Question

我搜索了很多关于通过手机摄像头拍摄图像的方法，然后我可以裁剪它，最后我想在firebase上上传图像...

离子2可能吗？或者没办法完成这三个步骤？

Answer 1

您可以使用手机摄像头拍摄图像并裁剪并上传到服务器。有两种选择如下。

https://github.com/jeduan/cordova-plugin-crop
https://ampersandacademy.com/tutorials/ionic-framework-version-2/upload-an-image-to-the-php-server-using-ionic-2-transfer-and-camera-plugin

选项1：

import { Injectable } from '@angular/core';
import { Platform } from 'ionic-angular';
import { Camera, Crop } from 'ionic-native';

@Injectable()
export class CameraService {

  public options: any = {
        allowEdit: true,
        sourceType: Camera.PictureSourceType.SAVEDPHOTOALBUM,
        mediaType: Camera.MediaType.ALLMEDIA,
        destinationType: Camera.DestinationType.FILE_URI
  }

  constructor(public platform: Platform) {}

  // Return a promise to catch errors while loading image
  getMedia(): Promise<any> {
    // Get Image from ionic-native's built in camera plugin
    return Camera.getPicture(this.options)
      .then((fileUri) => {
        // Crop Image, on android this returns something like, '/storage/emulated/0/Android/...'
        // Only giving an android example as ionic-native camera has built in cropping ability
        if (this.platform.is('ios')) {
          return fileUri
        } else if (this.platform.is('android')) {
          // Modify fileUri format, may not always be necessary
          fileUri = 'file://' + fileUri;

          /* Using cordova-plugin-crop starts here */
          return Crop.crop(fileUri, { quality: 100 });
        }
      })
      .then((path) => {
        // path looks like 'file:///storage/emulated/0/Android/data/com.foo.bar/cache/1477008080626-cropped.jpg?1477008106566'
        console.log('Cropped Image Path!: ' + path);
        return path;
      })
  }

}

是否可以捕获图像并将其裁剪，然后将其上传到离子2中的firebase？
