使用 Node.js 发送 HTTP Post form data 数据 - 待注销

在Node.js中有相当多的解决方案，其中有语言内置功能，也有开源社区贡献的开发库。 下面咱们来看一下比较流行的几种方式。

本文介绍了一种使用Node.js的request模块发送包含文件的multipart POST请求的方法。 具体实现涉及利用fs模块读取本地文件，并将文件数据作为formData的一部分进行上传。

In this article, you'll learn how the content type multipart/form-data differs in use from alternative content types, how the FormData interface works, how you can use it to send data to the server, and how you can write a simple server to receive and

以下是一个可以在 Node.js 中运行的完整代码示例，用于执行 HTTP POST 请求。 这个请求发送到 https://blog.net/delarticle 这个 URL，包含指定的表单数据。

Your solution uses the request module which includes support for form data. It would do this for you, if you would allow it, with no new dependencies other than the ones you've already included.
