PHP micro-Credit development query City Weather _php Example

PHP micro-letter Query City weather, first of all, you need to find a weather API, here, I use Baidu's Apistore, application and use the API URL: http://apistore.baidu.com/apiworks/servicedetail/112.html

Login Baidu account, and the mobile phone to send requests to obtain apikey. With Apikey, you can follow its example to request City weather. (can be queried according to the city's Chinese name, pinyin, city number, etc.)

You can now test locally, after the request is completed, and then put into your own domain name space in the script.
Test Scripts For example: (note apikey to fill in their own application)

Header (' Content-type:text/html;charset=utf-8 ');
$ch = Curl_init ();
$url = ' http://apis.baidu.com/apistore/weatherservice/cityname?cityname= Shanghai ';
$header = Array (' Apikey: ',//Your apikey);
Add Apikey to Header curl_setopt ($ch, Curlopt_httpheader, $header);
curl_setopt ($ch, Curlopt_returntransfer, 1);
Execute HTTP request 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 = "city:". $v [' Cities '].
 "\ n"; $contentStr. = "Date:". $v [' Date '].
 "\ n"; $contentStr. = "Weather:". $v [' Weather ']. "
 \ n "; $contentStr. = "Average temperature:". $v [' temp '].
 "℃\n"; $contentStr. = "Minimum temperature:". $v [' l_tmp ']. "
 ℃\n "; $contentStr. = "Maximum temperature:". $v [' h_tmp '].
 "℃\n"; $contentStr. = "Wind:". $v [' WS '].
 "\ n"; $contentStr. = "Wind Direction:". $v [' WD '].
 "\ n"; $contentStr. = "Sunrise time:". $v [' Sunrise '].
 "\ n"; $contentStr. = "Sunset time:". $v [' Sunset '].
 "\ n"; $contentStr. = "Longitude:" . $v [' Longitude '].
 "\ n"; $contentStr. = "Latitude:".
 $v [' latitude '];

 } Echo $contentStr;

If you fill out your own apikey, you should be able to obtain the requested weather:

If you can return to normal data, then you can put it into your domain space. (the URL that the developer center fills in the public platform, which has the function of connecting the micro-letter interface, etc.)
If you do not understand the following code or first contact with the micro-credit development, you can refer to my previous article: http://www.jb51.net/article/87252.htm

The following code is part of the responsemsg:

   Echo $resultStr;
  Exit (); } $which = Mb_substr ($keyword, 0, 2, ' UTF-8 ');//Get what information to return if ($which = = "Translate") {//If you want to translate//call Youdao translation API for translation}e
  Lseif ($which = = "Weather") {$wea = $which;

  $city = Str_replace ($wea, "", $keyword);
  $ch = Curl_init (); $url = ' http://apis.baidu.com/apistore/weatherservice/cityname?cityname= '.
  $city; $header = Array (' Apikey: ');
  The apikey here use the apikey of their own application, filled in after the colon///Add Apikey to Header curl_setopt ($ch, Curlopt_httpheader, $header);
  curl_setopt ($ch, Curlopt_returntransfer, 1);

  $res = curl_exec ($ch);
  $res = Json_decode ($res, true);
  $CONTENTSTR = ""; foreach ($res as $k => $v) {if ($k = = "Retdata") {$contentStr = "city:". $v [' Cities '].

  Echo $resultStr;

  Exit ();
  }else{$contentStr = "input translation xxx can be translated (= Ω =) \ n \ nplease Enter the weather xx can query the city weather";
  $RESULTSTR = sprintf ($TEXTTPL, $fromUsername, $toUsername, $time, $msgtype, $CONTENTSTR);
  Echo $resultStr;
  Exit ();

 }

After the completion (don't forget to fill in the Apikey), your subscription number, enter the weather in Shanghai, then you should be able to find the weather in Shanghai that day.
