我已经使用Spring Security使用登录名和密码实现了注册和身份验证。我用this tutorial做到了这一点。但现在我想使用Facebook Id提供注册和身份验证。我将在移动应用程序上获得Facebook用户的访问令牌，然后我将此访问令牌发送到我的Spring服务器（因此OAuth不适合），使用Facebook API验证它，并获得Facebook用户ID。请注意，我已经在我的数据库中使用Users，user_id，login，password列的表fb_id，因此注册有两种变体：用户将拥有登录名和密码，或者用户将只拥有Facebook帐户，我将使用他Facebook ID。
最后，我只需要验证此用户并返回JWT令牌。
已有代码。

AuthController：
//...
@PostMapping("/authorization")
public AuthorizationResponse AuthauthenticateUser(@Valid @RequestBody LoginRequest loginRequest) {
Authentication authentication = authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(
loginRequest.getPhone(),
loginRequest.getPassword()
)
);
SecurityContextHolder.getContext().setAuthentication(authentication);
String jwt = tokenProvider.generateToken(authentication);
User user = (User)authentication.getPrincipal();
AuthorizationResponse authorizationResponse = new AuthorizationResponse(user.getId(), jwt);
return authorizationResponse;
}
//...
那么，我如何使用Spring Security实现这一目标？
您可以创建一个API
id_token。id_token并获取用户的详细信息。这是一个示例代码 -
@PostMapping("/signin/facebook")
public ResponseEntity<?> signInWithFacebook(@Valid @RequestBody FBLoginRequest loginRequest) {
// Call facebook's API to validate id_token and get user's details
// Register new user (Note: Also add code to check if a user already exists with the given facebookId )
User user = new User(fbName, fbID,
emailId, null);
Role userRole = roleRepository.findByName(RoleName.ROLE_USER)
.orElseThrow(() -> new AppException("User Role not set."));
user.setRoles(Collections.singleton(userRole));
User result = userRepository.save(user);
// Authenticate User
UserPrincipal userPrincipal = UserPrincipal.create(result);
PreAuthenticatedAuthenticationToken authentication = new PreAuthenticatedAuthenticationToken(userPrincipal, null, userPrincipal.getAuthorities());
SecurityContextHolder.getContext().setAuthentication(authentication);
// Generate and return token
String jwt = tokenProvider.generateToken(authentication);
return ResponseEntity.ok(new JwtAuthenticationResponse(jwt));
}
我没有添加用于调用facebook的API的代码。但这应该是无足轻重的。
