Access to XMLHttpRequest at 'http://localhost:8090/user/list' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
这是今天做SpringBoot+Vue项目时候遇到的问题,查了一下这是SpringBoot的跨域问题,这边给大家推荐文章链接【精选】SpringBoot解决跨域的5种方式_springboot 跨域-CSDN博客
我这边采用的是重写WebMvcConfigurer(全局跨域)方法,代码如下
@Configuration public class CorsConfig implements WebMvcConfigurer { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**") //是否发送Cookie .allowCredentials(true) //放行哪些原始域 .allowedOrigins("*") .allowedMethods(new String[]{"GET", "POST", "PUT", "DELETE"}) .allowedHeaders("*") .exposedHeaders("*"); } }
但是采用这种方法以后后续还有一个问题就是会报一个错误
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.
这个时候遇到问题不要怕,我们直接百度,当allowCredentials为true时,allowedOrigins不能包含特殊值"*",因为它不能在"Access-Control-Allow-Origin"响应头中设置。 要允许凭证指向一组起源,可以显式地列出它们,或者考虑使用“allowedOriginPatterns”代替。原文链接:【解决】When allowCredentials is true, allowedOrigins cannot contain the special value “*“ since-CSDN博客
所以解决方式就是把allowedOrigins改成allowedOriginPatterns,最后不再报错问题解决
