إنشاء كائن مرجعي للنص البرمجي

يُستخدم الكائن المرجعي لربط ملف تم تحميله بنص برمجي. أنشئ عنصرًا مرجعيًا ضمن الخوارزمية باستخدام طلب uploadScript.

في ما يلي كيفية إنشاء عنصر مرجعي للنص البرمجي:

جافا

// Provide the ID of the advertiser that owns the algorithm.
long advertiserId = advertiser-id;

// Provide the ID of the algorithm.
long customBiddingAlgorithmId = algorithm-id;

// Generate the custom bidding script reference object.
CustomBiddingScriptRef response =
    service
        .customBiddingAlgorithms()
        .uploadScript(customBiddingAlgorithmId)
        .setAdvertiserId(advertiserId)
        .execute();

// Display the generated resource path.
System.out.printf(
    "The generated script reference object provided the following resource path: %s.",
    response.getResourceName());

Python

# Provide the ID of the advertiser that owns the algorithm.
advertiser_id = advertiser-id

# Provide the ID of the algorithm.
algorithm_id = algorithm-id

# Generate a script reference object under the algorithm.
custom_bidding_script_ref = (
    service.customBiddingAlgorithms()
    .uploadScript(
        customBiddingAlgorithmId=algorithm_id, advertiserId=advertiser_id
    )
    .execute()
)

# Print the resource path provided in the generated script reference object.
print(
    "The generated script reference object provided the following resource"
    " path: "

تحميل ملف نص برمجي

استخدِم طلب وسائط upload لتحميل ملف النص البرمجي إلى مسار المورد في الكائن المرجعي. استخدِم عملية تحميل بسيطة مع مَعلمة طلب بحث uploadType=media.

في ما يلي كيفية تحميل ملف نص برمجي:

جافا

// Provide the local path to the script file to upload.
String scriptPath = script-path;

// Provide the resource path to upload the script file to.

إنشاء عنصر نص برمجي

استخدِم طلب create لإنشاء عنصر نص برمجي ضمن الخوارزمية.

إذا كان ملف البرنامج النصي يتضمّن خطأ في البنية، سيفشل طلب create. سيتضمّن الردّ تفاصيل حول الخطأ. أصلِح النص البرمجي وأعِد تشغيل العملية من خلال إنشاء عنصر مرجعي جديد.

حالة نص الاستطلاع

تعالج "مساحة العرض والفيديو 360" النص البرمجي بعد إنشائه. بعد ذلك، تقبل "مساحة العرض والفيديو 360" النص البرمجي لتسجيل نقاط مرات الظهور أو ترفضه.

بعد إنشاء النص البرمجي، أرسِل طلبًا للتأكّد من قبوله. تحقَّق من الحقل state في النص البرمجي الناتج:

  • إذا كانت القيمة PENDING، استمر في طلب البيانات من النص البرمجي.
  • إذا كانت القيمة ACCEPTED، يكون النص البرمجي صالحًا. تابِع التحقّق مما إذا كانت الخوارزمية جاهزة.
  • إذا كانت القيمة REJECTED، يعني ذلك أنّ هناك خطأ في النص البرمجي. استرجِع البيانات في الحقل errors للحصول على قائمة بالأخطاء المحدّدة التي تم العثور عليها في النص البرمجي. يُرجى معالجة الأخطاء وإعادة تشغيل هذه العملية من خلال إنشاء عنصر مرجعي جديد للنص البرمجي لتحميل ملف نص برمجي تم إصلاحه.
