nginx无法从头里获取Range字段

Range:

bytes=0-65535

直接访问服务能获取头里的信息,通过nginx就获取不到头,求助,nginx配置如下

underscores_in_headers on;
location ~ .*\.(js|css)$ {
    root /front_static/;
}

location /  {

    proxy_pass http://127.0.0.1:8686/;
    index index.html index.htm;
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header REMOTE-HOST $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_pass_request_headers on;
}

nginx会重命名自定义header,所以要加下面的配置,重新赋值请求头

proxy_set_header Range $http_range;
