1. Mobile phone positioning

To implement the mobile phone positioning function in uniapp, you can use uniapp's native API and third-party plug-ins to achieve it. The following will introduce how to use uniapp's native API and third-party plug-ins to implement mobile phone positioning functions.

1. Use uniapp native API to achieve mobile phone positioning

Uniapp provides a series of native APIs, including the API to obtain the user's location: uni.getLocation. The following is a code example of using uni.getLocation to obtain the user's location:

uni.getLocation({
  type: 'gcj02',
  success: function (res) {
    var latitude = res.latitude; // 纬度，浮点数，范围为-90~90
    var longitude = res.longitude; // 经度，浮点数，范围为-180~180
    var speed = res.speed; // 速度，浮点数，单位m/s
    var accuracy = res.accuracy; // 位置精度
  }
});

2. Using third-party plug-ins to achieve mobile phone positioning

In the uniapp plug-in market, there are many excellent ones A map positioning plug-in is available. For example, you can use the plug-in "uniapp-amap" to implement the mobile phone positioning function. The following is a code example for using the "uniapp-amap" plug-in to obtain the user's location:

import amap from 'uniapp-amap';

amap.getLocation({
  success: function (res) {
    var latitude = res.latitude; // 纬度，浮点数，范围为-90~90
    var longitude = res.longitude; // 经度，浮点数，范围为-180~180
    var speed = res.speed; // 速度，浮点数，单位m/s
    var accuracy = res.accuracy; // 位置精度
  }
});

2. Map Navigation

To implement the map navigation function in uniapp, you can also use uniapp's native API and the Third-party plug-ins are implemented. The following will introduce how to use uniapp's native API and third-party plug-ins to implement map navigation functions.

1. Use uniapp native API to implement map navigation

uniapp provides an API to open the mobile phone's native map navigation: uni.openLocation. The following is a code example for using uni.openLocation to open the mobile phone's native map navigation:

uni.openLocation({
  latitude: 23.0231, // 纬度，浮点数，范围为-90~90
  longitude: 113.7308, // 经度，浮点数，范围为-180~180
  name: '目的地',
  address: '地址',
  scale: 18
});

2. Using third-party plug-ins to implement map navigation

In the uniapp plug-in market, there are also many Map navigation related plug-ins are available. For example, you can use the plug-in "uniapp-amap" to implement map navigation functionality. The following is a code example for using the "uniapp-amap" plug-in to open map navigation:

import amap from 'uniapp-amap';

amap.openLocation({
  latitude: 23.0231, // 纬度，浮点数，范围为-90~90
  longitude: 113.7308, // 经度，浮点数，范围为-180~180
  name: '目的地',
  address: '地址',
  scale: 18
});

[Conclusion] By using the uniapp native API or third-party plug-ins, we can easily implement mobile phone positioning and map navigation functions in uniapp. The above code examples can be used as a reference to help developers quickly implement related functions. I hope this article will be helpful to everyone in implementing mobile phone positioning and map navigation functions in uniapp development.
