To integrate with other parts of your application, you’ll often need to use an alternate backend (but what’s important is that the API remains the same!). See the section on backends for a short guide on which backend to choose, and a list of all implementations.
The basic dependency which provides the API and the default synchronous backend is:
"com.softwaremill.sttp.client" %% "core" % "2.0.6"
sttp client is available for Scala 2.11, 2.12 and 2.13, and requires Java 8.
sttp client is also available for Scala.js 0.6. Note that not all modules are compatible and there are no backends that can be used on both.
If you are an Ammonite user, you can quickly start experimenting with sttp by copy-pasting the following:
import $ivy.`com.softwaremill.sttp.client::core:2.0.6` import sttp.client.quick._ quickRequest.get(uri"http://httpbin.org/ip").send()
quick object has the same effect as importing
sttp.client._, plus defining an implicit synchronous backend (
implict val backend = HttpURLConnectionBackend()), so that sttp can be used right away.
If the default
HttpURLConnectionBackend for some reason is insufficient, you can also use one based on OkHttp:
import $ivy.`com.softwaremill.sttp.client::okhttp-backend:2.0.6` import sttp.client.okhttp.quick._ quickRequest.get(uri"http://httpbin.org/ip").send()
Working with sttp is most convenient if you import the
sttp.client package entirely:
This brings into scope the starting point for defining requests and some helper methods. All examples in this guide assume that this import is in place.
And that’s all you need to start using sttp client! To create and send your first request, import the above, type
basicRequest. and see where your IDE’s auto-complete gets you! Here’s a simple request, using the synchronous backend:
import sttp.client._ implicit val backend = HttpURLConnectionBackend() val response = basicRequest .body("Hello, world!") .post(uri"https://httpbin.org/post?hello=world").send() println(response.body)
