SAE新近开放的实时日志API允许开发者通过HTTP GET方式从SAE服务器获取应用日志,从而实现在线的应用调试与分析。
SAE日志API的URL请求格式为:GET /log/(string: service)/(string: date)/(string: ident).log?(string: fop)
参数列表中:
date表示日志的日期,格式为yyyy-MM-dd
service为SAE提供的各项服务,包括http,taskqueue(任务队列),cron(定时任务),mail(邮件),rdc(关系型数据库集群),storage(存储),push(推送)以及fetchurl(URL抓取),相信熟悉SAE的开发者不会对此感到陌生。
ident表示相应服务下的日志类型,包括access(访问),error(错误),alert(警报),debug(调试),warning(警告)与 notice(通知)。
service与ident的对应关系见下表(摘自SAE日志API文档):
service ident http access、error、alert、debug、warning、notice taskqueue error cron error mail access、error rdc error、warning storage access push access fetchurl access
fop(似乎是flow operation的简称),为流式操作参数,支持head,tail,grep等linux下常用的shell命令;并且支持管道,操作之间用竖线分隔 ...
