Fügen Sie das Firebase Admin SDK zu Ihrem Server hinzu

Node.js

Das Firebase Admin Node.js SDK ist auf npm verfügbar. Wenn Sie noch keine package.json Datei haben, erstellen Sie eine über npm init . Installieren Sie als Nächstes das npm-Paket firebase-admin und speichern Sie es in Ihrer package.json :

npm install firebase-admin --save

Um das Modul in Ihrer Anwendung zu verwenden, require es von einer beliebigen JavaScript-Datei an:

const { initializeApp } = require('firebase-admin/app');

Wenn Sie ES2015 verwenden, können Sie das Modul import :

import { initializeApp } from 'firebase-admin/app';

Java

Das Firebase Admin Java SDK wird im zentralen Maven-Repository veröffentlicht. Um die Bibliothek zu installieren, deklarieren Sie sie als Abhängigkeit in Ihrer build.gradle Datei:

dependencies {
  implementation 'com.google.firebase:firebase-admin:9.1.1'
}

Wenn Sie Ihre Anwendung mit Maven erstellen, können Sie Ihrer pom.xml die folgende Abhängigkeit hinzufügen:

<dependency>
  <groupId>com.google.firebase</groupId>
  <artifactId>firebase-admin</artifactId>
  <version>9.1.1</version>
</dependency>

Python

Das Firebase Admin Python SDK ist über pip verfügbar. Sie können die Bibliothek für alle Benutzer über sudo installieren:

sudo pip install firebase-admin

Oder Sie können die Bibliothek nur für den aktuellen Benutzer installieren, indem Sie das Flag --user übergeben:

pip install --user firebase-admin

Gehen

Das Go Admin SDK kann mit dem Dienstprogramm go get installiert werden:

# Install as a module dependency
go get firebase.google.com/go/v4

# Install to $GOPATH
go get firebase.google.com/go

C#

Das .NET Admin SDK kann mit dem .NET-Paketmanager installiert werden:

Install-Package FirebaseAdmin -Version 2.3.0

Installieren Sie es alternativ mit dem dotnet Befehlszeilendienstprogramm:

dotnet add package FirebaseAdmin --version 2.3.0

Oder Sie können es installieren, indem Sie Ihrer .csproj Datei den folgenden Paketreferenzeintrag hinzufügen:

<ItemGroup>
  <PackageReference Include="FirebaseAdmin" Version="2.3.0" />
</ItemGroup>
