情景是这样的,页面有个ajax请求,服务端返回的json数据是较大,一般都是10mb左右。为了节省服务器流量以及节约带宽,需要后端的php将json数据压缩后传输到前端,前端javascript对其进行解压后处理。
目前尝试过的情况如下:
1、使用base64,但是压缩比率较小,只有百分之二十多。
2、用php支持的gzdeflate和gzcompress函数,在javascript端没找到相应的解压库,git上面的一些inflate.js根本使用不了,总是循环过多导致浏览器崩溃。
3、找到javascript支持的一个lzma压缩解压库,很不错,但是没有找到php支持的相关函数。
所以在这里跪求各位大神,是否存在一种压缩方法,使得前后端均可使用该方法压缩与解压,谢谢!

10M也太恐怖了,列表类型建议分页或者滚动加载
服务器端将Response做gzip压缩,我估计10MB的文件大概只会有4MB。
JSON本来的目的就是取代XML,简化网络交互,所以它本身就已经很精简了,如果你们的数据比较大,建议去做数据结构的调整,譬如采用数组来替换key, value的格式。
虽然有替代方案,但是JSON的序列化和反序列化是Native的,如果你使用第三方,就需要配套解码包,想象一下,一个10MB的数据结构,在客户端解码需要耗时多久?

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
