春季安全证书:源已被CORS策略禁止

Question

在一个具有角的项目中，我第一次使用spring引导，在我添加spring安全依赖之前，一切都很好

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-test</artifactId>
    <scope>test</scope>
</dependency>

现在，我在客户端得到了这个错误：

Access to XMLHttpRequest at 'http://localhost:8080/api/v1/login' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

我试图按照文档的建议更改配置，所以我添加了类。

src/main/java/com/example/securingweb/WebSecurityConfig.java

@Configuration
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer{

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

我的控制器里也有这样的东西：

@CrossOrigin(origins = "http://localhost:4200")

Answer 1

由于您已经添加了Spring安全依赖项，所以spring将启用Basic Auth，这将验证您的每个请求。这也使得CORS(跨源请求共享)成为可能。尽管您已经为每个请求添加了CrossOrigin，但这还不足以禁用CORS。

关于CORS的更多详细信息

因此，要么您需要发送spring安全生成的令牌，它将打印在您的控制台上。

或

您需要配置Spring安全配置类，这将验证您的自定义或允许特定的url。
