Middleware Savollari

Q1. ASP.NET Core’da middleware nima qiladi?
A) Faqatgina HTTP response yaratadi
B) HTTP so‘rovlarini ketma-ket qayta ishlaydi
C) Faqat routing uchun ishlatiladi
D) Faqat xatolarni log qiladi

✔️ To‘g‘ri javob: B

---

Q2. Quyidagi qaysi method keyingi middleware’ni chaqiradi?
A) await next()
B) return;
C) app.Run()
D) context.Response.WriteAsync()

✔️ To‘g‘ri javob: A

---

Q3. Middleware’lar chaqirilish tartibi kodda yozilgan tartibga bog‘liq.
✔️ True

---

Q4. app.Run() dan keyin yozilgan barcha middleware’lar ham ishlaydi.
✔️ False

---

Q5. ASP.NET Core’da middleware pipeline __________ tartibda ishlaydi.
✔️ Javob: ketma-ket (sequential)

---

Q6. Har bir middleware odatda ikkita vazifani bajaradi: so‘rovni qayta ishlash va __________.
✔️ Javob: keyingi middleware’ni chaqirish

Q7. Quyidagi kodda xatoni toping:

app.Use(async context =>
{
    await context.Response.WriteAsync("Hello Middleware");
    await next(); // ❌
});
❌ Xato: next parametr sifatida olinmagan.
  
✅ To‘g‘ri variant:

app.Use(async (context, next) =>
{
    await context.Response.WriteAsync("Hello Middleware");
    await next();
});

Q8. Kodni tahlil qiling:

app.Use(async (context, next) =>
{
    await next();
    await context.Response.WriteAsync("First");
});

app.Use(async (context, next) =>
{
    await context.Response.WriteAsync("Second");
});


❌ Xato: Ikkinchi middleware await next(); chaqirmaydi, shu sabab First hech qachon yozilmaydi.

Q9. Quyidagi kodni bajarsak, / ga so‘rov yuborilganda output nima bo‘ladi?

app.Use(async (context, next) => { await context.Response.WriteAsync("A"); await next(); await context.Response.WriteAsync("C"); });

app.Run(async context => { await context.Response.WriteAsync("B"); });

✔️ Javob: ABC

---

Q10. Quyidagi kodda natija qanday bo‘ladi?

app.Use(async (context, next) => { await context.Response.WriteAsync("X"); });

app.Run(async context => { await context.Response.WriteAsync("Y"); });

✔️ Javob: X (chunki next() chaqirilmagan, Y bajarilmaydi)
