Project requirements: Get the distance between two points according to the latitude and longitude, I use the api of Tencent map here
php code:
/**
* Use Tencent map api
* Calculate the distance between two geographic coordinates
*/
function getDistance(){
$key ='Fill in your key'; //Tencent map develops your own application
$mode ='driving'; //driving (driving), walking (walking)
$from ='Fill in your starting point coordinates'; //For example: 39.14122,117.14428
$to ='Start point coordinates; End point coordinates'; //For example (format: end point coordinates; start point coordinates): 39.10149,117.10199;39.14122,117.14428
$url = 'https://apis.map.qq.com/ws/distance/v1/?mode='.$mode.'&from='.$from.'&to='.$to.'&key='.$key;
$info = file_get_contents($url);
$info = json_decode($info, true);
print_r($info);
}1234567891011121314
Print result:
Remarks:
-
For parameter analysis of request parameters and response results, you can see the official document: Tencent Map Official Document
Tips:
-
To calculate the distance between two points, you must get the latitude and longitude in advance, right, here I don’t recommend that you use the Baidu map api to get the latitude and longitude. It is a bit inaccurate. I personally stepped on it.
