Nodejs Read-Write streamThe transfer process of a stream is transmitted by default in the form of buffer, unless you set him up with another encoded form,For example, in the second part of the code below, we set the stream to be transmitted in UTF8

First, Introduction The functional development described earlier is done by the simple call API, which does not operate on the database. In the next advanced feature development, you need to use the database, so in this article, the MySQL database

The example of this paper describes the Base64 encryption, MD5 encryption and SHA1 encryption implemented by JS. Share to everyone for your reference, specific as follows: 1, Base64 encryption The Base64.js file is introduced into the page, and
