Can uniapp call Baidu Maps?

uni-app is a cross-platform application development framework that supports development using Vue.js. It also supports the development of multiple small program platforms and H5 applications. It is very convenient to use Baidu Map in uni-app. You only need to call the relevant interface through Baidu Map API.

Specifically, uni-app implements map calling by introducing the Baidu Map JavaScript API into the project. In the Baidu Map JavaScript API, there are many map functional interfaces available for developers to use. For example, you can obtain the current location, search for surrounding locations, draw heat maps, annotate markers, etc. through Baidu Map API.

For uni-app developers, you can use Baidu Maps in your project through the following steps:

1. Apply for API Key on Baidu Map Open Platform:

at Before using the Baidu Map JavaScript API, you need to apply for an API Key on the Baidu Map Open Platform. The steps to obtain the API Key are as follows:

• Log in to Baidu Map Open Platform: http://lbsyun.baidu.com/
• Create an application: Enter the management console and go to the application list Click "Create Application" and fill in relevant information, such as application name, application platform, etc. After the creation is completed, you can obtain an API Key.

2. Introduce the Baidu Map JavaScript API into the uni-app project:

In the index.html file of the uni-app project, introduce the Baidu Map JavaScript API. Call relevant interfaces. You can insert the following code into the head tag of the index.html file:

<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的API Key"></script>

Wherein, replace "your API Key" with your own API Key.

3. Call the Baidu map interface in the uni-app project:

After introducing the Baidu map JavaScript API in the index.html file, you can call the relevant Baidu in the uni-app page Map interface. For example, you can use the following code to initialize the map in the uni-app page:

<template>
  <div id="map"></div>
</template>

<script>
  export default {
    onReady() {
      // 创建地图实例
      var map = new BMap.Map("map");

      // 初始化地图，设置中心点坐标和地图级别
      map.centerAndZoom(new BMap.Point(116.404, 39.915), 11);

      // 开启鼠标滚轮缩放
      map.enableScrollWheelZoom(true);
    }
  }
</script>

This code will draw a Baidu map on the page and set it to be centered on Beijing and the map level is 11 map.

In general, the combination of uni-app and Baidu Map is very convenient. You only need to introduce the Baidu Map JavaScript API and call the relevant interfaces to easily realize the development of map applications.
