我正在尝试使用 JWT 令牌实现基于令牌的身份验证。我为此使用 JJWT 库。

这是我的安全配置

@Override
protected void configure(HttpSecurity http) throws Exception {
    //http.csrf().disable();

    String[] patterns = new String[] {
        "/login",
        "/bower_components/**/*",
        "/app/**/*",
        "/index.html",
        "/home.html",
        "/signin.html"
    };
    http.authorizeRequests()
            .antMatchers(patterns)
            .permitAll()
            .antMatchers("/**/*").hasAuthority("ROLE_USER")
            .antMatchers("/*").hasAuthority("ROLE_USER")
            .and()
            .addFilterBefore(jwtAuthFilter, CsrfFilter.class)
            .exceptionHandling()
            .authenticationEntryPoint(jwtAuthEndPoint)
            ;
}

我正在使用弹簧靴。我通过以下方式调用此 api 来生成令牌。

   curl -v -X POST "http://localhost:8080/login" -d '{"username":"greenrabbit948", "password":"celeste"}' --header "Content-Type: application/json"   | jq .

使用令牌我调用我的其余 API，像这样

curl -i -X POST "http://localhost:8080/login" -d '{"username":"greenrabbit948", "password":"celeste"}' --header "Content-Type: application/json"
HTTP/1.1 200 OK

$ curl -s "http://localhost:8080/profile/details/yellowfrog347" --header "Authorization: Bearer eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJncmVlbnJhYmJpdDk0OCIsImV4cCI6MTQ2ODE0MDg1MiwiaXNzIjoiaW4uc2RxYWxpLmp3dCJ9.t9pqrOmYfaVkzuAQgo4D4VbN2PibQuHPuPA6RKYU-keTzbFAX58l77hQTc4Cq28HpjFOeiDvNpNEgilNHFOfVA" | jq .

    "first": "sofia",
    "last": "hansen"
  },
  "email": "sofia.hansen@example.com",
  "username": "yellowfrog347"
}

现在，每当我在没有令牌的情况下再次调用我之前调用的相同 API 时，都会显示数据。我怎样才能阻止这种情况发生？如何使令牌成为强制性的，以便仅在令牌存在时才显示数据？ 这发生在我使用 POSTMAN 调用 API 时。

您可以编写函数 gettoken() 来获取令牌。如果令牌可用，则返回 true，否则返回 false。希望您能得到答案。

为了实现这一点，您需要实现像 OAuth2 这样的授权框架并添加以下注释

  @PreAuthorize("#oauth2.hasScope('read') and #oauth2.hasScope('read')")

这将确保只有通过有效令牌，客户端才能访问服务。
