Remember that the following fields need to be submitted when using Baidu Translation API last week.

So, how do I encrypt the sign to MD5 in Vue.js?

(Baidu has many methods to let us install plug-ins, but my Celeron processor can't carry so many plug-ins!!!)

If you don't install plug-ins, you can only write your own code!

The code is a bit long, and the download address of DEMO is also provided at the bottom. You can download it yourself!

usage method:
Hex_md5 ("I want to encrypt the whole eight books that year")
Pass the content to be encrypted into this method, and the return value is the encrypted MD5
