|
|
### 2. 客户端认证信息 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
|
|
|
|
客户端认证可以使用永久 AK&SK 认证,也可以使用临时 AK&SK&SecurityToken 认证。
|
|
|
|
|
|
|
|
|
|
**认证参数说明**:
|
|
|
|
|
|
|
|
|
|
- `ak` 华为云账号 Access Key
|
|
|
|
|
- `sk` 华为云账号 Secret Access Key
|
|
|
|
|
- `project_id` 云服务所在项目 ID ,根据你想操作的项目所属区域选择对应的项目 ID
|
|
|
|
|
- `domain_id` 华为云账号 ID
|
|
|
|
|
- `security_token` 采用临时 AK&SK 认证场景下的安全票据
|
|
|
|
|
|
|
|
|
|
#### 2.1 使用永久 AK 和 SK [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
``` python
|
|
|
|
|
# Region级服务
|
|
|
|
|
basic_credentials = BasicCredentials(ak, sk, project_id)
|
|
|
|
|
|
|
|
|
|
# Global级服务
|
|
|
|
|
global_credentials = GlobalCredentials(ak, sk, domain_id)
|
|
|
|
|
```
|
|
|
|
|
|
2021-03-16 13:12:01 +00:00
|
|
|
|
- `3.0.26-beta` 及以上版本支持自动获取 projectId/domainId ,用户需要指定当前华为云账号的永久 AK&SK 和 对应的 region_id,同时在初始化客户端时配合 `with_region()`
|
2021-02-27 10:37:46 +00:00
|
|
|
|
方法使用,代码示例详见 [3.2 指定Region方式(推荐)](#32-指定-region-方式-推荐-top) 。
|
|
|
|
|
|
|
|
|
|
#### 2.2 使用临时 AK 和 SK [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
首先需要获得临时 AK、SK 和 SecurityToken ,可以从永久 AK&SK 获得,或者通过委托授权获得。
|
|
|
|
|
|
|
|
|
|
- 通过永久 AK&SK 获得可以参考文档:https://support.huaweicloud.com/api-iam/iam_04_0002.html ,对应 IAM SDK
|
|
|
|
|
中的 `CreateTemporaryAccessKeyByToken` 方法。
|

- 通过委托授权获得可以参考文档:https://support.huaweicloud.com/api-iam/iam_04_0101.html ,对应 IAM SDK
|
|
|
|
|
中的 `CreateTemporaryAccessKeyByAgency` 方法。
|
|

|
|
|
|
|
|
临时 AK&SK&SecurityToken 获取成功后,可使用如下方式初始化认证信息:
|
|
|
|
|
|
|
|
|
|
``` python
|
|
|
|
|
# Region级服务
|
|
|
|
|
basic_credentials = BasicCredentials(ak, sk, project_id).with_security_token(security_token)
|
|
|
|
|
|
|
|
|
|
# Global级服务
|
|
|
|
|
global_credentials = GlobalCredentials(ak, sk, domain_id).with_security_token(security_token)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 3. 客户端初始化 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
客户端初始化有两种方式,可根据需要选择下列两种方式中的一种:
|
|
|
|
|
|
|
|
|
|
#### 3.1 指定云服务 Endpoint 方式 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
``` python
|
2021-03-16 13:12:01 +00:00
|
|
|
|
# 指定终端节点,以 VPC 服务北京四的 endpoint 为例
|
|
|
|
|
endpoint = "https://vpc.cn-north-4.myhuaweicloud.com"
|
|
|
|
|
|
|
|
|
|
# 初始化客户端认证信息,需要填写相应 project_id/domain_id,以初始化 BasicCredentials 为例
|
|
|
|
|
basic_credentials = BasicCredentials(ak, sk, project_id)
|
|
|
|
|
|
|
|
|
|
# 初始化指定云服务的客户端 {Service}Client ,以初始化 Region 级服务 VPC 的 VpcClient 为例
|
2021-02-27 10:37:46 +00:00
|
|
|
|
client = VpcClient.new_builder() \
|
|
|
|
|
.with_http_config(config) \
|
|
|
|
|
.with_credentials(basic_credentials) \
|
|
|
|
|
.with_endpoint(endpoint) \
|
|
|
|
|
.build()
|
|
|
|
|
```
|

|
|
|
|
|
2021-02-27 10:37:46 +00:00
|
|
|
|
**说明:**
|
2020-12-24 01:46:02 +00:00
|
|
|
|
|
2021-02-27 10:37:46 +00:00
|
|
|
|
- `endpoint` 是华为云各服务应用区域和各服务的终端节点,详情请查看 [地区和终端节点](https://developer.huaweicloud.com/endpoint) 。
|
2020-06-15 07:04:23 +00:00
|
|
|
|
|
2021-03-16 13:12:01 +00:00
|
|
|
|
- 当用户使用指定 Region 方式无法自动获取 projectId 时,可以使用当前方式调用接口。
|
|
|
|
|
|
2021-02-27 10:37:46 +00:00
|
|
|
|
#### 3.2 指定 Region 方式 **(推荐)** [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
``` python
|
|
|
|
|
# 增加region依赖
|
|
|
|
|
from huaweicloudsdkiam.v3.region.iam_region import IamRegion
|
|
|
|
|
|
2022-07-07 13:49:54 +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
|
2021-02-27 10:37:46 +00:00
|
|
|
|
global_credentials = GlobalCredentials(ak, sk)
|
|
|
|
|
|
2022-07-07 13:49:54 +00:00
|
|
|
|
# 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
|
|
|
|
client = IamClient.new_builder() \
|
|
|
|
|
.with_http_config(config) \
|
|
|
|
|
.with_credentials(global_credentials) \
|
|
|
|
|
.with_region(IamRegion.CN_NORTH_4) \
|
|
|
|
|
.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
|
|
|
|
|
|
2022-06-23 11:11:56 +00:00
|
|
|
|
#### 3.3 自定义配置 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
**注:**3.0.93版本起支持
|
|
|
|
|
|
|
|
|
|
##### 3.3.1 IAM endpoint配置
|
|
|
|
|
|
|
|
|
|
自动获取用户的 projectId 和 domainId 会分别调用统一身份认证服务的 [KeystoneListProjects](https://apiexplorer.developer.huaweicloud.com/apiexplorer/doc?product=IAM&api=KeystoneListProjects) 和 [KeystoneListAuthDomains](https://apiexplorer.developer.huaweicloud.com/apiexplorer/doc?product=IAM&api=KeystoneListAuthDomains) 接口,默认访问的endpoint为 https://iam.myhuaweicloud.com
|
|
|
|
|
|
|
|
|
|
用户可以通过以下两种方式来修改endpoint
|
|
|
|
|
|
|
|
|
|
###### 3.3.1.1 全局级
|
|
|
|
|
|
|
|
|
|
全局范围生效,通过环境变量`HUAWEICLOUD_SDK_IAM_ENDPOINT`指定
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
//linux
|
|
|
|
|
export HUAWEICLOUD_SDK_IAM_ENDPOINT=https://iam.cn-north-4.myhuaweicloud.com
|
|
|
|
|
|
|
|
|
|
//windows
|
|
|
|
|
set HUAWEICLOUD_SDK_IAM_ENDPOINT=https://iam.cn-north-4.myhuaweicloud.com
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
###### 3.3.1.2 凭证级
|
|
|
|
|
|
|
|
|
|
只对单个凭证生效,会覆盖全局配置
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from huaweicloudsdkcore.auth.credentials import BasicCredentials
|
|
|
|
|
|
|
|
|
|
iam_endpoint = "https://iam.cn-north-4.myhuaweicloud.com"
|
|
|
|
|
credentials = BasicCredentials(ak, sk).with_iam_endpoint(iam_endpoint)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
##### 3.3.2 Region配置
|
|
|
|
|
|
|
|
|
|
###### 3.3.2.1 环境变量
|
|
|
|
|
|
|
|
|
|
通过环境变量配置,格式为`HUAWEICLOUD_SDK_REGION_{SERIVCE_NAME}_{REGION_ID}={endpoint}`
|
|
|
|
|
|
|
|
|
|
注:环境变量名全大写,中划线替换为下划线
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
// 以ECS和IoTDA服务为例
|
|
|
|
|
|
|
|
|
|
// linux
|
|
|
|
|
export HUAWEICLOUD_SDK_REGION_ECS_CN_NORTH_99=https://ecs.cn-north-99.myhuaweicloud.com
|
|
|
|
|
export HUAWEICLOUD_SDK_REGION_IOTDA_AP_SOUTHEAST_10=https://iotda.ap-southwest-10.myhuaweicloud.com
|
|
|
|
|
|
|
|
|
|
// windows
|
|
|
|
|
set HUAWEICLOUD_SDK_REGION_ECS_CN_NORTH_99=https://ecs.cn-north-99.myhuaweicloud.com
|
|
|
|
|
set HUAWEICLOUD_SDK_REGION_IOTDA_AP_SOUTHEAST_10=https://iotda.ap-southwest-10.myhuaweicloud.com
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
###### 3.3.2.2 文件配置
|
|
|
|
|
|
|
|
|
|
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`
|
|
|
|
|
|
|
|
|
|
文件内容格式如下:
|
|
|
|
|
|
|
|
|
|
```yaml
|
|
|
|
|
# 服务名不区分大小写
|
|
|
|
|
ECS:
|
|
|
|
|
- id: 'cn-north-10'
|
|
|
|
|
endpoint: 'https://ecs.cn-north-10.myhuaweicloud.com'
|
|
|
|
|
- id: 'cn-north-11'
|
|
|
|
|
endpoint: 'https://ecs.cn-north-11.myhuaweicloud.com'
|
|
|
|
|
IoTDA:
|
|
|
|
|
- id: 'ap-southwest-9'
|
|
|
|
|
endpoint: 'https://iotda.ap-southwest-9.myhuaweicloud.com'
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
###### 3.3.2.3 Region提供链
|
|
|
|
|
|
|
|
|
|
默认查找顺序为 **环境变量 -> 配置文件 -> SDK中已定义Region**,以上方式都找不到region会抛出异常,获取region示例:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from huaweicloudsdkecs.v2.region.ecs_region import EcsRegion
|
|
|
|
|
|
|
|
|
|
region1 = EcsRegion.value_of("cn-north-10")
|
|
|
|
|
region2 = EcsRegion.value_of("cn-north-11")
|
|
|
|
|
```

|
|
### 4. 发送请求并查看响应 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
``` python
|
|
|
|
|
# 初始化请求,以调用接口 ListVpcs 为例
|
|
|
|
|
request = ListVpcsRequest(limit=1)
|
|
|
|
|
|
|
|
|
|
response = client.list_vpcs(request)
|
|
|
|
|
print(response)
|
|
|
|
|
```
|
|
|
|

#### 4.2 获取响应对象 [:top:](#用户手册-top)
|
2020-06-15 07:04:23 +00:00
|
|
|
|
|
2021-02-27 10:37:46 +00:00
|
|
|
|
Python SDK 默认返回的 response 为原始响应的 Json 数据,如果需要获取当前数据对象,可以使用 `to_json_object()` 方法:
|
2020-06-15 07:04:23 +00:00
|
|
|
|
|
2021-02-27 10:37:46 +00:00
|
|
|
|
``` python
|
|
|
|
|
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()
|
|
|
|
|
print(response_obj["vpcs"])
|
|
|
|
|
```

2020-06-30 12:45:36 +00:00
|
|
|
|
|
2021-02-27 10:37:46 +00:00
|
|
|
|
``` python
|
|
|
|

# 初始化异步客户端,以初始化 VpcAsyncClient 为例
|
|
|
|
|
client = VpcAsyncClient.new_builder() \
|

### 6. 故障处理 [:top:](#用户手册-top)
|
|
|
|
|
|
|
|
|
|
SDK 提供 Access 级别的访问日志及 Debug 级别的原始 HTTP 监听器日志,用户可根据需要进行配置。
|
|
|
|
|
|
|
|
|
|
#### 6.1 访问日志 [:top:](#用户手册-top)
|
|
|
|
|
|
2022-07-07 13:49:54 +00:00
|
|
|
|
SDK 支持打印 Access 级别的访问日志,需要用户手动打开日志开关,支持打印到控制台或者指定的文件。
|
|
|
|
|
|
|
|
|
|
初始化指定服务的客户端实例,以 VpcClient 为例:
|
2020-06-15 07:04:23 +00:00
|
|
|
|
|
2020-12-24 01:46:02 +00:00
|
|

2021-02-27 10:37:46 +00:00
|
|
|
|
client = VpcClient.new_builder() \
|
|
|
|
|
.with_http_config(config) \
|
|
|
|
|
.with_credentials(basic_credentials) \
|
|
|
|
|
.with_endpoint(endpoint) \
|
|
|
|
|
.with_file_log(path="test.log", log_level=logging.INFO) \ # 日志打印至文件
|
|
|
|
|
.with_stream_log(log_level=logging.INFO) \ # 日志打印至控制台
|
|
|
|
|
.build()
|
|
|
|
|
```
|
2020-06-15 07:04:23 +00:00
|

|
|
|
|
- `with_file_log` 支持如下配置:
|
|
|
|
|
- `path`:日志文件路径
|
|
|
|
|
- `log_level`:日志级别,默认INFO

|
|
|
|
|
- `log_level`:日志级别,默认INFO
|
2020-06-15 07:04:23 +00:00
|
|
|
|
|
2021-02-27 10:37:46 +00:00
|
|

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。
