反向代理OBS不能预览问题

vim /etc/nginx/conf.d/default.conf

nginx反代加上：

proxy_hide_header "Content-Disposition"; 
add_header "Content-Disposition" "inline";

Nginx加上上述可以让反代忽略自动添加的头域

server {
    listen       80;
    server_name  localhost;

    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        #root   /usr/share/nginx/html;
        proxy_pass  https://xxxxxxxxxx.obs.cn-north-4.myhuaweicloud.com;  #此处填写OBS桶访问域名，以http://或https://开头
        index  index.html index.htm;
        proxy_hide_header "Content-Disposition";
        add_header "Content-Disposition" "inline";

    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
