ionic+vue+capacitor系列笔记--03项目使用Native插件

话不多说，直接上代码

下载依赖

npm install @capacitor/camera

添加权限配置代码到安卓文件夹里的 AndroidManifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

使用代码

import { Camera, CameraResultType } from '@capacitor/camera';

const takePicture = async () => {
  const image = await Camera.getPhoto({
    quality: 90,
    allowEditing: true,
    resultType: CameraResultType.Uri
  });

  // image.webPath will contain a path that can be set as an image src.
  // You can access the original file using image.path, which can be
  // passed to the Filesystem API to read the raw data of the image,
  // if desired (or pass resultType: CameraResultType.Base64 to getPhoto)
  var imageUrl = image.webPath;

  // Can be set to the src of an image now
  imageElement.src = imageUrl;
};

2.app-launcher插件--跳转其他应用程序

npm install @capacitor/app-launcher

代码 com.getcapacitor.myapp 要改为我们需要跳转的APP package name

import { AppLauncher } from "@capacitor/app-launcher/dist/esm/index"; // 这个和官方文档的不一样，文档里写的是不用
async function openvOtherApp() {
  const { value } = await AppLauncher.canOpenUrl({
    url: "com.getcapacitor.myapp",
  });
  console.log("test: Can open url: ", value);
  if (value) {
    await AppLauncher.openUrl({
      url: "com.getcapacitor.myapp://page?id=portfolio",
    });
  }
}
openvOtherApp();

同步插件和代码

ionic cap sync

功能测试

会弹出一个申请权限的弹框，然后允许以后就会跳转到相应的应用程序里

3.Device 获取设备信息

npx cap sync

代码

import { Device } from "@capacitor/device/dist/esm/index";
async function getDeviceInfo() {
  const info = await Device.getInfo();
    console.log(info);
}
async function getBatteryInfo() {
 const info = await Device.getBatteryInfo();
  console.log(info);
}

4.Toast 展示Message

npm install @capacitor/toast
npx cap sync

代码

import { Toast } from '@capacitor/toast/dist/esm/index';
async function showToast() {
 await Toast.show({
    text: 'Hello!',
  });
}

5.使用 keychin插件(此步骤待继续补充)

https://ionicframework.com/docs/native/keychain

下载依赖

$ npm install cordova-plugin-ios-keychain 
$ npm install @awesome-cordova-plugins/keychain 

在代码中使用插件

import { Keychain } from '@awesome-cordova-plugins/keychain/ngx';
let keychain : Keychain = new Keychain();
keychain.set('myKeychin', 'value').then(() => {
  keychain.get('myKeychin')
    .then(value => console.log('myKeychin Got value', value))
    .catch(err => console.log('myKeychin Error getting', err));
})
.catch(err => console.error('Error setting', err));

发现这个东西居然依赖angular/core

npm install @angular/core

打包同步代码

$ ionic cap sync

遇到报错

解决报错

ionic cap update
ionic cap sync

遇到不兼容报错 Found 1 incompatible Cordova plugin for android, skipped install

看了文档：
https://ionicframework.com/blog/thanks-to-capacitor-ive-fallen-in-love-with-mobile-development-again/

[capacitor] [info] Found 1 incompatible Cordova plugin for android, skipped install:
[capacitor]        cordova-plugin-ios-keychain@3.0.1

6.待继续添加

欢迎路过的小哥哥小姐姐们提出更好的意见哇~~
