上传进度 - 请求 [英] Upload Progress — Request

问题描述

我要使用 请求 上传文件。

I'm uploading a file using Request.

req = request.post url: "http://foo.com", body: fileAsBuffer, (err, res, body) ->
    console.log "Uploaded!"

如何知道实际上上传了多少数据？是否有一些事件可以订阅，或者是否有请求的属性，我可以轮询？

How do I know how much data has actually been uploaded? Is there some event that I can subscribe to or is there a property of the request that I can poll?

如果没有，上传数据的最佳方法是什么，并知道已上传了多少？

If none, what would be the best approach to upload data and know how much has been uploaded?

推荐答案

我发现的是你可以查询请求'的上传进度。

What I found out is that you can poll the request's connection._bytesDispatched property.

例如：

r = request.post url: "http://foo.com", body: fileAsBuffer
setInterval (-> console.log "Uploaded: #{r.req.connection._bytesDispatched}"), 250

注意：如果分别是 r ，poll r.req.connection.socket._bytesDispatched 。

Note: If you were piping to r, poll r.req.connection.socket._bytesDispatched instead.
