entry: // 成功发送到通道 default: // 通道满丢弃日志避免阻塞 logger.Warn(日志队列已满丢弃日志条目) } } }4.2 采样与降级策略对于高流量应用实现日志采样func SampledLogger(sampleRate float64) martini.Handler { return func(c martini.Context, req *http.Request) { if rand.Float64() sampleRate { c.Next() return } // 只记录部分请求的详细日志 start : time.Now() c.Next() log.Printf([SAMPLED] %s %s - %dms, req.Method, req.URL.Path, time.Since(start).Milliseconds()) } }第五步安全与合规性5.1 敏感信息过滤func SanitizedLogger() martini.Handler { sensitiveFields : []string{password, token, secret, credit_card} return func(c martini.Context, req *http.Request) { // 复制请求参数并过滤敏感信息 sanitizedParams : make(map[string]interface{}) for k, v : range req.URL.Query() { if contains(sensitiveFields, k) { sanitizedParams[k] [REDACTED] } else { sanitizedParams[k] v } } log.Printf(请求参数: %v, sanitizedParams) c.Next() } }5.2 GDPR合规日志func GDPRCompliantLogger() martini.Handler { return func(c martini.Context, req *http.Request) { // 记录数据主体相关信息 logData : map[string]interface{}{ timestamp: time.Now().UTC().Format(time.RFC3339), purpose: 系统监控与故障排查, retention_period: 30天, data_controller: 您的公司名称, } // 确保不记录个人身份信息 if ip : req.RemoteAddr; ip ! { // 对IP地址进行匿名化处理 anonymizedIP : anonymizeIP(ip) logData[anonymized_ip] anonymizedIP } logJSON(logData) c.Next() } }实战部署指南6.1 Docker容器日志配置# Dockerfile配置 FROM golang:1.19-alpine # 设置日志环境变量 ENV LOG_LEVELinfo ENV LOG_FORMATjson ENV LOG_OUTPUTstdout # 构建应用 COPY . .
