PayloadTooLargeError sur le bouclage 3

Question

Je dois sauvegarder l'image base64 dans le modèle de bouclage. Quand je sauve l'image de base64 j'obtiens une erreur indiquant. J'ai essayé la mise à jour du middleware même ajouté ci-dessous, je l'ai fait auparavant dans loopback2, pour ce projet, je surclassé loopback3 et est resté coincé dans ce problème, toute aide sera très appréciée

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 
} 

J'ai aussi essayé de mettre à jour dans middleware.json

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

Answer 1

A l'intérieur du fichier middleware.json, recherchez ou ajoutez "analyser" et entrez cet objet config comme ce qui suit :

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