REST service for Janet. Supports fully customizable requests, http-clients and converters.

ActionService httpService = new HttpActionService(API_URL, new OkClient(), new GsonConverter(new Gson()))
Janet janet = new Janet.Builder().addService(httpService).build();

Service requires: End-point url, HttpClient and Converter.

@HttpAction(value = "/demo", method = HttpAction.Method.GET)
public class ExampleAction {
  @Response ExampleDataModel responseData;
}

Each action is an individual class that contains all information about the request and response. It must be annotated with @HttpAction

ActionPipe<ExampleAction> actionPipe = janet.createPipe(ExampleAction.class);
actionPipe
  .createObservable(new ExampleAction())
  .subscribeOn(Schedulers.io())
  .subscribe(new ActionStateSubscriber<ExampleAction>()
          .onProgress((action, progress) -> System.out.println("Current progress: " + progress))
          .onSuccess(action -> System.out.println("Got example " + action))
          .onFail((action, throwable) -> System.err.println("Bad things happened " + throwable))
  );

Request path, method and type are defined by @HttpAction annotation:

• value – url path
• method – get/post/put/delete/head/patch
• type –  simple/multipart/form_url_encoded

To configure request, Action fields can be annotated with:

• @Path for path value
• @Url rewrites full url or suffixes
• @Query for request URL parameters
• @Body for POST request body
• @Field for request fields if request type is HttpAction.Type.FORM_URL_ENCODED
• @Part for multipart request parts
• @RequestHeader for request headers

To process response, special annotations can be used:

• @Response for getting response body.
• @Status for getting response status. Field types Integer, Long, int or long can be used to get status code or use boolean to know that request was sent successfully
• @ResponseHeader for getting response headers

Example:

@HttpAction(
        value = "/demo/{examplePath}/info",
        method = HttpAction.Method.GET,
        type = HttpAction.Type.SIMPLE
)
public class ExampleAction {
    // Request params
    @Path("examplePath") String pathValue;
    @Query("someParam") int queryParam;
    @RequestHeader("Example-RequestHeader-Name") String requestHeaderValue;
    // Response data
    @Status int statusCode;
    @Response ExampleDataModel exampleDataModel;
    @ResponseHeader("Example-ResponseHeader-Name") String responseHeaderValue;
}

• supports request progress;
• supports request cancelation;
• provides useful HttpException for failed requests;
• supports action inheritance
• based on annotation processing
• consider using javac option '-Ajanet.http.factory.class.suffix=MyLib' for api libraries

Kotlin action classes are supported except internal modifier. See UsersAction as example.

• janet-http:
• janet-converters:

• Authorize requests via ActionServiceWrapper, e.g. AuthWrapper
• Log requests via HttpClient or ActionServiceWrapper, e.g. SampleLoggingService
• Convert Retrofit interfaces into actions with Converter Util
• Write tests using MockHttpActionService
• See more samples: Simple Android app, Advanced Android app

• Add Rules to your proguard config.
• See Android Sample for complete proguard config example.

HttpActionService is highly inspired by Retrofit2 – thanks guys, it's awesome! We put our effort to make it even more flexible and reusable, so everyone who loves Retrofit and reactive approach should give it a try.
