|
|
|
## 环境准备
|
|
|
* PHP 5.3+
|
|
|
您可以通过`php -v`命令查看当前的 PHP 版本。
|
|
|
* cURL 扩展
|
|
|
您可以通过`php -m`命令查看 cURL 扩展是否已经安装好。
|
|
|
|
|
|
>- Ubuntu 系统中，您可以使用 apt-get 包管理器安装 PHP 的 cURL 扩展，安装命令如下。
|
|
|
```
|
|
|
sudo apt-get install php-curl
|
|
|
```
|
|
|
>- CentOS 系统中，您可以使用 yum 包管理器安装 PHP 的 cURL 扩展。
|
|
|
```
|
|
|
sudo yum install php-curl
|
|
|
```
|
|
|
|
|
|
## SDK 安装
|
|
|
SDK 安装有三种方式：
|
|
|
* Composer 方式
|
|
|
* Phar 方式
|
|
|
* 源码方式
|
|
|
|
|
|
### Composer 方式
|
|
|
推荐使用 Composer 安装 cos-php-sdk-v5，Composer 是 PHP 的依赖管理工具，允许您声明项目所需的依赖，然后自动将它们安装到您的项目中。
|
|
|
> 您可以在 [Composer 官网](https://getcomposer.org/) 上找到更多关于如何安装 Composer，配置自动加载以及用于定义依赖项的其他最佳实践等相关信息。
|
|
|
|
|
|
#### 安装步骤：
|
|
|
1. 打开终端。
|
|
|
2. 下载 Composer，执行以下命令。
|
|
|
```
|
|
|
curl -sS https://getcomposer.org/installer | php
|
|
|
```
|
|
|
3. 创建一个名为`composer.json`的文件，内容如下。
|
|
|
```
|
|
|
{
|
|
|
"require": {
|
|
|
"qcloud/cos-sdk-v5": "1.*"
|
|
|
}
|
|
|
}
|
|
|
```
|
|
|
4. 使用 Composer 安装，执行以下命令。
|
|
|
```
|
|
|
php composer.phar install
|
|
|
```
|
|
|
使用该命令后会在当前目录中创建一个 vendor 文件夹，里面包含 SDK 的依赖库和一个 autoload.php 脚本，方便在项目中调用。
|
|
|
5. 通过 autoloader 脚本调用 cos-php-sdk-v5。
|
|
|
```
|
|
|
require '/path/to/sdk/vendor/autoload.php';
|
|
|
```
|
|
|
|
|
|
现在您的项目已经可以使用 COS 的 V5 版本 SDK 了。
|
|
|
|
|
|
### Phar 方式
|
|
|
Phar 方式安装 SDK 的步骤如下：
|
|
|
1. 在 [GitHub 发布页面](https://github.com/tencentyun/cos-php-sdk-v5/releases) 下载相应的 phar 文件。
|
|
|
2. 在代码中引入 phar 文件：
|
|
|
```
|
|
|
require '/path/to/cos-sdk-v5.phar';
|
|
|
```
|
|
|
|
|
|
### 源码方式
|
|
|
源码方式安装 SDK 的步骤如下：
|
|
|
1. 在 [GitHub 发布页面](https://github.com/tencentyun/cos-php-sdk-v5/releases) 下载相应的 zip 文件。
|
|
|
2. 解压通过 autoload.php 脚本加载 SDK：
|
|
|
```
|
|
|
require '/path/to/sdk/vendor/autoload.php';
|
|
|
```
|
|
|
|
|
|
## 快速入门
|
|
|
可参照 Demo 程序，详见 [sample.php](https://github.com/tencentyun/cos-php-sdk-v5/blob/master/sample.php)。
|
|
|
|
|
|
## 接口文档
|
|
|
php sdk 接口文档，详见https://cloud.tencent.com/document/product/436/12267
|
|
|
|
|
|
### 配置文件
|
|
|
```php
|
|
|
$cosClient = new Qcloud\Cos\Client(array('region' => '<Region>',
|
|
|
'credentials'=> array(
|
|
|
'secretId' => '<SecretId>',
|
|
|
'secretKey' => '<SecretKey>')));
|
|
|
```
|
|
|
|
|
|
若您使用 [临时密钥](https://cloud.tencent.com/document/product/436/14048) 初始化，请用下面方式创建实例。
|
|
|
|
|
|
```
|
|
|
$cosClient = new Qcloud\Cos\Client(array('region' => '<Region>',
|
|
|
'credentials'=> array(
|
|
|
'secretId' => '<SecretId>',
|
|
|
'secretKey' => '<SecretKey>',
|
|
|
'token' => '<XCosSecurityToken>')));
|
|
|
```
|
|
|
|
|
|
### 上传文件
