Example 1: simple flask app
# Extremely simple flask application, will display 'Hello World!' on the screen when you run it
# Access it by running it, then going to whatever port its running on (It'll say which port it's running on).
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello, World!'
if __name__ == '__main__':
app.run()
Example 2: post request in python flaks
import json
import requests
api_url = 'http://localhost:5000/create-row-in-gs'
create_row_data = {'id': '1235','name':'Joel','created_on':'27/01/2018','modified_on':'27/01/2018','desc':'This is Joel!!'}
print(create_row_data)
r = requests.post(url=api_url, json=create_row_data)
print(r.status_code, r.reason, r.text)
Server:
from flask import Flask,jsonify,request,make_response,url_for,redirect
import requests, json
app = Flask(__name__)
url = 'https://hooks.zapier.com/hooks/catch/xxxxx/yyyyy/'
@app.route('/create-row-in-gs', methods=['GET','POST'])
def create_row_in_gs():
if request.method == 'GET':
return make_response('failure')
if request.method == 'POST':
t_id = request.json['id']
t_name = request.json['name']
created_on = request.json['created_on']
modified_on = request.json['modified_on']
desc = request.json['desc']
create_row_data = {'id': str(t_id),'name':str(t_name),'created-on':str(created_on),'modified-on':str(modified_on),'desc':str(desc)}
response = requests.post(
url, data=json.dumps(create_row_data),
headers={'Content-Type': 'application/json'}
)
return response.content
if __name__ == '__main__':
app.run(host='localhost',debug=False, use_reloader=True)
Example 3: get post request data flask
@app.route('/form-example', methods=['GET', 'POST']) #allow both GET and POST requests
def form_example():
if request.method == 'POST': #this block is only entered when the form is submitted
language = request.form.get('language')
framework = request.form['framework']
return '''<h1>The language value is: {}</h1>
<h1>The framework value is: {}</h1>'''.format(language, framework)
return '''<form method="POST">
Language: <input type="text" name="language"><br>
Framework: <input type="text" name="framework"><br>
<input type="submit" value="Submit"><br>
</form>'''
Example 4: flask sending post request
#make a POST request
import requests
dictToSend = {'question':'what is the answer?'}
res = requests.post('http://localhost:5000/tests/endpoint', json=dictToSend)
print 'response from server:',res.text
dictFromServer = res.json()
