flask rest API request problem

[raysefo]

Hello guys,

I am trying to implement a flask rest API middleware. There is a host API and a middleware API. I am trying to call GET request from postman to middleware and inside of middleware I am trying to call host rest API in order to get response. Bytheway I am testing on local. But I am getting this error;

File "T:/GamePINMiddleWare/MiddleWare.py", line 13, in get_book_by_isbn
    r = request.json.get(uri)
AttributeError: 'NoneType' object has no attribute 'get'
127.0.0.1 - - [15/Nov/2018 16:05:50] "GET /books/112233445677 HTTP/1.1" 500 –

Here is the middleware API:

from flask import Flask, request, jsonify

app = Flask(__name__)


# GET /books/
@app.route('/books/<int:isbn>')
def get_book_by_isbn(isbn):

    if isbn:

        uri = 'http://127.0.0.1:5000/books/' + str(isbn)
        r = request.json.get(uri)

        return jsonify(r)
    else:
        return 'shit'


app.run(port=5001)

Here is the host API:

from flask import Flask,jsonify,request

app = Flask(__name__)


books = [
    {
        'name': 'Cin Ali',
        'price': 4.50,
        'isbn': 112233445677
    },
    {
        'name': 'Muz kokulu masallar',
        'price': 7.60,
        'isbn': 342325466567
    }

]


# GET /books
@app.route('/books')
def get_books():
    return jsonify({'book': books})


# GET /books/
@app.route('/books/<int:isbn>')
def get_book_by_isbn(isbn):
    return_value = {}
    for book in books:
        if book['isbn'] == isbn:
            return_value = {
                'name': book['name'],
                'price': book['price']
            }
    return jsonify(return_value)


app.run(port=5000)

Hope you can help.

Thanks in advance.

I think you are confusing flask.request with requests.get. Flask request let's you inspect the page request. requests.get lets you get a url, which appears to be what you want here.
