我需要發送包含 base64 字串的請求，它太大（可能，大約 2 mb）。
但是服務器拋出下一個例外，如何避免這個錯誤：

我的 main.ts 包括：
async function bootstrap() {
const app = await NestFactory.create<NestExpressApplication>(AppModule);
// app.enableCors({
// origin: '*',
// });
const config = new DocumentBuilder()
.setTitle('API client gateway')
.setDescription('API client gateway full documentation')
.setVersion('v0.0.1')
.addTag('')
.addBearerAuth(
{
type: 'http',
scheme: 'bearer',
bearerFormat: 'JWT',
name: 'JWT',
description: 'Enter JWT token',
in: 'header',
},
'jwt-token',
)
.build();
const document = SwaggerModule.createDocument(app, config);
SwaggerModule.setup('/api/docs', app, document);
await app.init();
app.use(express.json({limit: "50mb"})) //For JSON requests
app.use(express.urlencoded({
limit: "50mb",
extended: false
}));
await app.listen(AppConfig.Port);
}
bootstrap();
uj5u.com熱心網友回復：
在您的main.ts檔案（最有可能的bootstrap()方法）中獲取 Express App 的實體并設定 JSON 決議器的限制：
import { json } from 'body-parser';
async function bootstrap() {
const app = await NestFactory.create<NestExpressApplication>(AppModule,
{ bodyParser: false });
app.use(json({ limit: '5mb' }));
...
}
編輯：如果您通過代理（例如 nginx）訪問應用程式，請確保也有相同的限制。
