如何使用具有完整路径的JavaScript从服务器读取文本文件？

Question

I want load a remote file from a server.

This file is not in a web site. So when I open a file I use

window.open('http://5.135.140.184:8080/tpi/documents/D773.JPG', '_blank'); 

This opens my picture. But if I want to use a complete path, I use

window.open("http://5.135.140.184:8080/var/lib/tomcat/webapps/tpi/documents/D773.JPG", '_blank'); 

In this case I have a 404 error ... How do I do?

PSThe file D773.JPG is in the path var/lib/tomcat/webapps/tpi/documents

You can only access things via HTTP that are served by an HTTP (eg, "web") server which recognizes and handles the URL you give it. It would be possible to configure an HTTP server to allow you to access any file by full path, but it would almost certainly be an extraordinarily bad idea to make **all* files on a machine accessible via HTTP.

Your question contradicts itself by saying both that the file isn't in a web site and that you can access the file via http://5.135.140.184:8080/tpi/documents/D773.JPG . If you can access the file via that URL, then an HTTP server at 5.135.140.184:8080 is running and handles that URL by giving you the file. That's what you should stick with.

I want load an other file that is not in the web sites.

You can't, not via HTTP. HTTP requires a web server that understands the URL. If your web server at 5.135.140.184:8080 isn't configured to deliver the file you want, you cannot access it via HTTP (without changing the server configuration).
