微信開發學習：輸入城市+天氣接收天氣預報，非非非非常好玩

這次實踐一下這篇 http://www.jb51.net/article/51923.htm
輸入城市+天氣四個字，接收天氣預報，資料來源是百度天氣預報介面。原來的程式碼功能多，比較複雜，我精簡了一下，相對容易看懂。
完成後的效果：
wx_token_read.php檔案：
<?php //裝載模板檔案 include_once("wx_tq_tpl.php"); //獲取微信傳送資料 $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //返回回覆資料 if (!empty($postStr)) { //解析資料 $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); //傳送訊息方ID $fromUsername = $postObj->FromUserName; //接收訊息方ID $toUsername = $postObj->ToUserName; //訊息型別 $form_MsgType = $postObj->MsgType; //事件訊息 if ($form_MsgType == "text") { //獲取使用者傳送的文字內容 $form_Content = trim($postObj->Content); if (!empty($form_Content)) { $city = ""; if (substr_count($form_Content, '天氣') != 0 && $form_Content != '天氣') { $geshu = substr_count($form_Content, '天氣'); $t = explode("天氣", $form_Content); for ($i = 0; $i <= $geshu; $i++) { if ($t[$i] != '') { $city = $t[$i]; } break; } } if ($city == "") { $resultStr = "請輸入 城市+天氣"; } else { $mykey = "**************"; // 輸入自己的百度key $url = "http://api.map.baidu.com/telematics/v3/weather?location=" . $city . "&output=json&ak=" . $mykey; $output = file_get_contents($url); $contentStr = json_decode($output, true); if ($contentStr['status'] == 'success') { $T[0]['Title'] = $contentStr['date'] . " " . $contentStr['results'][0]['currentCity'] . "天氣"; $T[0]['Description'] = $contentStr['results'][0]['weather_data'][0]['temperature']." ".$contentStr['results'][0]['weather_data'][0]['weather'] ."

" " . $contentStr['results'][0]['weather_data'][$aaa]['temperature'] . " " . $contentStr['results'][0]['weather_data'][$aaa]['weather'] . " " . $contentStr['results'][0]['weather_data'][$aaa]['wind']; $T[$i]['Description'] = ""; $T[$i]['PicUrl'] = $contentStr['results'][0]['weather_data'][$aaa]['dayPictureUrl']; $T[$i]['Url'] = $contentStr['results'][0]['weather_data'][$aaa]['dayPictureUrl']; $aaa++; } $resultStr = sprintf($tqTpl, $fromUsername, $toUsername, time(), "news", $T[0]['Title'], $T[0]['Description'], $T[0]['PicUrl'], $T[0]['Url'], $T[1]['Title'], $T[1]['Description'], $T[1]['PicUrl'], $T[1]['Url'], $T[2]['Title'], $T[2]['Description'], $T[2]['PicUrl'], $T[2]['Url'], $T[3]['Title'], $T[3]['Description'], $T[3]['PicUrl'], $T[3]['Url'], $T[4]['Title'], $T[4]['Description'], $T[4]['PicUrl'], $T[4]['Url']); } } echo $resultStr; exit; } } elseif ($form_MsgType == "event")// 接收到事件 { //獲取事件型別 $form_Event = $postObj->Event; //訂閱事件 if ($form_Event == "subscribe") // 接收到的事件為：關注 { //回覆歡迎文字訊息 $return_str = "歡迎使用天氣預報aaa\n"; $msgType = "text"; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, time(), $msgType, $return_str); echo $resultStr; exit; } } } ?>
xml模板檔案 wx_tq_tpl.php：
<?php $tqTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[%s]]></MsgType> <ArticleCount>5</ArticleCount> <Articles> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[%s]]></Description> <PicUrl><![CDATA[%s]]></PicUrl> <Url><![CDATA[%s]]></Url> </item> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[%s]]></Description> <PicUrl><![CDATA[%s]]></PicUrl> <Url><![CDATA[%s]]></Url> </item> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[%s]]></Description> <PicUrl><![CDATA[%s]]></PicUrl> <Url><![CDATA[%s]]></Url> </item> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[%s]]></Description> <PicUrl><![CDATA[%s]]></PicUrl> <Url><![CDATA[%s]]></Url> </item> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[%s]]></Description> <PicUrl><![CDATA[%s]]></PicUrl> <Url><![CDATA[%s]]></Url> </item> </Articles> </xml> "; ?>
接收到的百度天氣預報資料，修改程式碼時用到：
