|
|
|
|
```bash
|
2022-04-28 11:01:05 +00:00
|
|
|
|
# 安装VPC服务包
|
|
|
|
|
cd huaweicloudsdkvpc-${version}
|
2021-02-27 10:37:46 +00:00
|
|
|
|
python setup.py install
|
2022-04-28 11:01:05 +00:00
|
|
|
|
```
|
2020-06-15 07:04:23 +00:00
|
|
|
|
|
2022-04-28 11:01:05 +00:00
|
|
|
|
### 云服务集合包
|
|
|
|
|
|
|
|
|
|
您可以安装`huaweicloudsdkall`,这么做会安装所有SDK支持的服务包:
|
|
|
|
|
|
|
|
|
|
- 使用 pip 安装
|
|
|
|
|
|
2022-07-14 08:55:18 +00:00

|
pip install huaweicloudsdkall
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- 使用源码安装
|
|
|
|
|
|
2022-07-14 08:55:18 +00:00

## 代码示例
|
2020-06-15 07:04:23 +00:00
|
|
|
|
|
2021-02-27 10:37:46 +00:00
|
|
|
|
- 使用如下代码同步查询指定 Region 下的 VPC 清单,实际使用中请将 `VpcClient` 替换为您使用的产品/服务相应的 `{Service}Client`。
|
2023-11-09 09:11:11 +00:00
|
|
|
|
- 认证用的ak和sk直接写到代码中有很大的安全风险,建议在配置文件或者环境变量中密文存放,使用时解密,确保安全。
|
|
|
|
|
- 本示例中的ak和sk保存在环境变量中,运行本示例前请先在本地环境中配置环境变量`HUAWEICLOUD_SDK_AK`和`HUAWEICLOUD_SDK_SK`。

华为云服务存在两种部署方式,Region 级服务和 Global 级服务。
|
|
|
|
|
|
|
|
|
|
Global 级服务有 BSS、DevStar、EPS、IAM、RMS、TMS。
|
|
|
|
|
|
2022-07-07 13:49:54 +00:00
|
|
|
|
Region 级服务使用 BasicCredentials 初始化,需要提供 projectId 。
|
|
|
|
|
|
|
|
|
|
Global 级服务使用 GlobalCredentials 初始化,需要提供 domainId 。
|
2021-02-27 10:37:46 +00:00
|
|
|
|
|
2022-07-14 08:55:18 +00:00
|
|
|
|
客户端认证方式支持以下几种:
|
|
|
|
|
|
|
|
|
|
- 永久 AK&SK 认证
|
|
|
|
|
- 临时 AK&SK&SecurityToken 认证
|
|
|
|
|
- IdpId&IdTokenFile 认证
|
|
|
|
|
|
|
|
|
|
#### 2.1 使用永久 AK 和 SK [:top:](#用户手册-top)

|
2021-02-27 10:37:46 +00:00
|
|
|
|
# Region级服务
|
2023-11-16 09:47:10 +00:00
|
|
|
|
ak = os.getenv("HUAWEICLOUD_SDK_AK")
|
|
|
|
|
sk = os.getenv("HUAWEICLOUD_SDK_SK")
|
2023-11-09 09:11:11 +00:00
|
|
|
|
project_id = "{your projectId string}"
|
|
|
|
|
|
2021-02-27 10:37:46 +00:00
|
|
|
|
basic_credentials = BasicCredentials(ak, sk, project_id)
|
|
|
|
|
|
|
|
|
|
# Global级服务
|
2023-11-16 09:47:10 +00:00
|
|
|
|
ak = os.getenv("HUAWEICLOUD_SDK_AK")
|
|

global_credentials = GlobalCredentials(ak, sk, domain_id)
|
|
|
|
|
```
|
|
|
|
|
|
2021-03-16 13:12:01 +00:00

##### 2.4.3 实例元数据 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
从实例元数据获取临时AK/SK和securitytoken,关于元数据获取请参阅:[元数据获取](https://support.huaweicloud.com/usermanual-ecs/ecs_03_0166.html)
|
|
|
|
|
|
|
|
|
|
手动获取实例元数据认证信息:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from huaweicloudsdkcore.auth.provider import MetadataCredentialProvider
|
|
|
|
|
|
|
|
|
|
# basic
|
|
|
|
|
basic_provider = MetadataCredentialProvider.get_basic_credential_metadata_provider()
|
|
|
|
|
basic_cred = basic_provider.get_credentials()
|
|
|
|
|
|
|
|
|
|
# global
|
|
|
|
|
global_provider = MetadataCredentialProvider.get_global_credential_metadata_provider()
|
|
|
|
|
global_cred = global_provider.get_credentials()
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
##### 2.4.4 认证信息提供链 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
在创建服务客户端,未显式指定认证信息时,按照顺序 **环境变量 -> 配置文件 -> 实例元数据** 尝试加载认证信息
|
|
|
|
|
|
|
|
|
|
通过提供链获取认证信息:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from huaweicloudsdkcore.auth.provider import CredentialProviderChain
|
|
|
|
|
|
|
|
|
|
# basic
|
|
|
|
|
basic_chain = CredentialProviderChain.get_basic_credential_provider_chain()
|
|
|
|
|
basic_cred = basic_chain.get_credentials()
|
|
|
|
|
|
|
|
|
|
# global
|
|
|
|
|
global_chain = CredentialProviderChain.get_global_credential_provider_chain()
|
|
|
|
|
global_cred = global_chain.get_credentials()
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
支持自定义认证信息提供链:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from huaweicloudsdkcore.auth.provider import CredentialProviderChain, ProfileCredentialProvider, MetadataCredentialProvider
|
|
|
|
|
|
|
|
|
|
providers = [
|
|
|
|
|
ProfileCredentialProvider.get_basic_credential_profile_provider(),
|
|
|
|
|
MetadataCredentialProvider.get_basic_credential_metadata_provider()
|
|
|
|
|
]
|
|
|
|
|
|
|
|
|
|
chain = CredentialProviderChain(providers)
|
|
|
|
|
credentials = chain.get_credentials()
|
|
|
|
|
```

#### 3.2 指定 Region 方式 **(推荐)** [:top:](#用户手册-top)
|
|
|
|
|
|
2022-07-14 08:55:18 +00:00

|
# 初始化客户端认证信息,使用当前客户端初始化方式可不填 project_id/domain_id
|
|
|
|
|
# 以初始化 GlobalCredentials 为例
|
2023-11-16 09:47:10 +00:00
|
|
|
|
ak = os.getenv("HUAWEICLOUD_SDK_AK")
|

# 初始化指定云服务的客户端 {Service}Client
|
|
|
|
|
# 以初始化 Global 级服务 IAM 的 IamClient 为例
|
2021-02-27 10:37:46 +00:00
|

.with_http_config(config) \
|
|
|
|
|
.with_credentials(global_credentials) \

|
|
|
|
.build()
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
**说明:**
|
|
|
|
|
|
|
|
|
|
- 指定 Region 方式创建客户端的场景,支持自动获取用户的 projectId 或者 domainId,初始化认证信息时可无需指定相应参数。
|
2021-03-16 13:12:01 +00:00
|
|
|
|
|
|
|
|
|
- **不适用**于 `多ProjectId` 的场景。
|
|
|
|
|
|
|
|
|
|
- 当前支持指定 Region 方式初始化客户端的 region_id : af-south-1, ap-southeast-1, ap-southeast-2, ap-southeast-3, cn-east-2, cn-east-3,
|
|
|
|
|
cn-north-1, cn-north-4, cn-south-1, cn-southwest-2, ru-northwest-2。调用其他 region 可能会抛出 `Unsupported regionId` 的异常信息。
|
|
|
|
|
|
|
|
|
|
**两种方式对比:**
|
|
|
|
|
|
|
|
|
|
| 初始化方式 | 优势 | 劣势 |
|
|
|
|
|
| :---- | :---- | :---- |
|
|
|
|
|
| 指定云服务 Endpoint 方式 | 只要接口已在当前环境发布就可以成功调用 | 需要用户自行查找并填写 projectId 和 endpoint
|
|
|
|
|
| 指定 Region 方式 | 无需指定 projectId 和 endpoint,按照要求配置即可自动获取该值并回填 | 支持的服务和 region 有限制
|
|

通过yaml文件配置,默认会从用户主目录下读取region配置文件,linux为`~/.huaweicloud/regions.yaml`,windows为`C:\Users\USER_NAME\.huaweicloud\regions.yaml`,默认配置文件可以不存在,但是如果配置文件存在且内容格式不对会解析错误抛出异常。
|
|
|
|
|
|
|
|
|
|
可以通过配置环境变量`HUAWEICLOUD_SDK_REGIONS_FILE`来修改默认文件的路径,如`HUAWEICLOUD_SDK_REGIONS_FILE=/tmp/my_regions.yml`
|
|
|
|
|

request = ListVpcsRequest(limit=1)
|
|
|
|
|
# 原始响应Json
|
|
|
|
|
response = client.list_vpcs(request)
|
|
|
|
|
print(response)
|
|
|
|
|
# 响应对象
|
|
|
|
|
response_obj = response.to_json_object()
|
|
|

在某些场景下可能对业务发出的 HTTP 请求进行 Debug ,需要看到原始的 HTTP 请求和返回信息,SDK 提供监听器功能来获取原始的为加密的 HTTP 请求和返回信息。
|
|
|
|
|
|
|
|
|
|
> :warning: Warning: 原始信息打印仅在 Debug 阶段使用,请不要在生产系统中将原始的 HTTP 头和 Body 信息打印到日志,这些信息并未加密且其中包含敏感数据,例如所创建虚拟机的密码,IAM 用户的密码等;当 Body 体为二进制内容,即 Content-Type 标识为二进制时,Body 为"***",详细内容不输出。

### 7. 接口调用器 [:top:](#用户手册-top)

|
|
|
|
|
#### 7.1 自定义请求头 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
可以根据需要灵活地配置请求头域参数,非必要**请勿**指定诸如`Host`、`Authorization`、`User-Agent`、`Content-Type`等通用请求头,可能会导致接口调用错误。

#### 7.2 请求重试 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
`v3.1.97`版本起支持请求重试,需要配置以下参数:
|
|
|
|
|
|
|
|
|
|
- 重试条件:根据上一次请求的响应或异常来判断是否重试
|
|
|
|
|
- 最大重试次数:当符合重试条件时的最大重试次数,指定范围[1, 10]
|
|
|
|
|
- 重试策略:计算每次重试前的等待时间(毫秒)
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
