springboot后端如何實現攜帶token登陸

目錄

實現思路

最終實現的效果為

項目結構

項目的結構為

對于接口的傳參數

獲取token
刷新token
攜帶token訪問資源

實現思路

使用oauth2+redis+mysql來完成登陸校驗，本案例使用oauth2簡單的密碼模式來實現。

最終實現的效果為

登陸頁面不設置權限審核，用戶通過登陸界面登陸，輸入賬戶密碼，后端接收到賬戶密碼之后會去數據庫驗證，如果驗證通過，則返回token給前端。
除了登陸頁面之外，其余的頁面訪問的時候會進行權限的鑒定，如果攜帶的token對應用戶的權限不足或沒有攜帶token、攜帶了錯誤的token，不允許訪問。
token具有時限，超時token會失效，可以通過refresh_token來刷新token的持續時間。

項目結構

項目的結構為

├─.idea
│  └─dictionaries
├─log
├─src
│  ├─main
│  │  ├─java
│  │  │  └─Rush
│  │  │      ├─config
│  │  │      ├─controller
│  │  │      ├─mapper
│  │  │      ├─pojo
│  │  │      ├─service
│  │  │      └─util
│  │  └─resource
│  └─test
│
└─target

項目的重點其實也就在于config包內

config包內定義了4個類：

AuthorizationServerConfig
ResourceServerConfig
WebSecurityConfig
CORSFilter「額外針對OAuth跨域問題」

除此之外，繼承了UserDetails接口的User類，繼承UserDetailsService類的UserService類也很關鍵。

除了這6個類之外，別的類和普通mybatis項目無異

對于接口的傳參數

獲取token

使用POST方法

http://localhost:8080/oauth/token?username=sang&password=123&grant_type=password&client_id=password&scope=all&client_secret=123

刷新token

使用POST方法

http://localhost:8080/oauth/token?grant_type=refresh_token&refresh_token=1a1c67a0-5f9b-49b1-9f95-dc7889c85cf5&client_id=password&client_secret=123

攜帶token訪問資源

在url內直接攜帶token

GET方法

http://localhost:8080/user/hello?access_token=9bdde947-19b7-46fe-8fe0-0f2804150768

在header內攜帶token

GET方法

http://localhost:8080/admin/hello
------------Header----------------
Authorization ： bearer 3929d92d-f5be-4b2d-9223-8b13e2412f14
Accept ： application/json
