php WeChat public development method to obtain surrounding hotel information, public surroundings

The example in this article describes the method of obtaining surrounding hotel information through PHP WeChat public development. Share it with everyone for your reference. The specific analysis is as follows:

After following the public on WeChat and sending a reply with geographical location information, you can reply with a list of nearby hotel information. Now I will introduce to you how to implement this function using php. I hope Quanzi can be helpful to everyone. The code is as follows:

Copy code The code is as follows:

//Receive the submitted information
$signature = $_GET['signature'];
$timestamp = $_GET['timestamp'];
$nonce = $_GET['nonce'];
$echostr = $_GET['echostr'];
$token = "jb51.net";
//Determine the access website

//Carry out dictionary sorting
$arr = array($token,$timestamp,$nonce);

sort($arr);

//Complete string splicing and sha1 encryption
$result = sha1(join($arr));
//Determine whether the generated string and $signature are equal. If they are equal, directly output $echostr, so that the website access is successful
if($result==$signature){
echo $echostr;
}

//Receive information received from WeChat public account
$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;

$urlstr = "http://api.map.baidu.com/place/v2/search?&query=hotel&location=".$Location_X.",".$Location_Y."&radius=5000&output=json&ak=DESY8unmZnUlLB0mlowjuiRr"; / /The ak parameter here requires a personal Baidu development serial number. Just go to Baidu to apply for it
$jsonstr = file_get_contents($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 = "


".time()."

".count($arr)."
";
foreach($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 .="





";
}
$str .= "";
return $str;
}
?>
