定时拨测指定url连通性

定时检测服务器到外网域名的连通性，这里脚本分享给大家，需要的自取

#!/bin/bash

# 定义要测试的 URL 列表
urls=("https://www.baidu.com" "https://www.google.com")

# 获取当前时间
current_time=$(date "+%Y-%m-%d %H:%M:%S")

# 定义日志文件夹路径
log_dir="/data/boce/logs"
# 如果日志文件夹不存在，则创建该文件夹
mkdir -p "$log_dir"

# 定义日志文件路径
log_file="$log_dir/url_check_$(date '+%Y-%m-%d').log"

# 循环测试每个 URL
for url in "${urls[@]}"; do
  # 使用 curl 测试 URL 并获取详细错误信息，同时获取 HTTP 状态码
  response=$(curl -s --head --request GET "$url" --connect-timeout 10 --max-time 15)
  http_code=$(echo "$response" | head -n 1 | awk '{print $2}')
  
  # 检查 curl 执行是否成功
  if [ $? -eq 0 ]; then
    # 如果连接成功，记录日志，包括状态码
    if [[ "$http_code" =~ ^2[0-9]{2}$ || "$http_code" =~ ^3[0-9]{2}$ ]]; then
      echo "$current_time - $url is reachable. HTTP Status: $http_code" >> "$log_file"
    else
      echo "$current_time - $url is unreachable. HTTP Status: $http_code" >> "$log_file"
    fi
  else
    # 如果 curl 执行失败，捕获并记录错误信息
    error_message=$(curl -s --head --request GET "$url" --connect-timeout 10 --max-time 15 2>&1)
    
    # 判断错误信息并记录具体的错误原因
    if [[ "$error_message" == *"Connection timed out"* ]]; then
