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_token',
|
|
'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` 和 `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()
|
|
);
|
|
```
|
|
