WeChat development-weather forecast function

This article mainly gives you a detailed introduction to the development of Baidu weather forecast, which has some reference value, interested friends can refer to this article for details about the Baidu weather forecast developed by php, which has some reference value. interested friends can refer to it.

This article provides an example of the php Baidu weather forecast development code for your reference. The details are as follows:

1. apply to log on to Baidu ak:Http://www.php.cn/

 $ Ak, 'location' => $ location, 'output' => $ output); $ querystring = http_build_query ($ querystring_arrays ); // Generate sn $ sn = md5 (urlencode ($ uri. '? '. $ Querystring. $ sk); $ targetUrl = sprintf ($ url, $ ak, urlencode ($ location), $ output, $ sn); $ ch = curl_init (); curl_setopt ($ ch, CURLOPT_URL, $ targetUrl); curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); $ result = curl_exec ($ ch); curl_close ($ ch ); $ result = json_decode ($ result, true); if ($ result ["error"]! = 0) {return $ result ["status"] ;}$ curHour = (int) date ('H', time ()); $ weather = $ result ["results"] [0]; $ weatherArray [] = array ("Title" => $ weather ['currentcity']. "Weather Forecast", "Description" => "", "PicUrl" => "", "Url" => ""); for ($ I = 0; $ I
 
  
$ Weather ["weather_data"] [$ I] ["data"]. "\ n ". $ weather ["weather_data"] [$ I] ["weather"]. $ weather ["weather_data"] [$ I] ["wind"]. $ weather ["weather_data"] [$ I] ["temperature"], "Description" => "", "PicUrl" => ($ curHour> = 6) & ($ curHour <18 ))? $ Weather ["weather_data"] [$ I] ["dayPictureUrl"]: $ weather ["weather_data"] [$ I] ["nightPictureUrl"], "URL" => "");} return $ weatherArray ;}
 

3. implement weather message events

 ResponseMsg ();} else {$ wechatObj-> valid ();} class wechatCallbackapiTest {// verify the signature public function valid () {$ echoStr = $ _ GET ["echostr"]; if ($ this-> checkSignature () {header ('content-type: text'); echo $ echoStr; exit ;}} public function checkSignature () {$ signature =$ _ GET ["signature"]; $ timestamp =$ _ GET ["timestamp"]; $ nonce = $ _ GET ["nonce"]; $ token = TOKEN; $ tmpArr = array ($ token, $ timestamp, $ non Ce); sort ($ tmpArr); $ tmpStr = implode ($ tmpArr); $ tmpStr = sha1 ($ tmpStr); if ($ tmpStr = $ signature) {return true;} else {return false;} // response message public function responseMsg () {$ postStr = $ GLOBALS ["HTTP_RAW_POST_DATA"]; if (! Empty ($ postStr) {$ this-> logger ("R ". $ postStr); $ postObj = simplexml_load_string ($ postStr, 'simplexmlelement', LIBXML_NOCDATA); $ RX_TYPE = trim ($ postObj-> MsgType ); // switch ($ RX_TYPE) {case "event": $ result = $ this-> receiveEvent ($ postObj); break; case "text ": $ result = $ this-> deleetext ($ postObj); break; default: $ result = "unknown msg type :". $ RX_TYPE; break;} echo $ result;} else {echo ""; Exit ;}// public function receiveEvent ($ object) {$ content = ""; switch ($ object-> Event) {case "subscribe ": $ content = "Welcome to Nicky's public account"; $ content. = (! Empty ($ object-> EventKey ))? ("\ N from the QR code scenario ". str_replace ("qrscene _", "", $ object-> EventKey): ""; break; case "unsubscribe": $ content = "cancel follow"; break ;} $ result = $ this-> transmitText ($ object, $ content); return $ result;} // receives the text message public function paietext ($ object) {$ keyword = trim ($ object-> Content); // if (strstr ($ keyword, "weather") {$ city = str_replace ('weather ', '', $ keyword); include (" weather. php "); $ content = getWeatherInfo ($ cit Y) ;}$ result = $ this-> transmitNews ($ object, $ content); return $ result;} // reply to the public function transmitNews ($ object, $ newsArray) {if (! Is_array ($ newsArray) {return;} $ itemTpl ="
    
  <! [CDATA [% s]>   
  %s
     
  %s
     
  %s
    
 "; $ Item_str =" "; foreach ($ newsArray as $ item) {$ item_str. = sprintf ($ itemTpl, $ item ['title'], $ item ['description'], $ item ['picurl'], $ item ['URL']);} $ xmlTpl ="
  
  %s
   
  %s
   
  
   
% S

  % S$ Item_str 
 "; $ Result = sprintf ($ xmlTpl, $ object-> FromUserName, $ object-> ToUserName, time (), count ($ newsArray); return $ result ;} // public function logger ($ log_content) {if (isset ($ _ SERVER ['http _ appname']) {// SAE sae_set_display_errors (false ); sae_debug ($ log_content); sae_set_display_errors (true);} else if ($ _ SERVER ['remote _ ADDR ']! = "127.0.0.1") {// LOCAL $ max_size = 10000; $ log_filename = "log. xml "; if (file_exists ($ log_filename) and (abs (filesize ($ log_filename) >$ max_size) {unlink ($ log_filename);} file_put_contents ($ log_filename, date ('H: I: s '). "". $ log_content. "\ r \ n", FILE_APPEND) ;}}?>
