In this tutorial, we will introduce how to develop the weather forecast function on the WeChat public platform. We will use the meteorological data interface of China Weather Network to obtain weather information.

This tutorial will cover the following:

1. China Weather Network

China Weather Network provides a rich meteorological data interface. Below we introduce the main ones:

National root node interface:

http://flash.weather.com.cn/wmaps/xml/china.xml

<span <</span><span city </span><span quName</span><span ="广东"</span><span  pyName</span><span ="guangdong"</span><span  cityname</span><span ="广州"</span><span  state1</span><span ="2"</span><span  state2</span><span ="7"</span><span  stateDetailed</span><span ="阴转小雨"</span><span  tem1</span><span ="8"</span><span  tem2</span><span ="15"</span><span  windState</span><span ="微风"</span><span /></span>

Provincial node interface (taking Guangdong as an example):

http://flash.weather.com.cn/wmaps/xml/Guangdong.xml

<span <</span><span city </span><span cityX</span><span ="409"</span><span  cityY</span><span ="257"</span><span  cityname</span><span ="深圳"</span><span  centername</span><span ="深圳"</span><span  fontColor</span><span ="FFFFFF"</span><span  pyName</span><span ="shenzhen"</span><span  state1</span><span ="1"</span><span  state2</span><span ="1"</span><span  stateDetailed</span><span ="多云"</span><span  tem1</span><span ="12"</span><span  tem2</span><span ="18"</span><span  temNow</span><span ="12"</span><span  windState</span><span ="微风"</span><span  windDir</span><span ="东北风"</span><span  windPower</span><span ="1级"</span><span  humidity</span><span ="74%"</span><span  time</span><span ="21:15"</span><span  url</span><span ="101280601"</span><span /></span>

.

Real-time weather data (taking Shenzhen as an example):

http://www.weather.com.cn/data/sk/101280601.html

<span {
    </span><span "</span><span weatherinfo</span><span "</span><span : {

The above interface is the interface we will use for the weather forecast function.

2. WeChat public platform development

1. The city code comparison table needs to be imported into the database. The following is a screenshot after SAE import

2. Method to convert city name to city code, which will be called when the user sends the city name

<span  1</span> <span function</span> fromNameToCode(<span $name</span><span )
</span><span  2</span> <span {
</span><span  3</span>     <span $mysql_host</span> =<span  SAE_MYSQL_HOST_M;
</span><span  4</span>     <span $mysql_host_s</span> =<span  SAE_MYSQL_HOST_S;
</span><span  5</span>     <span $mysql_port</span> =<span  SAE_MYSQL_PORT;
</span><span  6</span>     <span $mysql_user</span> =<span  SAE_MYSQL_USER;
</span><span  7</span>     <span $mysql_password</span> =<span  SAE_MYSQL_PASS;
</span><span  8</span>     <span $mysql_database</span> =<span  SAE_MYSQL_DB;
</span><span  9</span> 
<span 10</span>     <span $mysql_table</span> = "weather"<span ;
</span><span 11</span>     <span $mysql_state</span> = "SELECT * FROM ".<span $mysql_table</span>." WHERE `cityName` = '".<span $name</span>."'"<span ;
</span><span 12</span>     
<span 13</span>     <span $con</span> = <span mysql_connect</span>(<span $mysql_host</span>.':'.<span $mysql_port</span>, <span $mysql_user</span>, <span $mysql_password</span>, <span true</span><span );
</span><span 14</span>     <span if</span> (!<span $con</span><span ){
</span><span 15</span>         <span die</span>('Could not connect: ' . <span mysql_error</span><span ());
</span><span 16</span> <span     }
</span><span 17</span>     <span mysql_query</span>("SET NAMES 'UTF8'"<span );
</span><span 18</span>     <span mysql_select_db</span>(<span $mysql_database</span>, <span $con</span><span );
</span><span 19</span>     <span $result</span> = <span mysql_query</span>(<span $mysql_state</span><span );
</span><span 20</span>     <span $cityCode</span> = ""<span ;
</span><span 21</span>     <span while</span>(<span $row</span> = <span mysql_fetch_array</span>(<span $result</span><span ))
</span><span 22</span> <span     {
</span><span 23</span>         <span $cityCode</span> = <span $row</span>['cityCode'<span ]; 
</span><span 24</span>         <span break</span><span ;
</span><span 25</span> <span     }
</span><span 26</span>     <span mysql_close</span>(<span $con</span><span );
</span><span 27</span>     <span return</span> <span $cityCode</span><span ;
</span><span 28</span> }

3. Write an interface call function to send a cURL request to the weather network and obtain data

<span  1</span> <span function</span> httpRequest(<span $url</span><span )
</span><span  2</span> <span {
</span><span  3</span>     <span $ch</span> =<span  curl_init();
</span><span  4</span>     curl_setopt(<span $ch</span>, CURLOPT_URL, <span $url</span><span );
</span><span  5</span>     curl_setopt(<span $ch</span>, CURLOPT_RETURNTRANSFER, 1<span );
</span><span  6</span>     <span $output</span> = curl_exec(<span $ch</span><span );
</span><span  7</span>     curl_close(<span $ch</span><span );
</span><span  8</span>     <span if</span> (<span $output</span> === <span FALSE</span><span ){
</span><span  9</span>         <span return</span> "cURL Error: ". curl_error(<span $ch</span><span );
</span><span 10</span> <span     }
</span><span 11</span>     <span return</span> <span $output</span><span ;
</span><span 12</span> }

4. Write a function to obtain weather data. Here, real-time weather and weather for the next 3 days are obtained, and the returned results are encapsulated into an array of graphic and text information

<span  1</span> <span function</span> getWeatherInfo(<span $cityName</span><span )
</span><span  2</span> <span {
</span><span  3</span>     <span $cityCode</span> = fromNameToCode(<span $cityName</span><span );
</span><span  4</span>     
<span  5</span>     <span if</span> (<span $cityCode</span> == ""<span )
</span><span  6</span> <span     {
</span><span  7</span>         <span return</span> "错误的城市名或者此城市不在数据库中!"<span ;
</span><span  8</span> <span     }
</span><span  9</span>     
<span 10</span>     <span //</span><span 获取实时天气</span>
<span 11</span>     <span $url</span> = "http://www.weather.com.cn/data/sk/".<span $cityCode</span>.".html"<span ;
</span><span 12</span>     <span $output</span> = httpRequest(<span $url</span><span );
</span><span 13</span>     <span $weather</span> = json_decode(<span $output</span>, <span true</span><span ); 
</span><span 14</span>     <span $info</span> = <span $weather</span>['weatherinfo'<span ];
</span><span 15</span> 
<span 16</span>     <span $weatherArray</span> = <span array</span><span ();
</span><span 17</span>     <span $weatherArray</span>[] = <span array</span>("Title"=>$info['city']."天气预报", "Description"=>"", "PicUrl"=>"", "Url" =>""<span );
</span><span 18</span>     <span if</span> ((int)<span $cityCode</span> < 101340000<span ){
</span><span 19</span>         <span $result</span> = "实况 温度:".<span $info</span>['temp']."℃ 湿度:".<span $info</span>['SD']." 风速:".<span $info</span>['WD'].<span $info</span>['WSE']."级"<span ;
</span><span 20</span>         <span $weatherArray</span>[] = <span array</span>("Title"=><span str_replace</span>("%", "﹪", <span $result</span>), "Description"=>"", "PicUrl"=>"", "Url" =>""<span );
</span><span 21</span> <span     }
</span><span 22</span> 
<span 23</span>     <span //</span><span 获取六日天气</span>
<span 24</span>     <span $url</span> = "http://m.weather.com.cn/data/".<span $cityCode</span>.".html"<span ;
</span><span 25</span>     <span $output</span> = httpRequest(<span $url</span><span );
</span><span 26</span>     <span $weather</span> = json_decode(<span $output</span>, <span true</span><span ); 
</span><span 27</span>     <span $info</span> = <span $weather</span>['weatherinfo'<span ];
</span><span 28</span> 
<span 29</span>     <span if</span> (!<span empty</span>(<span $info</span>['index_d'<span ])){
</span><span 30</span>         <span $weatherArray</span>[] = <span array</span>("Title" =><span $info</span>['index_d'], "Description" =>"", "PicUrl" =>"", "Url" =>""<span );
</span><span 31</span> <span     }
</span><span 32</span> 
<span 33</span>     <span $weekArray</span> = <span array</span>("日","一","二","三","四","五","六"<span );
</span><span 34</span>     <span $maxlength</span> = 3<span ;
</span><span 35</span>     <span for</span> (<span $i</span> = 1; <span $i</span> <= <span $maxlength</span>; <span $i</span>++<span ) {
</span><span 36</span>         <span $offset</span> = <span strtotime</span>("+".(<span $i</span>-1)." day"<span );
</span><span 37</span>         <span $subTitle</span> = <span date</span>("m月d日",<span $offset</span>)." 周".<span $weekArray</span>[<span date</span>('w',<span $offset</span>)]." ".<span $info</span>['temp'.<span $i</span>]." ".<span $info</span>['weather'.<span $i</span>]." ".<span $info</span>['wind'.<span $i</span><span ];
</span><span 38</span>         <span $weatherArray</span>[] = <span array</span>("Title" =><span $subTitle</span>, "Description" =>"", "PicUrl" =>"http://discuz.comli.com/weixin/weather/"."d".<span sprintf</span>("%02u",<span $info</span>['img'.((<span $i</span> *2)-1)]).".jpg", "Url" =>""<span );
</span><span 39</span> <span     }
</span><span 40</span> 
<span 41</span>     <span return</span> <span $weatherArray</span><span ;
</span><span 42</span> }
