This article mainly introduces the relevant information of Baidu weather forecast developed by PHP WeChat in detail. It has certain reference value. Interested friends can refer to it
1. Log in Baidu ak application:http://lbsyun.baidu.com/apiconsole/key
2. Implement weather information function
baiduWeather.php
$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. Implement weather message events
responseMsg(); }else{ $wechatObj->valid(); } class wechatCallbackapiTest { //验证签名 public function valid() { $echoStr = $_GET["echostr"]; if($this->checkSignature()){ header('content-type:text'); echo $echoStr; exit; } } public function checkSignature(){ $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); sort($tmpArr); $tmpStr = implode($tmpArr); $tmpStr = sha1($tmpStr); if($tmpStr == $signature) { return true; }else{ return false; } } //响应消息 public function responseMsg() { $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; if (!empty($postStr)){ $this->logger("R ".$postStr); $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $RX_TYPE = trim($postObj->MsgType); //消息类型分离 switch ($RX_TYPE) { case "event": $result = $this->receiveEvent($postObj); break; case "text": $result = $this->receiveText($postObj); break; default: $result = "unknown msg type: ".$RX_TYPE; break; } echo $result; }else { echo ""; exit; } } //接收事件消息 public function receiveEvent($object) { $content = ""; switch ($object->Event) { case "subscribe": $content = "欢迎关注Nicky的公众号 "; $content .= (!empty($object->EventKey))?("\n来自二维码场景 ".str_replace("qrscene_","",$object->EventKey)):""; break; case "unsubscribe": $content = "取消关注"; break; } $result = $this->transmitText($object, $content); return $result; } //接收文本消息 public function receiveText($object) { $keyword = trim($object->Content); //自动回复模式 if (strstr($keyword, "天气")){ $city = str_replace('天气','',$keyword); include("baiduweather.php"); $content = getWeatherInfo($city); } $result = $this->transmitNews($object, $content); return $result; } //回复图文消息 public function transmitNews($object, $newsArray) { if(!is_array($newsArray)){ return; } $itemTpl = "- "; $item_str = ""; foreach ($newsArray as $item){ $item_str .= sprintf($itemTpl, $item['Title'], $item['Description'], $item['PicUrl'], $item['Url']); } $xmlTpl = "
"; $result = sprintf($xmlTpl, $object->FromUserName, $object->ToUserName, time(), count($newsArray)); return $result; } //日志记录 public function logger($log_content) { if(isset($_SERVER['HTTP_APPNAME'])){ //SAE sae_set_display_errors(false); sae_debug($log_content); sae_set_display_errors(true); }else if($_SERVER['REMOTE_ADDR'] != "127.0.0.1"){ //LOCAL $max_size = 10000; $log_filename = "log.xml"; if(file_exists($log_filename) and (abs(filesize($log_filename)) > $max_size)){unlink($log_filename);} file_put_contents($log_filename, date('H:i:s')." ".$log_content."\r\n", FILE_APPEND); } } } ?> %s %s $item_str
