تفاعلات البث

عند إنشاء تفاعل، يمكنك ضبط stream: true لبثّ الاستجابة بشكل تدريجي باستخدام الأحداث التي يرسلها الخادم (SSE).

Python

from google import genai

client = genai.Client()

stream = client.interactions.create(
    model="gemini-3-flash-preview",
    input="Count to from 1 to 25.",
    stream=True,
)
for event in stream:
    if event.event_type == "step.delta":
        if event.delta.type == "text":
            print(event.delta.text, end="", flush=True)

JavaScript

import { GoogleGenAI } from "@google/genai";

const client = new GoogleGenAI({});

const stream = await client.interactions.create({
    model: "gemini-3-flash-preview",
    input: "Count to from 1 to 25.",
    stream: true,
});
for await (const event of stream) {
    if (event.event_type === "step.delta") {
        if (event.delta.type === "text") {
            process.stdout.write(event.delta.text);
        }
    }
}

أنواع الأحداث

يتضمّن كل حدث يرسله الخادم event_type باسم وبيانات JSON مرتبطة. تستخدم Interactions API نموذج بث متماثلًا يتدفق فيه كل المحتوى، مثل النصوص واستدعاءات الأدوات والتفكير، من خلال حدث مستند إلى الخطوات ومتّسق.

يتّبع كل بثّ تدفق الأحداث هذا:

  1. interaction.created: يتم إنشاء التفاعل، ويتضمّن بيانات وصفية (رقم التعريف والنموذج والحالة).
  2. سلسلة من الخطوات، يتكوّن كل منها مما يلي:
    • حدث step.start يشير إلى نوع الخطوة (مثل model_output أو thought أو function_call).
    • حدث واحد أو أكثر من أحداث step.delta تتضمّن بيانات تدريجية لهذه الخطوة.
    • حدث step.stop يضع علامة على الخطوة باعتبارها مكتملة.
  3. حدث interaction.completed يتضمّن إحصاءات usage النهائية.

عند ضبط stream: false، تعرض واجهة برمجة التطبيقات كائن interaction واحدًا يتضمّن مصفوفة steps. كل عنصر في steps هو الإصدار المجمّع بالكامل من دورة step.startstep.delta(s) → step.stop واحدة.

interaction.created

يتم إرسال هذا الحدث عند إنشاء التفاعل لأول مرة. ويحتوي على رقم تعريف التفاعل والنموذج والحالة الأولية.

event: interaction.created
data: {"interaction": {"id": "...", "model": "gemini-3-flash-preview", "status": "in_progress", "object": "interaction"}, "event_type": "interaction.created"}

interaction.status_update

يشير إلى انتقال الحالة على مستوى التفاعل. وقد يظهر بين الخطوات.

event: interaction.status_update
data: {"interaction_id": "...", "status": "in_progress", "event_type": "interaction.status_update"}

step.start

يشير إلى بداية خطوة جديدة. ويحتوي على type وindex للخطوة. يحدّد نوع الخطوة أنواع التغييرات المتوقّعة وكيفية ظهور الخطوة في استجابة غير مستندة إلى البث:

نوع الخطوة أنواع التغييرات المتوقّعة الوصف
model_output text وimage وaudio محتوى الاستجابة النهائية للنموذج
thought thought_signature وthought_summary الاستدلال بسلسلة الأفكار لا يظهر summary إلا عند تفعيل thinking_summaries.
function_call arguments_delta طلب من العميل تنفيذ دالة يتم ضبط حالة التفاعل على requires_action.
أدوات من جهة الخادم تختلف حسب الأداة الأدوات التي تنفّذها واجهة برمجة التطبيقات (مثل google_search_call وgoogle_search_result وcode_execution_call وcode_execution_result)

للاطّلاع على القائمة الكاملة، يُرجى مراجعة مرجع Interactions API.

event: step.start
data: {"index": 0, "step": {"type": "model_output"}, "event_type": "step.start"}

بالنسبة إلى استدعاءات الدوال، تتضمّن الخطوة اسم الدالة ورقم تعريفها والوسيطات الفارغة {}

event: step.start
data: {"index": 0, "step": {"type": "function_call", "id":"un6k8t18", "name": "get_weather", "arguments":{}}, "event_type": "step.start"}

step.delta

بيانات تدريجية للخطوة الحالية يحتوي كائن delta على حقل type يحدّد شكله.

أمثلة:

text: رمز نص تدريجي من خطوة model_output:

event: step.delta
data: {"index": 0, "delta": {"type": "text", "text": "Hello, my name is Phil"}, "event_type": "step.delta"}

event: step.delta
data: {"index": 0, "delta": {"type": "text", "text": ", and I live in Germany." }, "event_type": "step.delta"}

image: بيانات صورة بترميز Base64 من خطوة model_output:

event: step.delta
data: {"index": 0, "delta": {"type": "image", "mime_type": "image/jpeg", "data": "/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAoHBwgHBgoICAgLCg..."}, "event_type": "step.delta"}

thought_summary: محتوى ملخّص التفكير من خطوة thought

event: step.delta
data: {"index": 0, "delta": {"type": "thought_summary", "content": {"type": "text", "text": "I need to find the GCD..."}}, "event_type": "step.delta"}

arguments_delta: سلسلة JSON (جزئية) لوسيطات استدعاء الدالة يجب تجميعها في جميع التغييرات:

event: step.delta
data: {"index": 0, "delta": {"type": "arguments_delta", "arguments": "{\"location\": \"San Francisco, CA\"}"}, "event_type": "step.delta"}

في ما يلي بعض أنواع التغييرات الأكثر شيوعًا. للاطّلاع على القائمة الكاملة بجميع أنواع التغييرات، يُرجى مراجعة مرجع Interactions API.

step.stop

يشير إلى نهاية خطوة ويحتوي على index للخطوة.

event: step.stop
data: {"index": 0, "event_type": "step.stop"}

interaction.completed

يتم إرسال هذا الحدث عند اكتمال التفاعل. ويحتوي على كائن التفاعل النهائي مع إحصاءات usage. في الوضع غير المستند إلى البث، يكون هذا الكائن هو كائن الاستجابة ذو المستوى الأعلى نفسه. لا يتضمّن steps في الاستجابة.

event: interaction.completed
data: {"interaction": {"id": "v1_abc123", "status": "completed", "usage": {"total_input_tokens": 7, "total_output_tokens": 12, "total_tokens": 19}}, "event_type": "interaction.completed"}

error

يتم إرسال هذا الحدث عند حدوث خطأ أثناء التفاعل. ويحتوي على كائن خطأ يتضمّن رسالة ورمزًا.

event: error
data: {"error":{"message":"Deadline expired before operation could complete.","code":"gateway_timeout"},"event_type":"error"}

البث باستخدام الأدوات

تتيح Interactions API البث باستخدام كلّ من الأدوات من جهة العميل (استدعاء الدالة) والأدوات من جهة الخادم (بحث Google وتنفيذ الرموز وما إلى ذلك) في طلب واحد. أثناء البث، تظهر استدعاءات الأدوات كخطوات مكتوبة في بث الأحداث. بالنسبة إلى استدعاءات الدوال، يقدّم حدث step.start اسم الدالة، وتبثّ أحداث step.delta الوسيطات كسلاسل JSON (arguments_delta). عليك تجميع هذه التغييرات للحصول على الوسيطات الكاملة. تنفّذ واجهة برمجة التطبيقات تلقائيًا الأدوات من جهة الخادم، مثل "بحث Google"، ما يؤدي إلى إنشاء خطوات google_search_call وgoogle_search_result.

البث باستخدام استدعاء الدالة

لتنفيذ استدعاء الدالة باستخدام البث، على العميل التعامل مع محادثة مترابطة:

  1. الدور الأول (طلب الدالة): استدعِ interactions.create مع stream: true وtools التي حدّدتها. ستبثّ واجهة برمجة التطبيقات خطوة function_call. عليك تجميع سلاسل JSON للوسيطات التدريجية (arguments_delta) من أحداث step.delta إلى أن يكتمل التفاعل بالحالة requires_action.
  2. الدور الثاني (إرسال النتيجة): استدعِ interactions.create مرة أخرى، مع تمرير previous_interaction_id (الذي يطابق رقم تعريف التفاعل الأول) وإرسال كتلة function_result ضمن مصفوفة input. يؤدي ذلك إلى استئناف البث، ما يسمح للنموذج بإنشاء استجابته النهائية.

البث مع التفكير

عندما يستخدم النموذج التفكير، ستتلقّى thought خطوات تتضمّن نوعَين مختلفَين من التغييرات: thought_summary (محتوى ملخّص نصي أو صورة تدريجي) وthought_signature (تمثيل مشفّر للاستدلال الداخلي للنموذج، يتم إرساله كآخر تغيير قبل step.stop). إذا كانت thinking_summaries مفعّلة، تبثّ تغييرات thought_summary ملخّصًا لاستدلال النموذج. لمزيد من التفاصيل عن التفكير، يُرجى الاطّلاع على دليل التفكير.

البث باستخدام الوكلاء

تتيح Interactions API استخدام الوكلاء، مثل Deep Research. يستخدم الوكلاء background=True ويعرضون النتائج بشكل غير متزامن، ولكن يمكنك أيضًا بثّ تفاعلات الوكيل لتلقّي آخر الأخبار عن التقدّم والخطوات الوسيطة أثناء حدوثها. لمزيد من التفاصيل، يُرجى الاطّلاع على دليل Deep Research.

البث لإنشاء الصور

تتيح Interactions API بثّ أوضاع إخراج متعددة في وقت واحد. من خلال طلب كلّ من text وimage في response_format، يمكنك تلقّي نصوص وصور منشأة متداخلة في البث نفسه.

يستخدم المثال التالي gemini-3.1-flash-image-preview (Nano Banana 2) للبحث عن معلومات وإنشاء قصة تتضمّن رسومًا توضيحية متداخلة.

Python

    response_format=[

التعامل مع الأحداث غير المعروفة

وفقًا لسياسة تحديد الإصدارات في واجهة برمجة التطبيقات، قد تتم إضافة أنواع جديدة من الأحداث والتغييرات بمرور الوقت. يجب أن يتعامل الرمز البرمجي مع أنواع الأحداث غير المعروفة بشكل سليم، أي تسجيل أي أحداث لا تتعرّف عليها وتخطّيها بدلاً من عرض خطأ.

الخطوات التالية
