    #跨域配置
    add_header Access-Control-Allow-Origin *;
    add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
    add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization,accesstoken';

    root   /www;

跨域注意事项

错误提示
Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header contains multiple values 'http://localhost:9080, *', but only one is allowed. Origin 'http://localhost:9080' is therefore not allowed access.

Access-Control-Allow-Origin只允许一个值
nginx或php配置其中一种就可以了

php配置跨域

//通用控制器添加：
public function init() {
    parent::init();
    //允许所有来源访问
    header('Access-Control-Allow-Origin:*');    
    //允许访问的方式
    header('Access-Control-Allow-Method:GET,POST,PUT,PATCH,DELETE,HEAD,OPTIONS,HEAD');
   //允许自定义的头部参数
    header("Access-Control-Allow-Headers:Origin,X-Requested-With,Content-Type,Accept,Authorization");   
}

//或者直接在入口文件头部添加：
//允许所有来源访问
header('Access-Control-Allow-Origin:*');    
//允许访问的方式
header('Access-Control-Allow-Method:GET,POST,PUT,PATCH,DELETE,HEAD,OPTIONS,HEAD');
//允许自定义的头部参数
header("Access-Control-Allow-Headers:Origin,X-Requested-With,Content-Type,Accept,Authorization");
