rest api parameter in flask - bluefrog - Jun-21-2018
Hi
How can I specify a parameter to task 1.
I have a task list, which is triggered by an integer (1 or 2). But in addition to the integer, I would like to pass in additional parameters, not necessarily number types.
This is what I currently have:
#!/usr/bin/python3
from flask import Flask, jsonify, json
import cx_Oracle
con = cx_Oracle.connect('ordb/ordb@//10.11.12.18:1521/FTNODE')
app = Flask(__name__)
tasks = [
{
'id': 1,
'title': 'Customer list',
'description': 'List of customers currently in the database',
'done': False
},
{
'id': 2,
'title': 'Warehouse List',
'description': 'List of warehouses currently in the database',
'done': False
}
]
@app.route('/warehouse/api/v1.0/api', methods=['GET'])
def get_tasks():
return jsonify({'tasks': tasks})
@app.route('/warehouse/api/v1.0/api/<int:task_id>', methods=['GET'])
def get_task(task_id):
task = [task for task in tasks if task['id'] == task_id]
if len(task) == 0:
abort(404)
print(task_id)
if task_id==1:
c = con.cursor()
query = 'select * from customer'
result = list(c.execute(query))
c.close()
jsonData = json.dumps(result)
print(task_id)
if task_id==2:
c = con.cursor()
query = 'select * from warehouse'
result = list(c.execute(query))
c.close()
jsonData = json.dumps(result)
return jsonify({'task': jsonData})
if __name__ == '__main__':
app.run(port=5001,debug=False)
con.close()Sample output:$ curl -i http://127.0.0.1:5001/warehouse/api/v1.0/api/1

get_task is just a function. You can pass any arguments you want to it along with the task id.

Perhaps I should've been somewhat clearer.
My question related to the url.
Could I for example have something like this?
@app.route('/warehouse/api/v1.0/api/<int:task_id>/<string:some_value>', methods=['GET'])In other words, what types can I have as arguments ?

Can make a quick test like this.
As it are now only float works.
from flask import Flask
app = Flask(__name__)
# @app.route('/hello/<name>') # Default string
# @app.route('/hello/<int:name>')
@app.route('/hello/<float:name>')
def hello(name):
print(type(name))
return f'Hello {name}'
if __name__ == '__main__':
app.run(debug=True)Output:http://127.0.0.1:5000/hello/3.14
<class 'float'> # printed to shell
Hello 3.14
