从 Firebase 存储 Xamarin 获取图像下载 url [英] Get image download url from firebase storage Xamarin

问题描述

我正在尝试从上传到 firebase 存储的照片中获取图像 url，以便我可以将对该图像的引用存储在另一个表中，这将允许我能够在整个应用程序的其他地方显示该图像.

Im trying to get the image url from a photo I uploaded to firebase storage so I can store the reference to the image in another table which will allow me to be able to display the image elsewhere throughout the app.

我现在有

private void UploadPhoto()
    {

        if (filePAth != null)
        {
            progressDialog = new ProgressDialog(this);
            progressDialog.SetTitle("Uploading...");
            progressDialog.Window.SetType(Android.Views.WindowManagerTypes.SystemAlert);
            progressDialog.Show();

            var images = storageRef.Child("images/" + Guid.NewGuid().ToString());
            images.PutFile(filePAth)
                .AddOnProgressListener(this)
                .AddOnSuccessListener(this)
                .AddOnFailureListener(this);
        }            
    }


public async void OnSuccess(Java.Lang.Object result)
    {

        try
        {
            var newImageDetails = storageRef.Child("images" + "/" + filePAth);
            Photo photos = new Photo();
            photos.categoryName = spinner.SelectedItem.ToString();
            photos.photoId = newImageDetails.Name;
            photos.ImageUrl = storageRef.DownloadUrl.ToString();
            photos.tagName = addTag.Text;

            if (user != null)
            {
                var uid = user.Uid;
                //set the users id to the category
                photos.uid = uid;
            }

            var firebase = new FirebaseClient(FirebaseURL);
            var item = await firebase.Child("photos").PostAsync(photos);
        }
}

storageref.DownloadUrl 没有给我正确的网址这就是我要找的

The storageref.DownloadUrl does not give me the correct url This is what I am looking for

推荐答案

我在调试模式下找到了解决方案

I got a solution in debugging mode

我看到了 downloadurl 的属性并找到了 Scheme 和 SchemeSpecificPart

i saw the downloadurl's properties and found the Scheme and SchemeSpecificPart

方案 = https"

Scheme = "https"

SchemeSpecificPart = "//firebasestorage.googleapis.com/v0/b/maplog-e4ba5.appspot.com/o/-L0AMbihF23YKxsL1uss?alt=media&token=5c7ccef1-c857-4982-a2fa280ff-a2888所以这是我的代码:

SchemeSpecificPart = "//firebasestorage.googleapis.com/v0/b/maplog-e4ba5.appspot.com/o/-L0AMbihF23YKxsL1uss?alt=media&token=5c7ccef1-c857-4982-a288-fded2f0ff1aa" so here is my code:

void IOnSuccessListener.OnSuccess(Java.Lang.Object result)
{
    var snapShot = (UploadTask.TaskSnapshot)result;
    string imgUrl = snapShot.DownloadUrl.Scheme 
    + ":" 
    + snapShot.DownloadUrl.SchemeSpecificPart;
}

它有效！我一直在寻找解决方案:((但我终于自己找到了XD

and it works! i was looking for the solution :(( but i finally found it myself XD
