ResponseHeaders重复问题

本地测试无问题，但是别人请求说是有跨域问题，翻译问题发现

研究headers发现有重复的地方

研究代码发现SpringBoot项目中配置了Headers，ng也配置了Headers，重复了也就报错了

public class XssFilter implements Filter {
	public void addHeader(HttpServletRequest req,HttpServletResponse response) {
		if (!req.getRequestURI().contains("app/customer")) {
			response.addHeader("Access-Control-Allow-Origin", "*");
			response.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
			response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Token, CustomerId");
			response.setHeader("Content-Type", "application/json;charset=utf-8");
			response.addHeader("Access-Control-Max-Age", "1800");//30 min
		};
	}
}

location /apis/ {
        add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE' always; add_header 'Access-Control-Allow-Credentials' 'true' always; add_header 'Access-Control-Allow-Origin' '*' always; add_header 'Access-Control-Allow-Headers' '*' always;
        if ($request_method = OPTIONS ) {return 200;}
        rewrite  ^.+apis/?(.*)$ /$1 break;
        include  uwsgi_params;
        proxy_pass   http://localhost:8091;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
