我目前正在使用带有 Express 的 bodyParser 来接受 JSON 请求。每当我传入格式不正确的 JSON 对象时，它都会通过端点返回一个令人讨厌的错误，并将其记录到控制台。以下是错误：

SyntaxError: Unexpected string
    at Object.parse (native)
    at parse (/Users/ddibiase-mbp/Documents/Projects/theride_api/node_modules/body-parser/lib/types/json.js:88:17)

我想知道如何抑制错误或完全修补它。我已经调查了该错误，但找不到任何修补它的具体建议。

使用 Express声明错误处理程序很常见：

app.use(function(err, req, res, next) {
  ...
  return res.sendStatus(500);
});

这也将捕获中间件中抛出的错误，例如body-parser.
