本文实例为大家分享了php微信公众号开发之快递查询的具体代码，供大家参考，具体内容如下

快递查询

• 数组用法
• foreach
  

查询接口是：爱快递：https://www.aikuaidi.cn/api/

核心代码如下：

$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; $toUsername = $postObj->ToUserName; $type = $postObj->MsgType; $customrevent = $postObj->Event; $latitude = $postObj->Location_X; $longitude = $postObj->Location_Y; $keyword = trim($postObj->Content); $time = time(); $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[%s]]></MsgType> <Content><![CDATA[%s]]></Content> <FuncFlag>0</FuncFlag> </xml>"; switch ($type) { case "text"; $status=array('0'=>'查询出错','1'=>'暂无记录','2'=>'在途中','3'=>'派送中','4'=>'已签收','5'=>'拒收','6'=>'疑难件','7'=>'退回');//构建快递状态数组 $kuaidiurl="http://www.aikuaidi.cn/rest/?key=ff4735a30a7a4e5a8637146fd0e7cec9&order={$keyword}&id=shentong&show=xml";//快递地址 $kuaidistr=file_get_contents($kuaidiurl);//读入文件 $kuaidiobj=simplexml_load_string($kuaidistr);//xml解析 $kuaidistatus = $kuaidiobj->Status;//获取快递状态 $kuaistr=strval($kuaidistatus);//对象转换为字符串 $contentStr0 =$status[$kuaistr];//根据数组返回 foreach ($kuaidiobj->Data->Order as $a) { foreach ($a->Time as $b) { foreach ($a->Content as $c) { $m.="{$b}{$c}";} } } //遍历获取快递时间和事件 $contentStr="你的快递单号{$keyword}{$contentStr0}{$m}"; break; default; $contentStr ="此项功能尚未开发"; } $msgType="text"; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr;

index.php整体代码如下：

<?php/** * wechat php test *///define your tokendefine("TOKEN", "weixin");$wechatObj = new wechatCallbackapiTest();//$wechatObj->valid();$wechatObj->responseMsg();class wechatCallbackapiTest{ public function valid() { $echoStr = $_GET["echostr"]; //valid signature , option if($this->checkSignature()){ echo $echoStr; exit; } } public function responseMsg() { //get post data, May be due to the different environments $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //extract post data if (!empty($postStr)){ $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; $toUsername = $postObj->ToUserName; $type = $postObj->MsgType; $customrevent = $postObj->Event; $latitude = $postObj->Location_X; $longitude = $postObj->Location_Y; $keyword = trim($postObj->Content); $time = time(); $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[%s]]></MsgType> <Content><![CDATA[%s]]></Content> <FuncFlag>0</FuncFlag> </xml>"; switch ($type) { case "text"; $status=array('0'=>'查询出错','1'=>'暂无记录','2'=>'在途中','3'=>'派送中','4'=>'已签收','5'=>'拒收','6'=>'疑难件','7'=>'退回');//构建快递状态数组 $kuaidiurl="http://www.aikuaidi.cn/rest/?key=ff4735a30a7a4e5a8637146fd0e7cec9&order={$keyword}&id=shentong&show=xml";//快递地址 $kuaidistr=file_get_contents($kuaidiurl);//读入文件 $kuaidiobj=simplexml_load_string($kuaidistr);//xml解析 $kuaidistatus = $kuaidiobj->Status;//获取快递状态 $kuaistr=strval($kuaidistatus);//对象转换为字符串 $contentStr0 =$status[$kuaistr];//根据数组返回 foreach ($kuaidiobj->Data->Order as $a) { foreach ($a->Time as $b) { foreach ($a->Content as $c) { $m.="{$b}{$c}";} } } //遍历获取快递时间和事件 $contentStr="你的快递单号{$keyword}{$contentStr0}{$m}"; break; default; $contentStr ="此项功能尚未开发"; } $msgType="text"; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; }else { echo ""; exit; } } private function checkSignature() { $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); sort($tmpArr); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } }}?>
