Wt

Hi,

I have a WFileResource which I want to redirect to, from within my app to trigger browser download. Unfortunately, I'll get 404 error as soon as the browser redirects to the resource.

Here is the example code:

    WFileResource *fileResource = new Wt::WFileResource(Mime::GetMime(Mime::FileType::Xlsx), filePath.string(), m_parent);
    fileResource->suggestFileName(filePath.filename().string());
    app->redirect(fileResource->url());

And my Nginx configuration looks like this:

    upstream example {
        server 127.0.0.1:8888;
    }

    server {
        server_tokens   off;

        listen          443 default_server ssl http2;
        listen          [::]:443 default_server ssl http2;
        server_name     www.example.com;

        include         /srv/confing/ssl-example-com;

        charset utf-8;
        merge_slashes on;

        root /srv/example.com/www;

        location / {
            gzip off;

            proxy_read_timeout 300;
            proxy_connect_timeout 300;
            proxy_redirect off;

            proxy_http_version 1.1;

            # WebSocket proxying
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;

            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-Ssl on;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header X-Frame-Options SAMEORIGIN;

            proxy_pass http://example;

            # Remove the http proxy header to address HTTPoxy vulnerability
            proxy_set_header Proxy "";
        }

        # Error Pages
        include /srv/confing/error;

        # Anti-DDoS
        include /srv/confing/anti-ddos;

        # Compression
        include /srv/confing/compression;

        # Static Resource Caching
        include /srv/confing/static-resource-caching;
    }

Here is the nginx log:

    2017/04/14 20:45:31 [error] 77046#100474: *1 open() "/srv/example.com/www/5_BD Info.xlsx_2017_04_07_17_59_21.xlsx"
    failed (2: No such file or directory), client: 37.32.114.209, server: www.example.com, request: "GET 
    /5_BD%20Info.xlsx_2017_04_07_17_59_21.xlsx?wtd=TvmEDnefTvoB5Uxm&request=resource&resource=oe2wx8v&rand=2
    HTTP/2.0", host: "www.example.com", referrer: "https://www.example.com/?lang=en"

In contrast to http://redmine.webtoolkit.eu/projects/wt/wiki/Fastcgi_on_nginx#nginx-configuration I don't use FastCGI since I need to proxy websockets through nginx.

I don't have any clue on how to achieve the same results (make internal paths work) as fastcgi_split_path_info with proxy_pass. Is there any easy way to fix this?

Thank you!
