微信公众平台开发之天气预报功能，公众平台天气预报

微信公众平台开发之天气预报功能，公众平台天气预报最近有项目需求给微信公众号上增加了天气预报功能,使用百度提供的车联网API V3.0中的天气查询功能实现.先上一张最终效果图:项目需求：有连接好的微信平台,有百度注册帐号,需要在百度LBS开放云平台,添加应用,获取AK代码，PHP代码编辑器,如EditPlus等下面详细介绍下开发步骤：第一步：准备工作 登录微信公众平台,检查服务器配置是否已启用,URL(服务器地址) 是否已配置Token(令牌),与自己写的微信入口文件中的Token(令牌一致),如下图:然后点击提交,只至网页上提示绿色背景的提交成功信息,则完成本步骤的操作第二步：微信天气预报数据源准备 用已注册好的百度帐号,登录百度LBS云平台,添加一个应用,获取访问应用AK，及了解车联API V3.0,天气查询功能相应的接口说明文件,以按需调用需要的天气信息.第三步：微信公众平台，接口文件编写 jiekou.phpresponseMsg();}else{ $wechatObj->valid();}class wechatCallbackapiTest{ //验证签名 public function valid() { $echoStr = $_GET["echostr"]; $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){ echo $echoStr; exit; } } public function responseMsg() { // $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; $postStr = file_get_contents("php://input"); if (!empty($postStr)){ $this->logger("R ".$postStr); $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $RX_TYPE = trim($postObj->MsgType); $result = ""; switch ($RX_TYPE) { case "event": $result = $this->receiveEvent($postObj); break; case "text": $result = $this->receiveText($postObj); break; } $this->logger("T ".$result); echo $result; }else { echo ""; exit; } } private function receiveEvent($object) { switch ($object->Event) { case "subscribe": $content = "欢迎关注无忧电脑技巧网 "; break; } $result = $this->transmitText($object, $content); return $result; } private function receiveText($object) { $keyword = trim($object->Content); //获得用户输入的信息 //判断天气 if(!empty( $keyword )){ //!empty 函数,判断 $keyword获得的值是否为空 $city = mb_substr($keyword, 0, 2, 'utf-8'); //取用户输入内容前两个字符,如"黄冈天气" 最终取值"黄冈" include("weather.php"); //调用天气接口文件 $content = getWeatherInfo($city); //执行天气接口文件中的 getWeatherInfo方法.查询 黄冈天气. } else{ $content = date("Y-m-d H:i:s",time())."\n技术支持 无忧电脑技巧网\nwww.51pcjq.com"; //发送其它内容默认回复的内容. } if(is_array($content)){ if (isset($content[0]['PicUrl'])){ $result = $this->transmitNews($object, $content); }else if (isset($content['MusicUrl'])){ $result = $this->transmitMusic($object, $content); } }else{ $result = $this->transmitText($object, $content); } return $result; } private function transmitText($object, $content) { if (!isset($content) || empty($content)){ return ""; } $textTpl = ""; $result = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content); return $result; } private function transmitNews($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']); } $newsTpl = ""; $result = sprintf($newsTpl, $object->FromUserName, $object->ToUserName, time(), count($newsArray)); return $result; } private function logger($log_content) { }}登录后复制第四步:使用百度车联API V3.0接口,及访问应用AK码,编号微信天气接口源码:weatger.php $weather['currentCity']."当前天气:"."温度:".$weather['weather_data'][0]['temperature'].",".$weather['weather_data'][0]['weather'].","."风力:".$weather['weather_data'][0]['wind'].".", "Description" =>"", "PicUrl" =>"http://weixin.51pcjq.com/img/weather_bg.jpg", "Url" =>""); for ($i = 0; $i $weather["weather_data"][$i]["date"]."\n". $weather["weather_data"][$i]["weather"]."
