Krótkie wprowadzenie do Javy dla sprzedawców
Zadbaj o dobrą organizację dzięki kolekcji
Zapisuj i kategoryzuj treści zgodnie ze swoimi preferencjami.
Postępuj zgodnie z instrukcjami z tego krótkiego przewodnika, a za około 10 minut będziesz mieć prostą aplikację wiersza poleceń w języku Java, która wysyła żądania do interfejsu API resellera do rejestracji bez interwencji człowieka.
Wymagania wstępne
Aby skorzystać z tego krótkiego wprowadzenia, musisz mieć:
Krok 1. Włącz interfejs API rejestracji typu zero-touch
- Użyj tego kreatora, aby utworzyć lub wybrać projekt w Konsoli programistów Google i automatycznie włączyć interfejs API. Kliknij kolejno Dalej i Przejdź do danych logowania.
- Ustaw opcję Do jakich danych będziesz uzyskiwać dostęp? na Dane aplikacji.
- Kliknij Dalej. Pojawi się prośba o utworzenie konta usługi.
- Podaj opisową nazwę w polu Nazwa konta usługi.
- Zapisz identyfikator konta usługi (wygląda jak adres e-mail), ponieważ będziesz go później używać.
- Ustaw Rola na Konta usługi > Użytkownik kont usługi.
- Aby zakończyć tworzenie konta usługi, kliknij Gotowe.
- Kliknij adres e-mail utworzonego przez Ciebie konta usługi.
- Kliknij **Klucze**.
- Kliknij kolejno **Dodaj klucz** i **Utwórz nowy klucz**.
- W polu **Typ klucza** wybierz **JSON**.
- Kliknij Utwórz, a klucz prywatny zostanie pobrany na komputer.
- Kliknij **Zamknij**.
- Przenieś plik do katalogu roboczego i zmień jego nazwę na
service_account_key.json.
Krok 2. Połącz konto usługi
- Otwórz portal rejestracji typu zero-touch. W razie potrzeby zaloguj się.
- Kliknij settings_ethernet Konta usługi.
- Kliknij add Połącz konto usługi.
- Ustaw Adres e-mail na adres utworzonego przez siebie konta usługi.
- Aby używać konta usługi z kontem do rejestracji bez interwencji człowieka, kliknij Połącz konto usługi.
Krok 3. Przygotuj projekt
Aby skonfigurować projekt Gradle, wykonaj te czynności:
Uruchom to polecenie, aby utworzyć nowy projekt w katalogu roboczym:
gradle init --type basic
mkdir -p src/main/java src/main/resources
Skopiuj plik service_account_key.json pobrany w kroku 1 do utworzonego wcześniej katalogu src/main/resources/.
Otwórz domyślny plik build.gradle i zastąp jego zawartość tym kodem:
apply plugin: 'java'
apply plugin: 'application'
mainClassName = 'ResellerQuickstart'
sourceCompatibility = 1.7
targetCompatibility = 1.7
version = '1.0'
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.api-client:google-api-client:1.30.11'
compile 'com.google.apis:google-api-services-androiddeviceprovisioning:+'
compile 'com.google.oauth-client:google-oauth-client-jetty:+'
}
Krok 4. Skonfiguruj próbkę
Utwórz plik o nazwie src/main/java/ResellerQuickstart.java, skopiuj do niego podany niżej kod i zapisz go. Wstaw własny identyfikator partnera sprzedawcy jako wartość pola PARTNER_ID (pierwszy wiersz aplikacji).

Identyfikator partnera
Wywołania interfejsu API zwykle wymagają podania identyfikatora partnera jako argumentu. Aby znaleźć identyfikator partnera w portalu rejestracji typu zero-touch:
- Otwórz portal. W razie potrzeby zaloguj się.
- Kliknij settings_ethernet Konta usługi.
- Skopiuj numer identyfikatora partnera z wiersza Identyfikator sprzedawcy.
Krok 5. Uruchom kod
Uruchom skrypt w pliku za pomocą systemu operacyjnego. Na komputerach z systemem UNIX i Mac uruchom w terminalu to polecenie:
gradle -q run

If you haven't onboarded yet, follow the steps in *Get started* in the [Reseller portal guide](/zero-touch/guides/portal).\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: Link the service account\n--------------------------------\n\n1. Open the zero-touch enrollment [portal](https://enterprise.google.com/android/zero-touch/resellers). You might need to sign in.\n2. Click settings_ethernet **Service\n accounts**.\n3. Click add **Link service account**.\n4. Set **Email address** to the address of the service account you created.\n5. Click **Link service account** to use the service account with your zero-touch enrollment account.\n\nStep 3: 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` file you downloaded in Step 1 into the\n `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 apply plugin: 'java'\n apply plugin: 'application'\n\n mainClassName = 'ResellerQuickstart'\n sourceCompatibility = 1.7\n targetCompatibility = 1.7\n version = '1.0'\n\n repositories {\n mavenCentral()\n }\n\n dependencies {\n compile 'com.google.api-client:google-api-client:1.30.11'\n compile 'com.google.apis:google-api-services-androiddeviceprovisioning:+'\n compile 'com.google.oauth-client:google-oauth-client-jetty:+'\n }\n\nStep 4: Set up the sample\n-------------------------\n\nCreate a file named `src/main/java/ResellerQuickstart.java` and copy in the\nfollowing code and save the file.

To find your\npartner ID from the zero-touch enrollment portal, follow the steps below:\n\n1. Open the [portal](https://enterprise.google.com/android/zero-touch/resellers). You might need to sign in.\n2. Click settings_ethernet **Service\n accounts**.\n3. Copy your partner ID number from the **Your reseller ID** line.\n\nStep 5: Run the sample\n----------------------\n\nUse your operating system's help to run the script in the file. On UNIX and Mac\ncomputers, run the command below in your terminal: \n\n gradle -q run\n\nTroubleshooting\n---------------\n\n\n[Tell us what went wrong]() with the quickstart and we'll work to\nfix it.
