按块上传视频文件

ken*_*dds 7 java api upload vimeo scribe

是的,这是一个很长的问题,有很多细节...所以,我的问题是:我如何将上传流式传输到Vimeo？

对于想要在自己的机器上进行复制和调试的人:以下是您需要的东西:

  • 我的代码在这里.
  • 包括此处的Scribe库
  • 拥有一个至少大于10 MB的有效视频文件(mp4)并将其放在目录中C:\test.mp4或将该代码更改为指向您所在的位置.
  • 而已!谢谢你的协助!

大更新:我在这里的代码中留下了一个工作的API Key和Secret for Vimeo .因此,只要您拥有Vimeo帐户,一旦您允许应用程序并输入令牌,所有代码都可以正常工作.只需将该链接中的代码复制到您喜欢的IDE上的项目中,看看是否可以通过我来解决这个问题.我会把奖金交给给我工作代码的人.谢谢!哦,不要指望长期使用这个Key和Secret.一旦这个问题得到解决,我就会删除它.:)

问题概述:问题是当我将最后一块字节发送到Vimeo然后验证上传时,响应返回所有内容的长度只是最后一个块的长度,而不是所有块的组合,因为它应该.

SSCCE注意:我在这里有我的整个SSCCE .我把它放在别的地方,因此它可以是Ç ompilable.是不是很小号园艺(约300线),但希望你发现它是小号精灵包含的,它肯定是一个ê xample!).但是,我在这篇文章中发布了我的代码的相关部分.

这是它的工作原理:当您通过流方法将视频上传到Vimeo时(请参阅此处的上载API文档以进行设置以达到此点),您必须提供一些标题:端点,内容长度和内容类型.文档说它忽略了任何其他标题.您还要为其上传的文件提供字节信息的有效负载.然后签名并发送它(我有一个方法,将使用scribe这样做).

我的问题:当我在一个请求中发送视频时,一切都很有效.我的问题是在我上传几个较大的文件的情况下,我正在使用的计算机没有足够的内存来加载所有的字节信息并将其放入HTTP PUT请求中,因此我必须将其拆分为1 MB段.这是事情变得棘手的地方.该文档提到可以"恢复"上传,所以我试图用我的代码做到这一点,但它不能正常工作.下面,您将看到发送视频的代码.记住我的SSCCE就在这里.

我尝试过的事情:我认为它与Content-Range标题有关...所以这里是我尝试改变Content-Range标题所说的内容......

  • 不向第一个块添加内容范围标头

  • 在内容范围标题中添加前缀(每个标题都包含前一个标题的组合):

    • "字节"
    • "bytes"(抛出连接错误,请参见最底层的错误) - > 文档中显示这是他们正在寻找的内容,但我很确定文档中存在拼写错误,因为他们有他们的"简历"示例中的内容范围标题:1001-339108/339108应该是什么时候1001-339107/339108.是的...
    • "字节%20"
    • "字节"
    • "字节:"
    • "字节="
    • "bytes ="

  • 不向内容范围标头添加任何内容作为前缀

这是代码:

/**

*
* @return whether the video successfully sent
*/
private static boolean sendVideo(String endpoint, File file) throws FileNotFoundException, IOException {
  // Setup File
  long contentLength = file.length();

  FileInputStream is = new FileInputStream(file);
  int bufferSize = 10485760; // 10 MB = 10485760 bytes
  byte[] bytesPortion = new byte[bufferSize];
  int byteNumber = 0;
  int maxAttempts = 1;
  while (is.read(bytesPortion, 0, bufferSize) != -1) {
    String contentRange = Integer.toString(byteNumber);
    long bytesLeft = contentLength - byteNumber;
    System.out.println(newline + newline + "Bytes Left: " + bytesLeft);
    if (bytesLeft < bufferSize) {
      //copy the bytesPortion array into a smaller array containing only the remaining bytes
      bytesPortion = Arrays.copyOf(bytesPortion, (int) bytesLeft);
      //This just makes it so it doesn't throw an IndexOutOfBounds exception on the next while iteration. It shouldn't get past another iteration
      bufferSize = (int) bytesLeft;
    }
    byteNumber += bytesPortion.length;
    contentRange += "-" + (byteNumber - 1) + "/" + contentLengthString;
    int attempts = 0;
    boolean success = false;
    while (attempts < maxAttempts && !success) {
      int bytesOnServer = sendVideoBytes("Test video", endpoint, contentLengthString, "video/mp4", contentRange, bytesPortion, first);

然后代码继续完成上传和设置视频信息(你可以在我的完整代码中看到).

编辑2:尝试从内容范围中删除"%20"并收到此错误进行连接.我必须使用"bytes%20"或者根本不添加"bytes"...

我认为你的问题可能只是这一行的结果:

request.addHeader("Content-Range", "bytes%20" + contentRange);
Run Code Online (Sandbox Code Playgroud)

尝试"bytes%20"简单地替换"bytes "

在您的输出中,您会看到相应的标头内容不正确:

Headers: {
    Content-Length=15125120,
    Content-Type=video/mp4,
    Content-Range=bytes%200-10485759/15125120     <-- INCORRECT
}

关于Content-Range... 的主题

你是对的,一个示例的最终内容块应该有一个范围14680064-15125119/15125120.这是HTTP 1.1规范的一部分.
