如何使用 express-winston 排除 cookie？

Question

阅读express-winston README 似乎很容易从记录的行中删除 headers：我们可以简单地对requestWhitelist 选项进行操作，但这将禁止记录所有标头。

有没有办法只禁用 cookie 标头？

Answer 1

据我所知，您可以创建一个自定义过滤器，例如：

function customRequestFilter(req, propName) {
  if(propName !== "headers") return req[propName];

  const { cookie, ...rest } = req.headers;

  return rest;
}

你的温斯顿选项应该是这样的：

expressWinston.logger({
    transports: [new winston.transports.Console()],
    // requestWhitelist: ['headers'],
    requestFilter: customRequestFilter,
    format: winston.format.combine(
      winston.format.colorize(),
      winston.format.json()
    ),
    meta: true, // optional: control whether you want to log the meta data about the request (default to true)
    msg: "HTTP {{req.method}} {{req.url}}", // optional: customize the default logging message. E.g. "{{res.statusCode}} {{req.method}} {{res.responseTime}}ms {{req.url}}"
    expressFormat: true, // Use the default Express/morgan request formatting. Enabling this will override any msg if true. Will only output colors with colorize set to true
    colorize: false, // Color the text and status code, using the Express/morgan color palette (text: gray, status: default green, 3XX cyan, 4XX yellow, 5XX red).
    ignoreRoute: function (req, res) {
      return false;
    }, // optional: allows to skip some log messages based on request and/or response
  })

希望对你有帮助！ 干杯。
