Python Language Tutorial => The Request Object

Example

The request object provides information on the request that was made to the route. To utilize this object, it must be imported from the flask module:

from flask import request

URL Parameters

In previous examples request.method and request.form were used, however we can also use the request.args property to retrieve a dictionary of the keys/values in the URL parameters.

@app.route("/api/users/<username>")
def user_api(username):
    try:
        token = request.args.get("key")
        if key == "pA55w0Rd":
            if isUser(username): # The code of this method is irrelevant
                joined = joinDate(username) # The code of this method is irrelevant
                return "User " + username + " joined on " + joined
            else:
                return "User not found"
        else:
            return "Incorrect key"
    # If there is no key parameter
    except KeyError:
        return "No key provided"

To correctly authenticate in this context, the following URL would be needed (replacing the username with any username:

www.example.com/api/users/guido-van-rossum?key=pa55w0Rd

File Uploads

If a file upload was part of the submitted form in a POST request, the files can be handled using the request object:

@app.route("/upload", methods=["POST"])
def upload_file():
    f = request.files["wordlist-upload"]
    f.save("/var/www/uploads/" + f.filename) # Store with the original filename

Cookies

The request may also include cookies in a dictionary similar to the URL parameters.

@app.route("/home")
def home():
    try:
        username = request.cookies.get("username")
        return "Your stored username is " + username
    except KeyError:
        return "No username cookies was found")
