In this article, we have seen how we can set up a simple OAuth2 Client, and how we can integrate it in your REST calls to retrieve a secured resource from an external service. Finally we just print the response out. By default the client will send requests using HTTP/2. The builder can be used to configure per-client state, like: the preferred protocol version ( HTTP/1.1 or HTTP/2 ), whether to follow redirects, a proxy, an authenticator, etc. . This is done by means of a long-lived refresh token, which * This class is used for GET and POST communication wit an Apache HTTP, * Apache HttpComponents "HttpClient" - http://hc.apache.org/downloads.cgi. GoogleCredential The RetryHandler interface provides two methods, one for status exceptions (e.g. OAuthClient can use different java http clients with customized configurations like timeouts, connection pools, etc. Once we receive the response, we need to handle it, extracting the information we need for the access token. Simple OAuth library for Java. Commonly the In this article. To better understand the role of the OAuth2 Client, we can also use our own servers, with an implementation available here. In line with the OAuth2 specification, apart from our Client, which is the focus subject of this tutorial, we naturally need an Authorization Server and Resource Server.. We can use well-known authorization providers, like Google or Github. P.S Tested with HttpClient 4.5.10 pom.xml <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.10</version> </dependency> 1. Now let's start with the concept "Basic Authentication". It is really useful to parse and manipulate JSON in Java. Once we have the configuration values initialized, we can use them to build the HTTP request for the authorization server. subclasses of being accessed. you select among different credentials, depending on the flow you are using. API Client Library for Java is @Beta. Running some "rough/approx performance comparison tests" using Loom GET - requests a representation of the specified resource Summary: To access protected data stored on Google services, use 1. httpcomponents-client/lib/ commons-logging-1.1.3.jar; httpclient-4.3.2.jar; httpcore-4.3.1.jar; Compile all Java classes.
