本文主要為大家詳細介紹了PHP微信開發之簡單實現查詢城市天氣的相關資料,有興趣的小伙伴們可以參考一下。希望對大家有幫助。
PHP微信查詢城市天氣,首先,你需要找到一個獲取天氣的API,此處,我用的是百度的apistore,申請和使用API的網址:http://apistore.baidu.com /apiworks/servicedetail/112.html
登入百度帳號,並用手機傳送請求取得apikey。有了apikey,可以按照它的範例來請求城市天氣了。 (可以依照城市中文名,拼音,城市編號等來查詢)
#你可以現在本地做測試,請求完成之後,再放到自己的網域空間的腳本裡。
測試的腳本例如:(注意apikey填寫自己申請的)
header('Content-type:text/html;charset=UTF-8'); $ch = curl_init(); $url = 'http://apis.baidu.com/apistore/weatherservice/cityname?cityname=上海'; $header = array( 'apikey: ',//你的apikey ); // 添加apikey到header curl_setopt($ch, CURLOPT_HTTPHEADER , $header); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 执行HTTP请求 curl_setopt($ch , CURLOPT_URL , $url); $res = curl_exec($ch); $res = json_decode($res, true); echo "<pre class="brush:php;toolbar:false">"; print_r($res); echo ""; $contentStr = ""; foreach($res as $k=>$v){ if($k == "retData"){ $contentStr = "城市:" . $v['city'] . "\n"; $contentStr .= "日期:" . $v['date'] . "\n"; $contentStr .= "天气:" . $v['weather'] ."\n"; $contentStr .= "平均气温:" . $v['temp'] . "℃\n"; $contentStr .= "最低气温:" . $v['l_tmp'] ."℃\n"; $contentStr .= "最高气温:" . $v['h_tmp'] . "℃\n"; $contentStr .= "风力:" . $v['WS'] . "\n"; $contentStr .= "风向:" . $v['WD'] . "\n"; $contentStr .= "日出时间:" . $v['sunrise'] . "\n"; $contentStr .= "日落时间:" . $v['sunset'] . "\n"; $contentStr .= "经度:" . $v['longitude'] . "\n"; $contentStr .= "纬度:" . $v['latitude']; } } echo $contentStr;
如果你填寫了自己的apikey,那麼應該可以獲取到所請求的天氣了:
#如果能回傳正常的資料了,那就可以放到你的網域空間裡了。 (公眾平台裡開發者中心填寫的url,該url有連接微信介面等功能)
下面的程式碼是responseMsg的一部分:
public function responseMsg(){ <span style="white-space:pre"> </span>//get post data, May be due to the different environments $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //接收微信发来的XML数据 //extract post data if(!empty($postStr)){ //解析post来的XML为一个对象$postObj $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; //请求消息的用户 $toUsername = $postObj->ToUserName; //"我"的公众号id $keyword = trim($postObj->Content); //用户发送的消息内容 $time = time(); //时间戳 $msgtype = 'text'; //消息类型:文本 $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[%s]]></MsgType> <Content><![CDATA[%s]]></Content> </xml>"; if($postObj->MsgType == 'event'){ //如果XML信息里消息类型为event if($postObj->Event == 'subscribe'){ //如果是订阅事件 $contentStr = "欢迎订阅misaka去年夏天!\n更多精彩内容:http://blog.csdn.net/misakaqunianxiatian"; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgtype, $contentStr); echo $resultStr; exit(); } } $which = mb_substr($keyword, 0, 2, 'UTF-8');//获取要返回什么样的信息 if($which== "翻译"){ //如果要进行翻译 //调用有道翻译API进行翻译 }elseif($which == "天气"){ $wea = $which; $city = str_replace($wea, "", $keyword); $ch = curl_init(); $url = 'http://apis.baidu.com/apistore/weatherservice/cityname?cityname=' . $city; $header = array('apikey: '); //此处的apikey使用自己申请的apikey,填在冒号之后 // 添加apikey到header curl_setopt($ch, CURLOPT_HTTPHEADER , $header); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 执行HTTP请求 curl_setopt($ch , CURLOPT_URL , $url); $res = curl_exec($ch); $res = json_decode($res, true); $contentStr = ""; foreach($res as $k=>$v){ if($k == "retData"){ $contentStr = "城市:" . $v['city'] . "\n"; $contentStr .= "日期:" . $v['date'] . "\n"; $contentStr .= "天气:" . $v['weather'] ."\n"; $contentStr .= "平均气温:" . $v['temp'] . "℃\n"; $contentStr .= "最低气温:" . $v['l_tmp'] ."℃\n"; $contentStr .= "最高气温:" . $v['h_tmp'] . "℃\n"; $contentStr .= "风力:" . $v['WS'] . "\n"; $contentStr .= "风向:" . $v['WD'] . "\n"; $contentStr .= "日出时间:" . $v['sunrise'] . "\n"; $contentStr .= "日落时间:" . $v['sunset'] . "\n"; $contentStr .= "经度:" . $v['longitude'] . "\n"; $contentStr .= "纬度:" . $v['latitude']; } } $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgtype, $contentStr); echo $resultStr; exit(); }else{ $contentStr = "输入翻译XXX可以进行翻译(=・ω・=)\n\n输入天气XX可以查询城市天气"; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgtype, $contentStr); echo $resultStr; exit(); }
完成之後(別忘了填寫apikey) ,你的訂閱號碼裡,輸入天氣上海,那應該可以查到上海當天的天氣了。
