Alibaba Cloud Credentials for PHP 是帮助 PHP 开发者管理凭据的工具。
## 先决条件
您的系统需要满足[先决条件](/docs/zh-CN/0-Prerequisites.md),包括 PHP> = 5.6。 我们强烈建议使用cURL扩展并使用TLS后端编译cURL 7.16.2+。
## 安装依赖
如果已在系统上[全局安装 Composer](https://getcomposer.org/doc/00-intro.md#globally),请直接在项目目录中运行以下内容来安装 Alibaba Cloud Credentials for PHP 作为依赖项:
```
composer require alibabacloud/credentials
```
> 一些用户可能由于网络问题无法安装,可以使用[阿里云 Composer 全量镜像](https://developer.aliyun.com/composer)。
请看[安装](/docs/zh-CN/1-Installation.md)有关通过 Composer 和其他方式安装的详细信息。
## 快速使用
在您开始之前,您需要注册阿里云帐户并获取您的[凭证](https://usercenter.console.aliyun.com/#/manage/ak)。
### 凭证类型
#### AccessKey
通过[用户信息管理][ak]设置 access_key它们具有该账户完全的权限请妥善保管。有时出于安全考虑您不能把具有完全访问权限的主账户 AccessKey 交于一个项目的开发者使用,您可以[创建RAM子账户][ram]并为子账户[授权][permissions]使用RAM子用户的 AccessKey 来进行API调用。
```php
<?php
use AlibabaCloud\Credentials\Credential;
// Chain Provider if no Parameter
$credential = new Credential();
$credential->getAccessKeyId();
$credential->getAccessKeySecret();
// Access Key
$ak = new Credential([
'type' => 'access_key',
'access_key_id' => '<access_key_id>',
'access_key_secret' => '<access_key_secret>',
]);
$ak->getAccessKeyId();
$ak->getAccessKeySecret();
```
#### STS
通过安全令牌服务Security Token Service简称 STS申请临时安全凭证Temporary Security Credentials简称 TSC创建临时安全凭证。
```php
<?php
use AlibabaCloud\Credentials\Credential;
$sts = new Credential([
'type' => 'sts',
'access_key_id' => '<access_key_id>',
'accessKey_secret' => '<accessKey_secret>',
'security_token' => '<security_token>',
]);
$sts->getAccessKeyId();
$sts->getAccessKeySecret();
$sts->getSecurityToken();
```
#### RamRoleArn
通过指定[RAM角色][RAM Role],让凭证自动申请维护 STS Token。你可以通过为 `Policy` 赋值来限制获取到的 STS Token 的权限。
```php
<?php
use AlibabaCloud\Credentials\Credential;
$ramRoleArn = new Credential([
'type' => 'ram_role_arn',
'access_key_id' => '<access_key_id>',
'access_key_secret' => '<access_key_secret>',
'role_arn' => '<role_arn>',
'role_session_name' => '<role_session_name>',
'policy' => '',
]);
$ramRoleArn->getAccessKeyId();
$ramRoleArn->getAccessKeySecret();
$ramRoleArn->getRoleArn();
$ramRoleArn->getRoleSessionName();
$ramRoleArn->getPolicy();
```
#### EcsRamRole
通过指定角色名称,让凭证自动申请维护 STS Token
```php
<?php
use AlibabaCloud\Credentials\Credential;
$ecsRamRole = new Credential([
'type' => 'ecs_ram_role',
'role_name' => '<role_name>',
]);
$ecsRamRole->getRoleName();
// Note: `role_name` is optional. It will be retrieved automatically if not set. It is highly recommended to set it up to reduce requests.
```
#### RsaKeyPair
通过指定公钥Id和私钥文件让凭证自动申请维护 AccessKey。仅支持日本站。
```php
<?php
use AlibabaCloud\Credentials\Credential;
$rsaKeyPair = new Credential([
'type' => 'rsa_key_pair',
'public_key_id' => '<public_key_id>',
'private_key_file' => '<private_key_file>',
]);
$rsaKeyPair->getPublicKeyId();
$rsaKeyPair->getPrivateKey();
```
#### Bearer Token
如呼叫中心(CCC)需用此凭证,请自行申请维护 Bearer Token。
```php
<?php
use AlibabaCloud\Credentials\Credential;
$bearerToken = new Credential([
'type' => 'bearer',
'bearer_token' => '<bearer_token>',
]);
$bearerToken->getBearerToken();
$bearerToken->getSignature();
```
## 默认凭证提供程序链
默认凭证提供程序链查找可用的凭证,寻找顺序如下:
### 1. 环境凭证
程序首先会在环境变量里寻找环境凭证,如果定义了 `ALIBABA_CLOUD_ACCESS_KEY_ID``ALIBABA_CLOUD_ACCESS_KEY_SECRET` 环境变量且不为空,程序将使用他们创建默认凭证。
### 2. 配置文件
> 如果用户主目录存在默认文件 `~/.alibabacloud/credentials` Windows 为 `C:\Users\USER_NAME\.alibabacloud\credentials`),程序会自动创建指定类型和名称的凭证。默认文件可以不存在,但解析错误会抛出异常。 凭证名称不分大小写若凭证同名后者会覆盖前者。不同的项目、工具之间可以共用这个配置文件因为超出项目之外也不会被意外提交到版本控制。Windows 上可以使用环境变量引用到主目录 %UserProfile%。类 Unix 的系统可以使用环境变量 $HOME 或 ~ (tilde)。 可以通过定义 `ALIBABA_CLOUD_CREDENTIALS_FILE` 环境变量修改默认文件的路径。
```ini
[default]
type = access_key # 认证方式为 access_key
access_key_id = foo # Key
access_key_secret = bar # Secret
[project1]
type = ecs_ram_role # 认证方式为 ecs_ram_role
role_name = EcsRamRoleTest # Role Name非必填不填则自动获取建议设置可以减少网络请求。
[project2]
type = ram_role_arn # 认证方式为 ram_role_arn
access_key_id = foo
access_key_secret = bar
role_arn = role_arn
role_session_name = session_name
[project3]
type = rsa_key_pair # 认证方式为 rsa_key_pair
public_key_id = publicKeyId # Public Key ID
private_key_file = /your/pk.pem # Private Key 文件
```
### 3. 实例 RAM 角色
如果定义了环境变量 `ALIBABA_CLOUD_ECS_METADATA` 且不为空,程序会将该环境变量的值作为角色名称,请求 `http://100.100.100.200/latest/meta-data/ram/security-credentials/` 获取临时安全凭证作为默认凭证。
### 自定义凭证提供程序链
可通过自定义程序链代替默认程序链的寻找顺序,也可以自行编写闭包传入提供者。
```php
<?php
use AlibabaCloud\Credentials\Providers\ChainProvider;
ChainProvider::set(
ChainProvider::ini(),
ChainProvider::env(),
ChainProvider::instance()
);
```
