How to make api call in python?

Question

I have ran tika server in my machine and call api using terminal which is working fine. I am able to extract text from image and pdf. But, I want to implement the api call in my python application.

curl -T price.xls http://localhost:9998/tika --header "Accept: text/plain"

Above is api call that i have to make. I can run this in my terminal and works fine but how to implement in python application. I have installed and tried requests.

API_URL = 'http://localhost:9998/tika'
APP_ROOT = os.path.dirname(os.path.abspath(__file__))
tika_client = TikaApp(file_jar=join(APP_ROOT,'../tika-app-1.19.jar'))
data = {
    "url": join(APP_ROOT,'../static/image/a.pdf')
}
response = requests.put(API_URL, data)
print(response.content)

Any help will be appreciate. Thank you :)

error output

Don't you need to pass in the payload data as a keyword argument? (`data=data`) — Sidharth Samant, Oct 10 '18 at 10:25

You need to define the data(payload), header.

url = 'http://localhost:9998/tika/......'
headers = {"Accept: text/plain"}
response = requests.put(url,data = data, headers=headers)

Have glance at this Making a request to a RESTful API using python

Can u attach both the outputs/screenshots? so that I can understand it. – Sheikh Arbaz Oct 10 '18 at 11:24
i have edit my question with error output, please have a look – Lama Madan Oct 10 '18 at 12:17
It seems you are not passing headers param. – Sheikh Arbaz Oct 10 '18 at 12:40
i did that, but forget to update that one, headers = {"Accept": "text/plain"} data = { "url": join(APP_ROOT,'../static/image/a.pdf') } response = requests.put(API_URL, data=data, headers=headers) still the same error – Lama Madan Oct 10 '18 at 12:52
Your application is unable to read that pdf, it's unable to parse it. may be you need to change the way you read the pdf. – Sheikh Arbaz Oct 10 '18 at 12:54
