问题描述

有没有一种方法可以将数据从Firebase中检索到Java应用程序?

我有一个Android应用程序,它将数据存储到Firebase数据库中,我需要读取Java应用程序中的数据。我搜索了互联网,但我还没有找到明确的答案。

//不是来自浏览器的URL,是数据库之上的$ <$ p
$ b

  FirebaseOptions options = new FirebaseOptions.Builder()
.setDatabaseUrl(https://database-ff395.firebaseio.com/)
.setServiceAccount(new
FileInputStream(C:/Users/Denisa/Desktop/database-2aab74679b79.json))
.build();
FirebaseApp.initializeApp(options);

DatabaseReference ref = FirebaseDatabase
.getInstance()
.getReference(restricted_access / secret_document);

//这里我尝试引用数据库并在其中添加一个值

 最终FirebaseDatabase数据库= FirebaseDatabase.getInstance(); 
DatabaseReference ref1 = database.getReferenceFromUrl(https://database-ff395.firebaseio.com/database-ff395);
ref1.setValue(ooo);


解决方案

访问Firebase数据库)Firebase文档将JVM视为服务器平台。您可以在中找到所有相关信息。


Is there a way to retrieve data from Firebase to a Java application ?

I have an Android application which stores the data in to a Firebase database and I need to read that data in a Java application. I searched over the Internet, but I have not found a clear answer.

//not the URL from browser, the one above the database

        FirebaseOptions options = new FirebaseOptions.Builder()
            .setDatabaseUrl("https://database-ff395.firebaseio.com/")
            .setServiceAccount(new
      FileInputStream("C:/Users/Denisa/Desktop/database-2aab74679b79.json"))
            .build();
        FirebaseApp.initializeApp(options);

        DatabaseReference ref = FirebaseDatabase
                .getInstance()
                .getReference("restricted_access/secret_document");

//here I try to reference the database and put a value in it

            final FirebaseDatabase database = FirebaseDatabase.getInstance();
            DatabaseReference ref1 = database.getReferenceFromUrl("https://database-ff395.firebaseio.com/database-ff395");
            ref1.setValue("ooo");
解决方案

Accessing the Firebase Database from a regular (non-Android) JVM is considered a server platform by the Firebase documentation. You can find all about it in the Firebase documentation for its server SDKs.
