Access to XMLHttpRequest at 'http://localhost:8089/api/v1/auth/manage_login' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
新建一个java文件即可
package com.example.demo.config;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@SpringBootConfiguration
public class MyWebConfigurer implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry corsRegistry){
corsRegistry.addMapping("/**")
.allowCredentials(true)
.allowedOrigins("http://localhost:3000")
.allowedMethods("POST", "GET", "PUT", "OPTIONS", "DELETE")
.allowedHeaders("*")
.maxAge(3600);
}
}
里面的localhost:3000是前端的域名
