NestJs 将 Morgan 和 Nest-Winston 的输出合并到一个文件中

如何解决NestJs 将 Morgan 和 Nest-Winston 的输出合并到一个文件中

我正在尝试使用 nest - winston 在一个文件中记录所有快速日志和未处理的异常。关注以下文章::

1. https://www.npmjs.com/package/nest-winston
2. https://www.section.io/engineering-education/logging-with-winston/
3. Node.js - logging / Use morgan and winston

我研究了一下，发现应该使用morgan来记录express日志。

#include "std_lib_facilities.h"

int main()
{
    cout << "Enter a series of double values,which represent the distance between two cities\n"
            "(followed by '|' or a another non double/integer character):\n";

    vector<double> distances; // city distances
    for (double distance; cin >> distance; ) // read into distance
        distances.push_back(distance);  // put distance into vector


    // compute total distance:
    double sum {0.0};
    for (double distance : distances)
        sum += distance;
    cout << "Total distance: " << sum << '\n';

    // compute smallest and largest distance:
    sort(distances); // sort distances
    cout << "Smallest distance: " << distances[0] << '\n'
         << "Largest distance: " << distances[distances.size()-1] << '\n';
         
         
    cout << "The mean distance between two cities is: " << sum/distances.size() << '\n';
    keep_window_open();
    return 0;
}

Winston 正确地将数据记录到文件中。

const winston = require("winston");
const morgan = require("morgan");

async function bootstrap() {
  const appOptions = {
    cors: true,logger: WinstonModule.createLogger({
      transports: [
        new winston.transports.Console({}),// ==> 1
        new winston.transports.File({
          filename:
            "logs/Combined-" + new Date(Date.now()).toDateString() + ".log",level: "info",handleExceptions: true,}),new winston.transports.File({
          filename:
            "logs/Errors-" + new Date(Date.now()).toDateString() + ".log",level: "error",],format: winston.format.combine(
        winston.format.timestamp({
          format: "MMM-DD-YYYY HH:mm:ss",winston.format.printf(
          (error) => `${error.level}: ${[error.timestamp]}: ${error.message}`
        )
      ),};
  const app = await NestFactory.create(ApplicationModule,appOptions);
  app.setGlobalPrefix("api");
  
  app.use(morgan("combined",{ stream: winston.stream.write }));  // ==> 2

  const options = new DocumentBuilder()
    .setTitle("xx")
    .setDescription("xx")
    .setVersion("1.0")
    .setBasePath("api")
    .addBearerAuth()
    .build();
  const document = SwaggerModule.createDocument(app,options);
  SwaggerModule.setup("/docs",app,document);

  await app.listen(3000);
}
bootstrap();

现在我想记录我插入摩根的所有快速日志，如代码所示（第 2 点）。它记录到控制台，但不记录到文件。 但是如果我注释掉第 1 点，即登录到控制台。项目没有启动。它在低于 2 行后卡住。我等了 15 分钟，但没有进展。
