這篇文章主要介紹微信開(kāi)發(fā)之如何快速查詢城市天氣,文中介紹的非常詳細(xì),具有一定的參考價(jià)值,感興趣的小伙伴們一定要看完!
在青縣等地區(qū),都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局,加強(qiáng)發(fā)展的系統(tǒng)性、市場(chǎng)前瞻性、產(chǎn)品創(chuàng)新能力,以專注、極致的服務(wù)理念,為客戶提供成都網(wǎng)站制作、成都網(wǎng)站設(shè)計(jì)、外貿(mào)營(yíng)銷網(wǎng)站建設(shè) 網(wǎng)站設(shè)計(jì)制作按需開(kāi)發(fā)網(wǎng)站,公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),品牌網(wǎng)站制作,營(yíng)銷型網(wǎng)站,成都外貿(mào)網(wǎng)站建設(shè),青縣網(wǎng)站建設(shè)費(fèi)用合理。微信http://www.php.cn/php/php-tp-demand.html" target="_blank">查詢城市天氣,首先,你需要找到一個(gè)獲取天氣的API,此處,用的是百度的apistore,可以去百度申請(qǐng)和使用API。
登錄百度賬號(hào),并用手機(jī)發(fā)送請(qǐng)求獲取apikey。有了apikey,可以按照它的示例來(lái)請(qǐng)求城市天氣了。(可以按照城市中文名,拼音,城市編號(hào)等來(lái)查詢)
你可以現(xiàn)在本地做測(cè)試,請(qǐng)求完成之后,再放到自己的域名空間的腳本里。
測(cè)試的腳本例如:(注意apikey填寫自己申請(qǐng)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); // 執(zhí)行HTTP請(qǐng)求 curl_setopt($ch , CURLOPT_URL , $url); $res = curl_exec($ch); $res = json_decode($res, true); echo "<pre>"; print_r($res); echo "</pre>"; $contentStr = ""; foreach($res as $k=>$v){ if($k == "retData"){ $contentStr = "城市:" . $v['city'] . "\n"; $contentStr .= "日期:" . $v['date'] . "\n"; $contentStr .= "天氣:" . $v['weather'] ."\n"; $contentStr .= "平均氣溫:" . $v['temp'] . "℃\n"; $contentStr .= "最低氣溫:" . $v['l_tmp'] ."℃\n"; $contentStr .= "高氣溫:" . $v['h_tmp'] . "℃\n"; $contentStr .= "風(fēng)力:" . $v['WS'] . "\n"; $contentStr .= "風(fēng)向:" . $v['WD'] . "\n"; $contentStr .= "日出時(shí)間:" . $v['sunrise'] . "\n"; $contentStr .= "日落時(shí)間:" . $v['sunset'] . "\n"; $contentStr .= "經(jīng)度:" . $v['longitude'] . "\n"; $contentStr .= "緯度:" . $v['latitude']; } } echo $contentStr;
如果你填寫了自己的apikey,那么應(yīng)該能獲取到所請(qǐng)求的天氣了:
如果能返回正常的數(shù)據(jù)了,那么就可以放到你的域名空間里了。(公眾平臺(tái)里開(kāi)發(fā)者中心填寫的url,該url有連接微信接口等功能)
public function responseMsg(){ <span style="white-space:pre"> </span>//get post data, May be due to the different environments $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //接收微信發(fā)來(lái)的XML數(shù)據(jù) //extract post data if(!empty($postStr)){ //解析post來(lái)的XML為一個(gè)對(duì)象$postObj $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; //請(qǐng)求消息的用戶 $toUsername = $postObj->ToUserName; //"我"的公眾號(hào)id $keyword = trim($postObj->Content); //用戶發(fā)送的消息內(nèi)容 $time = time(); //時(shí)間戳 $msgtype = 'text'; //消息類型: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信息里消息類型為event if($postObj->Event == 'subscribe'){ //如果是訂閱事件 $contentStr = "歡迎訂閱misaka去年夏天!\n更多精彩內(nèi)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');//獲取要返回什么樣的信息 if($which== "翻譯"){ //如果要進(jìn)行翻譯 //調(diào)用有道翻譯API進(jìn)行翻譯 }elseif($which == "天氣"){ $wea = $which; $city = str_replace($wea, "", $keyword); $ch = curl_init(); $url = 'http://apis.baidu.com/apistore/weatherservice/cityname?cityname=' . $city; $header = array('apikey: '); //此處的apikey使用自己申請(qǐng)的apikey,填在冒號(hào)之后 // 添加apikey到header curl_setopt($ch, CURLOPT_HTTPHEADER , $header); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 執(zhí)行HTTP請(qǐng)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 .= "天氣:" . $v['weather'] ."\n"; $contentStr .= "平均氣溫:" . $v['temp'] . "℃\n"; $contentStr .= "最低氣溫:" . $v['l_tmp'] ."℃\n"; $contentStr .= "高氣溫:" . $v['h_tmp'] . "℃\n"; $contentStr .= "風(fēng)力:" . $v['WS'] . "\n"; $contentStr .= "風(fēng)向:" . $v['WD'] . "\n"; $contentStr .= "日出時(shí)間:" . $v['sunrise'] . "\n"; $contentStr .= "日落時(shí)間:" . $v['sunset'] . "\n"; $contentStr .= "經(jīng)度:" . $v['longitude'] . "\n"; $contentStr .= "緯度:" . $v['latitude']; } } $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgtype, $contentStr); echo $resultStr; exit(); }else{ $contentStr = "輸入翻譯XXX可以進(jìn)行翻譯(=?ω?=)\n\n輸入天氣XX可以查詢城市天氣"; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgtype, $contentStr); echo $resultStr; exit(); }
完成之后(別忘了填寫apikey),你的訂閱號(hào)里,輸入天氣上海,那么應(yīng)該能查到上海當(dāng)天的天氣了。
