tika-app-python

Overview

tika-app-python is a wrapper for Apache Tika App. With this library you can analyze:

• file on disk
• payload in base64
• file object (like standard input)

To use file object function you should use Apache Tika version >= 1.17.

Installation

Clone repository

git clone https://github.com/fedelemantuano/tika-app-python.git

and install tika-app-python with setup.py:

cd tika-app-python

python setup.py install

or use pip:

pip install tika-app

Usage in a project

Import TikaApp class:

from tikapp import TikaApp

tika_client = TikaApp(file_jar="/opt/tika/tika-app-1.18.jar")

For get content type:

tika_client.detect_content_type("your_file")

For detect language:

tika_client.detect_language("your_file")

For detect all metadata and content:

tika_client.extract_all_content("your_file")

For detect only content:

tika_client.extract_only_content("your_file")

For detect only metadata:

tika_client.extract_only_metadata("your_file")

You can analyze payload in base64 with the same methods, but passing payload argument:

tika_client.detect_content_type(payload="base64_payload")
tika_client.detect_language(payload="base64_payload")
tika_client.extract_all_content(payload="base64_payload")
tika_client.extract_only_content(payload="base64_payload")
tika_client.extract_only_metadata(payload="base64_payload")

or you can analyze file object (like standard input) with the same methods, but passing objectInput argument:

tika_client.detect_language(objectInput="objectInput")
tika_client.extract_all_content(objectInput="objectInput")
tika_client.extract_only_content(objectInput="objectInput")
tika_client.extract_only_metadata(objectInput="objectInput")

Usage from command-line

If you installed tika-app-python with pip or setup.py you can use it with command-line. To use tika-app-python you should submit the Apache Tika app JAR. You can:

• set the enviroment value TIKA_APP_JAR
• use --jar switch

The last one overwrite all the others.

These are all swithes:

usage: tikapp [-h] (-f FILE | -p PAYLOAD | -k) [-j JAR] [-d] [-t] [-l]
                   [-m] [-a] [-v]

Wrapper for Apache Tika App.

optional arguments:
  -h, --help            show this help message and exit
  -f FILE, --file FILE  File to submit (default: None)
  -p PAYLOAD, --payload PAYLOAD
                        Base64 payload to submit (default: None)
  -k, --stdin           Enable parsing from stdin (default: False)
  -j JAR, --jar JAR     Apache Tika app JAR (default: None)
  -d, --detect          Detect document type (default: False)
  -t, --text            Output plain text content (default: False)
  -l, --language        Output only language (default: False)
  -m, --metadata        Output only metadata (default: False)
  -a, --all             Output metadata and content from all embedded files
                        (default: False)
  -v, --version         show program's version number and exit

Example from file on disk:

$ tikapp -f example_file -a

Example from standard input

$ tikapp -a -k < example_file
