Method 1 (Extract):

1. Use the server program to send dataCompressionIt is best to add base64 encoding so that ascii text can be obtained, so that it can be easily mixed with other source code of the web page.
2. decompress the data obtained from the client using the js function for subsequent use.
3. Usage angle: Mainly mild encryption: It is troublesome for ordinary people to solve these things.
4. Note: 1. This method is different from automatic compression on the server. The source code can be easily seen on the client. 2. If the compression is not for encryption, the content should preferably be larger than 1000 bytes, otherwise it will not be able to achieve any compression effect.


Method 2 (compression ):

1. First, compress the data using js functions, and then convert the data into base64 code.
2. It's all nonsense to upload the program to the server.
3. Usage: compresses the forms and data submitted by the client and then uploads the data to the server, because the current server-side compression technology does not support upload compression, therefore, this technology has practical value, and can also achieve lightweight encryption of uploaded data.

Note: I have not tested the performance of these functions, so in terms of performance, you need to test the performance before using it.
