API Strategy (接口策略)

认证方式说明

API	认证方式	免费额度	配置要求
wttr.in	无需认证	无限制	❌ 无需任何配置
和风天气	API Host + Key	1000次/天	✅ 需要API_HOST + API_KEY
OpenWeatherMap	API Key	1000次/天	✅ 需要API_KEY + 绑定信用卡
心知天气	API Key	无限制	✅ 需要API_KEY

推荐：优先使用wttr.in（无需任何配置，免费无限制）

降级策略

# 优先级：无需配置 → 需要配置
API_CHAIN = [
    {"name": "wttr", "requires_key": False},      # 无需任何配置
    {"name": "qweather", "requires_key": True},    # 需要API Host + Key
    {"name": "openweathermap", "requires_key": True} # 需要Key + 信用卡
]

和风天气配置说明（重要）

和风天气从2026年起不再支持公共API地址，必须使用专属API Host：

# 环境变量配置
export QWEATHER_API_HOST="你的API_HOST"  # 如：abc1234xyz.def.qweatherapi.com
export QWEATHER_API_KEY="你的API_KEY"

# 正确的API调用
curl "https://${QWEATHER_API_HOST}/v7/weather/now?location=101010100&key=${QWEATHER_API_KEY}"

注意：响应使用gzip压缩，需要添加--compressed参数或在代码中处理

降级策略

API_CHAIN = [
    {"name": "qweather", "priority": 1, "fallback": True},
    {"name": "seniverse", "priority": 2, "fallback": True},
    {"name": "openweathermap", "priority": 3, "fallback": True},
    {"name": "wttr", "priority": 4, "fallback": False}
]

def get_weather_with_fallback(city):
    """Try APIs in priority order, fallback on failure"""
    for api in API_CHAIN:
        try:
            result = call_api(api["name"], city)
            if result:
                return result
        except Exception as e:
            if api["fallback"]:
                continue
            else:
