Retrofit2

Every method of an interface represents one possible API call. The return value wraps the response in a Call retrofit2 with the type of the expected result, retrofit2. You can use replacement blocks and query parameters to adjust the URL, retrofit2.

A Retrofit 2 Converter. Factory for Kotlin serialization. Add a converter factory when building your Retrofit instance using the asConverterFactory extension function:. Response body types e. Because Kotlin serialization is so flexible in the types it supports, these converters assume that they can handle all types. If you are mixing this converter with another, you must add this instance last to allow the other converters a chance to see their types. Snapshots of the development version are available in Sonatype's snapshots repository.

The Retrofit class generates an implementation of the GitHubService interface. The relative URL of the resource is specified in the annotation. A request URL can be updated dynamically using replacement blocks and parameters on the method. A corresponding parameter must be annotated with Path using the same string. The object will also be converted using a converter specified on the Retrofit instance.

Every method of an interface represents one possible API call. The return value wraps the response in a Call object with the type of the expected result. You can use replacement blocks and query parameters to adjust the URL. With the help of the Path annotation on the method parameter, the value of that parameter is bound to the specific replacement block. Query parameters are added with the Query annotation on a method parameter.

Additionally, it provides functionality for multipart request body and file uploads. Now we can build the interface for the API that will actually fetch the data from the server. Now we will make a little wrapper class for our API to keep the Retrofit initialization code wrapped up nicely. Calling enqueue tells Retrofit to make that call on a background thread and return the result to the callback that we're creating here. However, you don't need your own model class.

YAML, txt, custom format or you wish to use a different library to implement an existing format, you can easily create your own converter.
