php微信公众号开发之快递查询

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
/**

//define your token
define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
//$wechatObj->valid();
$wechatObj->responseMsg();

 //valid signature , option

 exit;
 }
 }

 {
 //get post data, May be due to the different environments

 //extract post data
