PHP WeChat development to query city weather, php query city weather

PHP WeChat query city weather, first, you need to find an API to get the weather, here, I use It is Baidu’s apistore. The URL to apply for and use the API: http://apistore.baidu.com/apiworks/servicedetail/112.html

Log in to your Baidu account and use your mobile phone to send a request to obtain the apikey. With apikey, you can follow its example to request city weather. (You can search according to the city’s Chinese name, pinyin, city number, etc.)

You can do the test locally now, and after the request is completed, put it in the script of your own domain name space.
Test script example: (note that apikey fills in the one you applied for)

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;

If you fill in your own apikey, you should be able to get the requested weather:

If normal data can be returned, then it can be placed in your domain name space. (The url filled in by the developer center in the public platform. This url has functions such as connecting to the WeChat interface)
If you can’t understand the code below or it’s your first time contacting WeChat development, you can refer to my previous article: http://www.bkjia.com/article/87252.htm

The following code is part of responseMsg:

 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&#63;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(=&#12539;ω&#12539;=)\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();
  }

​

After completion (don’t forget to fill in the apikey), enter the weather Shanghai in your subscription account, and you should be able to check the weather in Shanghai that day.
