Question

我试图在我的烧瓶应用中创建一个RESTful端点，但是当我尝试点击端点时，它返回：TypeError: organize() takes exactly 1 argument (0 given)。我在chrome中使用Postman来发送请求，并且我已将所有参数都包含为form-data。

代码：

@app.route('/organize', methods = ['POST'])
def organize(request):
    salary = request.form['salary']
    monthly_expenses = 0.0

    ### Get city/state from zip or (if provided) just proceed
    try:
        zipcode = request.form['zipcode']
        citystate = zippo(zipcode)
        citystate = json.loads(citystate)
        city = citystate['city']
        state_abbr = citystate['state_abbr']

    except DoesNotExist:
        city = request.form['city']
        state_abbr = request.form['state']

    ### Car stuff
    paymentsbool = request.form['paymentsbool']
    try:
        cartype = request.form['cartype']
        payments = request.form['payments']
        insurance_year = request.form['insurance']
        insurance = insurance_year / float(12)
    except DoesNotExist:
        trans = request.form['trans']

    ### Cell phone stuff
    cellbool = request.form['cellbool']
    try:
        cell = request.form['cell']
        monthly_expenses = monthly_expenses + cell
    except DoesNotExist:
        pass

    ### Living expenses
    rent = request.form['rent']
    nat = request.form['nat']
    cable = request.form['cable']
    gas = request.form['gas']
    elec = request.form['elec']
    groceries = request.form['groceries']

    monthly_sal = salary / float(12)
    monthly_sal_af_tax = monthly_sal * .72
    monthly_savings = monthly_sal_af_tax * .15

    if request.form['carbool'] == True:
        car_month = car(cartype, payments, insurance)
        monthly_bal = monthly_bal - car_month
        transportation = car_month
    else:
        monthly_bal = monthly_bal - trans
        transportation = trans

    monthly_expenses = monthly_expenses + rent + nat + cable + gas + elec + groceries + transportation
    monthly_bal = monthly_sal_af_tax - monthly_savings - monthly_expenses

    return jsonify(monthly_bal = monthly_bal, transportation = transportation, monthly_sal_af_tax = monthly_sal_af_tax, monthly_savings = monthly_savings, monthly_expenses = monthly_expenses)

def car(type, payments, insurance):
    gas_price = 4.00
    cars = {1:10, 2:15, 3:20}
    tank = cars[type]
    gas_month = 2.00 * tank * gas_price
    car_total = gas_month + payments + insurance

    return car_total

我还想知道你是否使用jsonify返回数据是最好的方法吗？感谢您的帮助，非常感谢。

编辑：我还尝试用curl命中端点，但它返回相同的结果。

curl -X POST -d {‘zipcode’:13905, ‘paymentsbool’:0, ‘trans’:10, ‘cellbool’:0, ‘rent’:20, ‘nat’:30, ‘cable’:40, ‘gas’:50, ‘elec’:60, ‘groceries’:70} http://127.0.0.1:8080/organize --header "Content-Type:application/json"

EDIT2：继续玩这个我已经删除了request参数，以便该函数不带参数。当我尝试curl调用时，它会返回

Answer 1

我无法解释为什么会这样，但我发现通过使用request.values代替request.form，它可以访问正在发送的数据。

我仍然希望解释为什么request.form无法正常工作，但这确实解决了我的问题。
