根据以下使用文档提示，解释下安装和配置方法1. Installation
First, ensure you have Claude Code installed:
npm install -g @anthropic-ai/claude-code
Then, install Claude Code Router:
npm install -g @musistudio/claude-code-router
2. Configuration
Create and configure your ~/.claude-code-router/config.json file. For more details, you can refer to config.example.json.
The config.json file has several key sections:
PROXY_URL (optional): You can set a proxy for API requests, for example: "PROXY_URL": "http://127.0.0.1:7890".
LOG (optional): You can enable logging by setting it to true. When set to false, no log files will be created. Default is true.
LOG_LEVEL (optional): Set the logging level. Available options are: "fatal", "error", "warn", "info", "debug", "trace". Default is "debug".
Logging Systems: The Claude Code Router uses two separate logging systems:
Server-level logs: HTTP requests, API calls, and server events are logged using pino in the ~/.claude-code-router/logs/ directory with filenames like ccr-*.log
Application-level logs: Routing decisions and business logic events are logged in ~/.claude-code-router/claude-code-router.log
APIKEY (optional): You can set a secret key to authenticate requests. When set, clients must provide this key in the Authorization header (e.g., Bearer your-secret-key) or the x-api-key header. Example: "APIKEY": "your-secret-key".
HOST (optional): You can set the host address for the server. If APIKEY is not set, the host will be forced to 127.0.0.1 for security reasons to prevent unauthorized access. Example: "HOST": "0.0.0.0".
NON_INTERACTIVE_MODE (optional): When set to true, enables compatibility with non-interactive environments like GitHub Actions, Docker containers, or other CI/CD systems. This sets appropriate environment variables (CI=true, FORCE_COLOR=0, etc.) and configures stdin handling to prevent the process from hanging in automated environments. Example: "NON_INTERACTIVE_MODE": true.
Providers: Used to configure different model providers.
Router: Used to set up routing rules. default specifies the default model, which will be used for all requests if no other route is configured.
API_TIMEOUT_MS: Specifies the timeout for API calls in milliseconds.
Environment Variable Interpolation
Claude Code Router supports environment variable interpolation for secure API key management. You can reference environment variables in your config.json using either $VAR_NAME or ${VAR_NAME} syntax:
{
"OPENAI_API_KEY": "$OPENAI_API_KEY",
"GEMINI_API_KEY": "${GEMINI_API_KEY}",
"Providers": [
{
"name": "openai",
"api_base_url": "https://api.openai.com/v1/chat/completions",
"api_key": "$OPENAI_API_KEY",
"models": ["gpt-5", "gpt-5-mini"]
}
]
}
This allows you to keep sensitive API keys in environment variables instead of hardcoding them in configuration files. The interpolation works recursively through nested objects and arrays.
Here is a comprehensive example:

"PROXY_URL": "http://127.0.0.1:7890",

3. Running Claude Code with the Router
Start Claude Code using the router:
ccr code
Note: After modifying the configuration file, you need to restart the service for the changes to take effect:
ccr restart
