32.1 企業網路配置
32.1.1 代理服务器配置
HTTP/HTTPS 代理
Claude Code 支援標準的環境變數來配置代理伺服器：
python
# HTTPS 代理（推荐）
export HTTPS_PROXY=<https://proxy.example.com:8080>
# HTTP 代理（如果 HTTPS 不可用）
export HTTP_PROXY=<http://proxy.example.com:8080>
# 代理白名单（不通过代理的地址）
export NO_PROXY="localhost 127.0.0.1 192.168.1.1 example.com .example.com"
### 代理配置管理器
bash
python
class ProxyConfigManager:
"""代理配置管理器"""
def __init__(self):
self.config = {
'https_proxy': None,
'http_proxy': None,
'no_proxy': [],
'proxy_auth': None
}
def configure(self, proxy_settings: Dict) -> ConfigResult:
"""配置代理"""
result = ConfigResult()
# 设置 HTTPS 代理
if 'https_proxy' in proxy_settings:
self.config['https_proxy'] = proxy_settings['https_proxy']
os.environ['HTTPS_PROXY'] = self.config['https_proxy']
result.add_setting('HTTPS_PROXY', self.config['https_proxy'])
# 设置 HTTP 代理
if 'http_proxy' in proxy_settings:
self.config['http_proxy'] = proxy_settings['http_proxy']
os.environ['HTTP_PROXY'] = self.config['http_proxy']
result.add_setting('HTTP_PROXY', self.config['http_proxy'])
# 设置白名单
if 'no_proxy' in proxy_settings:
no_proxy_list = ' '.join(proxy_settings['no_proxy'])
self.config['no_proxy'] = proxy_settings['no_proxy']
os.environ['NO_PROXY'] = no_proxy_list
result.add_setting('NO_PROXY', no_proxy_list)
# 验证配置
validation = self._validate_config()
result.validation = validation
return result
def _validate_config(self) -> ValidationResult:
"""验证配置"""
validation = ValidationResult()
# 检查代理 URL 格式
for proxy_type in ['https_proxy', 'http_proxy']:
proxy_url = self.config.get(proxy_type)
if proxy_url:
if not self._is_valid_url(proxy_url):
validation.add_error(
f"Invalid {proxy_type} URL: {proxy_url}"
)
# 测试代理连接
if self.config.get('https_proxy'):
if not self._test_proxy_connection(self.config['https_proxy']):
validation.add_error(
"Cannot connect to HTTPS proxy"
)
return validation
def _is_valid_url(self, url: str) -> bool:
"""验证 URL 格式"""
try:
result = urllib.parse.urlparse(url)
return all([result.scheme, result.netloc])
except Exception:
return False
def _test_proxy_connection(self, proxy_url: str) -> bool:
"""测试代理连接"""
try:
parsed = urllib.parse.urlparse(proxy_url)
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(5)
result = sock.connect_ex((parsed.hostname, parsed.port or 8080))
sock.close()
return result == 0
except Exception:
return False
### 代理身份验证
#### 基本身份验证
# 在代理 URL 中包含凭据
export HTTPS_PROXY=http://username:password@proxy.example.com:8080
export HTTP_PROXY=http://username:password@proxy.example.com:8080
#### NTLM/Kerberos 认证對於需要高階身份驗證的代理，建議使用 LLM 閘道器：
python
bash
bash
# 配置 LLM 网关处理代理认证
export ANTHROPIC_BASE_URL=https://llm-gateway.company.com
export ANTHROPIC_AUTH_TOKEN=gateway-token
### 代理配置最佳实践
## 32.1.2 自定义 CA 证书
### 配置自定义 CA
企业环境通常使用自定义证书颁发机构（CA）来签发内部证书。Claude Code 需要配置以信任这些 CA：
# 配置自定义 CA 证书
export NODE_EXTRA_CA_CERTS=/path/to/ca-cert.pem
# 或使用多个证书
export NODE_EXTRA_CA_CERTS=/path/to/ca1.pem:/path/to/ca2.pem
### CA 证书管理器
bash
python
class CACertificateManager:
"""CA 证书管理器"""
def __init__(self):
self.certificates = []
self.certificate_store = '/etc/ssl/certs'
def add_certificate(self, cert_path: str) -> CertResult:
"""添加 CA 证书"""
result = CertResult()
# 验证证书
if not self._validate_certificate(cert_path):
result.success = False
result.error = "Invalid certificate"
return result
# 复制证书到存储
cert_name = os.path.basename(cert_path)
dest_path = os.path.join(self.certificate_store, cert_name)
shutil.copy(cert_path, dest_path)
self.certificates.append(dest_path)
# 更新环境变量
self._update_ca_bundle()
result.success = True
result.certificate_path = dest_path
return result
def _validate_certificate(self, cert_path: str) -> bool:
"""验证证书"""
try:
with open(cert_path, 'rb') as f:
cert_data = f.read()
# 使用 OpenSSL 验证
result = subprocess.run(
['openssl', 'x509', '-in', cert_path, '-noout'],
capture_output=True
)
return result.returncode == 0
except Exception:
return False
def _update_ca_bundle(self):
"""更新 CA 包"""
cert_paths = ':'.join(self.certificates)
os.environ['NODE_EXTRA_CA_CERTS'] = cert_paths
### 证书格式转换
# 将 DER 格式转换为 PEM 格式
openssl x509 -inform der -in certificate.cer -out certificate.pem
# 将 PKCS#12 格式转换为 PEM 格式
openssl pkcs12 -in certificate.p12 -out certificate.pem -nodes
# 提取证书链
openssl s_client -connect server:port -showcerts
## 32.1.3 mTLS 身份验证
### mTLS 配置對於需要客戶端證書身份驗證的企業環境：
python
bash
bash
# 客户端证书
export CLAUDE_CODE_CLIENT_CERT=/path/to/client-cert.pem
# 客户端私钥
export CLAUDE_CODE_CLIENT_KEY=/path/to/client-key.pem
# 私钥密码短语（如果加密）
export CLAUDE_CODE_CLIENT_KEY_PASSPHRASE="your-passphrase"
### mTLS 配置管理器
class MTLSConfigManager:
"""mTLS 配置管理器"""
def __init__(self):
self.config = {
'client_cert': None,
'client_key': None,
'key_passphrase': None
}
def configure(self, mtls_settings: Dict) -> ConfigResult:
"""配置 mTLS"""
result = ConfigResult()
# 设置客户端证书
if 'client_cert' in mtls_settings:
cert_path = mtls_settings['client_cert']

self.config['client_cert'] = cert_path
os.environ['CLAUDE_CODE_CLIENT_CERT'] = cert_path
result.add_setting('CLAUDE_CODE_CLIENT_CERT', cert_path)
else:
result.add_error("Invalid client certificate")
# 设置客户端密钥
if 'client_key' in mtls_settings:
key_path = mtls_settings['client_key']
if self._validate_key(key_path):
self.config['client_key'] = key_path
