NestJS/ExpressJs 参数过多

Question

我正在尝试将文件发送到 NestJS 控制器，但一直收到 too many parameters 异常。我已经安装 bodyParser 并更新了请求大小限制以绕过 request too large 异常。

main.ts:

import { NestFactory } from "@nestjs/core";
import { ApplicationModule } from "./app/app.module";
import * as express from "express";
import * as bodyParser from "body-parser";

async function bootstrap() {
    const server = express();
    server.use(bodyParser({limit: '50mb'}));

    console.log(server);

    const app = await NestFactory.create(ApplicationModule, server);
    await app.listen(process.env.PORT || 3000);
}
bootstrap();

控制器：

import { Get, Controller, Query, Post, Request } from "@nestjs/common";
import { CloudVisionLogoService } from "./logos.component";

@Controller("logos")
export class LogoRecognitionController {
    public constructor(
        private readonly _logoRecognition: CloudVisionLogoService
    ) {
    }

    @Post()
    public async detectLogos(@Request() req) {
        console.log(req.files[0]);
        // return await this._logoRecognition.detectLogos(imageUri);
    }
}

Answer 1

以下内容来自 body-parser 文档：

This does not handle multipart bodies, due to their complex and typically large nature. For multipart bodies, you may be interested in the following modules:

busboy and connect-busboy

multiparty and connect-multiparty

formidable

multer

我建议你使用 multer 包，因为它很简单，而且很多用户都在使用它
