如何将文件从浏览器上传到具有node.js，Express和knox的Amazon S3？ [英] How to upload a file from the browser to Amazon S3 with node.js, Express, and knox?

问题描述

我试图找到一些使用node.js，Express和knox的示例代码。

I'm trying to find some example code that utilizes node.js, Express, and knox.

诺克斯的文档只给出了如何上传的明确示例已存储在文件系统中的文件。 https://github.com/learnboost/knox#readme

The docs for Knox only give clear examples of how to upload a file already stored in the file system. https://github.com/learnboost/knox#readme

另外，还有一些简单的教程（即使在Express本身），如何直接上传文件来表达和保存到文件系统。

Additionally, there a number of simple tutorials (even in Express itself) on how to upload files directly to express and save to the file system.

我无法找到的是一个例子，您可以将客户端上传到节点服务器，并将数据直接传输到S3，而不是首先存储在本地文件系统中。

What I'm having trouble finding is an example that lets you upload a client upload to a node server and have the data streamed directly to S3 rather than storing in the local file system first.

有人可以指出一个包含这种信息的要点或其他例子吗？

Can someone point me to a gist or other example that contains this kind of information?

推荐答案

以前的答案涉及上传通过您的node.js服务器，这是低效和不必要的。您的节点服务器不必处理上传的文件的带宽或处理，因为Amazon S3允许从浏览器直接上传

All of the previous answers involve having the upload pass through your node.js server which is inefficient and unnecessary. Your node server does not have to handle the bandwidth or processing of uploaded files whatsoever because Amazon S3 allows uploads direct from the browser.
