火力地堡SignedURL不等於下載地址存儲

Question

從來就問了一個問題，以前從火力地堡的存儲，這是給我的答案得到將downloadURL是：

bucket.file(filename).getSignedUrl({ 
    action: 'read', 
    expires: '03-17-2025' 
}, function(err, url) { 
    if (err) { 
    console.error(err); 
    return; 
    } 

    // The file is now available to read from this URL. 
    request(url, function(err, resp) { 
    // resp.statusCode = 200 
    }); 
}); 

給出的是由以前的一個代碼在使用Glide下載圖像或使用ExoPlayer重新生成音頻或視頻文件時不起作用。

不過，我得到一個完全地不同的URL比由火力地堡存儲給出的，（至極做工作滑翔和ExoPlayer）當一個文件被上傳至極看起來是這樣的：

我怎樣才能得到正確的downloadUrl，就像我在服務器端使用Android或iOS SDK所獲得的那樣？

Answer 1

有沒有辦法讓服務器端的下載網址就像使用Android，iOS或Javascript SDK一樣。你必須通過調用getSignedUrl（）來生成一個url。

您可能想要檢查是否有權讀取給定URL處的文件。

默認情況下，您必須進行身份驗證。

Answer 2

我希望你上傳的圖像通過應用程序只有吶？一旦上傳，你將獲得下載鏈接。我希望這會幫助你。

import com.google.firebase.storage.StorageTask; 

final StorageTask uploadTask = uplodedFileRef.putBytes(data); 
    Log.d(TAG, "uploadFilefromPath: " + uplodedFileRef.getPath().toString()); 
uploadTask.addOnFailureListener(new OnFailureListener() { 
       @Override 
       public void onFailure(@NonNull Exception exception) { 
        // Handle unsuccessful uploads 
        Toast.makeText(acty, "Upload Failed", Toast.LENGTH_SHORT).show(); 
        dialog.dismiss(); 
        sendResult(false, Uri.EMPTY); 
       } 
      }) 
      .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() { 
       @Override 
       public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { 
        // taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL. 
        Toast.makeText(acty, "Upload Successful", Toast.LENGTH_SHORT).show(); 
        dialog.dismiss(); 
        sendResult(true, taskSnapshot.getDownloadUrl()); 
       } 
      }) 
      .addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() { 
       @Override 
       public void onProgress(UploadTask.TaskSnapshot taskSnapshot) { 

        int bytesTransferred = (int) taskSnapshot.getBytesTransferred(); 
        int totalBytes = (int) taskSnapshot.getTotalByteCount(); 
        int progress = (100 * bytesTransferred)/totalBytes; 

        Log.v(TAG, "Bytes transferred: " + taskSnapshot.getBytesTransferred()); 
        Log.v(TAG, "TotalBytes: " + totalBytes); 
        Log.v(TAG, "Upload is: " + progress + "% done"); 

        dialog.setContent("Upload in Progress"); 
        dialog.getProgressBar().setIndeterminate(false); 
        // double progress = (100.0 * taskSnapshot.getBytesTransferred())/taskSnapshot.getTotalByteCount(); 
        dialog.getProgressBar().setMax(totalBytes/1024); 
        dialog.setMaxProgress(totalBytes/1024); 
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { 
         dialog.getProgressBar().setProgress(bytesTransferred/1024, true); 
         dialog.setProgress(bytesTransferred/1024); 
        } else 
         dialog.getProgressBar().setProgress(bytesTransferred/1024); 
        dialog.setProgress(bytesTransferred/1024); 
        // dialog.getProgressBar().setProgress((int) progress); 
       } 
      }); 

Answer 3

addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() { 
     @Override 
     public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { //success 
      sendResult(true, taskSnapshot.getDownloadUrl()); 
     } 
}) 

在這個taskSnapshot.getDownloadUrl()您將收到下載鏈接，然後將其保存火力數據庫可以能夠檢索作爲當
