【问题描述】：

我想在我的聊天应用程序的图像视图支架中显示个人资料图片。我已经实现了 google 和 facebook 等 firebase auth 登录方法。所以我想在他们聊天时显示用户图像。我可以通过FirebaseAuth.getInstance().getCurrentUser().getPhotoUrl(); 显示当前用户图像但是当我想获取另一个用户的图像时？所以我尝试了以下方法，

注册应用后，我可以获取他们的个人资料图片并将其上传到 Firebase 存储。之后我可以在应用程序的聊天头中使用它。所以下面是代码

Uri dpUri = currentFirebaseUser.getPhotoUrl();
if (dpUri != null) {
    final ProgressDialog progressDialog = new ProgressDialog(this);
    progressDialog.setTitle("Uploading...");
    progressDialog.show();

    final StorageReference ref = storageReference.child(currentFirebaseUser.getUid());
    ref.putFile(dpUri)
            .addOnSuccessListener(taskSnapshot -> {
                ref.getDownloadUrl().addOnSuccessListener(uri -> databaseReference.child("Users").child(currentFirebaseUser.getUid()).child("URL").setValue(uri.toString()));

                progressDialog.dismiss();

                LocationOn();
            })
            .addOnFailureListener(e -> {
                progressDialog.dismiss();
                Toast.makeText(SignActivity.this, "Failed " + e.getMessage(), Toast.LENGTH_SHORT).show();
            })
            .addOnProgressListener(taskSnapshot -> {
                double progress = (100.0 * taskSnapshot.getBytesTransferred() / taskSnapshot
                        .getTotalByteCount());
                progressDialog.setMessage("Uploaded " + (int) progress + "%");
            });
}

但不可读，我收到此错误：

请帮我修复它或建议我另一种方法来完成我的任务

【问题讨论】：

您应该编辑您的问题，不要提及“Firebase 存储”，因为您实际上只是将用户的配置文件 URL 存储到您的“Firebase 实时数据库”中。

标签： android firebase firebase-realtime-database firebase-storage

【解决方案1】：

您可以通过以下三种方式之一将文件上传到 Firebase 存储：1) 本地文件，2) 字节数组，3) base64 编码的数据字符串。您正在使用图像的 URL 调用 putFile，这是不受支持的。

您将不得不采用两步法：

将数据从 URL 下载到 Android 设备，
然后将数据从 Android 设备上传到 Storage。

另见：

Upload image from URL to Firebase Storage

【讨论】：

【解决方案2】：

我建议您在将个人资料图片上传到 FirebaseStorage 之前执行此操作。

获取在ImageView 上显示的图片网址。
将图像转换为字节。

    val bitmap = (binding.ivPicture.drawable as BitmapDrawable).bitmap
    val baos = ByteArrayOutputStream()
    bitmap.compress(
        Bitmap.CompressFormat.JPEG,
        30,
        baos
    )
    val data = baos.toByteArray()
    // Create file metadata including the content type
    val metadata = storageMetadata {
        contentType = "image/jpeg"
    }

将字节存储到 FirebaseStorage

    val uploadTask = storage.putBytes(data, metadata)
    uploadTask.addOnFailureListener {
        // Handle unsuccessful uploads
        Tools.showToast(
            this,
            "Error uploading image: " + it.message
        )
         
    }.addOnSuccessListener {
        storage.downloadUrl.addOnCompleteListener { task ->
            if (task.isSuccessful) {
                //Get download url to store in the database.
                val profileUrl = task.result.toString()
    
            } else {
    
                Tools.showToast(
                    this,
                    "Error saving: " + task.exception?.message
                )
    
            }
        }
    }

【讨论】：

但是我需要获取firebase auth 图像，我已经知道如何将图像上传到firebase 商店！
@LakpriyaSenevirathna 你误解了这段代码的作用，你将图像从user.getPhotoUrl() 加载到ImageView，然后在第 2 步中，它将缓存的图像存储在视图中并转换它到一个字节数组，然后在第 3 步中将其上传到 Cloud Storage
是的。你的方法也是正确的。在下面访问我的答案！我认为这是最好的方法！

【解决方案3】：

终于找到了解决办法。我做了这样的事情！

 if(currentFirebaseUser.getPhotoUrl()!=null){
     databaseReference.child("Users").child(currentFirebaseUser.getUid()).child("URL").setValue(currentFirebaseUser.getPhotoUrl().toString());
 }

您将在 firebase 数据库中看到图片网址

如果您使用 Google OAuth；

https://lh3.googleusercontent.com/a/AATXAJzFGstrkeyXMQUU9XIKEXIL8jgEgm1T-EKi3AW1=s96-c

如果您删除 =s96-c ，您可以获得高质量的图像！

https://lh3.googleusercontent.com/a/AATXAJzFGstrkeyXMQUU9XIKEXIL8jgEgm1T-EKi3AW1

如果您使用任何其他 Oauth 方法。它工作正常，我尝试了 yahoo Oauth，它将通过currentFirebaseUser.getPhotoUrl().toString() 检索个人资料图片的网址

【讨论】：

重要的是，用户的photoURL 并不总是托管在googleusercontent.com 上，您可能会根据他们的身份验证方式获得Facebook、Twitter 等存储的图像。
@samthecodingman 它也适用于其他 oauth 构建者！我试过雅虎！
