php微信查询城市天气,首先,你需要找到一个获取天气的api,此处,我用的是百度的apistore,申请和使用api的网址:
登录百度账号,并用手机发送请求获取apikey。有了apikey,可以按照它的示例来请求城市天气了。(可以按照城市中文名,拼音,城市编号等来查询)
你可以现在本地做测试,请求完成之后,再放到自己的域名空间的脚本里。
测试的脚本例如:(注意apikey填写自己申请的)
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>"; 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;
如果你填写了自己的apikey,那么应该能获取到所请求的天气了:
如果能返回正常的数据了,那么就可以放到你的域名空间里了。(公众平台里开发者中心填写的url,该url有连接微信接口等功能)
如果你看不懂下面的代码或者第一次接触微信开发,可以参考我之前的文章:
下面的代码是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(); }
完成之后(别忘了填写apikey),你的订阅号里,输入天气上海,那么应该能查到上海当天的天气了。
