有哪些压缩类库,使得前端javascript可以针对服务端返回的压缩后的数据进行解压?
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?

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
