ios - 无法使用 iOS Swift API 将图片上传到 Google Firebase 存储

Question

早些时候，我能够将图片上传到 Google Firebase Strage。但突然它不工作了。

代码如下:

private func uploadEmergencyImages(images: [Int: URL], emergencyId: String){
    let imagesRef = Storage.storage().reference().child("incidents").child(emergencyId).child("images")

    if(!images.isEmpty){
        for (key, value) in images {
            print("Image to be Uploaded = \(value.absoluteString)")

            let imageData = try! Data(contentsOf: value)
            //                let image = UIImage(data: imageData)

            let metaData = StorageMetadata()
            metaData.contentType = "image/png"
            imagesRef.child("Image_\(key+1).png").putData(imageData, metadata: metaData) { (storageMetaData, storageError) in
                if(storageError != nil){
                    print("Error - While uploading Image:: \(storageError.debugDescription)")
                }else{
                    print("Upload completed...")
                }
            }
        }
    }
}

下面是错误消息(注意:我在这篇文章中用“XXX”屏蔽了我的 firebasePrjName。)

我也曾尝试修改我的 info.plist 文件，但没有成功:

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
    </dict>

非常感谢任何线索。

这对我有用 (swift 4 代码)

let storageRef = DBProvider.Instance.imageStorageRef.child(user!.uid) // Put Here your Storage Referance  
let imageData = UIImageJPEGRepresentation(youimagehere, 1.0) // put your image Here

storageRef.putData(imageData!, metadata: nil, completion: { (metadata, error) in

    if error == nil
    {
        let path = metadata?.downloadURL()?.absoluteString
        print(path)
    }
})

确保您已从您的 Firebase 项目启用 firebase 存储读、写权限。
