Question

我使用django + nginx + uwsgi

编写了文件下载代码

以下是我的代码

def download_latest_db(request):
    latest_db = DB.objects.all().first()
    chunk_size = 8192
    if latest_db is not None:
        response = FileResponse(FileWrapper(open(latest_db.locate, 'rb'), chunk_size))
        response['Content-Length'] = os.path.getsize(latest_db .locate)
        response['Content-Disposition'] = 'attachment; filename="%s.db"'% latest_db.version
        return response
    return Response(status=404)

但是当我尝试五次时，文件下载几乎失败了并且它不会在runserver模式下发生

我猜这是nginx设置的问题。请帮帮我

以下是我的nginx设置。我使用基本设置

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

        ##
        # Basic Settings
        ##

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        # server_tokens off;

        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        ##
        # SSL Settings
        ##

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
        ssl_prefer_server_ciphers on;
        ##
        # Logging Settings
        ##

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        ##
        # Gzip Settings
        ##

        gzip on;
        gzip_disable "msie6";

        # gzip_vary on;
        # gzip_proxied any;
        # gzip_comp_level 6;
        # gzip_buffers 16 8k;
        # gzip_http_version 1.1;
        # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

        ##
        # Virtual Host Configs
        ##

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
}


#mail {
#       # See sample authentication script at:
#       # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
#
#       # auth_http localhost/auth.php;
#       # pop3_capabilities "TOP" "USER";
#       # imap_capabilities "IMAP4rev1" "UIDPLUS";
#
#       server {
#               listen     localhost:110;
#               protocol   pop3;
#               proxy      on;
#       }
#
#       server {
#               listen     localhost:143;
#               protocol   imap;
#               proxy      on;
#       }
#}

我应该添加其他选项吗？

我认为你需要提高你的nginx client_max_body_size设置。默认值为1MB，对于名为“download_latest_db”= D

的视图来说可能太小
