Capacitor Plugins

对于 Ionic 开发者来说，开始使用 Capacitor 相当简单直接。将插件添加到项目与添加项目所需的任何依赖项并无区别。

安装

要安装插件，找到您想使用的插件并使用您的包管理器（如 npm）进行安装：

# 安装 Capacitor 插件
$ npm install @capacitor/camera

使用

安装后，可以将插件导入到组件中，并直接从代码中调用原生功能。

以 Camera 插件为例，首先安装它：

JavaScript

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

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

Angular

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

@Component({...})
export class CameraComponent{
  public imageSrc: string | undefined = '';

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

Vue

<template>
...
</template>

<script setup lang="typescript">
import { ref } from 'vue';
import { Camera, CameraResultType } from '@capacitor/camera';
const imageSrc = ref<string | undefined>('');

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

</script>

React

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

export function CameraComponent() {
  const [imageSrc, setImageSrc] = useState<string | undefined>('');

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