通过 Java 上传大文件到媒体服务账号报错

  • 项目

问题现象

通过 Java 代码上传文件到媒体服务账号中，若上传的文件过大，则会上传失败。

解决方法

可以选择通过分片的方式进行上传，从而解决该问题，示例代码如下：

// The name of the file as it will exist in your Media Services account.
String fileName = "xxxxxxxx";  
// The local file that will be uploaded to your Media Services account.
InputStream input = new FileInputStream(new File("D:/Test" + fileName));
String blobName = fileName;
// Upload the local file to the asset.
uploader.createBlockBlob(fileName, null);        
String blockId;
byte[] buffer = new byte[1024000];
BlockList blockList = new BlockList();
int bytesRead;        
ByteArrayInputStream byteArrayInputStream;
while ((bytesRead = input.read(buffer)) > 0) 
{
        blockId = UUID.randomUUID().toString();
        byteArrayInputStream = new ByteArrayInputStream(buffer, 0, bytesRead);
        uploader.createBlobBlock(blobName, blockId, byteArrayInputStream);
        blockList.addUncommittedEntry(blockId);
}
uploader.commitBlobBlocks(blobName, blockList);
