linux shell实现自动获取某地的天气和空气质量

因为工作需要，实现了一个自动获取某地天气和空气质量的shell程序。

#!/bin/bash

#时间：2015-6-21

#This module using to get the weather of Henan, from webpage:http://www.weather.com.cn/html/province/henan.shtml

echo "Program starting..."

#############################################################

#以下是变量定义，定义省（拼音和中文），市（拼音和中文）

province='河南'

province_PY='henan'

city='郑州'

city_PY='zhengzhou'

#############################################################

#以下是传出的变量，可以直接使用

#weather_state

#天气质量

#temperature1

#最高天气温度

#temperature2

#最低天气温度

#city_air

#天气质量

#city_pm25

#pm2.5指数

#city_aqi

#aqi指数

#Module 1, Wget the webpage from internet and saved as weather in current directory.

echo "Getting the weather from webpage..."

#The url where get the weather page. This page is from China Meteorologic Administration, Henan.

url="http://www.weather.com.cn/html/province/"$province_PY".shtml"

#date_doay is today's date, such as 2015-06-27

date_today=$(date +'%Y-%m-%d')

logFile=$date_today.log

wget -O - $url > weather_province

echo "Got the weather file from internet."

#Module 2, Analysize the weather file and getting the information

echo "Getting the weather information..."

#Geting the line where include the weather

sed -n '/'${city}'天气预报/p' weather_province > province.weather

echo " Province weather file created."

#As all the information at one line, replace <dl> as \n, making a city at a line

sed -n '/<dl>/p' province.weather | sed 's/<dl>/\n/g' > city.weather

echo " Citys weather file created."

#Geting the city weather as format lines

sed -n '/'${city}'/p' city.weather | sed 's/</\n</g' > one_city.weather

echo " city Weather file created."

#Analysize from the file to get the state information and temputer

echo "     Anaysizing the weather state"

weather_state=$(sed -n '/img alt/p' one_city.weather | awk -F '"' '{print $2}' | sed -n '1p')

echo "The weather state is " $weather_state

#Getting the tempture

sed -n '/℃/p' one_city.weather | awk -F '>' '{print $2}'

tempture1=$(sed -n '/℃/p' one_city.weather | awk -F '>' '{print $2}' | sed -n '1p')

tempture2=$(sed -n '/℃/p' one_city.weather | awk -F '>' '{print $2}' | sed -n '2p')

echo "The high tempture is " $tempture1

echo "The low tempture is " $tempture2

#以下的功能寻找天气质量

#Getting the weather quality from http://www.pm25.com//XX.html 
echo " Getting the file from http://www.pm25.com//xx.html" 
air_url="www.pm25.com/"$city_PY.html

wget -O - $air_url > city.air

city_air=$(sed -n '/全部监测点/p' city.air | awk -F '"' '{print $12}')

echo "The city air is " $city_air

city_pm25=$(sed -n '/全部监测点/p' city.air | awk -F '"' '{print $10}')

​
echo "The city pm 2.5 figure is: " $city_pm25

city_aqi=$(sed -n '/全部监测点/p' city.air | awk -F '"' '{print $8}')

echo "The city's air AQI index is:" $city_aqi

这里记录下，也让自己记住，在使用sed带参数的时候要用’${parameter_name}’才能被sed解析。

下面又对程序进行了改良，使用函数方式进行调用

#!/bin/bash

#时间：2015-6-21
#版本1.1，时间2015-7-6，更改脚本为函数调用式

#GetWeatherAir函数说明：
#功能，传入省市的信息，得到该城市的天气和空气参数
#1、参数说明
#   需要传递四个变量 省中文名称 省拼音 市中文名称 市拼音
#   调用示例 GetWeatherAir 河北 hebei 唐山 tangshan
#2、函数使用
#   默认函数中使用echo测试打印了取得的值（见注释部分2），实际使用中可以注释掉echo语句直接重定向输出使用
