我正在尝试将文件发送到 NestJS 控制器,但不断收到too many parameters异常。我已经安装bodyParser并更新了请求大小限制以解决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);
    }
}

邮递员请求(未显示,图像的二进制附件):

POST /logos HTTP/1.1
Host: localhost:3000
Content-Type: application/x-www-form-urlencoded
Cache-Control: no-cache
Postman-Token: c95da069-c602-58a9-1e05-36456a527f02

以下来自body-parser文档:

这不处理多部分实体,因为它们复杂且通常很大。对于多部分正文,您可能对以下模块感兴趣:

busboy 和 connect-busboy

多方和连接多方

我建议你使用multer包,因为它很简单而且很多用户都使用它
