将照片上传到 firebase 存储后如何下载 link

Question

我试过像这样下载 URL，但下载不正确 URL。我是 Firebase 初学者，我该怎么做？

Answer 1

您可以在上传文件后获取您的下载路径，如下所示（您需要在您的引用对象（getDownloadUrl）上调用第二个方法）：

    profilePicUploadTask = fileRef.putFile(imgUrl).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() 
    {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot)
        {
             // note: you can get the download path only after the file is uploaded successfully. 
             // To get the download path you have to call another method like follows:
             fileRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() 
             {
                @Override
                public void onSuccess(Uri uri) 
                {
                   // uri is your download path
                }
        }
    });

Answer 2

你可以这样下载URL

fileRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {

     @Override
     public void onSuccess(Uri uri) {
        final Uri download_url = uri;
     }
}):
