تطبيق سطر أوامر Java بسيط يُرسل طلبات إلى واجهة برمجة تطبيقات عملاء عملية التسجيل بدون تلامس باستخدام حساب خدمة.
المتطلبات الأساسية
لتشغيل هذه البدء السريع، تحتاج إلى:
- حساب خدمة مرتبط بعميل "إعداد الأجهزة الجوّالة للمؤسّسات دفعةً واحدة"
الحساب. اطّلِع على البدء
.
- Java 1.7 أو إصدار أحدث
- Gradle 2.3 أو إصدار أحدث
- إمكانية الوصول إلى الإنترنت ومتصفّح ويب
الخطوة 1: تفعيل واجهة برمجة التطبيقات لميزة "إعداد الأجهزة الجوّالة للمؤسسات دفعةً واحدة"
- استخدِم هذا
معالج لإنشاء مشروع أو اختياره في Google Developers Console
وتفعيل واجهة برمجة التطبيقات تلقائيًا. انقر على متابعة، ثم على الانتقال إلى بيانات الاعتماد
.
- اضبط ما هي البيانات التي ستتمكّن من الوصول إليها؟ على بيانات التطبيق.
- انقر على التالي. سيُطلب منك إنشاء حساب
خدمة.
- أدخِل اسمًا وصفيًا لـ اسم حساب الخدمة.
- دوِّن رقم تعريف حساب الخدمة (يشبه عنوان بريد إلكتروني) لأنّك
ستحتاج إليه لاحقًا.
- اضبط الدور على حسابات الخدمة > مستخدم حساب الخدمة.
- انقر على تمّ للانتهاء من إنشاء حساب الخدمة.
- انقر على عنوان البريد الإلكتروني لحساب الخدمة الذي أنشأته.
- انقر على **المفاتيح**.
- انقر على **إضافة مفتاح**، ثم انقر على **إنشاء مفتاح جديد**.
- بالنسبة إلى **نوع المفتاح**، اختَر **JSON**.
- انقر على إنشاء وسيتم تنزيل المفتاح الخاص على جهاز الكمبيوتر.
- انقر على **إغلاق**.
- انقل الملف إلى دليل العمل وأعِد تسميته
service_account_key.json
.
الخطوة 2: إعداد المشروع
اتبع الخطوات أدناه لإعداد مشروع Gradle الخاص بك:
نفِّذ الأمر التالي لإنشاء مشروع جديد في دليل العمل:
gradle init --type basic
mkdir -p src/main/java src/main/resources
انسخ service_account_key.json
الذي تم تنزيله عند إنشاء
حساب الخدمة إلى الدليل src/main/resources/
الذي أنشأته أعلاه.
افتح ملف build.gradle
التلقائي واستبدِل محتوياته بالرمز التالي:
apply plugin: 'java'
apply plugin: 'application'
mainClassName = 'CustomerQuickstart'
sourceCompatibility = 1.7
targetCompatibility = 1.7
version = '1.0'
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.api-client:google-api-client:2.2.0'
compile 'com.google.apis:google-api-services-androiddeviceprovisioning:v1-rev20230509-2.0.0'
compile 'com.google.auth:google-auth-library-oauth2-http:1.16.1'
compile 'com.google.auth:google-auth-library-credentials:1.16.1'
compile 'com.google.http-client:google-http-client:1.43.1'
compile 'com.google.oauth-client:google-oauth-client-jetty:1.34.1'
}
الخطوة 3: إعداد العيّنة
أنشئ ملفًا باسم "src/main/java/CustomerQuickstart.java
" وانسخه في
باتباع التعليمات البرمجية وحفظ الملف.

الخطوة 4: تشغيل العيّنة
استخدِم مساعدة نظام التشغيل لتشغيل النص البرمجي في الملف. على نظامي التشغيل UNIX وMac
أجهزة الكمبيوتر، قم بتشغيل الأمر أدناه في الوحدة الطرفية لديك:
gradle -q run

See [Get\n started](/zero-touch/guides/customer/service-accounts).\n- Java 1.7 or greater.\n- [Gradle 2.3 or greater](http://gradle.org/downloads).\n- Access to the internet and a web browser.\n\nStep 1: Turn on the zero-touch enrollment API\n---------------------------------------------\n\n1. Use [this\n wizard](https://console.developers.google.com/start/api?id=androiddeviceprovisioning.googleapis.com) to create or select a project in the Google Developers Console and automatically turn on the API. Click **Continue** , then **Go to credentials**.\n2. Set **What data will you be accessing?** to *Application data*.\n3. Click **Next**. You should be prompted to create a service account.\n4. Give a descriptive name for **Service account name**.\n5. Note the **Service account ID** (it looks like an email address) because you'll use it later.\n6. Set **Role** to *Service Accounts \\\u003e Service Account User*.\n7. Click **Done** to finish creating the service account.\n8. Click the email address for the service account that you created.\n9. Click \\*\\*Keys\\*\\*.\n10. Click \\*\\*Add key\\*\\*, then click \\*\\*Create new key\\*\\*.\n11. For \\*\\*Key type\\*\\*, select \\*\\*JSON\\*\\*.\n12. Click **Create** and the private key downloads to your computer.\n13. Click \\*\\*Close\\*\\*.\n14. Move the file to your working directory and rename it `service_account_key.json`.\n\n| **Warning:** Service account keys can become a security risk if not managed carefully. For advice see [best practices for managing API keys](https://cloud.google.com/iam/docs/best-practices-for-managing-service-account-keys).\n\nStep 2: Prepare the project\n---------------------------\n\nFollow the steps below to set up your Gradle project:\n\n1. Run the following command to create a new project in the working directory:\n\n gradle init --type basic\n mkdir -p src/main/java src/main/resources\n\n2. Copy the `service_account_key.json` you downloaded when you created your\n service account into the `src/main/resources/` directory you created above.\n\n3. Open the default `build.gradle` file and replace its contents with the\n following code:\n\n```carbon\napply plugin: 'java'\napply plugin: 'application'\n\nmainClassName = 'CustomerQuickstart'\nsourceCompatibility = 1.7\ntargetCompatibility = 1.7\nversion = '1.0'\n\nrepositories {\n mavenCentral()\n}\n\ndependencies {\n compile 'com.google.api-client:google-api-client:2.2.0'\n compile 'com.google.apis:google-api-services-androiddeviceprovisioning:v1-rev20230509-2.0.0'\n compile 'com.google.auth:google-auth-library-oauth2-http:1.16.1'\n compile 'com.google.auth:google-auth-library-credentials:1.16.1'\n compile 'com.google.http-client:google-http-client:1.43.1'\n compile 'com.google.oauth-client:google-oauth-client-jetty:1.34.1'\n}\n```\n\nStep 3: Set up the sample\n-------------------------\n\nCreate a file named `src/main/java/CustomerQuickstart.java` and copy in the\nfollowing code and save the file. \n\n```java\nimport com.google.api.client.googleapis.javanet.GoogleNetHttpTransport;\nimport com.google.api.client.http.HttpRequestInitializer;\nimport com.google.api.client.http.HttpTransport;\nimport com.google.api.client.json.JsonFactory;\nimport com.google.api.client.json.gson.GsonFactory;\nimport com.google.api.services.androiddeviceprovisioning.v1.AndroidProvisioningPartner;\nimport com.google.api.services.androiddeviceprovisioning.v1.model.Company;\nimport com.google.api.services.androiddeviceprovisioning.v1.model.CustomerListCustomersResponse;\nimport com.google.api.services.androiddeviceprovisioning.v1.model.CustomerListDpcsResponse;\nimport com.google.api.services.androiddeviceprovisioning.v1.model.Dpc;\nimport com.google.auth.http.HttpCredentialsAdapter;\nimport com.google.auth.oauth2.GoogleCredentials;\nimport com.google.auth.oauth2.ServiceAccountCredentials;\nimport java.io.IOException;\nimport java.io.InputStream;\nimport java.util.Arrays;\nimport java.util.List;\n\n/** This class forms the quickstart introduction to the zero-touch enrollment customer API. */\npublic class CustomerQuickstart {\n\n // A single auth scope is used for the zero-touch enrollment customer API.\n private static final List\u003cString\u003e SCOPES =\n Arrays.asList(\"https://www.googleapis.com/auth/androidworkzerotouchemm\");\n private static final String APP_NAME = \"Zero-touch Enrollment Java Quickstart\";\n\n // Global shared instances\n private static final JsonFactory JSON_FACTORY = GsonFactory.getDefaultInstance();\n private static HttpTransport HTTP_TRANSPORT;\n\n static {\n try {\n HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();\n } catch (Throwable t) {\n t.printStackTrace();\n System.exit(1);\n }\n }\n\n /**\n * Creates a GoogleCredentials object with the correct OAuth2 authorization for the service\n * account that calls the reseller API.
