php微信公众开发之获取周边酒店信息的方法

  本文实例讲述了php微信公众开发之获取周边酒店信息的方法。分享给大家供大家参考。具体分析如下:

  关注微信公众之后发送回复地理位置信息,即可回复周边附近的酒店信息列表,下面我就来给各位介绍利用php是怎么实现这个功能,希望全子对大家有帮助.代码如下:

  

复制代码 代码如下:
<?php

  //将提交过来的信息接收

  $signature = $_GET['signature'];

  $timestamp = $_GET['timestamp'];

  $nonce = $_GET['nonce'];

  $echostr = $_GET['echostr'];

  $token = "glzy8.com";

  //判断接入网站

  //进行字典排序

  $arr = array($token,$timestamp,$nonce);

  sort($arr);

  //完成字符串的拼接和sha1加密

  $result = sha1(join($arr));

  //判断生成的字符串和$signature是否相等,如果相等,直接输出$echostr,这样网站接入成功

  if($result==$signature){

  echo $echostr;

  }

  //接收微信公众账号接收到的信息

  $poststr = $GLOBALS["HTTP_RAW_POST_DATA"];

  $xmlObj = simplexml_load_string($poststr,'SimpleXMLElement',LIBXML_NOCDATA);

  $ToUserName = $xmlObj->ToUserName;

  $FromUserName = $xmlObj->FromUserName;

  $CreateTime = $xmlObj->CreateTime;

  $MsgType = $xmlObj->MsgType;

  $Content = $xmlObj->Content;

  if($MsgType=='location'){

  $Location_X = $xmlObj->Location_X;

  $Location_Y = $xmlObj->Location_Y;

  $Scale = $xmlObj->Scale;

  $Label = $xmlObj->Label;

  $urlstr = "http://api.map.baidu.com/place/v2/search?&query=酒店&location=".$Location_X.",".$Location_Y."&radius=5000&output=json&ak=DESY8unmZnUlLB0mlowjuiRr";  //此处ak参数需要个人的百度开发序列号,自己去百度申请下就好了

  $jsonstr = file_get_contents($urlstr);

  $json = json_decode($jsonstr,true);

  $pic_640 = "http://api.map.baidu.com/staticimage?width=640&height=320¢er=".$Location_Y.",".$Location_X."&zoom=15&markers=".$Location_Y.",".$Location_X."&markerStyles=l,";

  $pic_80 = "http://api.map.baidu.com/staticimage?width=80&height=80¢er=".$Location_Y.",".$Location_X."&zoom=15&markers=".$Location_Y.",".$Location_X."&markerStyles=l,";

  $p_640 = file_get_contents($pic_640);

  file_put_contents('./images/640_'.$FromUserName.".png",$p_640);

  $p_80 = file_get_contents($pic_80);

  file_put_contents('./images/80_'.$FromUserName.".png",$p_80);

  echo pic_send($json['results']);

  }

  function pic_send($arr){

  global $ToUserName,$FromUserName;

  $str = "<xml>

  <ToUserName><![CDATA[".$FromUserName."]]></ToUserName>

  <FromUserName><![CDATA[".$ToUserName."]]></FromUserName>

  <CreateTime>".time()."</CreateTime>

  <MsgType><![CDATA[news]]></MsgType>

  <ArticleCount>".count($arr)."</ArticleCount>

  <Articles>";

  foreach($arr as $k=>$v){

  if($k==0){

  $picurl = "http://glzy8.com/weixin/images/640_".$FromUserName.".png";

  }else{

  $picurl = "http://glzy8.com.net/weixin/images/80_".$FromUserName.".png";

  }

  $str .="

  <item>

  <Title><![CDATA[".$v['name']." 地址:".$v['address']." 电话:".$v['telephone']."]]></Title>

  <Description><![CDATA[".$v['name']." 地址:".$v['address']." 电话:".$v['telephone']."]]></Description>

  <PicUrl><![CDATA[".$picurl."]]></PicUrl>

  <Url><![CDATA[http://api.map.baidu.com/place/detail?uid=".$v['uid']."&output=html&src=".$v['name']."&output=html]]></Url>

  </item>";

  }

  $str .= "</Articles></xml>";

  return $str;

  }

  ?>

  希望本文所述对大家的php程序设计有所帮助。
