Python 1 app is calling url to receive DataFrame.
ret = requests.post(url, json = myobj)
Another python 2 app flask view function is supposed to reurn Dataframe .
How to do because falsk function is not able to return Dataframe.
You can choose JSON as the format for the data.
With pandas.DataFrame.to_json
the data frame is converted to JSON and can then be sent.
See also pandas.read_json
to convert the JSON data back into a data frame.
from flask import Flask
import io
import pandas as pd
import requests
app = Flask(__name__)
@app.route('/')
def index():
data = {
'Name': ['Gerald','Ben','Charlotte'],
'Age': [12, 25, 31],
}
df = pd.DataFrame(data, columns= ['Name', 'Age'])
return app.response_class(
df.to_json(orient='records'),
mimetype='application/json'
)
@app.route('/retrieve')
def retrieve():
r = requests.get(
'http://127.0.0.1:5000/',
headers={'Accept': 'application/json'}
)
r.raise_for_status()
df = pd.read_json(io.StringIO(r.text), orient='records')
print(df)
return ''
