Пытаюсь получить ответ от python в js:
function function() {
fetch(`http://127.0.0.1:8000/file`, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({ id: Id })
})
.then(response => response.json())
.then(data => {
if (data.status === 'confirmed') {
clearInterval(function1); // Остановка запросов
console.log("Получен ответ confirmed от сервера");
document.getElementById("status").textContent = "123";
alert("123");
clearInterval(function1); // Останавливаем проверку
}
})
.catch(error => {
// Обработка ошибки
console.error("123", error);
});
}
Выдает ошибку в консоли браузера:
Access to fetch at 'http://127.0.0.1:8000/check_payment' from origin 'http://localhost' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
python:

Дал только нужные отрывки кода, некоторые переменные и названия изменил.
В терминале выдает:
