如何在feathersjs中解决请求实体太大的错误？

Question

我在羽毛服务中上传csv文件且文件大小为203kb，它会抛出一个错误请求实体太大的错误，就像这样。

错误：

我正在写这样的中间件代码，但我无法解决

app.js：

{
    "name": "GeneralError",
    "message": "request entity too large",
    "code": 500,
    "className": "general-error",
    "data": {},
    "errors": {}
}

location.service.js：

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

location.hooks.js：

// Initializes the `location` service on path `/location`
const createService = require('feathers-mongoose');
const createModel = require('../../models/location.model');
const hooks = require('./location.hooks');
const filters = require('./location.filters');
const multer = require('multer');
const multipartMiddleware = multer();

module.exports = function () {
  const app = this;
  const Model = createModel(app);
  const paginate = app.get('paginate');

  const options = {
    name: 'location',
    Model,
    paginate
  };

  // Initialize our service with any options it requires
  app.use('/location',
      multipartMiddleware.single('uri'),
        (req, res, next) => {
            req.feathers.file = req.file;
            next();
        },
    createService(options)
  );

  // Get our initialized service so that we can register hooks and filters
  const service = app.service('location');

  service.hooks(hooks);

  if (service.filter) {
    service.filter(filters);
  }
};

我使用邮递员上传csv文件

Answer 1

我在app.js文件中有更改代码

<强>之前：

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

<强>后：

app.use(bodyParser.json({limit: '100mb'}));
app.use(bodyParser.urlencoded({
  limit: '100mb',
  extended: true
}));

Answer 2

我在我的Node / express应用程序中遇到了同样的问题，我使用了它，它解决了我的问题，希望它也适合你：

app.use(bodyParser.json({limit:1024102420, type:'application/json'}));

我使用了数字格式的限制，它指定了字节数

Answer 3

打开app.js文件并替换以下几行

app.use(express.json());
app.use(express.urlencoded({ extended: true }));

使用

app.use(express.json({ limit: "50mb" }));
app.use(express.urlencoded({ limit: "50mb", extended: true }));
