t.printstacktrace(); snackbar.make(view, getstring(r.string.error_general), snackbar.length_long).show(); } }); } } the model used in method call<sesion> next:
public class sesion { @serializedname("error") private boolean error; @serializedname("message") private string mensaje; public boolean iserror() { return error; } public string getmensaje() { return mensaje; } } edit:
if want send token in body content couldtry this:
call<sesion> call = isesion.insesion("basic " + generatedtoken); // here authentication token call.enqueue(new callback<sesion>() { @override public void onresponse(call<sesion> call, response<sesion> response) { code = response.code(); switch (code) { case 200: intent intent = new intent(getactivity(), mainactivity.class); intent.setflags(intent.flag_activity_new_task | intent.flag_activity_clear_task); startactivity(intent); break; case 401: error = response.body().iserror(); mensaje = response.body().getmensaje(); if (error) { snackbar.make(view, mensaje, snackbar.length_long).show(); } break; } } @override public void onfailure(call<sesion> call, throwable t) { t.printstacktrace(); snackbar.make(view, getstring(r.string.error_general), snackbar.length_long).show(); } }); } and interface:
public interface isesion { @formurlencoded @post("/users/login") call<sesion> insesion(@field("token") string generatedtoken); }
