將Firebase Admin SDK添加到您的服務器

Node.js

Firebase Admin Node.js SDK在npm上可用。如果您還沒有package.json文件，請通過npm init創建一個文件。接下來，安裝firebase-admin npm軟件包並將其保存到package.json ：

 $ npm install firebase-admin --save
 

要使用該模塊在應用程序中， require從任何JavaScript文件：

 var admin = require('firebase-admin');
 

如果您使用的是ES2015，則可以import模塊：

 import * as admin from 'firebase-admin';

Firebase Admin Java SDK已發佈到Maven中央存儲庫。要安裝該庫，請在build.gradle文件build.gradle其聲明為依賴build.gradle ：

 dependencies {
  implementation 'com.google.firebase:firebase-admin:6.15.0'
}
 

如果使用Maven構建應用程序，則可以將以下依賴項添加到pom.xml ：

 <dependency>
  <groupId>com.google.firebase</groupId>
  <artifactId>firebase-admin</artifactId>
  <version>6.15.0</version>
</dependency>

可通過pip獲得Firebase Admin Python SDK。您可以通過sudo為所有用戶安裝該庫：

 $ sudo pip install firebase-admin
 

或者，您可以通過傳遞--user標誌，僅為當前用戶安裝該庫：

 $ pip install --user firebase-admin

可以使用go get實用程序安裝Go Admin SDK：

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

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

C＃

可以使用.NET軟件包管理器來安裝.NET Admin SDK：

 $ Install-Package FirebaseAdmin -Version 1.15.0
 

或者，使用dotnet命令行實用程序安裝它：

 $ dotnet add package FirebaseAdmin --version 1.15.0
 

或者，您可以通過將以下軟件包引用條目添加到.csproj文件中來進行安裝：

 <ItemGroup>
  <PackageReference Include="FirebaseAdmin" Version="1.15.0" />
</ItemGroup>
