微信公众开发之获取周边酒店信息

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:

<?php
//将提交过来的信息接收
$signature = $_GET[&#39;signature&#39;];
$timestamp = $_GET[&#39;timestamp&#39;];
$nonce = $_GET[&#39;nonce&#39;];
$echostr = $_GET[&#39;echostr&#39;];
$token = "yanjiadong";
//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, &#39;SimpleXMLElement&#39;, LIBXML_NOCDATA);
$ToUserName = $xmlObj->ToUserName;
$FromUserName = $xmlObj->FromUserName;
$CreateTime = $xmlObj->CreateTime;
$MsgType = $xmlObj->MsgType;
$Content = $xmlObj->Content; & nbsp;
if ($MsgType == &#39;location&#39;) {
    $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&center=" . $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&center=" . $Location_Y . "," . $Location_X . "&zoom=15&markers=" . $Location_Y . "," . $Location_X . "&markerStyles=l,";
    $p_640 = file_get_contents($pic_640);
    file_put_contents(&#39;./images/640_&#39; . $FromUserName . ".png", $p_640);
    $p_80 = file_get_contents($pic_80);
    file_put_contents(&#39;./images/80_&#39; . $FromUserName . ".png", $p_80);
    echo pic_send($json[&#39;results&#39;]);
}
function pic_send($arr) {
    global $ToUserName, $FromUserName;
    $str = "<xml> 
<ToUserName><![CDATA[" . $FromUserName . "]]></ToUserName> 
<FromUserName><![CDATA[" . $ToUserName . "]]></FromUserName>

<ArticleCount>" . count($arr) . "</ArticleCount> 
<Articles>";
    foreach ($arr as $k => $v) {
        if ($k == 0) {
            $picurl = "http://yanjiadong.net/weixin/images/640_" . $FromUserName . ".png";
        } else {
            $picurl = "http://yanjiadong.net/weixin/images/80_" . $FromUserName . ".png";
        }
        $str.= "
