快速：錯誤在readStream

當客戶端應用程序嘗試發送帶有base64編碼圖像的POST請求時，服務器正在拋出此錯誤。快速：錯誤在readStream

我已經doublechecked請求正文：base64字符串沒有格式錯誤。如果應用在沒有base64部件的情況下發送相同請求，則一切正常。

server.js：

import http from 'http' 
import express from 'express' 
import cors from 'cors' 
import morgan from 'morgan' 
import bodyParser from 'body-parser' 
import api from './api' 
import config from './config' 

let app = express() 
app.server = http.createServer(app) 

// logger 
app.use(morgan('dev')) 

// 3rd party middleware 
app.use(cors({ 
    exposedHeaders: config.corsHeaders 
})) 

app.use(bodyParser.json({ 
    limit : config.bodyLimit 
})) 

app.use(express.static("./assets")) 

// api router 
app.use('/api', api) 

app.server.listen(process.env.PORT || config.port) 

console.log(`Started on port ${app.server.address().port}`) 

export default app

api.js

import { Router } from 'express'; 
const router = Router(); 

router.post('/createPost', require('./methods/createPost').default) 

export default router

FWIW我有完全相同的問題。如果我通過一個小的測試體發佈請求，它會成功通過，但如果我的請求體較大（音頻 - 視頻數據），則會顯示上述錯誤。 – TonyM

我認爲這是與此相同的問題：

Error: request entity too large

身體解析器的限制設置得太低（默認是100k）。

以我爲例，我發現，設定限制：如在鏈接的解決方案描述的「50MB」上面固定我的問題：

app.use(bodyParser.json({limit: '50mb'}));

它看起來像你的極限在配置設定。
