Post Method 405 Error

I have a decently intermediate understanding of APIs, and am not trying to host information I've got from APIs onto the web.

This incredibly simple code:

from flask import Flask, request, render_template
import requests

app = Flask(__name__)

@app.route('/temperature', methods=['POST'])
def temperature():
    zipcode = request.form['zip']
    r = requests.get('http://api.openweathermap.org/data/2.5/weather?zip=' +zipcode+',us&appid=9b56b06ab4c7f06821ccf55e3e10fce5')
    json_obj = r.text
    return json_obj

@app.route('/')
def index():
    return 'hi'

if __name__ == '__main__':
    app.run(debug=True)

Is not giving me anything (except the 405 error).

Can someone please explain why my POST method is not working?

I'll post my answer from /r/ flask here, just for posterity.

the line in your code: zipcode = request.form['zip'] implies that you are submitting data from an HTML form to the view via a POST.

If there is no form, then request.form['zip'] does nothing, and is most likely raising the error. Considering that I see no route in your logic there that points to any HTML, I'm guessing that's the issue.

If you have not built a form for the user to submit the zip code, then you could build it into the route logic. For example, you could do:

@app.route('/temperature/<zipcode>')
def temperature(zipcode):
    # add some kind of validation here to make sure it's a valid zipcode
    r = requests.get('http://api.openweathermap.org/data/2.5/weather?zip=' +zipcode+',us&appid=DONT_SHARE_YOUR_API_KEY')
    json_obj = r.text
    return json_obj

You could then use http://127.0.0.1:5000/temperature/20003 to see the data for that zip code.

(as a side note, it's often unwise to publicly share your API keys. you may want to generate a new key.)

While I'm not entirely sure what you have done, here's what I think you did:

You accessed the /temperature page in your browser which is by default a GET-Request.

You then get returned a 405 Method Not Allowed Error, because your route explicitly requires that the page will be accessed via the HTTP-POST Method.

Modify @app.route('/temperature', methods=['POST']) to @app.route('/temperature', methods=['POST', 'GET']) and you should be fine.
