developers are sure to be familiar with Base64 coding, and whether or not they have a clear understanding of it is not necessarily. In fact, Base64 is simply no longer easy, and if it's understood or ambiguous, it shouldn't be. About Base64, take a

Talking about Base64 codingI bet you see the word Base64 when you see it, because you used it in the background when you were able to read the article online. If you know something about binary numbers, you can start reading it.Open an email to view

BASE64 is a coding method that is typically used to encode binary data as a writable character form of data. This is a reversible encoding method. The encoded data is a string that contains characters such as A-Z, A-Z, 0-9, +,/a total of 64

Base64 is one of the most common encoding methods used to transmit 8-bit code on the network, base64 requires that each three 8-bit bytes be converted into four 6-bit bytes (3*8 = 4*6 = 24), and then 6-bit bytes be added with two more high 0 values,

Background:There are two main ways to achieve the current mainstream picture tailoring.1:flash operation clipping. 2: Cut with JS and DOM operations.At present, it seems that the cut is mainly through the front-end upload image to the server, and
