将多张图片存储到firebase中并获取网址

Question

我有100张图片需要存储在firebase存储中，但我也需要从中提取网址。有没有一种自动的方式呢？

如果不是有更好的服务提供商，允许上传大量的图像并自动提取网址？

我强烈建议使用Firebase存储和Firebase实时数据库来完成此操作。一些代码来展示如何将这些碎片互动低于（SWIFT）：

共享：

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

上传：

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) 
} 

下载：

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... 
    }) 
})
