python how to use tika with existing jar file without downloading again

问题

I'm using Tika and I realized that each time the jar file is downloaded and placed in Temp folder

Retrieving http://search.maven.org/remotecontent?filepath=org/apache/tika/tika-server/1.19/tika-server-1.19.jar to C:\Users\asus\AppData\Local\Temp\tika-server.jar.
Retrieving http://search.maven.org/remotecontent?filepath=org/apache/tika/tika-server/1.19/tika-server-1.19.jar.md5 to C:\Users\asus\AppData\Local\Temp\tika-server.jar.md5.

The problem is that the jar file size is around 60MB, which takes some time to download.

This is the code I'm using :

from tika import parser

def get_pdf_text(path):
    parsed = parser.from_file(path):
    return parsed['content']

The only workaround I found is this :

1 - Manually running the jar using java -jar tika-server-x.x.jar --port xxxx

2 - Using tika.TikaClientOnly = True

3 - Replacing parser.from_file(path) with parser.from_file(path, '/path/to/server')

But I don't want to run the jar file manually. It would be better if I can use Python to automatically run the jar file and setup tika with it without redownloading.

回答1:

To resolve this problem you should add an environment variable to the tika server jar and specify the path folder which contains the tika jar file.

TIKA_SERVER_JAR = 'PATH_OF_FOLDER_CONTAINING_TIKA_SERVER_JAR'.
