快速入门

安装

你可以使用我们的 AI 辅助设置来安装插件。使用以下命令将 Capgo skills 添加到你的 AI 工具中：

npx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins

然后使用以下 prompt：

Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/capacitor-uploader` plugin in my project.

如果你更想手动设置，请运行以下命令安装插件，并按照下方各平台的说明操作：

bun add @capgo/capacitor-uploader
bunx cap sync

导入

import { Uploader } from '@capgo/capacitor-uploader';

快速入门

开始上传并订阅 events，同时追踪返回的上传 id.

import { Uploader } from '@capgo/capacitor-uploader';

let uploadId = '';

const listener = await Uploader.addListener('events', async (event) => {
  if (event.id !== uploadId) return;

  if (event.name === 'uploading') {
    console.log(event.payload.percent);
  }

  if (event.name === 'completed' || event.name === 'failed') {
    if (event.eventId) {
      await Uploader.acknowledgeEvent({ eventId: event.eventId });
    }
    await listener.remove();
  }
});

const { id } = await Uploader.startUpload({
  filePath: 'file:///data/user/0/.../scan.jpg',
  serverUrl: 'https://api.example.com/v1/assets',
  method: 'POST',
  headers: { Authorization: 'Bearer token' },
  maxRetries: 3,
});
uploadId = id;

示例：S3 预签名 PUT

PUT 上传仅支持单个文件。请将预签名 URL 作为 serverUrl 并设置 method: 'PUT'.

await Uploader.startUpload({
  filePath: capturedUri,
  serverUrl: presignedUrl,
  method: 'PUT',
  headers: { 'Content-Type': 'image/jpeg' },
});

示例：包含额外字段的 multipart 表单

await Uploader.uploadMultipart({
  url: 'https://api.example.com/upload',
  filePath: localPath,
  fieldName: 'file',
  fields: { userId: '42', kind: 'receipt' },
  headers: { Authorization: 'Bearer token' },
});

常见坑点

• 多个文件：使用 files 数组来 startUpload 进行单个 multipart 请求。 PUT 无法发送多个 body。
• Web 后台：如果用户关闭标签页，上传将会停止。如果需要在应用进入后台时仍能完成上传，请使用 native 平台。
• 取消: 调用 removeUpload({ id }) 配合来自 startUpload.
• 进度：务必在开始前绑定 events 监听器，否则可能会错过早期的进度信息。

API 概览

startUpload

开始向服务器上传文件。

即使应用被关闭或进入后台，上传仍会在后台继续进行。 通过监听上传事件来跟踪进度、完成状态或失败情况。

import { Uploader } from '@capgo/capacitor-uploader';

const { id } = await Uploader.startUpload({
  filePath: 'file:///path/to/file.jpg',
  serverUrl: 'https://example.com/upload',
  headers: {
    'Authorization': 'Bearer token'
  },
  method: 'POST',
  uploadType: 'multipart',
  fileField: 'photo'
});
console.log('Upload started with ID:', id);

removeUpload

取消并移除正在进行的上传。

如果上传正在进行，此操作将停止上传并清理资源。

import { Uploader } from '@capgo/capacitor-uploader';

await Uploader.removeUpload({ id: 'upload-123' });

类型参考

uploadOption

文件上传的配置选项。

export interface uploadOption {
  /**
   * The local file path of the file to upload.
   * Can be a file:// URL or an absolute path.
   *
   * @since 0.0.1

  serverUrl: string;

  /**
   * The title of the upload notification shown to the user.
   * Android only.
   *
   * @default 'Uploading'
   * @since 0.0.1
   */
  notificationTitle?: string;

  /**
   * HTTP headers to send with the upload request.
   * Useful for authentication tokens, content types, etc.
   *
   * @since 0.0.1
   * @example

  headers: {

   *
   * @default 'POST'
   * @since 0.0.1
   */
  method?: 'PUT' | 'POST';

  /**
   * The MIME type of the file being uploaded.
   * If not specified, the plugin will attempt to determine it automatically.
   *
   * @since 0.0.1
   * @example 'image/jpeg', 'application/pdf', 'video/mp4'
   */
  mimeType?: string;

  /**

   * These will be included as form data in multipart uploads.

   */
  parameters?: { [key: string]: string };

  /**
   * The maximum number of times to retry the upload if it fails.
   *
   * @since 0.0.1
   * @default 0
   */
  maxRetries?: number;

  /**
   * The type of upload to perform.
   * - 'binary': Uploads the file as raw binary data in the request body
   * - 'multipart': Uploads the file as multipart/form-data
   *

   * @since 0.0.2
   */
  uploadType?: 'binary' | 'multipart';

   * Only used when uploadType is 'multipart'.
   *
   * @default 'file'

   */
  fileField?: string;
}

UploadEvent

上传生命周期中触发的事件。

export interface UploadEvent {
  /**
   * The current status of the upload.
   * - 'uploading': Upload is in progress
   * - 'completed': Upload finished successfully
   * - 'failed': Upload encountered an error
   *
   * @since 0.0.1
   */
  name: 'uploading' | 'completed' | 'failed';

  /**
   * Additional data about the upload event.
   *
   * @since 0.0.1
   */
  payload: {
    /**
     * Upload progress percentage from 0 to 100.
     * Only present during 'uploading' events.
     *
     * @since 0.0.1
     */
    percent?: number;

    /**
     * Error message if the upload failed.
     * Only present during 'failed' events.
     *
     * @since 0.0.1
     */
    error?: string;

    /**
     * HTTP status code returned by the server.
     * Present during 'completed' and 'failed' events.
     *
     * @since 0.0.1
     */
    statusCode?: number;
  };

  /**
   * Unique identifier for this upload task.
   *
   * @since 0.0.1
   */
  id: string;
}
