在uniapp框架中遇到ReferenceError: Buffer is not defined错误,通常是因为uniapp是基于Vue.js的前端框架,它主要运行在浏览器环境中,而Buffer是Node.js中的一个全局对象,用于处理二进制数据。浏览器环境中并不直接支持Buffer对象,因此会导致这个错误。以下是一些解决这个问题的建议: 理解uniapp框架和Buffer对象: uniap...
可以自行看一下 vue.config、webpack、babel 等文档配置自动注入。或者直接手动引入 buffer 模块。
var hash = fn(Buffer.concat([ipad, data])) return fn(Buffer.concat([opad, hash])) } function hash(alg, key) { alg = alg || 'sha1'; var fn = algorithms[alg]; var bufs = []; var length = 0; if(!fn) error('algorithm:', alg, 'is not yet supported'); return { update:...

For InnoDB tables, ICP is used only for secondary indexes. The goal of ICP is to reduce the number of full-row reads and thereby reduce I/O operations. For InnoDB clustered indexes, the complete record is already read into the InnoDB buffer. Using ICP in this case does not reduce I/O...
