$ak,
'location' => $location,
'output' => $output
);
$querystring = http_build_query($querystring_arrays);
//生成sn
$sn = md5(urlencode($uri.'?'.$querystring.$sk));
$targetUrl = sprintf($url,$ak,urlencode($location),$output,$sn);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$targetUrl);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result,true);
if($result["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
$weather["weather_data"][$i]["data"]."\n".
$weather["weather_data"][$i]["weather"].
$weather["weather_data"][$i]["wind"].
$weather["weather_data"][$i]["temperature"],
"Description"=>"",
"PicUrl"=>(($curHour>=6)&&($curHour<
18))?$weather["weather_data"][$i]["dayPictureUrl"]:$weather["weather_data"][$i]["nightPictureUrl"],"URL"=>""
);
}
return $weatherArray;
} 3.实现天气消息事件

}
