1、一、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烫喇霰嘴(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
2、二、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.
3、三、微信公众平台，接口文件编写 jiekou.php<?php/* 无忧电脑技巧网 微信公众号功能源码 CopyRight 2015 All Rights Reserved*/define("TOKEN", "weixin2015");$wechatObj = new wechatCallbackapiTest();if (!isset($_GET['echostr'])) { $wechatObj->responseMsg();}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 = "<xml><ToUserName><![CDATA[%s]]></ToUserName><FromUserName><![CDATA[%s]]></FromUserName><CreateTime>%s</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[%s]]></Content></xml>"; $result = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content); return $result; } private function transmitNews($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']); } $newsTpl = "<xml><ToUserName><![CDATA[%s]]></ToUserName><FromUserName><![CDATA[%s]]></FromUserName><CreateTime>%s</CreateTime><MsgType><![CDATA[news]]></MsgType><Content><![CDATA[]]></Content><ArticleCount>%s</ArticleCount><Articles>$item_str</Articles></xml>"; $result = sprintf($newsTpl, $object->FromUserName, $object->ToUserName, time(), count($newsArray)); return $result; } private function logger($log_content) { }}?>
4、四、使用百度车联API 外狒芙梨V3.0接口,及访问应用AK码,编号微信天气接口源码:weatger.php<?phpfunction getWeatherInfo($city绿覆冗猩Name){ if ($cityName == "" || (strstr($cityName, "+"))){ return "发送天气+城市，例如'天气深圳'"; }//用户查询天气,回复关键词 规则 $url = "http://api.map.baidu.com/telematics/v3/weather?location=".urlencode($cityName)."&output=json&ak=自已申请的百度车联API AK代码";//构建通过百度车联API V3.0查询天气url链接 $ch = curl_init();//初始化会话curl_setopt($ch, CURLOPT_URL, $url);//设置会话参数curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//设置会话参数$output = curl_exec($ch);//执行curl会话 curl_close($ch);//关闭curl会话 $result = json_decode($output, true);//函数json_decode() 的功能时将json数据格式转换为数组。 if ($result["error"] != 0){ return $result["status"]; } $curHour = (int)date('H',time()); $weather = $result["results"][0];//按照微信公众号开发文档,组建设多图文回复信息 $weatherArray[] = array("Title" => $weather['currentCity']."当前天气:"."温度:".$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; $i < count($weather["weather_data"]); $i++) { $weatherArray[] = array("Title"=> $weather["weather_data"][$i]["date"]."\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;}?>
