невозможно отправить POST-запрос на сервер Heroku, используя python запросов

0 голосов
/ 30 апреля 2020

Итак, я пытаюсь отправить запрос с посторонней программой на мой сайт. это работало хорошо в localhost, но теперь, когда мой сервер размещен на Heroku, это не так. Я использую requests module 

req_id = requests.post('http://admin-monitor.herokuapp.com/computers/verify_login',
                                   json={"MAC address: ": computer_mac_address()})

, конечно, у меня есть дескриптор для этого URL на моем сервере. когда я заглянул в свои журналы, я увидел 500 error без причины 

"POST /computers/verify_login HTTP/1.1" 500 290 "-" "python-requests/2.23.0"

Я сомневаюсь, что это поможет вам, но на всякий случай это обработчик для запроса 

app.route('/computers/verify_login', methods=['POST', 'GET'])
def check_if_user_exists():
    if request.method == 'POST':
        global new_mac_address
        js = request.get_json()
        print(js)
        if js is not None:
            for mac_address in js.values():
                for i in range(len(Todo.query.all())):
                    if mac_address == Todo.query.filter(Todo.id).all()[i].mac_address:
                        print("True!")
                        return str(Todo.query.filter(Todo.id).all()[i].id)
                new_mac_address = mac_address
                print("Not found!")
                return redirect('/computers/add')
        else:
            print("Empty? wtf")
    else:   
        return ""

Я бы изменил запрос POST на: 

req_id = requests.post('http://admin-monitor.herokuapp.com/computers/verify_login',
                               json={"mac_address": computer_mac_address()})

Затем на сервере вы должны извлечь адрес ma c из json. Поэтому я бы заменил: 

for mac_address in js.values():

на 

mac_address = js['mac_address']

После того, как вы разместили журнал ошибок, я вижу, что произошла ошибка базы данных. Существует некоторое несоответствие типов данных, возможно, со столбцом id в таблице todo. Это должно быть целое число.

...
