使用swift将图像保存为image/jpeg格式到firebase

import Firebase
import FirebaseStorage

FirebaseApp.configure()

let storage = Storage.storage()
let storageRef = storage.reference()

guard let image = UIImage(named: "your_image_name") else { return }
guard let imageData = image.jpegData(compressionQuality: 0.8) else { return }

let imageName = NSUUID().uuidString

let imageRef = storageRef.child("images/\(imageName).jpg")
let uploadTask = imageRef.putData(imageData, metadata: nil) { (metadata, error) in
    guard let metadata = metadata else {
        // 上传失败处理
        return
    }
    // 上传成功处理
    // 可以从metadata中获取图像的下载URL
    imageRef.downloadURL { (url, error) in
        guard let downloadURL = url else {
            // 获取下载URL失败处理
            return
        }
        // 获取下载URL成功处理
        print(downloadURL.absoluteString)
    }
}
