要使用ACME库的ClientV2初始化已存在用户并创建订单,你需要先安装ACME库,命令如下:
```
pip install acme
```
然后,你需要导入ACME库的相关模块,以及ACME库的依赖项,命令如下:
```python
import josepy as jose
from acme import client
from acme import messages
from acme.client import ClientV2
from acme.client import BackwardsCompatibleClientV2
from acme.client import ClientNetwork
from acme.client import ClientError
from acme.crypto import jws
from cryptography.hazmat.primitives import serialization
from cryptography.hazmat.primitives.asymmetric import rsa
```
接下来,你需要设置ACME客户端的相关参数,包括ACME服务器的URL,以及你的私钥和公钥等信息,代码如下:
```python
DIRECTORY_URL = 'https://acme-staging-v02.api.letsencrypt.org/directory'
PRIVATE_KEY_FILE = '/path/to/your/private/key/file'
PUBLIC_KEY_FILE = '/path/to/your/public/key/file'
```
然后,你需要读取你的私钥和公钥,代码如下:
```python
with open(PRIVATE_KEY_FILE, 'rb') as f:
private_key = serialization.load_pem_private_key(
f.read(),
password=None,
)
with open(PUBLIC_KEY_FILE, 'rb') as f:
public_key = serialization.load_pem_public_key(f.read())
```
接下来,你需要使用ACME库的ClientV2类初始化已存在用户,代码如下:
```python
directory = messages.Directory.from_json(
client.Client.fetch_directory(ClientNetwork(), DIRECTORY_URL))
client_v2 = ClientV2(directory, ClientNetwork(), key=private_key)
regr = client_v2.new_account(
messages.NewRegistration.from_data(email='you@example.com'))
```
在初始化用户之后,你可以使用ACME库的ClientV2类创建订单,代码如下:
```python
account_key = jws.JWS.sign(
payload=regr,
key=private_key,
alg=jose.RS256,
external_nonce=None,
)
order = client_v2.new_order(
domains=['example.com', 'www.example.com'],
account_key=account_key,
)
```
以上代码中,`domains`参数指定了要申请证书的域名列表。
如果你的私钥和公钥是从命令行生成的,你可以使用以下命令:
生成私钥:
```
openssl genrsa 4096 > private.key
```
生成公钥:
```
openssl rsa -in private.key -pubout > public.key
```
