我用angular客户端编写了一个简单的spring security项目。 当我以角度的形式从登录表单向Java应用程序发送数据时,Java会向我返回消息,我发送的是null,但是以角度的形式,在发送之前我会检查它,但它不是null。
请帮助,我不知道出了什么问题=(

Java代码:
Model:
public class LoginForm {
@NotBlank
@Size(min=3, max = 60)
private String username;
@NotBlank
@Size(min = 6, max = 40)
private String password; ...
Controller:
@PostMapping("/signin")
public ResponseEntity<?> authenticateUser(@Valid @RequestBody LoginForm loginRequest) {
Authentication authentication = authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(loginRequest.getUsername(), loginRequest.getPassword()));
SecurityContextHolder.getContext().setAuthentication(authentication);
String jwt = jwtProvider.generateJwtToken(authentication);
UserDetails userDetails = (UserDetails) authentication.getPrincipal();
return ResponseEntity.ok(new JwtResponse(jwt, userDetails.getUsername(), userDetails.getAuthorities()));

答案 0 :(得分:0)
似乎LoginForm模型使用小写的“用户名”,并且您正在发送 console.log(data.userName,data.password);
userName-区分大小写的问题。 将角度登录模型转换为小写(用户名)
