Be sure to exclude Netty from all appropriate com.azure libraries, as shown here:
#Java http client example how to#
The following example shows you how to exclude the Netty dependency from a real dependency on the azure-security-keyvault-secrets library. In a Maven pom.xml file, you exclude the Netty dependency and include another dependency. If you prefer another implementation, you can remove the dependency on Netty by excluding it in the build configuration files. The new HttpClient introduced in JDK 11.As such, the Netty HTTP client is the default client used in all Azure SDK for Java libraries.Īlthough Netty is the default HTTP client, the SDK provides three client implementations, depending on which dependencies you already have in your project. However, to simplify dependency management for most users, all Azure client libraries depend on azure-core-http-netty. This abstraction enables a pluggable architecture that accepts multiple HTTP client libraries or custom implementations. The Azure SDK for Java is implemented using an HttpClient abstraction. This functionality provides a consistent, powerful, and flexible experience for developers using all Azure SDK for Java libraries. You may use thisĭomain in examples without prior coordination or asking for permission.This article provides an overview of using the HTTP client and pipeline functionality within the Azure SDK for Java. This domain is established to be used for illustrative examples in documents.
HttpClient client = HttpClient.newHttpClient() ĬompletableFuture> future = ndAsync(request, bodyHandler) sending request and receiving response via HttpClient HttpResponse.BodyHandler bodyHandler = () GET()//used by default if we don't specify HttpRequest request = HttpRequest.newBuilder() It implements various useful handlers, such as handling the response body as a String, or streaming the response body to a file. For example HttpResponse.BodyHandler is used to read the response body. We typically use one of its static nested interfaces to specify how we want to receive the response. HttpResponse The instance of this class is returned as a result of sending an HttpRequest.The method ndAsync() is used to send the given request asynchronously, it returns CompletableFuture>. The instance of this class is obtained by invoking HttpClient.newHttpClient(). HttpClient This class is used to send HTTP requests and to receive their responses.The HttpRequest.build() method returns a new HttpRequest instance. All setter methods returns the same instance allowing the calls to be chained together. The instance of this builder is create by invoking HttpRequest.newBuilder(). HttpRequest.Builder This builder helps us to prepare HttpRequest object.HttpRequest This class encapsulates HTTP request's URI, headers and body.In this getting started tutorial we will get familiar with the following classes provided in package: This API is the recommended alternative to URLConnection API. The API supports both HTTP 1.1 and HTTP 2. This API provides non-blocking request and response semantics through CompletableFuture. Java 11 standardizes this API (package ). Java 9 introduced HTTP Client as an incubating API (package ).
