fine-uploader - 我想如果重试到另一个网址后文件上传失败

Question

我在差异位置 1.Upload1.abc.com 2.upload2.abc.com 有多个保管库。如果文件上传失败，我想在 Upload1.abc.com 上发帖，它将重新开始整个过程​​以将文件发布到 Upload2.abc.com

这样文件上传就不会失败。即使一个块再次失败，整个集合也会在运行时上传到下一个后备 url。

Answer 1

这无疑是一种处理失败上传的有趣方式。有没有办法保证1.Upload1.abc.com永远向上？

我会对completeFine Uploader 抛出的事件做出反应。如果responseJSON有一个不是success的属性，则弹出端点堆栈的新端点，发出调用，最后发出调用，以便上传重新开始，如下所示， truesetEndpointretry

var original_endpoints = ['1.Upload1.abc.com', '2.upload2.abc.com']
  , endpoints = original_endpoints;

var fu = new qq.FineUploader({
  // ... Other options
  cors: { 
    expected: true // this *must* be a cross-origin request
  },
  request: {
    endpoint: endpoints.shift() // the original endpoint to be attempted first
   },
  callbacks: {
    onComplete: function (fileId, fileName, responseJSON, xhr) {
        if (responseJSON.success != true) {
          var endpoint = endpoints.shift();
          if (endpoint !== undefined) {
            // Changes endpoint for *all* subsequent uploads
            this.setEndpoint(endpoint); 

            // Or, to change the endpoint for this particular file that failed
            // and try the original endpoint again on the next file,
            // this.setEndpoint(endpoints, fileId);
          } else {
            // This will restart the process by setting the endpoints queue to 
            // its default. Note that you may want to handle the error of all
            // endpoints failing another way, as this just restarts the process
            // and may result in an infinite loop if all endpoints are constantly down.
            endpoints = original_endpoints;
            this.setEndpoint(endpoints.shift());
          }

          this.retry(fileId); // Retry the upload

        }   
    }
  }
});
