node.js - 为什么 Winston 记录器会删除错误详细信息

Question

我试图记录 axios 错误，所以我定义了一个自定义错误并使用 Winston.error 记录。但是，没有显示响应详细信息。奇怪的是，console.log 打印了所有细节。

使用console.log，我得到了这个。

     response:

        data: 'Thank you for this dump. I hope you have a lovely day!' },
     isAxiosError: true,
     toJSON: [Function] } }

至于 Winston.error()，我得到了这个

{"name":"MyError","myerror":{"message":"Request failed with status code 500","name":"Error","stack":"Error: Request failed with status code 500\n    at createError (/Users/woonggeunjang/dev/onda-cms/node_modules/axios/lib/core/createError.js:16:15)\n    at settle (/Users/woonggeunjang/dev/onda-cms/node_modules/axios/lib/core/settle.js:17:12)\n    at IncomingMessage.handleStreamEnd (/Users/woonggeunjang/dev/onda-cms/node_modules/axios/lib/adapters/http.js:236:11)\n    at IncomingMessage.emit (events.js:203:15)\n    at IncomingMessage.EventEmitter.emit (domain.js:448:20)\n    at endReadableNT (_stream_readable.js:1145:12)\n    at process._tickCallback (internal/process/next_tick.js:63:19)","config":{"url":"https://ptsv2.com/t/gcnad-1585724700/post","method":"post","data":"hmm","headers":{"Accept":"application/json, text/plain, */*","Content-Type":"application/x-www-form-urlencoded","User-Agent":"axios/0.19.2","Content-Length":3},"transformRequest":[null],"transformResponse":[null],"timeout":0,"xsrfCookieName":"XSRF-TOKEN","xsrfHeaderName":"X-XSRF-TOKEN","maxContentLength":-1}},"level":"error","message":"mm","stack":"MyError: \n    at new MyError (/Users/woonggeunjang/dev/onda-cms/src/axios-test.ts:16:15)\n    at /Users/woonggeunjang/dev/onda-cms/src/axios-test.ts:29:15\n    at Generator.throw (<anonymous>)\n    at rejected (/Users/woonggeunjang/dev/onda-cms/src/axios-test.ts:6:65)\n    at process._tickCallback (internal/process/next_tick.js:68:7)","timestamp":"2020-04-01T12:43:45.530Z"}

这是我的代码

export default class MyError extends Error {

myerror: string;

constructor(error: string) {
    super();
    Object.setPrototypeOf(this, new.target.prototype);
    this.name = 'MyError';
    this.myerror = error;
    Error.captureStackTrace(this);
}
}

async function testPost () {

let res = null;
try {
    res = await axios.post('https://ptsv2.com/t/gcnad-1585724700/post', 'hmm');
} catch (error) {
    // throw new Error(error);
// console.log(error);
// Logger.error('hmm', error.stack);
    throw(new MyError(error));
}
}

testPost().catch(error => {
    // console.log(error);
    Logger.error('mm', error );
});

使用winston时似乎应用了一些格式。如果我设置 prettyPrint 格式，则会显示错误详细信息。

更新这是我的温斯顿配置

const consoleTransport = new transports.Console();
const Logger = createLogger({
    transports: [consoleTransport],
    format: format.combine(
        format.timestamp(),
        format.json(),
    ),
});

提前致谢。
