废话不多说,就俩字:
快速开始
),尽量让您用起来没有障碍感!JustAuth(gitee | github)今日升级到1.8.1
版本,新增了AuthState
工具类,支持根据source
自动生成state
。

String state = AuthState.create(source);
System.out.println(state);
System.out.println("\nstep2 重复生成state: 预期从bucket中返回一个可用的state...");
String recreateState = AuthState.create(source);
System.out.println(recreateState);
Assert.assertEquals(state, recreateState);
System.out.println("\nstep3 获取state: 预期获取上面生成的state...");
String stateByBucket = AuthState.get(source);
System.out.println(stateByBucket);
Assert.assertEquals(state, stateByBucket);
System.out.println("\nstep4 删除state: 预期删除掉上面创建的state...");
AuthState.delete(source);
System.out.println("\nstep5 重新获取state: 预期返回null...");
String deletedState = AuthState.get(source);
System.out.println(deletedState);
Assert.assertNull(deletedState);
}
输出结果:

基础版的创建state
的方法,适用于对state
无复杂要求,只做简单验证时使用,内部通过source_ip_randomstr
的方式生成state
。
到这一步,可能有朋友会觉得,这功能太鸡肋了,限制太大了,只能生成固定格式的随机字符串,没法利用state做一些复杂的业务操作。我只想说,“莫慌~~”,这才哪到哪。
如果需要对state做特殊处理,比如要在state中保存当前用户信息(id)、当前页面的标识(bind-oauth)等更多的特殊参数时,可以使用以下方法:
create(String source, String body)
public static String create(String source, String body) {
return xx;
}
这个方法接收一个string类型的变量, 可以传入复杂的字符串类型, 也可以自己封装数据后转成字符串,然后调用这个接口。当然,针对非字符串的特殊结构参数,可以使用下面的方法。
create(String source, Object body)
public static String create(String source, Object body) {
return create(source, JSON.toJSONString(body));
}
这个方法接收一个Object类型的变量,支持任意一种数据类型,可以传入map、list、实体类等复杂结构的参数。
接下来演示一下通过AuthState
生成随机的、指定字符串的或者指定任意内容的state
字符串。用法如下:
@Test
public void create() {
String source = "github";
System.out.println("\n通过随机字符串生成state...");
String state = AuthState.create(source);
System.out.println(state);
AuthState.delete(source);
System.out.println("\n通过传入自定义的字符串生成state...");
String stringBody = "这是一个字符串";
String stringState = AuthState.create(source, stringBody);
System.out.println(stringState);
AuthState.delete(source);
System.out.println("\n通过传入数字生成state...");
Integer numberBody = 111;
String numberState = AuthState.create(source, numberBody);
System.out.println(numberState);
AuthState.delete(source);
System.out.println("\n通过传入日期生成state...");
Date dateBody = DateUtil.parse("2019-01-01 12:12:12", DatePattern.NORM_DATETIME_PATTERN);
String dateState = AuthState.create(source, dateBody);
System.out.println(dateState);
AuthState.delete(source);
System.out.println("\n通过传入map生成state...");
Map mapBody = new HashMap<>();
mapBody.put("userId", 1);
mapBody.put("userToken", "xxxxx");
String mapState = AuthState.create(source, mapBody);
System.out.println(mapState);
AuthState.delete(source);
System.out.println("\n通过传入List生成state...");
List listBody = new ArrayList<>();
listBody.add("xxxx");
listBody.add("xxxxxxxx");
String listState = AuthState.create(source, listBody);
System.out.println(listState);
AuthState.delete(source);
System.out.println("\n通过传入实体类生成state...");
AuthConfig entityBody = AuthConfig.builder()
.clientId("xxxxx")
.clientSecret("xxxxx")
.build();
String entityState = AuthState.create(source, entityBody);
System.out.println(entityState);
AuthState.delete(source);
}
输出结果:

怎么样? 是不是很爽?想往state中插入任何数据都可以。但是有些朋友可能又会说了:你这只生成了state,但是我怎么获取到我传入的具体的body内容?我就算生成的,但是我用不到这个数据,一样是“脱了裤子放屁 ——多此一举”。
咳~~ 还是那俩字:“莫慌~~”
前面介绍到了, 可以通过create(String source, String body)
或者create(String source, Object body)
生成复杂类型的state
,那么如何从encode之后的state
中获取到定制的body内容呢?
AuthState
提供了获取body内容的方法:
/**
* 获取state中保存的body内容
*
* @param source oauth平台
* @param state 加密后的state
* @param clazz body的实际类型
* @param 需要转换的具体的class类型
* @return state
*/
public static T getBody(String source, String state, Class clazz) {
...
}
方法接收三个参数,参数的作用如上注释,只要是按照规定规则({source}_{ip}_{body}
)生成的state,都可以通过getBody
方法解析出body内容。
示例代码:
@Test
public void getBody() {
String source = "github";
System.out.println("\n通过随机字符串生成state...");
String state = AuthState.create(source);
System.out.println(state);
String body = AuthState.getBody(source, state, String.class);
System.out.println(body);
AuthState.delete(source);
System.out.println("\n通过传入自定义的字符串生成state...");
String stringBody = "这是一个字符串";
String stringState = AuthState.create(source, stringBody);
System.out.println(stringState);
stringBody = AuthState.getBody(source, stringState, String.class);
System.out.println(stringBody);
AuthState.delete(source);
System.out.println("\n通过传入数字生成state...");
Integer numberBody = 111;
String numberState = AuthState.create(source, numberBody);
System.out.println(numberState);
numberBody = AuthState.getBody(source, numberState, Integer.class);
System.out.println(numberBody);
AuthState.delete(source);
System.out.println("\n通过传入日期生成state...");
Date dateBody = DateUtil.parse("2019-01-01 12:12:12", DatePattern.NORM_DATETIME_PATTERN);
String dateState = AuthState.create(source, dateBody);
System.out.println(dateState);
dateBody = AuthState.getBody(source, dateState, Date.class);
System.out.println(dateBody);
AuthState.delete(source);
System.out.println("\n通过传入map生成state...");
Map mapBody = new HashMap<>();
mapBody.put("userId", 1);
mapBody.put("userToken", "xxxxx");
String mapState = AuthState.create(source, mapBody);
System.out.println(mapState);
mapBody = AuthState.getBody(source, mapState, Map.class);
System.out.println(mapBody);
AuthState.delete(source);
System.out.println("\n通过传入List生成state...");
List listBody = new ArrayList<>();
listBody.add("xxxx");
listBody.add("xxxxxxxx");
String listState = AuthState.create(source, listBody);
System.out.println(listState);
listBody = AuthState.getBody(source, listState, List.class);
System.out.println(listBody);
AuthState.delete(source);
System.out.println("\n通过传入实体类生成state...");
AuthConfig entityBody = AuthConfig.builder()
.clientId("xxxxx")
.clientSecret("xxxxx")
.build();
String entityState = AuthState.create(source, entityBody);
System.out.println(entityState);
entityBody = AuthState.getBody(source, entityState, AuthConfig.class);
System.out.println(entityBody);
AuthState.delete(source);
}
运行结果:

me.zhyd.oauth.config.AuthConfig@725bef66
如上,通过getBody
获取到具体的body数据后,调用方可以根据自己的规则去校验state或者做其他逻辑操作。
作者:咋样? 这回没有问题了吧?
刺头:切,你有能耐让代码按照我的意念生成任意格式的state?
作者:噗~~(一口老痰喷他一脸)
前面主要通过源码+示例解释了AuthState
的用法,那么我们在实际使用JustAuth
时,只需要将state参数改为以下方式即可:
new AuthGithubRequest(AuthConfig.builder()
.clientId("xx")
.clientSecret("xx")
.redirectUri("https://www.zhyd.me/oauth/callback/github")
.state(AuthState.create(source)) // 1.8.1版本提供的生成state的方法
.build());
注意:授权登录后,需要手动清除本次请求流程中生成的state
AuthState.delete(source);
通过JustAuth-demo运行测试后的输出内容:
