问题描述

我的 Spring Boot (2.4.4) 应用程序中有下一个 CORS 配置:

@Configuration
public class CORSConfiguration {
    @Bean
    public WebMvcConfigurer cors() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedOrigins("*");
            }
        };
    }
}

在某个时间点,我开始遇到下一个异常:

java.lang.IllegalArgumentException: When allowCredentials is true, allowedOrigins cannot contain the special value "*" since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.

之后,我根据答案修复了我的配置:

registry.addMapping("/**").allowedOriginPatterns("*");

之后,CORS 的问题就消失了。据我了解,我不能使用allowedOrigins("*")with allowCredentials(true)。好的,很清楚。但是我根本没有添加allowCredentials(true)我的代码。也许这是默认值(?)。

然后我决定用下一种方式编写我的配置:

registry.addMapping("/**").allowCredentials(false).allowedOrigins("*");

CORS 和异常的问题又回来了。尽管allowCredentials(true)我将以下值指定为allowCredentials(false). 我错了什么?allowCredentials或者为什么 Spring在某些情况下会覆盖 的值?


我失败的 CORS 请求

解决方案


试试这个,并确保添加客户端的正确来源,并将所需的允许方法放在那里。我只是随意放在那里

public void addCorsMappings(CorsRegistry registry) {
         registry.addMapping("/**")
                .allowedOrigins("http://localhost:13000")              
     .allowedMethods("HEAD","GET","POST","PUT","DELETE","PATCH").allowedHeaders("*");       
}
