tokens library

A Java library that keeps OAuth 2.0 service access tokens in memory for your usage.

Maven dependency

<dependency>
    <groupId>org.zalando.stups</groupId>
    <artifactId>tokens</artifactId>
    <version>see above</version>
</dependency>

Apache-Httpclient is also needed because we depend on it currently

So, you also have to add it with:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>your version</version>
</dependency>

Usage

AccessTokens tokens = Tokens.createAccessTokensWithUri(new URI("https://example.com/access_tokens"))
                            .manageToken("exampleRW")
                                .addScope("read")
                                .addScope("write")
                                .done()
                            .manageToken("exampleRO")
                                .addScope("read")
                                .done()
                            .start();

while (true) {
    final String token = tokens.get("exampleRO");

    Request.Get("https://api.example.com")
           .addHeader("Authorization", "Bearer " + token)
           .execute():

    Thread.sleep(1000);
}

Local testing

The "tokens" library allows injecting fixed OAuth2 access tokens via the OAUTH2_ACCESS_TOKENS environment variable. This allows testing applications using the library locally with personal OAuth2 tokens (e.g. generated by "zign"):

$ MY_TOKEN=$(zign token -n mytok)
$ export OAUTH2_ACCESS_TOKENS=mytok=$MY_TOKEN
$ lein repl # start my local Clojure app using the tokens library
