　　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：

　　2.实现天气信息功能

　　baiduWeather.php

　　 <?php /** * 使用百度天气预报接口获取城市天气信息案例实现 */ //获取城市天气信息 function getWeatherInfo($cityName){ if($cityName == (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 = 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<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))?$weather[weather_data][$i][dayPictureUrl]:$weather[weather_data][$i][nightPictureUrl],URL=> ); } return $weatherArray; }

　　3.实现天气消息事件

　　 <?php /* CopyRight 2016 All Rights Reserved */ define(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 */ $wechatObj = new wechatCallbackapiTest(); if (!isset($_GET[echostr])) { $wechatObj->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> <Title><![CDATA[%s]]></Title> <Description><![CDATA[%s]]></Description> <PicUrl><![CDATA[%s]]></PicUrl> <Url><![CDATA[%s]]></Url> </item> ; $item_str = ; foreach ($newsArray as $item){ $item_str .= sprintf($itemTpl, $item[Title], $item[Description], $item[PicUrl], $item[Url]); } $xmlTpl = <xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[news]]></MsgType> <ArticleCount>%s</ArticleCount> <Articles> $item_str</Articles> </xml>; $result = sprintf($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); } } } ?>
