快递查询

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;
