On Java platforms OkHttp also supportsĬonscrypt, which integrates BoringSSL with Java. OkHttp uses your platform’s built-in TLS implementation. Track the dynamic TLS ecosystem and adjust OkHttp to improve connectivity and With HTTPS clients is an important defense against potential security problems. As with auto-updating web browsers, staying current We highly recommend you keep OkHttp up-to-date. Both are small libraries with strong backward-compatibility. OkHttp depends on Okio for high-performance I/O and the Kotlin standard library.

OkHttp works on Android 5.0+ (API level 21+) and Java 8+. get ( "application/json charset=utf-8" ) OkHttpClient client = new OkHttpClient () String post ( String url, String json ) throws IOException įurther examples are on the OkHttp Recipes page. Public static final MediaType JSON = MediaType. This program downloads a URL and prints its contents as a string. In this tutorial, we will make an https client call from java and log the output on the console. Supports both synchronous blocking calls and async calls with callbacks. This first example shows a combination of these Apache HttpClient classes used to get information from the Yahoo Weather API. Its request/response API is designed with fluent builders and immutability. It can beĬonfigured to fall back for broad connectivity. OkHttp supports modern TLS features (TLS 1.3, ALPN, certificate pinning). This is necessary for IPv4+IPv6 and services hosted in redundant dataĬenters. If your service has multiple IP addresses, OkHttp will attempt alternate addresses if theįirst connect fails. OkHttp perseveres when the network is troublesome: it will silently recover from common connection Response caching avoids the network completely for repeat requests.

Once an HttpResponse is received, the headers, response code, and body (typically) are available.

The BodyHandler determines how to handle the response body, if any. A BodyHandler must be supplied for each HttpRequest sent. Doing HTTPĮfficiently makes your stuff load faster and saves bandwidth. An HttpClient provides configuration information, and resource sharing, for all requests sent through it. ("Body: " + response.HTTP is the way modern applications network.
("Headers: " + response.headers().allValues("content-type")) ("Status code: " + response.statusCode()) Note that starting with JDK 11, Java provides a new API for performing HTTP requests, which is meant as a replacement for the HttpUrlConnection, the HttpClient API. HttpRequest request = HttpRequest.newBuilder() In this quick tutorial, we present a way of performing HTTP requests in Java by using the built-in Java class HttpUrlConnection. HttpClient httpClient = HttpClient.newBuilder() Make a request using nd() and get a response object. Stepsįollowing are the steps to use an HttpClient.Ĭreate HttpClient instance using HttpClient.newBuilder() instanceĬreate HttpRequest instance using HttpRequest.newBuilder() instance It is quite feature rich and now Java based applications can make HTTP requests without using any external dependency. It is recommended to use instead of other HTTP Client APIs like Apache Http Client API. With Java 11, now HttpClient is a standard. An enhanced HttpClient API was introduced in Java 9 as an experimental feature. HTTP clients encapsulate a smorgasbord of objects required to execute HTTP requests while handling cookies, authentication.
