    使用 SRI 解决 CDN 劫持

    SRI 简介SRI 全称 Subresource Integrity - 子资源完整性,是指浏览器通过验证资源的完整性(通常从 CDN 获取)来判断其是否被篡改的安全特性。 通过给 link 标签或者 script 标签增加 integrity 属性即可开启 SRI 功能,比如: integrity 值分成两个部分,第一部分指定哈希值的生成算法(sha256、sha384 integrity 值可以包含多个由空格分隔的哈希值,只要文件匹配其中任意一个哈希值,就可以通过校验并加载该资源。上述例子中我使用了 sha256 和 sha384 两张 hash 方案。 浏览器如何处理 SRI当浏览器在 script 或者 link 标签中遇到 integrity 属性之后,会在执行脚本或者应用样式表之前对比所加载文件的哈希值和期望的哈希值。 使用 SRI通过使用 webpack 的 html-webpack-plugin 和 webpack-subresource-integrity 可以生成包含 integrity 属性 script 标签

    敏捷开发下, 由 User Story 中设计: 保证数据一致性的数据库表结构

    过往的数据库设计思维∵强调整体,主要是期望借由所谓的整体,使的数据库设计可保证数据的 Integrity。 但这样的思维,在面向对象的世界里,往往因类设计时,类责任的不明确,而因为对象的存取破坏了数据的 Integrity。所以,数据库设计真正的重点,不在所谓的 “整体”。而在 “明确”。 所以,由各 Story 所分析出的 Entity,Value Object 便可形成与数据表相匹配的数据表结构,以提升数据的 Integrity
