PHP微信开发之查询城市天气

时间:2024-3-1 19:20     作者:韩俊     分类: PHP


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:http://apistore.baidu.com/apiworks/servicedetail/112.html

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:http://www.maopiaopiao.com/article/87252.htm

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・=)nn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。
