Viewer problem running behind Apache

Dibarcus · 07-13-2020, 02:45 PM

I've been running calibre-server 4.20 behind Apache using digest authentication with no problems. But I wanted the sync feature to work so I got rid of digest authentication and setup the calibre user database. Now I'm having trouble with the Viewer webapp. I've cleared the browser cache, credentials, etc but the problem persists.

All catalog browsing functions appear to work and downloading always works, but when a book is selected and "Read" is pressed, I see this error error in the browser: (firefox)

Code:

Could not download book
Could not open MyBook. Failed to download some book data, click "Show details" for more information

Details:

Code:

OEBPS/Text/vde31.05.xhtml
Failed to communicate with "/book-file/827/EPUB/789472/15944457100/OEBPS/Text%2Fvde31.05.xhtml? library_id=Calibre_Library&1594651600287", with status: [400 (error)] Bad Request

The uri in the Request Line and the Authorization header do not match

From the system log

Code:

server calibre-server[1636444]: Authorization URI mismatch: 

(u'book-file', u'827', u'EPUB', u'789472', u'15944457100', u'OEBPS', u'Text', u'vde31.05.xhtml') 
!= 
(u'book-file', u'827', u'EPUB', u'789472', u'15944457100', u'OEBPS', u'Text/vde31.05.xhtml') 

from client: 127.0.0.1

Calibre server is started from a systemd script:

Code:

[Unit]
Description=calibre content server
After=network.target

[Service]
Type=simple
User=calibre
Group=calibre
ExecStart=/opt/calibre/calibre-server \
	--port 8082 \
	--listen-on 127.0.0.1 \
	--userdb /etc/httpd/calibre.sqlite \
	--enable-auth \
	"/share/Calibre Library" 

[Install]
WantedBy=multi-user.target

Apache configuration:

Code:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

<VirtualHost *:80>
	ServerName calibre.myserver.com
	AllowEncodedSlashes On
	ProxyPreserveHost On
	ProxyPass "/" http://localhost:8082/
</VirtualHost>

To make the problem more mysterious, some titles in my collection work ok with the Viewer. But all of them worked before I switched to using the built-in calibre user database instead of apache authentication.

Thanks for any insights.

The problem has to do with the slashes in the file names. Its over a decade since I used apache so cant help you with that. You will need to get apache to handle the slashes correctly.

It does appear to be a slash problem. I decided that I prefer to run calibre-server directly because of the user database feature.

Thanks
