PHP WeChat development Query City Weather _php instance

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

Login to Baidu account, and send a request to obtain Apikey mobile phone. With Apikey, you can follow its example to request City weather. (Can be based on the city Chinese name, pinyin, city number, etc. to inquire)

You can do the test locally now, after the request is completed, and then into your own domain namespace script.
Test the script for example: (note apikey fill in the application)

Header (' Content-type:text/html;charset=utf-8 '); $ch = Curl_init (); $url = ' http://apis.baidu.com/apistore/ Weatherservice/cityname?cityname= Shanghai '; $header = Array (' Apikey: ',//Your apikey);//Add Apikey to Headercurl_setopt ($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 "
";p Rint_r ($res); echo"
"; $contentStr =" "; foreach ($res as $k = = $v) {if ($k = =" Retdata ") {$contentStr =" City: ". $v [' City ']. "\ n"; $contentStr. = "Date:". $v [' Date ']. "\ n"; $contentStr. = "Weather:". $v [' Weather ']. " \ n "; $contentStr. = "Average temperature:". $v [' temp ']. "℃\n"; $contentStr. = "Lowest 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 in your apikey, you should be able to get the requested weather:

If you can return to the normal data, then you can put it in your domain name space. (The URL of the developer center in the public platform, which has a connection interface and other functions)
If you do not understand the following code or first contact development, you can refer to my previous article: http://www.php.net/article/87252.htm

The following code is part of responsemsg:

Public Function responsemsg () { Get post data, due to the different environments $postStr = $GLOBALS ["Http_raw_post_data"]; Receives the outgoing XML data//extract the post data if (!empty ($POSTSTR)) {//parses the post to XML as an object $postobj $POSTOBJ = simplexml_load_string ($po   Ststr, ' simplexmlelement ', libxml_nocdata); $fromUsername = $POSTOBJ->fromusername; User $toUsername for Request message = $POSTOBJ->tousername; The "I" public number id $keyword = Trim ($postObj->content); The message content sent by the user $time = time (); Timestamp $msgtype = ' text '; Message type: Text $TEXTTPL = "

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

The above is the whole content of this article, I hope that everyone's learning has helped, but also hope that we support the script home.
