http://localhost:8080/api/jsonws

BUILD REQUEST

JSONObject command = new JSONObject(); String method = "/dlapp/add-folder"; JSONObject params = new JSONObject(); params.put("repositoryId", repositoryId); params.put("parentFolderId", parentFolderId); params.put("name", name); params.put("description", description); command.put(method, params);

DefaultHttpClient client = new DefaultHttpClient(); AuthScope authScope = new AuthScope( AuthScope.ANY_HOST, AuthScope.ANY_PORT); Credentials credentials = new UsernamePasswordCredentials( username, password); client.getCredentialsProvider().setCredentials( authScope, credentials);

CONFIGURE HTTP CLIENT

EXECUTE REQUEST

HttpPost post = new HttpPost(url); post.setEntity(new StringEntity(command.toString())); HttpResponse httpResponse = client.execute(post); HttpEntity entity = httpResponse.getEntity(); String response = EntityUtils.toString(entity);

…handle exceptions

WHAT’S NEW?

1. @NNOTATION BASED API2. DEFAULT PARAMETERS3. POJO AUTO PARSING4. REQUEST CANCELATION5. BETTER CONFIGURATION API6. RxJAVA INTEGRATION

@NNOTATION BASED API

CREATING API

public interface GroupService { Call<JsonArray> getUserSites(); }

CREATING API

@Path("/group") public interface GroupService { Call<JsonArray> getUserSites(); }

CREATING API

@Path("/group") public interface GroupService { @Path(“/get-user-sites-groups") Call<JsonArray> getUserSites(); }

CREATING API

@Path("/group") public interface GroupService { @Path(“/get-user-sites-groups") Call<JsonArray> getUserSites();}

INSTANTIATE SERVICE

GroupService service = ServiceBuilder.build( GroupService.class);

INVOKE METHOD

Call<JsonArray> call = service.getUserSites();

JsonArray sites = call.execute();

ASYNC INVOKE METHOD

call.async(new Callback<JsonArray>() { public void onFailure(Exception exception) { } public void onSuccess(JsonArray result) { }

});

PARAMETERS

Call<JsonObject> addFolder( long repositoryId, long parentId, String name, String description);

PARAMETERS

@Path("/add-folder") Call<JsonObject> addFolder( long repositoryId, long parentId, String name, String description);

PARAMETERS

@Path("/add-folder") Call<JsonObject> addFolder( @Param(name = "repositoryId") long repositoryId, @Param(name = "parentFolderId") long parentId, @Param(name = "name") String name, @Param(name = “description”) String description);

PARAMETERS

@Path("/add-folder")Call<JsonObject> addFolder( @Param(name = "repositoryId") long repositoryId, @Param(name = "parentFolderId") long parentId, @Param(name = "name") String name, @Param(name = “description”) String description);

PARAMETERS

@Path("/add-folder") Call<JsonObject> addFolder( @Param(name = "repositoryId") long repositoryId, @Param(name = "parentFolderId") long parentId, @Param(name = "name") String name, @Param(name = “description”) String description);

PARAMETERS

@Path("/add-folder") Call<JsonObject> addFolder( @Param(name = "repositoryId") long repositoryId, @Param(name = "parentFolderId") long parentId, @Param(name = "name") String name);

DEFAULT PARAMETERS

@Path("/add-folder") @Params({ @Param(name = "description", value = "") }) Call<JsonObject> addFolder( @Param(name = "repositoryId") long repositoryId, @Param(name = "parentFolderId") long parentId, @Param(name = "name") String name);

DEFAULT PARAMETERS

@Path("/add-folder")@Params({ @Param(name = "description", value = "") }) Call<JsonObject> addFolder( @Param(name = "repositoryId") long repositoryId, @Param(name = “parentFolderId") long parentId, @Param(name = "name") String name);

POJOAUTO PARSING

POJO AUTO PARSING

public class Site { boolean active; long groupId; String name; String descriptiveName; }

POJO AUTO PARSING

@Path("/group") public interface GroupService { @Path(“/get-user-sites-groups") Call<JsonArray> getUserSites(); }

POJO AUTO PARSING

@Path("/group")public interface GroupService { @Path(“/get-user-sites-groups") Call<JsonArray> getUserSites();}

POJO AUTO PARSING

@Path("/group")public interface GroupService { @Path(“/get-user-sites-groups") Call<List<Site>> getUserSites();}

CANCELLING REQUESTS

CANCEL REQUESTSCall<List<Site>> call = service.getUserSites();

call.async(new Callback<List<Site>>() {

public void onFailure(Exception exception) { } public void onSuccess(List<Site> sites) { } });

Call.cancel(call)

BETTER REQUEST CONFIGURATION

CONFIGURING REQUESTS

Config config = new Config.Builder( “http://localhost:8080”) .auth(new BasicAuthentication("login", "pwd")) .header("headerKey", "headerValue") .timeout(10000) .build(); Config.global(config);

CONFIGURING REQUESTS

Config config = Config.global() .newBuilder() .header("key", "value") .build(); Call<JsonArray> call = service.getUserSites();

JsonArray sites = call.execute(config);

BATCH REQUESTS

BATCH REQUESTS

Call<User> call1 = service.getUserByEmailAddress( 20116, "[email protected]"); Call<User> call2 = service.getUserByEmailAddress( 20116, "[email protected]"); Response response = Batch.execute(call1, call2);

getUserSites() .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(sites -> { }, throwable -> { });
