FastAPI integratsiyasi

PayTechUZ ni FastAPI ilovalar bilan integratsiya qilish uchun to'liq qo'llanma.

O'rnatish​

PayTechUZ ni FastAPI qo'llab-quvvatlash bilan o'rnating:

pip install paytechuz[fastapi]

Konfiguratsiya​

Ma'lumotlar bazasi modellarini sozlang:

from datetime import datetime, timezone

from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Column, Integer, String, Float, DateTime

from paytechuz.integrations.fastapi import Base as PaymentsBase
from paytechuz.integrations.fastapi.models import run_migrations

# Ma'lumotlar bazasi dvigatelini yaratish
SQLALCHEMY_DATABASE_URL = "sqlite:///./payments.db"
engine = create_engine(SQLALCHEMY_DATABASE_URL)

# Asosiy deklarativ klassni yaratish
Base = declarative_base()

# Order modelini yaratish
class Order(Base):
    __tablename__ = "orders"

    id = Column(Integer, primary_key=True, index=True)
    product_name = Column(String, index=True)
    amount = Column(Float)
    status = Column(String, default="pending")
    created_at = Column(DateTime, default=lambda: datetime.now(timezone.utc))

# run_migrations yordamida to'lov jadvallarini yaratish
run_migrations(engine)

# Order jadvalini yaratish
Base.metadata.create_all(bind=engine)

# Sessiya yaratish
SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=engine)

Webhook ishlovchilarini yaratish:​

from fastapi import FastAPI, Request, Depends

from sqlalchemy.orm import Session

from paytechuz.integrations.fastapi import PaymeWebhookHandler, ClickWebhookHandler


app = FastAPI()

# Ma'lumotlar bazasi sessiyasini olish uchun bog'liqlik
def get_db():
    db = SessionLocal()
    try:
        yield db
    finally:
        db.close()

class CustomPaymeWebhookHandler(PaymeWebhookHandler):
    def successfully_payment(self, params, transaction):
        # Muvaffaqiyatli to'lovni boshqarish
        order = self.db.query(Order).filter(Order.id == transaction.account_id).first()
        order.status = "paid"
        self.db.commit()

    def cancelled_payment(self, params, transaction):
        # Bekor qilingan to'lovni boshqarish
        order = self.db.query(Order).filter(Order.id == transaction.account_id).first()
        order.status = "cancelled"
        self.db.commit()

class CustomClickWebhookHandler(ClickWebhookHandler):
    def successfully_payment(self, params, transaction):
        # Muvaffaqiyatli to'lovni boshqarish
        order = self.db.query(Order).filter(Order.id == transaction.account_id).first()
        order.status = "paid"
        self.db.commit()

    def cancelled_payment(self, params, transaction):
        # Bekor qilingan to'lovni boshqarish
        order = self.db.query(Order).filter(Order.id == transaction.account_id).first()
        order.status = "cancelled"
        self.db.commit()

@app.post("/payments/payme/webhook")
async def payme_webhook(request: Request, db: Session = Depends(get_db)):
    handler = CustomPaymeWebhookHandler(
        db=db,
        payme_id="your_merchant_id",
        payme_key="your_merchant_key",
        account_model=Order,
        account_field='id',
        amount_field='amount'
    )
    return await handler.handle_webhook(request)

@app.post("/payments/click/webhook")
async def click_webhook(request: Request, db: Session = Depends(get_db)):
    handler = CustomClickWebhookHandler(
        db=db,
        service_id="your_service_id",
        merchant_id="your_merchant_id",
        secret_key="your_secret_key",
        account_model=Order
    )
    return await handler.handle_webhook(request)

To'lov uchun havola yaratish​

from paytechuz.gateways.payme import PaymeGateway
from paytechuz.gateways.click import ClickGateway

# Buyurtmani olish
order = db.query(Order).filter(Order.id == 1).first()

# Payme to'lov havolasini yaratish
payme = PaymeGateway(
    payme_id='your_payme_id',
    payme_key='your_payme_key',
    is_test_mode=True  # Ishlab chiqarishda False qiling
)
payme_link = payme.create_payment(
    id=order.id,
    amount=order.amount,
    return_url="https://example.com/return"
)

# Click to'lov havolasini yaratish
click = ClickGateway(
    service_id='your_click_service_id',
    merchant_id='your_click_merchant_id',
    merchant_user_id='your_click_merchant_user_id',
    secret_key='your_click_secret_key',
    is_test_mode=True  # Ishlab chiqarishda False qiling
)
click_link = click.create_payment(
    id=order.id,
    amount=order.amount,
    return_url="https://example.com/return"
)
