Question

我正在使用nodeJS，express，swagger-tools来获取来自我的Heroku dyno中的/ docs的Swagger API文档。在本地，这是有效的，但在Heroku上，端口没有收听。

app[web.1]: info: Swagger-ui is available on localhost:5765/docs
heroku[web.1]: State changed from crashed to starting
heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch
heroku[web.1]: Stopping process with SIGKILL
heroku[web.1]: Process exited with status 137

在代码上，我有Heroku预定的端口。

var listen_addr = 'localhost';
var listen_port = process.env.PORT || 8080;

var swaggerDoc = require(options.swaggerUi);
swaggerDoc.host = listen_addr +":" + listen_port;    // making sure of add

swaggerTools.initializeMiddleware(swaggerDoc, function (middleware) {

  app.use(middleware.swaggerMetadata());
  app.use(middleware.swaggerValidator());           
  app.use(middleware.swaggerUi() );             
  app.use(middleware.swaggerRouter(options) );

  app.listen(listen_port, listen_addr) {      
    winston.info('Server is listening on %s:%d', listen, port);
    winston.info('Swagger-ui is available on %s:%d/docs', listen, port);
  });
});

更新：问题似乎是通过将app.listen更改为app.listen来解决的（process.env.PORT || 3000，function（）

在Heroku上运行Swagger：端口问题？
