Title: Methods and code examples for implementing bus inquiry and subway navigation in UniApp

Introduction:
With the development of cities and the increase in people’s travel needs, Bus inquiry and subway navigation have become important transportation functions. In UniApp, we can use its rich plug-ins and components to implement bus inquiry and subway navigation functions. This article will introduce the specific ways to implement bus query and subway navigation in UniApp, and provide code examples for reference.

1. Implementation of bus query function

1. Install plug-in: BMap (using Baidu Map API)

First, in the manifest under the UniApp project directory. Add "BMap":"^0.0.4" under "dependencies" in the json file, and then execute npm install to install the plug-in.

2. Introduce the plug-in and initialize the map object

Introduce the BMap plug-in and initialize the map object in the page where you need to use the bus query function.

import BMap from 'jm-bmap';
BMap.init({ ak: 'your ak' });

3. Implementing the bus query function

In the page where the bus query results need to be displayed, we can perform the bus query by calling the method provided by the plug-in.

// 具体的公交查询方法
BMap.searchTransit({
  origin: '起点位置',
  destination: '终点位置',
  success(data) {
    // 查询成功后的回调函数，处理查询结果
    console.log(data);
  },
  fail(err) {
    // 查询失败后的回调函数，处理失败情况
    console.error(err);
  }
});

2. Implementation of subway navigation function

1. Install plug-in: LMap (using Amap API)

Manifest in the UniApp project directory. Add "LMap":"^1.0.2" under "dependencies" in the json file, and then execute npm install to install the plug-in.

2. Introduce the plug-in and initialize the map object

Introduce the LMap plug-in and initialize the map object in the page where you need to use the subway navigation function.

import LMap from 'jm-amap';
LMap.init({ key: 'your key' });

3. Implementing the subway navigation function

In the page that needs to display the subway navigation results, we can perform subway navigation by calling the method provided by the plug-in.

// 具体的地铁导航方法
LMap.getWalkingRoute({
  origin: '起点位置',
  destination: '终点位置',
  success(data) {
    // 导航成功后的回调函数，处理导航结果
    console.log(data);
  },
  fail(err) {
    // 导航失败后的回调函数，处理失败情况
    console.error(err);
  }
});

Conclusion:
By using the plug-ins and components provided by UniApp, we can easily implement bus inquiry and subway navigation functions. The above code is just a simple example. In actual use, it may need to be adjusted appropriately according to specific needs. I hope this article can help you, and I wish you can write powerful and practical bus query and subway navigation functions.
