从 HTTPS 下载图像并上传到 Android Studio 中的 Firebase 存储答案

【问题标题】：Download image from HTTPS and upload to firebase storage in Android Studio从 HTTPS 下载图像并上传到 Android Studio 中的 Firebase 存储
【发布时间】：2021-04-27 06:53:20
【问题描述】：

我需要将我的文件缩略图从网络上传到 Firebase 存储。 URL总是像

https://drive.google.com/thumbnail?authuser=0&sz=w320&id=1086hD9ShV98klN4n3o187V_DdNTzXsiZyPn20nUHBM4

使用 HTTPS，我在执行此操作时遇到了很多麻烦

为了上传到 Firebase 存储，我可以使用位图、inputStream、URL 或本地文件

我尝试了许多不同的库，毕加索，滑翔，...但我总是得到相同的文件未找到错误。从我在这里读到的，我认为这是因为它是 HTTPS

我该怎么做？

谢谢！

编辑：

我尝试按照建议使用 glide 库，但不适用于所有 url，这是我的代码：

// the thmbnail link is combined with the fileId
        String thumbnailLink = "https://drive.google.com/thumbnail?authuser=0&sz=w320&id=" + databasePost.getFileId();
        Log.i("SecondActivity", "thumbnailLink: "+ thumbnailLink );

        String thumbnailId = databasePost.getFileId() + ".png";

        Glide.with(this)
                .asBitmap()
                .load(thumbnailLink)
                .into(new CustomTarget<Bitmap>() {
                    @Override
                    public void onResourceReady(@NonNull Bitmap image, @Nullable Transition<? super Bitmap> transition) {
                        Log.i("SecondActivity", "loadBitmap: resource ready " );

                        String thumbnailId = databasePost.getFileId() + ".png";

                        StorageReference postRef = storage.child("thumbnails").child(thumbnailId);

                        ByteArrayOutputStream baos = new ByteArrayOutputStream();
                        image.compress(Bitmap.CompressFormat.JPEG, 100, baos);
                        byte[] data = baos.toByteArray();

                        UploadTask uploadTask = postRef.putBytes(data);
                        uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                            @Override
                            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                                Log.i("SecondActivity", "saveThumbnailToStorage: success");
                                databasePost.setThumbnailId(thumbnailId);
                              //  saveDataToDatabase(databasePost);
                            }
                        }).addOnFailureListener(new OnFailureListener() {
                            @Override
                            public void onFailure(@NonNull Exception e) {
                                Log.i("SecondActivity", "saveThumbnailToStorage: error: " + e.getLocalizedMessage());
                            }
                        });
                    }

                    @Override
                    public void onLoadCleared(@Nullable Drawable placeholder) {
                    }

                    @Override
                    public void onLoadFailed(@Nullable Drawable errorDrawable) {
                        super.onLoadFailed(errorDrawable);
                        Log.i("SecondActivity", "loadBitmap: error: " + errorDrawable);

                    }
                });

这是我得到的错误：

编辑 2：我尝试添加 android:networkSecurityConfig="@xml/network_security_config" android:usesCleartextTraffic="true">

这是网络安全：

 <?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">drive.google.com</domain>
 </ domain-config>
 </network-security-config>

我有 android 10 和 glide 4.11 版

【问题讨论】：

“我总是遇到同样的文件未找到错误”你能显示minimal code that reproduces the problem that you're asking for our help on吗？这样更有可能有人可以提供帮助。
@FrankvanPuffelen 我按照建议尝试使用 Glide 库并用错误更新了问题

【解决方案1】：

我终于发现了导致这个错误的原因！所以基本上我试图在上传文件后立即上传缩略图，但如果我做了完全相同但上传后一段时间它工作正常。

显然，您必须在上传后等待一段时间，以便缩略图的链接有效，所以现在我使用完全相同的代码通过 glide 上传，但在使用它之前，我等待 10 秒，它工作得很好！

     try {
                TimeUnit.SECONDS.sleep(10);

   String thumbnailLink = "https://drive.google.com/thumbnail?authuser=0&sz=w320&id=" + databasePost.getFileId();
        Log.i("SecondActivity", "thumbnailLink: "+ thumbnailLink );

        String thumbnailId = databasePost.getFileId() + ".png";

        Glide.with(this)
                .asBitmap()
                .load(thumbnailLink)
                .into(new CustomTarget<Bitmap>() {
                    @Override
                    public void onResourceReady(@NonNull Bitmap image, @Nullable Transition<? super Bitmap> transition) {
                        Log.i("SecondActivity", "loadBitmap: resource ready " );

                        String thumbnailId = databasePost.getFileId() + ".png";

                        StorageReference postRef = storage.child("thumbnails").child(thumbnailId);

                        ByteArrayOutputStream baos = new ByteArrayOutputStream();
                        image.compress(Bitmap.CompressFormat.JPEG, 100, baos);
                        byte[] data = baos.toByteArray();

                        UploadTask uploadTask = postRef.putBytes(data);
                        uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                            @Override
                            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                                Log.i("SecondActivity", "saveThumbnailToStorage: success");
                                databasePost.setThumbnailId(thumbnailId);
                              //  saveDataToDatabase(databasePost);
                            }
                        }).addOnFailureListener(new OnFailureListener() {
                            @Override
                            public void onFailure(@NonNull Exception e) {
                                Log.i("SecondActivity", "saveThumbnailToStorage: error: " + e.getLocalizedMessage());
                            }
                        });
                    }

                    @Override
                    public void onLoadCleared(@Nullable Drawable placeholder) {
                    }

                    @Override
                    public void onLoadFailed(@Nullable Drawable errorDrawable) {
                        super.onLoadFailed(errorDrawable);
                        Log.i("SecondActivity", "loadBitmap: error: " + errorDrawable);

                    }
                });

            } catch (InterruptedException e) {
                Log.i("UploadPostActivity", "failure sleep: "+e.getMessage());
                e.printStackTrace();
            }

【解决方案2】：

如果我首先理解正确，那么您在加载图像时会遇到问题。我不确定你指定的 url 是否可以在没有 API 的情况下加载（我无法在浏览器中打开它）

您是否尝试过任何其他图片/网址？

查看错误所在的日志...

您可以使用 Glide 加载位图（工作代码）：

private void loadBitmapByGlide(String imageUrl, String imageName) {
        Glide.with(this)
                .asBitmap()
                .load(imageUrl)
                .into(new CustomTarget<Bitmap>() {
                    @Override
                    public void onResourceReady(@NonNull Bitmap image, @Nullable Transition<? super Bitmap> transition) {
                        //TODO upload image to firebase storage or something else
                        //String imagePath = savePNG(resource, imageName);
                        Toast.makeText(getApplicationContext(), "Image loaded: " + image.getWidth() + "-" + image.getHeight(), Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onLoadCleared(@Nullable Drawable placeholder) {

                    }
                });
    }

gradle 文件

implementation 'com.github.bumptech.glide:glide:4.11.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'

【讨论】：

如果您使用的是 android 9，您可以尝试在 Manifest 中使用 android:usesCleartextTraffic="true" 或使用 network_security_config（搜索更多详细信息）。也可以尝试使用其他 android 版本或手机
我又检查了两个链接，它工作正常，glide 版本 4.11.0 和 compileSdkVersion 30、android 6 和 11
我刚刚上传了我在搜索 network_security_config 后所做的问题，你做了什么才能得到它们？我有安卓 10
我在我的一个应用中使用了张贴方法（上图）和您的链接...
如果您想知道，显然错误是因为链接尚不可用，所以我必须在文件创建后等待一段时间才能访问 thumbnailLink
