PHP网站开发—网站架构优化性能概念

最开始的网站架构 最初业务量不大，访问量小，此时的架构，应用程序、数据库、文件都部署在一台服务器上，有些甚至仅仅是租用主机空间 1. 应用、数据、文件分离 将应用程序、数据库、文件各自部署在独立的服务器上，并且根据服务器的用途配置不同的硬件，达到最佳的性能效果。 2. 利用缓存改善网站性能 大部分网站访问都遵循28原则,即80%的访问请求，最终落在20%的数据上,所以我们可以对热点数据进行缓存，减少热点数据的访问路径，提高用户体验。缓存实现常见的方式是本地缓存、分布式缓存。当然还有CDN、反向代理。 2.1 本地缓存 本地缓存，顾名思义是将数据缓存在应用服务器本地，可以存在内存中，也可以存在文件，组件。本地缓存的特点是速度快，但因为本地空间有限所以缓存数据量也有限。 2.2 分布式缓存 分布式缓存的特点是，可以缓存海量的数据，并且扩展非常容易，在门户类网站中常常被使用，速度按理没有本地缓存快，常用的分布式缓存是Memcached、Redis。 2.3 反向代理 部署在网站的机房，当用户请求达到时首先访问反向代理服务器，反向代理服务器将缓存的数据返回给用户，如果没有缓存数据才会继续访问应用服务器获取，这样做减少了获取数据的成本。 2.4 CDN 假设我们的服务器都部署在杭州的机房，对于浙江的用户来说访问是较快的，而对于北京的用户访问是较慢的

Using Laravel bootstrap css to style only a section of a page

由 不羁岁月 提交于 2021-01-24 22:26:14
问题 I'm trying to use the default bootstrap css ( app.css ) that ships with Laravel to style a section of my page - specifically, the form section of my registration page. I don't want to include app.css in my html header as it gives me undesired effect on other parts of the page. So I want it to style only my html forms within the page. Currently, I've used either the asset() or HTML::style() methods like this within my form section: @section('form') <style> @import "{{ asset('css/app.css') }}";

Laravel Passport no authentication

问题 I have some strange problems with my laravel app. I have created an authentication system with Passport, I have installed everything as needed but I can't authenticate the user. When I log in it's creating a token correctly and everything seems to work fine, but when I want to add authentication in postman, it's always "Not Authenticated". This is happening with Laravel 8, I have copied everything from my Laravel 7 app and there is working pretty fine. I will provide you with some code. This

Laravel 5.8 - save user emails encrypted

由 China☆狼群 提交于 2021-01-24 11:41:46
问题 I'm looking for a way to encrypt the user emails in the database. Since Encrypt always generates a different string, it fails. So I took sha1. in AuthenticatesUsers I've changed the credentials method to: protected function credentials(Request $request) { return ['email' => sha1(strtolower($request->email)), 'password' => ($request->password)]; } This works great for the login/registration. But there are problems with resetting the password. Resetting the password uses the
