Question

我正在尝试在解析时上传视频文件。要上传视频，我使用以下代码：

    File inputFile = new File(uri.toString());
    FileInputStream fis = new FileInputStream(inputFile);
    ByteArrayOutputStream bos= new ByteArrayOutputStream();
    byte[] buf = new byte[(int)inputFile.length()];

        for (int readNum; (readNum=fis.read(buf)) != -1;){
            bos.write(buf,0,readNum);
        }
        byte[] bytes = bos.toByteArray();
    ParseFile file = new ParseFile("testVideo1.mp4", bytes);
    ParseObject parseObject = new ParseObject("chat1");
    parseObject.saveInBackground();

但inputfile File对象未转换为FileInputStream。

感谢您的帮助，这帮助我开始上传视频进行解析，我发现了您的问题，只是没有将解析文件放入parseobject中。基本上，您从未发送过视频

File inputFile = new File(uri.toString());
FileInputStream fis = new FileInputStream(inputFile);
ByteArrayOutputStream bos= new ByteArrayOutputStream();
byte[] buf = new byte[(int)inputFile.length()];

    for (int readNum; (readNum=fis.read(buf)) != -1;){
        bos.write(buf,0,readNum);
    }
    byte[] bytes = bos.toByteArray();
ParseFile file = new ParseFile("testVideo1.mp4", bytes);
ParseObject parseObject = new ParseObject("chat1");
//addition
parseObject.put("video",file);
//it should work with this
parseObject.saveInBackground();

如何在android上解析上传视频文件？
