SpringBoot后端配置允许自定义header

前言：前后端分离项目，前端传入自定义的header参数对服务器发起请求，但显示跨域错误解决：创建一个拦截器，在拦截器中编辑允许的自定义header，例子如下：public class AdminInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request

前言：前后端分离项目，前端传入自定义的header参数对服务器发起请求，但显示跨域错误

解决：创建一个拦截器，在拦截器中编辑允许的自定义header，例子如下：

public class AdminInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        String origin  = request.getHeader(HttpHeaders.ORIGIN);
        if (origin != null) {
            response.setHeader("Access-Control-Allow-Origin", "*");
            response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PUT, HEAD");
            //这里设置允许的自定义header参数
            response.setHeader("Access-Control-Allow-Headers", "Content-Type, Token, adminID");
            response.setHeader("Access-Control-Max-Age", "3600");
        }
	}
}
