日志分析实战之清洗日志小实例5：实现获取不能访问url

思路： 1.获取request字段 2.过滤不需要字符 3.实现获取url，并打印输出 1.创建getRequest函数获取request字段 [Scala] 纯文本查看复制代码 ?...// get the `request` field from an access log record def getRequest(rawAccessLogString: String): Option...：上面看似简单，其实有很多需要说明的 val recs = log.filter(line => getStatusCode(p.parseRecord(line)) == "404").map(getRequest...(_)) 上面得出404对应的url.getRequest是上面我们定义的函数 val distinctRecs = log.filter(line => getStatusCode(p.parseRecord...(line)) == "404").map(getRequest(_)).distinct 这里多了distinct是为了去重，下面是直接打印。
