天气预报接口

学习永不止步，誓雪与您共勉

    也许在我们开发的东东里会涉及到一些小的信息，比如像天气这样的信息的获取，国家气象局提供了三种数据的形式。

那下面拿北京为例，要想得到有关北京的天气信息，可以去请求下面的三种接口。

接口为：

http://www.weather.com.cn/data/sk/101010100.html

http://www.weather.com.cn/data/cityinfo/101010100.html

http://m.weather.com.cn/data/101010100.html

对于以上的三种接口信息，大家可以访问一下试试，要想得到更详细的信息，可以运用第三种方式。

第一种json串的key-value为：

{"weatherinfo":{"city":"北京","cityid":"101010100","temp":"-1","WD":"西南风","WS":"2级","SD":"43%","WSE":"2","time":"18:30","isRadar":"1","Radar":"JC_RADAR_AZ9010_JB"}}

 

第二种json串的key-value为：

{"weatherinfo":{"city":"北京","cityid":"101010100","temp1":"-8℃","temp2":"3℃","weather":"晴","img1":"n0.gif","img2":"d0.gif","ptime":"18:00"}}

 

第三种json串的key-value为：

{"weatherinfo":{"city":"北京","city_en":"beijing","date_y":"2013年1月17日","date":"","week":"星期四","fchh":"18","cityid":"101010100","temp1":"-8℃~3℃","temp2":"-6℃~2℃","temp3":"-3℃~-1℃","temp4":"-5℃~4℃","temp5":"-8℃~2℃","temp6":"-7℃~4℃","tempF1":"17.6℉~37.4℉","tempF2":"21.2℉~35.6℉","tempF3":"26.6℉~30.2℉","tempF4":"23℉~39.2℉","tempF5":"17.6℉~35.6℉","tempF6":"19.4℉~39.2℉","weather1":"晴","weather2":"晴转阴","weather3":"小雪","weather4":"多云","weather5":"晴","weather6":"多云","img1":"0","img2":"99","img3":"0","img4":"2","img5":"14","img6":"99","img7":"1","img8":"99","img9":"0","img10":"99","img11":"1","img12":"99","img_single":"0","img_title1":"晴","img_title2":"晴","img_title3":"晴","img_title4":"阴","img_title5":"小雪","img_title6":"小雪","img_title7":"多云","img_title8":"多云","img_title9":"晴","img_title10":"晴","img_title11":"多云","img_title12":"多云","img_title_single":"晴","wind1":"微风","wind2":"微风","wind3":"微风","wind4":"微风转北风3-4级","wind5":"北风3-4级转微风","wind6":"微风","fx1":"微风","fx2":"微风","fl1":"小于3级","fl2":"小于3级","fl3":"小于3级","fl4":"小于3级转3-4级","fl5":"3-4级转小于3级","fl6":"小于3级","index":"冷","index_d":"天气冷，建议着棉衣、皮夹克加羊毛衫等冬季服装。年老体弱者宜着厚棉衣或冬大衣。","index48":"冷","index48_d":"天气冷，建议着棉衣、皮夹克加羊毛衫等冬季服装。年老体弱者宜着厚棉衣或冬大衣。","index_uv":"弱","index48_uv":"最弱","index_xc":"较适宜","index_tr":"较适宜","index_co":"较不舒适","st1":"2","st2":"-6","st3":"3","st4":"-4","st5":"0","st6":"-4","index_cl":"适宜","index_ls":"基本适宜","index_ag":"极不易发"}}

对于第三种json的key-value信息的意思为：

城市名，英文名，日期，农历日期，星期，预报时间，城市代码，6个预报温度（华氏温度，摄氏温度），6个预报天气和风力，其余的就是一些气象指数，一些供大家参考的穿衣信息等。

 

需要补充的是对于城市的代号为：

若想获取其他城市的天气信息，将url后面的数值换成对应的城市的代码即可。

至于怎样去请求以上的天气接口，我想大家应该会吧！要是不会的话建议大家参考一下下面的链接地址，仅供参考：http://blog.sina.com.cn/s/blog_6ce9e8870101bu1j.html

下面拿北京为例子进行解析接口返回json串信息。

$requesturl="http://www.weather.com.cn/data/sk/101010100.html";

$ch = curl_init();

// 设置URL和相应的选项

curl_setopt($ch, CURLOPT_URL, $requesturl);

curl_setopt($ch, CURLOPT_HEADER, 0);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$info=curl_exec($ch);

// 关闭cURL资源，并且释放系统资源

curl_close($ch);

//对返回的json串进行decode,分解后与下面的数组一起合成json串

$info=json_decode($info,true);

echo mb_convert_encoding($info['weatherinfo']['city'],'gb2312','UTF-8'); 访问其他信息就很简单了。
