Overview

Debug Provider is a virtual DNS provider specifically designed for debugging and testing purposes. It simulates the DNS record update process but does not perform any actual operations, only outputs relevant information to the console to help developers debug DDNS configuration and functionality.

Development Documentation: Provider Development Guide

Important Notice

Debug Provider is only for debugging and testing, it does not perform any actual DNS update operations
Only prints detected IP addresses and domain information to the console
Suitable for verifying configuration file format and IP address detection functionality

Authentication Information

Debug Provider does not require any authentication information, no need to configure id and token parameters.

jsonc

{
    "dns": "debug"  // Only need to specify provider as debug
}

Complete Configuration Example

jsonc

{
    "$schema": "https://ddns.newfuture.cc/schema/v4.1.json", // Format validation
    "dns": "debug",                     // Current provider
    "index4": ["url:http://api.ipify.cn", "public"], // IPv4 address source
    "index6": "public",                     // IPv6 address source
    "ipv4": ["ddns.newfuture.cc"],           // IPv4 domains
    "ipv6": ["ipv6.ddns.newfuture.cc"], // IPv6 domains
    "cache": false,                    // Recommend disabling cache for debugging
    "log": {
        "level": "debug"               // Log level
    }
}

Command Line Usage

ddns --debug

Specify Parameters

ddns --dns debug --index4=0 --ipv4=ddns.newfuture.cc --debug

Output Log

log

INFO  DebugProvider: ddns.newfuture.cc(A) => 192.168.1.100

Error Simulation

Debug Provider also simulates some common error scenarios to help test error handling logic.

Troubleshooting

Common Issues

No output information: Check log level settings, ensure DEBUG level is enabled
IP detection failed: Check network connection and IP source configuration
Configuration format error: Use JSON validation tools to check configuration file format
