According to the previous geographical location tutorials, eventually the Tencent map of the WEB service API to write a perfect class, call different interfaces, pay attention to different parameters, because each difference is slightly different, is a direct impact on the display results, so detailed check the official Document WEB Service API documentation
Continue to use TP as a framework for code and instance effects!
Qqmapmodel class:
<?php

Take the Street View interface
Public Function Streetimage ($pano, $otherParam = Array ()) {//max 960x640
$param = Array (
' Size ' => ' 620x380 ',
' Pano ' => $pano,
' Heading ' => 0,
' Pitch ' => 0,
' Key ' => $this->appkey,
);
if (count ($otherParam))
$param = Array_merge ($param, $otherParam);
Return ' Http://apis.map.qq.com/ws/streetview/v1/image? '. Http_build_query ($param);
}
New Static Diagram V2 interface
Public Function Staticmap ($point, $otherParam = Array ()) {
$param = Array (
' Size ' => ' 620*380 ',
' Center ' => $point,
' Zoom ' => 13,
' Format ' => ' PNG ',
' Maptype ' => ' Roadmap ',
' Markers ' => $point,
' Key ' => $this->appkey,
);
if (count ($otherParam))
$param = Array_merge ($param, $otherParam);
Return ' http://apis.map.qq.com/ws/staticmap/v2/? '. Http_build_query ($param);
}
Old static Graph V1 version interface $point parameters first longitude and then latitude and the opposite
public static function Mapimage ($point, $otherParam = Array ()) {
$param = Array (
' Size ' => ' 620*380 ',
' Center ' => $point,
' Zoom ' => 13,
' Format ' => ' PNG ',
' Markers ' => $point,
);
if (count ($otherParam))
$param = Array_merge ($param, $otherParam);
Return ' Http://st.map.qq.com/api? '. Http_build_query ($param);
}
}
The Imagecachemodel class encapsulates a new caching image method:
public static function Getapiimg ($points, $search, $slug = ' marker ') {
$fileName = MD5 ($points);
Self:: $FULL _cache_dir = C (' Public_full_dir '). Self::cache_dir;
$CACHEIMG = self:: $FULL _cache_dir. '/' . $fileName. Self:: $TYPE;
if (file_exists ($CACHEIMG)) {
Return Self::cache_dir. $fileName. Self:: $TYPE;
} else {
$map = qqmapmodel::getinstance (Array (
' Appkey ' => ' CZQBZ-RC53V-2RQPX-UFNBE-VDH2J-DFBFJ '
));
$res = $map->call (qqmapmodel::search_api, Array (
' keyword ' => $search,
' Boundary ' => ' nearby ($points, 1000) "
));
if ($res) {
$IMAGEURL = ';
Switch ($slug) {
Case ' marker ':
$label = Array ();
foreach ($res [' data '] as $data) {
API requires title not to be longer than 13 characters
$label [] = Mb_substr ($data [' title '], 0, ' Utf-8 '). '|' . $data [' Location '] [' lat ']. ',' . $data [' Location '] [' LNG '];
}
$labels = implode (' | ', $label);
$labels = ' border:1|size:10|color:brown|bgcolor:orange| '. $labels;
$IMAGEURL = $map->staticmap ($points, Array (' labels ' => $labels, ' Zoom ' => 15));
Break
Case ' label ':
$marker = Array ();
foreach ($res [' data '] as $data) {
$lat = $data [' Location '] [' lat '];
$LNG = $data [' Location '] [' LNG '];
$marker [] = $lat. ', '. $lng;
}
$markers = implode (' | ', $marker);
$markers = ' color:blue|label:h| '. $markers;
$IMAGEURL = $map->staticmap ($points, Array (' markers ' => $markers, ' Zoom ' => 15));
Break
}
if ($IMAGEURL) {
Self::savecacheimg ($IMAGEURL, $fileName);
Return Self::cache_dir. $fileName. Self:: $TYPE;
}
}
}
Return self::cache_dir ' Default '. Self:: $TYPE;
}
The above code, I mainly called the search interface, and based on the parameters to make the generated map is the icon or the label text to display.
Controller add a Jump URL: (because layout is similar to the previous, here is not written)
Public Function apimapaction () {
Layout (' Layout/apimap ');
$this->display ();
}
Public Function maphotelaction () {
Layout (false);
if (I (' pos ', ') ') {
$target = imagecachemodel::getapiimg (I (' pos '), ' hotel ', ' marker ');
$url = __root__. $target;
Redirect ($url);
}
}
Public Function mapfoodaction () {
Layout (false);
if (I (' pos ', ') ') {
$target = imagecachemodel::getapiimg (I (' pos '), ' Gourmet ', ' label ');
$url = __root__. $target;
Redirect ($url);
}
}
The current Web Service API provides 6 interfaces, including according to address resolution or inverse analysis, as well as coordinate conversion, I do test found that the latitude and longitude of Tencent turned into Baidu after the difference is too large, it seems that the different map APIs between the latitude and longitude of the meaning of the transition. These interfaces are for you to try, Itong ~
