Question

我目前正在使用带有Express的bodyParser来接受JSON请求。每当我传入一个错误形成的JSON对象时，它都会通过端点返回一个讨厌的错误，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)
    at /Users/ddibiase-mbp/Documents/Projects/theride_api/node_modules/body-parser/lib/read.js:108:18
    at done (/Users/ddibiase-mbp/Documents/Projects/theride_api/node_modules/body-parser/node_modules/raw-body/index.js:239:14)

我想知道如何能够完全抑制错误或修补错误。我已经调查了错误，但找不到任何具体的修补建议。

通过Express：

声明error handler是很常见的

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

这也会捕获像body-parser这样的中间件中抛出的错误。
