ios - 使用 firebase 生成下载链接

Question

我正在创建一个允许用户上传图像然后在文本字段中显示直接链接的应用程序。

这是负责将图像上传到我的存储桶的代码，它在用户按下上传按钮时触发。

    @IBAction func upload(_ sender: Any) {

    let imageContained = viewimage.image

    let storage = Storage.storage()
    var storageRef = storage.reference()
    storageRef = storage.reference(forURL: "bucket link")

    var data = NSData()
    data = UIImageJPEGRepresentation(imageContained!, 0.8)! as NSData
    let dateFormat = DateFormatter()
    dateFormat.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
    let imageName = dateFormat.string(from: NSDate() as Date)
    let imagePath = "images/\(imageName).jpg"

    let mountainsRef = storageRef.child(imagePath)

    let metadata = StorageMetadata()
    metadata.contentType = "image/jpeg"

    mountainsRef.putData(data as Data, metadata: metadata)

我如何为用户生成直接链接？

Answer 1

使用下面这个函数

 func uploadProfilePic(){
        var data = NSData()
        data = UIImageJPEGRepresentation(ivProfile.image!, 0.8)! as NSData
        // set upload path
        let filePath = "\(userid)" // path where you wanted to store img in storage
        let metaData = FIRStorageMetadata()
        metaData.contentType = "image/jpg"

        self.storageRef = FIRStorage.storage().reference()
        self.storageRef.child(filePath).put(data as Data, metadata: metaData){(metaData,error) in
            if let error = error {
                print(error.localizedDescription)
                return
            }else{
                //store downloadURL
                let downloadURL = metaData!.downloadURL()!.absoluteString

            }
        }

    }
