Firebase 存储和 Cloud Functions for Firebase 错误

Question

当您通过 Firebase Cloud Functions 删除文件（特别是在本例中为照片）时，一些文件被删除得很好，一些文件保留在 Firebase 存储中。当文件未删除时，我在日志中收到错误消息，错误文本。

Error: read ECONNRESET at exports._errnoException (util.js:1026:11) at TCP.onread (net.js:569:26)
 Error: read ECONNRESET
    at exports._errnoException (util.js:1026:11)
    at TCP.onread (net.js:569:26)

我的代码

  var functions = require('firebase-functions');
const admin = require('firebase-admin');
const gcs = require('@google-cloud/storage')();
admin.initializeApp(functions.config().firebase);


// deleting functions 
exports.userDidDeleted = functions.auth.user().onDelete(event => {
    const user = event.data; // The Firebase user.

    const email = user.email; // The email of the user.
    const displayName = user.displayName; // The display name of the user.
    const userSearchLocationModelPath = '/userSearchLocationModel/' + user.uid;
     console.log('userDidDeleted', userSearchLocationModelPath);
    admin.database().ref(userSearchLocationModelPath).remove();

    // cards

    var cardsRef = admin.database().ref('cards')    
    cardsRef.orderByChild('ownerID').equalTo(user.uid).on("child_added", function(snapshot) {
        console.log('cardsRef', snapshot.key, snapshot.val); 
        const cardRef = '/cards/' + snapshot.key;      
        admin.database().ref(cardRef).remove();
        // location
        admin.database().ref('cardLocation').child(snapshot.key).remove();

        // photo 

          const filePath = 'cardImages/' + snapshot.key + '/mainCardPhoto/' + 'main.jpg';
        const bucket = gcs.bucket('example-example7.appspot.com');
        const file = bucket.file(filePath);
        const pr = file.delete();

    });

});

在咨询了 Jen Person 之后，我更改了代码，它对我有用。

// 删除函数

exports.userDidDeleted = functions.auth.user().onDelete(event => {
    const user = event.data; // The Firebase user.

    const email = user.email; // The email of the user.
    const displayName = user.displayName; // The display name of the user.
    const userSearchLocationModelPath = '/userSearchLocationModel/' + user.uid;
     console.log('userDidDeleted', userSearchLocationModelPath);
    admin.database().ref(userSearchLocationModelPath).remove();

    // cards

    var cardsRef = admin.database().ref('cards')    
    cardsRef.orderByChild('ownerID').equalTo(user.uid).on("child_added", function(snapshot) {
        // there, I queried!
             console.log('cardsRef', snapshot.key, snapshot.val); 
        const cardRef = '/cards/' + snapshot.key;      
        admin.database().ref(cardRef).remove();
        // location
        admin.database().ref('cardLocation').child(snapshot.key).remove();

        // photo 
        const firebasestoragePath = 'firebasestorage.googleapis.com';

        const placeVenuePhotoPath = '' + snapshot.child('photoURLsProperties').child('placeVenuePhoto').val(); 

        if (placeVenuePhotoPath.includes(firebasestoragePath)) {
          const filePath = 'cardImages/' + snapshot.key + '/mainCardPhoto/' + 'main.jpg';
          const bucket = gcs.bucket('example-example7.appspot.com');
         const file = bucket.file(filePath);
          const pr = file.delete();
          return console.log(filePath, "is deleted");
        } else {
          return console.log("card did not have a custom image", snapshot.key);
        }          
      });
