#修改Swagger的配置

通过修改配置实现调用接口自带Authorization头，这样就可以访问需要登录的接口了。

#给PmsBrandController接口中的方法添加访问权限

  • 给查询接口添加pms:brand:read权限
  • 给修改接口添加pms:brand:update权限
  • 给删除接口添加pms:brand:delete权限
  • 给添加接口添加pms:brand:create权限

例子：

@PreAuthorize("hasAuthority('pms:brand:read')")
public CommonResult<List<PmsBrand>> getBrandList() {
    return CommonResult.success(brandService.listAllBrand());
}

#认证与授权流程演示

#运行项目，访问API

Swagger api地址：http://localhost:8080/swagger-ui.html

#未登录前访问接口

#登录后访问接口

  • 进行登录操作：登录帐号test 123456

  • 点击Authorize按钮，在弹框中输入登录接口中获取到的token信息

  • 登录后访问获取权限列表接口，发现已经可以正常访问

#访问需要权限的接口

由于test帐号并没有设置任何权限，所以他无法访问具有pms:brand:read权限的获取品牌列表接口。

#改用其他有权限的帐号登录

改用admin 123456登录后访问，点击Authorize按钮打开弹框,点击logout登出后再重新输入新token。
