php 华为云对象存储安装（ obs 安装）

由于公司所有服务将会转到华为云，因此，以前用到的阿里云 oss 存储都要改为华为云 obs 存储。以下为如何在 laravel 下安装华为云 SDK 。

在项目 composer.json 所在目录执行以下命令

composer require obs/esdk-obs-php

可能遇到问题： guzzlehttp 版本不正确，可以根据提示，添加指定的 guzzlehttp 版本，如下：

composer require "guzzlehttp/guzzle:6.3.0"

monolog 版本不正确，可以根据提示，添加指定 monolog版本

以下为成功安装返回信息：
