Question

我需要在loopback模型中保存base64图像。当我保存base64图像时，我收到错误消息。我尝试在下面添加的中间件更新，我之前在loopback2中完成了，对于这个项目我升级到loopback3并陷入了这个问题，任何帮助将不胜感激

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
}

我也尝试过在middleware.json中更新

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

Answer 1

在middleware.json文件中，找到或添加“parse”并输入此配置对象，如下所示：

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

Answer 2

我也遇到了这个问题，通过在 server/config.json 文件中添加两行来解决

df["result"] = [how_many(row["at"], df["recovery_date"][:idx]) for idx, row in df.iterrows()]

环回3上的PayloadTooLargeError
