Docker LibreOffice Online Integration(WOPI) Error

Hi! I encountered a problem with the personal application I tried to integrate with LOOL. I have implemented the WOPI Host service and it runs normally in MS Office Online.

I also tried to use NextCloud to integrate the same LOOL, everything is normal, but my WOPI Host is not working.

I think there may be a problem with the downloaded file when calling WOPI’s download file interface.
link text

So I tried to capture this request and compare the response returned by NextCloud. And i captured this request and compared the response returned by NextCloud. The HTTP response codes returned are all 200, and the file content is complete.

This is my environment info:

Kernel Version: 3.10.0-1127.13.1.el7.x86_64
Operating System: CentOS Linux 7 (Core)
OSType: linux
Architecture: x86_64
CPUs: 16
Total Memory: 7.62GiB

The docker image info:

libreoffice/online master 1ae6e6097e49 3 months ago 3.06GB

If you need a complete error log and HTTP data, please leave your email. thanks for your help!

I fixed this bug.
I replace

Now I use

+ '&lang=en'

and everything is normal
