在firebase中存储数组/在firebase中查询多个字符串

var firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_AUTH_DOMAIN",
  databaseURL: "YOUR_DATABASE_URL",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_STORAGE_BUCKET",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID"
};

firebase.initializeApp(firebaseConfig);

var array = [1, 2, 3, 4, 5];

firebase.database().ref('path/to/array').set(array);

var firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_AUTH_DOMAIN",
  projectId: "YOUR_PROJECT_ID",
};

firebase.initializeApp(firebaseConfig);

var array = ["string1", "string2", "string3", "string4", "string5"];

firebase.firestore().collection('collectionName').doc('documentId').set({
  arrayField: array
});

firebase.database().ref('path/to/array').once('value')
  .then(function(snapshot) {
    var array = snapshot.val();
    // 对数组进行处理
  });

firebase.firestore().collection('collectionName').doc('documentId').get()
  .then(function(doc) {
    if (doc.exists) {
      var array = doc.data().arrayField;
      // 对数组进行处理
    }
  });
