![]() Support for HTTP authentication protocols. Receives, stores, sends and allows manipulation of cookies. Support for sending multipart requests to the server.Īs with forms, we’re interested in whether the client provides an API specifically for this. Note: all clients can do this if you’re willing to build up the request from scratch yourself, so what we’re really talking about here is whether a specific API is provided. Support for posting of form data to the server. Support for version 2 of the HTTP protocol. ![]() Such as Square’s Retrofit or Spring’s WebClient that adapt these to other styles such as reactive streams. Style (futures or callbacks typically), there are a number of wrapper libraries It’s worth pointing out that although most clients with an asynchronous API only support one In practice, this is one or more of futures, callbacks or reactive streams. We also indicate what style (or styles) of async API is presented, if any. Whether the client supports a synchronous (blocking) call style, asynchronous (non-blocking) or both. documentation, the following features can easily be described in yes/no form and are summarised for each client in the table below. While some factors are somewhat qualitative e.g. The last three of these are deep topics in their own right, and we’ll write more about these in future articles. Operability, reliability and observability. ![]() Obviously, each project’s requirements are somewhat unique, but there are several common factors that most teams would wish to consider: So what should we consider when choosing an HTTP client? We’re only going to discuss clients that actually implement the HTTP protocol, so libraries such as Spring’s RestTemplate or Feign that act as higher-level wrappers will not be discussed (although we may look at these in a future article). ![]() This article aims to provide an overview of the major libraries, with a focus on the characteristics you’re likely to care about when making a selection for your project. This can make choosing the right HTTP client less than straightforward. This can be a specific generic type likeīodyHandler or more general type like BodyHandler.HTTP has become the dominant protocol for integration of networked programs, and consequently many (possibly most) Java projects need to be able to make HTTP calls to other systems.Īs with many things in the Java ecosystem, a broad array of alternatives exist for achieving this, both via core libraries and open source. The method can also declare one parameter of type .BodyHandlerĪnd this will be used to handle the response body. whenComplete (( hres, throwable ) -> Response typesīelow is a tabe of the API response types can be used and the resulting generated code. This client API generation targets avaje-http-client / JDK HttpClient onlyĪnd uses source code generation via annotation processing so there is no use of reflection and noĬlient.
