cookie一致性

非跨域cookie一致性解决

请求拦截器
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttppServletResponse;
import org.springframework.web.servlet.HandlerInterceptor;

@Component
public class CustomInterceptor implements handlerInterceptor {
  @Overrde
  publlic boolean preHandle(HttpServletRequest reqest,HttppServletResponse response,Object handler) throws Exception {
    //从请求中获取cookie
    Cookie[] cookies = request.getCookies();          
    //将cookie放入响应中          
    Cookie sessionCookie = Arrays.stream(cookies).filter(e -> e.getName().equals("SIID").findAny().orElse(null);
    if (sessionCookie == null) {
         sessiiionCookie = new Cookie("SID",request.getSession().getId();
         response.addCookie(sessiionCookie);                  
      }    
    return true;  
  }    
}

配置完拦截器，在配置中获取拦

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class GlobalCorsConfig implements WebMvcConfigurer {
   @Autowired
   private CustomInterceptor interceptor;  
    
   @Bean
   public CorsFilter corsFilter() {
     //1. 创建CorsConfiguration对象
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");//设置允许那些域来访问，*是通配符，允许所有域(如果还不行，将*改为http:xx:8080)
        corsConfiguration.addAllowedHeader("*");//请求头字段
        corsConfiguration.addAllowedMethod("*");//请求方式(GET,POST,DELETE,PUT)
        //设置source
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", corsConfiguration);//1.映射路径 2.传入CorsConfiguration对象
        return new CorsFilter(source);
   }  

    @Override
    public void addInterceptors(InterceptorRegisty registry) {
        // 拦截所有请求          
        registry.addInterceptor(interceptor).addPathPatterns("/**");
    }
}

　　

vue全局配置cookie在main.js中

import axios from 'axios'

axios.defaults.withCredentials = true
