使用 Tus 协议恢复文件上传 [英] Resume file uploading using Tus protocol

问题描述

我正在使用 Laravel 开发网站，并且我正在使用 tus-js-client 将文件直接上传到 Vimeo 而无需通过我的服务器.上传工作完美.

I am developing a website using Laravel, and I am using tus-js-client to upload files directly to Vimeo without going through my server. The uploading works perfect.

但是，假设上传达到了 44%，然后用户刷新了浏览器......据我所知，当用户再次开始上传相同的文件时，它应该从 44% 继续上传......但这不会发生它从头开始.

But, lets say the uploading reached 44%, and then the user refreshed the browser... as I understand It should continue uploading from 44% when the user start uploading the same file again.. but that doesn't happen and it start from the beginning.

我认为这是因为当我向 Vimeo 发送 API 请求以获取 upload_link ( 步骤 1 ) 每次用户刷新页面时，它都会给我一个新的 upload_link..

I think this is happening because when I send an API request to Vimeo to get the upload_link ( step 1 ) It will give me a new upload_link every time the user refresh the page..

 // Upload process start 
  var self = this;

  // Send request to server to get (upload.upload_link) from Vimeo API (Step 1)
  var uploadEndPoint = self.getUploadEndPoint();

  // Start uploading ( Step 2 )
  self.uploader = new tus.Upload(file, {
    uploadUrl: uploadEndPoint,
    retryDelays: [0, 1000, 3000, 5000],
    metadata: {
      filename: file.name,
      filetype: file.type
    },
    resume: true,
    uploadSize: file.size,
    onError: function(error) {
      console.log("Failed because: " + error);
    },
    onProgress: function(bytesUploaded, bytesTotal) {
      var percentage = (bytesUploaded / bytesTotal * 100).toFixed(2);
      console.log(bytesUploaded, bytesTotal, percentage + "%");
    },
    onSuccess: function() {
      console.log(
        "Download %s from %s",
        self.uploader.file.name,
        self.uploader.url
      );
    }
  });

处理此问题的最佳方法是什么，以便用户可以继续上传?

What is the best way to handle this, so the user can resume the upload?

推荐答案

我做了什么:

1. 设置 Laravel 后端端点以获取下载链接
2. 对于第一个端点请求，从后端向 Vimeo 发出请求并在后端保存上传链接
3. 对于进一步的请求，检查客户端是否要下载相同的文件(通过名称和大小，或通过哈希)，如果是，则返回保存的上传链接，如果不请求新的

这样做我解决了两个问题:

by doing that i solve two problems:

• 保留上传链接的记录，直到文件未完全上传
• 在服务器上保持我的永久 Vimeo 访问令牌不受损害，仅在客户端发送上传链接
