Question

我正在尝试连接Cygnus和STH。我在容器docker中有一个Cygnus实例，在VM中有一个STH实例。

当我向天鹅座发送通知时，可以在fiware-cygnus/cygnus-ngsi/resources/ngsi-examples/notification-json-simple.sh处找到，它会显示以下错误：

注意：我更换了STH IP以发布问题

STH没有发布任何内容。

在我的agent.conf（cygnus conf）中我有这个：

我的STH配置是：

var config = {};

// STH server configuration
//--------------------------
config.server = {

  host: '10.0.2.15',

  port: '8666',


  defaultService: 'testservice',


  defaultServicePath: '/testservicepath',


  filterOutEmpty: 'true',

  aggregationBy: ['day', 'hour', 'minute'],

  temporalDir: 'temp'
};

// Database configuration
//------------------------
config.database = {

  dataModel: 'collection-per-entity',
 user: '',

  password: '',

  URI: 'localhost:27017',

  replicaSet: '',

  prefix: 'sth_',


  collectionPrefix: 'sth_',

  poolSize: '5',


  shouldStore: 'both',
  truncation: {


    expireAfterSeconds: '0',
    size: '0',

    max: '0'
  },

  ignoreBlankSpaces: 'true',
  nameMapping: {

    enabled: 'false',

    configFile: './name-mapping.json'
  },

  nameEncoding: 'false'
};

// Logging configuration
//------------------------
config.logging = {
  level: 'info',
  NODE_ENV variable is set to 'development'.

  format: 'pipe',


  proofOfLifeInterval: '60'
};

module.exports = config;

我找到了解决这个问题的方法：我刚刚编辑了/etc/mongod.conf，并注释了bindip=127.0.0.1来监听所有接口。
