How to define content type

(Rohit Kshirsagar) #1

Hello !
Greetings !

We are newbies in the Elasticsearch and we are currently fumbling over the following issue.

Objective : We are trying to fetch the json formatted files from a particular website and then use Elasticsearch to store and later search these files. These files will be dynamically generated with a fixed frequency. We have a Python script to call the files from the desired web site.

Issue: as we need the called files in the json files , we are trying to define the content Type in the python script but we are unable to do so.
Following is the code in Pythn , could you please give us some feedback on how to define the content type here ?

import elasticsearch
import simplejson as json
import requests
from elasticsearch import helpers
from bs4 import BeautifulSoup
import pandas as pd
from stringify import stringify_py

es = elasticsearch.Elasticsearch([{'host':'', 'port':9200}])
res = requests.get('')

r = requests.get("")

soup = BeautifulSoup(r.content, "lxml")
table = soup.find_all('table')[0]
df = pd.read_html(str(table))
data = df[0].to_json(orient = 'records')

es.index(index='test', doc_type='people', id=1, body=data)

Thanks ,

Do you mean when you call the remote website for the JSON files or when you index said JSON into ES? For the former, you will have to look up the docs for requests module I assume.

For the latter, what does the ES python SDK doc tell you?

Thank you for the response.

I would like to elaborate the exact error we are getting , this is occurring while indexing the JSON file.
Please refer the following which has a error message.

It would be a great help to us , if you can provide input here.
