获取天气信息的脚本

来源：互联网发布：手机端编程软件编辑：程序博客网时间：2024/04/30 03:47

代码是使用python3写的
核心部分是拼凑URL和HEADERS，这个URL是我个人对中国天气网的观察总结出来的！！！
预报信息都可以从中国天气网中抓取出来，下面的是针对实时预报的信息

#!/usr/bin/python3import requestsimport reimport times = str(time.time())s = re.sub(r'\.', '', s)if (len(s)==12):    s = s + '0'elif (len(s) == 11) :    s = s + '00'elif (len(s) == 10):    s = s + '000'url = 'http://d1.weather.com.cn/sk_2d/101010100.html?_=' + sheaders_str = '''Host: d1.weather.com.cnUser-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3Accept-Encoding: gzip, deflateUpgrade-Insecure-Requests: 1Cache-Control: max-age=0Referer: http://d1.weather.com.cn/sk_2d/101010100.html?_=1485338200590676Cookie: vjuids=-2a0fa51f.15929686632.0.1f0ebc7551e7e; vjlast=1482458425.1485337372.23; Hm_lvt_080dabacb001ad3dc8b9b9049b36d43b=1485337372; f_city=%E5%8C%97%E4%BA%AC%7C101010100%7C; Hm_lpvt_080dabacb001ad3dc8b9b9049b36d43b=1485337417; BIGipServerd1src_pool=1874396221.20480.0000Connection: keep-alive'''headers_list = re.findall(r'(.*?):(.*)', headers_str)headers = {}for item in headers_list:    headers[item[0]] = item[1].strip()html_text = ''times = 20while (times != 0):    try:        html = requests.get(url, headers = headers)        # set html encoding        html.encoding = 'utf-8'        if html.encoding == 'ISO-8859-1':            encodings = requests.utils.get_encodings_from_content(html.content)            if encodings:                html.encoding = encodings[0]            else:                html.encoding = html.apparent_encoding        # get html text or content        html_text = html.text        break    except requests.ConnectionError as e:        time.sleep(0.05)        times -= 1# html may be is nullif (len(html_text) > 0):    html_text = re.search(r'=.*?{(.*)}', html_text).group(1)    real_time_weather_list = re.findall('\"(.*?)\":\"(.*?)\"', html_text)    real_time_weather_map = {}    for item in real_time_weather_list:        real_time_weather_map[item[0]] = item[1]    print('place: %s' % real_time_weather_map['cityname'])    print('time: %s' % real_time_weather_map['time'])    print('temp: %s oC' % real_time_weather_map['temp'])    print('SD: %s'  %  real_time_weather_map['SD'])    print('WD: %s' % real_time_weather_map['WD'])    print('WS: %s' % real_time_weather_map['WS'])    print('AQI: %s' % real_time_weather_map['aqi'])    print('limitnumber: %s' % real_time_weather_map['limitnumber'])

获取省级代码：http://www.weather.com.cn/data/list3/city.xml?level=1
获取城市代码(比如安徽是22)：http://www.weather.com.cn/data/list3/city22.xml?level=2
获取区域代码（比如安庆是2206）：http://www.weather.com.cn/data/list3/city2206.xml?level=3
获取到安徽省安庆市望江县的代码是220607
然后去加上中国代码请求URL：http://m.weather.com.cn/data/101220607.html
就可以获取当地天气。

另外再给几个有用的探索得到的URL：
天气 FLASH实况：http://flash.weather.com.cn/sk2/101220607.xml
实况FLASH：http://flash.weather.com.cn/sk2/shikuang.swf?id=101220607
