使用 OAuth 2.0 資源伺服器 JWT 時出現權限(授權)問題

在使用 OAuth 2.0 資源伺服器 JWT 時,有時會遇到權限(授權)問題。這是許多開發人員在開發過程中經常遇到的挑戰。 OAuth 2.0 是一種用於授權的開放標準,它允許使用者授權第三方應用程式存取其受保護的資源。 JWT(JSON Web Token)是一種用於在網路應用程式之間傳遞聲明的方式。然而,在實務中,可能會出現一些權限問題,例如授權失敗、無法取得存取權杖等。本文將針對這些問題進行解析,並提供一些解決方案,幫助開發人員更好地使用 OAuth 2.0 資源伺服器 JWT。

問題內容

我正在嘗試使用 oauth 2.0 資源伺服器 jwt 在一個簡單的應用程式中使用 jwt 設定存取授權。

整個身份驗證部分工作正常,但我在授權方面遇到問題。即使令牌中存在正確的權限,所有受保護的端點也會給予 403 forbidden 錯誤。

我嘗試使用預設範圍(scope_)屬性並將配置更改為角色(role_),但問題仍然存在。

有誰知道怎麼解決嗎?

私人控制器:#

@RestController
@RequestMapping("private")
public class PrivateController {

  @GetMapping
  //@PreAuthorize("hasAuthority('ROLE_ADMIN')")
  public String getMessage() {
    return "Hello from private API controller";
  }
  
}

解決方法

已產生提供的令牌,並將

roles 欄位設為 ROLE_ADMIN。在 jwtAuthenticationConverter() 中,您嘗試將 setAuthorityPrefixROLE 一起使用,導致 ROLE_ROLE_ADMIN

要修正此問題,請將該行修改為

grantedAuthoritiesConverter.setAuthorityPrefix("");

進行此調整後,問題應該得到解決。如果您遇到任何其他問題,請告訴我。

注意:

如果省略此步驟,預設前綴將為

SCOPE,導致您的角色變為 SCOPE_ROLE_ADMIN
