How to control interface access permissions in OAuth2.0?
In OAuth2.0 applications, it is an important security consideration to ensure that the Company B H5 page nested in Company A App can only access specific interfaces, not all of Company A's interfaces. Especially after Company A issues access_token to Company B’s H5 page through OAuth2.0, it is crucial to limit the access scope of that token.
Scenario: Company A App is embedded in Company B’s H5 page, which requires access to the user information of Company A App. To obtain user information, you need to obtain the access_token of Company A through OAuth2.0. If there is no restriction, this token theoretically gives Company B the permission to access all interfaces of Company A, which poses a security risk.
The core of the solution lies in the scope mechanism of OAuth2.0. scope defines the permission scope of access_token, that is, the interface that token can access. When requesting access_token on the Company B H5 page, you need to clearly state the required scope, such as only requesting specific permissions such as "get mobile phone number", "get user name", and "get user email".
After the user authorizes these scopes in the Company A App, the Company A backend issues access_tokens containing these specific scopes. When using this token on the Company B H5 page to access the Company A resource server, the resource server will determine whether to allow access to the requested interface based on the scope in the token.
Therefore, the Company A resource server needs to implement logic to check the scope contained in the access_token of each request, and decide whether to allow access based on the scope. This ensures that Company B H5 pages can only access the interfaces preset by Company A and authorized by user.
It should be noted that scope and user authorization are two concepts. scope defines the maximum permissions allowed by Company A, and user authorization determines the permissions that are actually accessible. By reasonably setting scope and user authorization mechanisms, Company A can effectively control the access of Company B's H5 page to the App interface to ensure security and privacy.
