PayloadTooLargeError on loopback 3

Question

我需要在回送模型中保存base64圖像。當我保存base64圖像時，我收到一個錯誤消息。我曾嘗試在中間件下同補充更新，我已經在了環回做之前，這個項目我升級到Loopback3接口，並陷入了這個問題，任何幫助將非常感激

server.js

let loopback = require('loopback'); 
let boot = require('loopback-boot'); 
let bodyParser = require("body-parser"); 
let app = module.exports = loopback(); 

app.use(bodyParser.urlencoded({extended: true,limit:10485760})); 

config.json

{ 
    "restApiRoot": "/api", 
    "host": "0.0.0.0", 
    "port": 3000, 
    "remoting": { 
    "context": false, 
    "rest": { 
     "handleErrors": false, 
     "normalizeHttpPath": false, 
     "xml": false 
    }, 
    "json": { 
     "strict": false, 
     "limit": 10485760 
    }, 
    "urlencoded": { 
     "extended": true, 
     "limit": 10485760 
    }, 
    "cors": false 
    }, 
    "legacyExplorer": false, 
    "logoutSessionsOnSensitiveChanges": true 
} 

我也試圖在middleware.json

"parse": { 
    "body-parser#json": { 
     "limit": "52428800" 
    }, 
    "body-parser#urlencoded": { 
     "params": { 
     "extended": true 
     }, 
     "limit": "52428800" 
    } 
    }, 

Answer 1

更新裏面的middleware.json文件中，找到或添加「解析」，並輸入類似下面的配置對象：

"parse": { 
    "body-parser#json": { "params" : { "limit" : "50mb"} }, 
    "body-parser#urlencoded": {"params": { "limit" : "50mb", "extended": true }} 
    },
