Recently began to learn Nodejs, just have a small need to bring practiced hand. Implement a simple picture server.I used the express framework here.An exception error occurred during debugging when a form was found to post data from the browser side to the Nodejs server. Such as:The error is spelled as follows:So on the Internet query, the final solution is as follows:Hope to have encountered the same mistakes classmates can learn from.Nodejs

Many of the small pits continued to tread. Today, a more common problem is encountered: Picture upload. theme : Picture upload Server, and then pass Aliyun through the server. No nonsense.
