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 = "jb51.net"; //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){ $picurl = "http://jb51.net/weixin/images/640_".$FromUserName.".png"; }else{ $picurl = "http://jb51.net.net/weixin/images/80_".$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。
