import { Module } from '@nestjs/common';
import { AlicloudOssModule } from 'nestjs-alicloud-oss';

import { AppController } from './app.controller';
import { AppService } from './app.service';

@Module({
  controllers: [AppController],
  providers: [AppService],
  imports: [
    AlicloudOssModule.withConfig({
      options: {
        accessKeyId: '******',
        accessKeySecret: '******',
        region: '******', // the bucket data region location, doc demo used 'oss-cn-beijing'.
        bucket: '******', // the default bucket you want to access, doc demo used 'nest-alicloud-oss-demo'.
      },
    }),
  ],
})
export class AppModule {}

You may provide a default bucket name for the whole module, this will apply to all controllers withing this module. You can also provide (override) the bucket in the controller, for each route.

Examples

Store a file using the default bucket

import { Controller, Logger, Post, UploadedFile, UseInterceptors } from '@nestjs/common';
import { AlicloudOssFileInterceptor, UploadedFileMetadata } from 'nestjs-alicloud-oss';

@Controller()
export class AppController {
  @Post('upload')
  @UseInterceptors(AlicloudOssFileInterceptor('file'))
  UploadedFileUsingInterceptor(
    @UploadedFile()
    file: UploadedFileMetadata,
  ) {
    console.log(file.objectUrl);
    // http://nest-alicloud-oss-demo.oss-cn-beijing.aliyuncs.com/filename
  }
}

Store a file using a specific bucket and folder

import { Controller, Logger, Post, UploadedFile, UseInterceptors } from '@nestjs/common';
import { AlicloudOssFileInterceptor, UploadedFileMetadata } from 'nestjs-alicloud-oss';

@Controller()
export class AppController {
  @Post('upload2')
  @UseInterceptors(
    AlicloudOssFileInterceptor('file', null, {
      { folder: 'x/y/z', bucket: 'nest-alicloud-oss-demo2' },
    }),
  )
  UploadedFilesUsingInterceptor(
    @UploadedFile()
    file: UploadedFileMetadata,
  ) {
    console.log(file.objectUrl);
    // http://nest-alicloud-oss-demo2.oss-cn-beijing.aliyuncs.com/x/y/z/filename
  }
}

Store a file using a custom filename and custom bucket

import { Controller, Logger, Post, UploadedFile, UseInterceptors } from '@nestjs/common';
import { FileInterceptor } from '@nestjs/platform-express';
import { AlicloudOssService, UploadedFileMetadata } from 'nestjs-alicloud-oss';

@Controller()
export class AppController {
  constructor(private readonly ossService: AlicloudOssService) {}

  @Post('upload3')
  @UseInterceptors(FileInterceptor('file'))
  async UploadedFilesUsingService(
    @UploadedFile()
    file: UploadedFileMetadata,
  ) {
    file = {
      ...file,
      customName: 'customFilename.txt',
      folder: 'a/b/c',
      bucket: 'nest-alicloud-oss-demo3'
    };
    const url = await this.ossService.upload(file);

    console.log(url)
    // http://nest-alicloud-oss-demo3.oss-cn-beijing.aliyuncs.com/a/b/c/customFilename.txt

    console.log(file.objectUrl);
