使用typegraphql上传文件(Apollo Server)

import { ApolloServer } from 'apollo-server';

const server = new ApolloServer({
  uploads: false,
  // 其他配置项...
});

import { InputType, Field } from 'type-graphql';
import { GraphQLUpload } from 'graphql-upload';

@InputType()
class FileUploadInput {
  @Field(() => GraphQLUpload)
  file: Promise<File>;
}

import { Resolver, Mutation, Arg } from 'type-graphql';

@Resolver()
class FileResolver {
  @Mutation(() => String)
  async uploadFile(@Arg('file', () => FileUploadInput) file: FileUploadInput): Promise<string> {
    const { createReadStream, filename, mimetype } = await file.file;
    // 处理文件上传逻辑，例如保存文件到本地或云存储

    return filename;
  }
}

import { buildSchema } from 'type-graphql';

async function bootstrap() {
  const schema = await buildSchema({
    resolvers: [FileResolver], // 添加文件上传的 resolver
  });

  const server = new ApolloServer({
    schema,
    uploads: false, // 禁用文件上传处理器
  });

  server.listen().then(({ url }) => {
    console.log(`Server ready at ${url}`);
  });
}

bootstrap();
