本文实例为大家分享了php微信百度天气预报的开发代码,供大家参考,具体内容如下

1.登录百度ak申请:http://lbsyun.baidu.com/apiconsole/key

php微信开发之百度天气预报

2.实现天气信息功能

baiduWeather.php 

<"" || (strstr($cityName,"+"))){ 
   return "发送城市加天气,例如北京天气"; 
  } 
  //获取到的ak 
  $ak = your ak; 
  //获取到的sk 
  $sk = your sk; 
  //调用接口 
  $url = 'http://api.map.baidu.com/telematics/v3/weather"error"]!=0){ 
   return $result["status"]; 
  } 
 
  $curHour = (int)date('H',time()); 
  $weather = $result["results"][0]; 
  $weatherArray[]=array("Title"=>$weather['currentCity']."天气预报","Description"=>"","PicUrl"=>"","Url"=>""); 
  for($i = 0;$i<count($weather["weather_data"]);$i++){ 
   $weatherArray[] = array("Title"=> 
    $weather["weather_data"][$i]["data"]."\n". 
    $weather["weather_data"][$i]["weather"]. 
    $weather["weather_data"][$i]["wind"]. 
    $weather["weather_data"][$i]["temperature"], 
    "Description"=>"", 
    "PicUrl"=>(($curHour>=6)&&($curHour< 
    18))"weather_data"][$i]["dayPictureUrl"]:$weather["weather_data"][$i]["nightPictureUrl"],"URL"=>"" 
   ); 
  } 
  return $weatherArray; 
 } 

3.实现天气消息事件

<"TOKEN", "weixin"); 
/** 
 * 百度天气预报案例实现 
 * 实现思路: 
 * 1.申请百度ak、sk 
 * 2.使用百度天气预报接口 
 * 3.实现天气信息功能 
 * 4.实现事件响应功能
