將多張圖片存儲到firebase中並獲取網址

Question

我有100張圖片需要存儲在firebase存儲中，但我也需要從中提取網址。有沒有一種自動的方式呢？

如果不是有更好的服務提供商，允許上傳大量的圖像並自動提取網址？

我強烈建議使用Firebase存儲和Firebase實時數據庫來完成此操作。一些代碼來展示如何將這些碎片互動低於（SWIFT）：

共享：

// Firebase services 
var database: FIRDatabase! 
var storage: FIRStorage! 
... 
// Initialize Database, Auth, Storage 
database = FIRDatabase.database() 
storage = FIRStorage.storage() 

上傳：

let fileData = NSData() // get data... 
let storageRef = storage.reference().child("myFiles/myFile") 
storageRef.putData(fileData).observeStatus(.Success) { (snapshot) in 
    // When the image has successfully uploaded, we get it's download URL 
    // This "extracts" the URL, which you can then save to the RT DB 
    let downloadURL = snapshot.metadata?.downloadURL()?.absoluteString 
    // Write the download URL to the Realtime Database 
    let dbRef = database.reference().child("myFiles/myFile") 
    dbRef.setValue(downloadURL) 
} 

下載：

let dbRef = database.reference().child("myFiles") 
dbRef.observeEventType(.ChildAdded, withBlock: { (snapshot) in 
    // Get download URL from snapshot 
    let downloadURL = snapshot.value() as! String 
    // Create a storage reference from the URL 
    let storageRef = storage.referenceFromURL(downloadURL) 
    // Download the data, assuming a max size of 1MB (you can change this as necessary) 
    storageRef.dataWithMaxSize(1 * 1024 * 1024) { (data, error) -> Void in 
    // Do something with downloaded data... 
    }) 
})
