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: default flask app
from flask import Flask
app = Flask(__name__)
@app.route('/')
def index():
return 'Flask'
Example 4: flask site route
from flask import render_template
@app.route('/hello/')
@app.route('/hello/<name>')
def hello(name=None):
return render_template('hello.html', name=name)
---------------------------------------------------
<!doctype html>
<title>Hello from Flask</title>
{% if name %}
<h1>Hello {{ name }}!</h1>
{% else %}
<h1>Hello, World!</h1>
{% endif %}
Example 5: basic flask app python
#Import Flask, if not then install and import.
import os
try:
from flask import *
except:
os.system("pip3 install flask")
from flask import *
app = Flask(__name__)
@app.route("/")
def index():
return "<h1>Hello World</h1>"
if __name__ == "__main__":
app.run(host="0.0.0.0", port=8080, debug=False)
Example 6: flask app.route
@app.route("/route/to/page")
def what_to_display_when_someone_goes_here():
return("Whatever.")
