Question

如何从go: github.com/coreos/go-oidc@v2@v2.0.0+incompatible: invalid github.com/ import path "github.com/coreos/go-oidc@v2" go: error loading module requirements中检索"msg"对象？

整个数组的输出如下：errors.array()

我尝试用[{"value":"abc","msg":"Your email is not valid","param":"email","location":"body"}]指定"msg"对象，但没有返回任何内容。

errors.array()[1]

我的静态文件中输出错误：

  router.post("/signup",
  [
    check('email', 'Your email is not valid').not().isEmpty().isEmail().normalizeEmail(),
    check('password', 'Your password must be at least 5 characters').not().isEmpty().isLength({min: 5})
  ],
  function (req, res, next) {
    const errors = validationResult(req);

    if (!errors.isEmpty()) {
      res.render("user/signup", {
        hasErrors: JSON.stringify(errors.array()[1])
      });
    } else {
      //...
    }
  });

如果要访问错误，可以使用.array()或.mapped()。否则，您可以使用doc中显示的.formatWith：

app.post('/create-user', yourValidationChains, (req, res) => {
  // errors will be like [{ myLocation: 'body' }, { myLocation: 'query' }], etc
  const errors = myValidationResult(req).array();
});

或者， formatWith ：

app.post('/create-user', yourValidationChains, (req, res, next) => {
  const errorFormatter = ({ location, msg, param, value, nestedErrors }) => {
    // Build your resulting errors however you want! String, object, whatever - it works!
    return `${location}[${param}]: ${msg}`;
  };
  const result = validationResult(req).formatWith(errorFormatter);
  if (!result.isEmpty()) {
    // Response will contain something like
    // { errors: [ "body[password]: must be at least 10 chars long" ] }
    return res.json({ errors: result.array() });
  }

  // Handle your request as if no errors happened
});

如何从express-validator数组中检索特定项目？
