Question

我在后端使用loopback。我收到此错误

<StackLayout Orientation="Vertical" BackgroundColor="Black" Padding="4" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
    <StackLayout Orientation="Vertical" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" BackgroundColor="White" Padding="4">
        <!--Put your editor here-->
    </StackLayout>
</StackLayout>

我已经搜索过stackoverflow，但我没有找到答案。基本上，我试图使用身体解析器。我经历了一个stackoverflow线程并实现了它的解决方案。我成功地使用了body-parser。所以，这个错误已经解决了。但是，现在这个错误让我很难过。

server.js文件

在middleware.json中，我也更新了parse属性

'use strict';

var loopback = require('loopback');
var boot = require('loopback-boot');
var bodyParser = require('body-parser');
var multer = require('multer');

var app = module.exports = loopback();

//code for body parsing
app.use(bodyParser.json()); // for parsing application/json
app.use(bodyParser.urlencoded({ extended: true })); // for parsing application/x-www-form-urlencoded
//app.use(multer()); // for parsing multipart/form-data

//code for body parsing ends

app.start = function() {
  // start the web server
  return app.listen(function() {
    app.emit('started');
    var baseUrl = app.get('url').replace(/\/$/, '');
    console.log('Web server listening at: %s', baseUrl);
    if (app.get('loopback-component-explorer')) {
      var explorerPath = app.get('loopback-component-explorer').mountPath;
      console.log('Browse your REST API at %s%s', baseUrl, explorerPath);
    }
  });
};

// Bootstrap the application, configure models, datasources and middleware.
// Sub-apps like REST API are mounted via boot scripts.
boot(app, __dirname, function(err) {
  if (err) throw err;

  // start the server if `$ node server.js`
  if (require.main === module)
    app.start();
});

出于某种原因，该错误已经消失。不确定，可能会再来。但现在，这是错误，我看到了

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

Answer 1

检查您的过滤器或网址是否有空格（例如％20），或者过滤器或网址是否有问题。

Answer 2

环回3使array和object之间有所不同。您必须检查您的数据类型。有关更多信息，请参见https://github.com/strongloop/strong-remoting/issues/360。

Answer 3

我遇到了同样的错误，但在我的情况下，这是由于模型属性数据长度造成的。该属性是类型对象和一个小数据长度，这导致了我的 sql 模型表中的错误记录。我必须手动删除那些错误记录并增加该属性的 dataLength 。重启应用

环回错误 - 值不是对象
