篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了无法在Angular / SpringBoot应用程序中获取OAuth2令牌相关的知识，希望对你有一定的参考价值。

我已经创建了OAuth2 SpringBoot（v 2.2.6.RELEASE）项目。我想使用“密码”授予流从SPA（Angular 8应用程序）对用户进行身份验证。以下是AuthorizationServer的代码：

@Configuration
@EnableWebSecurity
public class AuthorizationServerConfig extends WebSecurityConfigurerAdapter implements AuthorizationServerConfigurer {

    @Autowired
    private DataSource dataSource;

    @Autowired
    private AuthenticationManager authenticationManager;

    @Bean
    public TokenStore getJdbcTokenStore(){
        return new JdbcTokenStore(this.dataSource);
    }

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Bean
    public PasswordEncoder getPasswordEncoderBean(){
        return NoOpPasswordEncoder.getInstance();
    }

    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.checkTokenAccess("isAuthenticated()").tokenKeyAccess("permitAll()");
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer client) throws Exception {
        client.jdbc(dataSource).passwordEncoder(passwordEncoder);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoint) throws Exception {
        endpoint.tokenStore(this.getJdbcTokenStore());
        endpoint.authenticationManager(authenticationManager);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.antMatcher("/**")
            .authorizeRequests()
            .antMatchers("/oauth/token").permitAll()
            .anyRequest().authenticated()
            .and()
            .httpBasic();
    http.cors();
    }
}

[当我用Postman调用'http://localhost:8080/oauth/token'端点时，一切似乎都工作正常，并且我得到了以下响应：

{
    "access_token": "fa66b6af-90d1-490b-9ea3-ffcfbe8042c0",
    "token_type": "bearer",
    "refresh_token": "44303904-b21c-42fc-aa56-fa264563909b",
    "expires_in": 3276,
    "scope": "READ WRITE"
}

但是当我使用Angular Application调用同一终结点时，响应失败。在Spring Server日志中打印以下错误：

下面是从chrome发送到服务器的请求的屏幕截图：

这是调用后端服务的角度代码：

    let headers = new HttpHeaders({
      "Accept" : "application/x-www-form-urlencoded"
    });
    this.options = { headers: headers };

    let authData : FormData = new FormData();
    authData.set('grant_type', 'password');
    authData.set('username', auth.userId);
    authData.set('password', auth.password);

    return this.httpClient.post<UserModel>('http://localhost:8080/oauth/token', authData,this.options);

如果有人可以引导我朝正确的方向前进，那就太好了。

答案

[Authorization在标题部分中缺少，标题将如下所示：

      const headers = {
            'Authorization': 'Basic ' + btoa(`${appClainUserName}:${appClientPass}`),
            'Content-type': 'application/x-www-form-urlencoded; charset=utf-8'
        }
