Detailed explanation of how to use Baidu Map API, detailed explanation of how to use api
I recently worked on a project, in which there was a requirement to use Baidu Map for navigation. By consulting relevant information An example is completed with reference to Baidu Map API.
Example 1:
API address: http://developer.baidu.com/map/jsdemo.htm#a1_2
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;font-family:"微软雅黑";}
</style>
<!--调用百度api -->
<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=你的密钥"></script>
<title>地图展示</title>
</head>
<body>
<div id="allmap"></div>
</body>
</html>
<script type="text/javascript">
// 百度地图API功能
var map = new BMap.Map("allmap"); // 创建Map实例
map.centerAndZoom("西安", 5); // 初始化地图,用城市名设置地图中心点
map.addControl(new BMap.MapTypeControl()); //添加地图类型控件
map.setCurrentCity("深圳"); // 设置地图显示的城市 此项是必须设置的
map.enableScrollWheelZoom(true); //开启鼠标滚轮缩放
var point = new BMap.Point(116.404, 39.915);
var marker = new BMap.Marker(point); // 创建点
map.addOverlay(marker); //添加点
map.removeOverlay(marker); //删除点
// 创建地址解析器实例
var myGeo = new BMap.Geocoder();
//批量解析
var adds = ["长沙", "深圳", "香港", "郑州 ", "惠州", "南昌", "赣州", "中山", "阳江", "上海", "无锡", "南京"];
for (var i = 0; i < adds.length; i++) {
myGeo.getPoint(adds[i], function (point) {
if (point) {
var address = new BMap.Point(point.lng, point.lat);
var marker = new BMap.Marker(address);
map.addOverlay(marker);
var opts = {
width: 120, // 信息窗口宽度
height: 70, // 信息窗口高度
title: "项目信息" // 信息窗口标题
}
var infoWindow = new BMap.InfoWindow("<a href='#' target='blank'>查看详情</a>", opts); // 创建信息窗口对象
marker.addEventListener("click", function () {
map.openInfoWindow(infoWindow,address); //开启信息窗口
});
}
}, "深圳市");
}
getBoundary("中国");
function getBoundary(sRegion) {
var bdary = new BMap.Boundary();
bdary.get(sRegion, function (rs) { //获取行政区域
var count = rs.boundaries.length; //行政区域的点有多少个
for (var i = 0; i < count; i++) {
var ply = new BMap.Polygon(rs.boundaries[i], { strokeWeight: 2, strokeColor: "#4A7300", fillColor: "#FFF8DC" }); //建立多边形覆盖物
map.addOverlay(ply); //添加覆盖物
}
});
}
</script>
The effect is as follows:
Example 2:
Baidu Map API is written in JavaScript language. You need to reference the API to the page before using it: Now the new version requires a key, and the old version is used below
Show a simple example of Guangzhou Railway Station:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>百度地图API的使用</title>
<!-- 百度地图API-->
<script src="http://api.map.baidu.com/api?v=1.2" type="text/javascript"></script>
<script type="text/javascript">
function initialize() {
//创建地图实例
var map = new BMap.Map('map');
//创建一个坐标
var point =new BMap.Point(113.264641,23.154905);
//地图初始化，设置中心点坐标和地图级别
map.centerAndZoom(point,15);
}
window.onload = initialize;
</script>
</head>
<body>
<!-- 百度地图地图容器-->
<div id="map" style="width:500px;height:320px"></div>
</body>
</html>
Add controls on the map:
//Add controls
map.addControl(new BMap.MapTypeControl());
MapTypeControl ---------Map type control
CopyrightControl --------Copyright Control
ScaleControl --------Scale control
NavigationControl ------Zoom control
OverviewMapControl ----Thumbnail control
Create annotation:
var marker = new BMap.Marker(point); // 创建标注 map.addOverlay(marker); // 将标注添加到地图中
Create information window:
var infoWindow = new BMap.InfoWindow("I am here"); // 创建信息窗口对象
map.openInfoWindow(infoWindow,point); //开启信息窗口
Baidu map offset:
Longitude correction value: 0.008774687519;
Latitude correction value: 0.00374531687912;

What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AMSession in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

What is the difference between absolute and idle session timeouts?May 03, 2025 am 12:21 AMAbsolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.
What steps would you take if sessions aren't working on your server?May 03, 2025 am 12:19 AMThe server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
