## Methods

### apollo# ```remoteConfigServiceFromCache(config)```
```
  const config = {
    configServerUrl: 'http://example.com',
    appId: '<appId>',
    clusterName: 'default',
    namespaceName: [ 'namespaceName1', 'namespaceName2' ],
    // clientIp: '',
    };
  const result = await apollo.remoteConfigServiceFromCache(config);
```
  >**NOTE:** 通过带缓存的Http接口从Apollo读取配置，详情请参考[Apollo开放平台](https://github.com/ctripcorp/apollo/wiki/%E5%85%B6%E5%AE%83%E8%AF%AD%E8%A8%80%E5%AE%A2%E6%88%B7%E7%AB%AF%E6%8E%A5%E5%85%A5%E6%8C%87%E5%8D%97#12-%E9%80%9A%E8%BF%87%E5%B8%A6%E7%BC%93%E5%AD%98%E7%9A%84http%E6%8E%A5%E5%8F%A3%E4%BB%8Eapollo%E8%AF%BB%E5%8F%96%E9%85%8D%E7%BD%AE).
### apollo# ```remoteConfigServiceSikpCache(config)```
```
  const config = {
    configServerUrl: 'http://example.com',
    appId: '<appId>',
    clusterName: 'default',
    namespaceName: [ 'namespaceName1', 'namespaceName2' ],
    // clientIp: '',
    };
  const result = await apollo.remoteConfigServiceSikpCache(config);
```
  >**NOTE:** 通过不带缓存的Http接口从Apollo读取配置，详情请参考[Apollo开放平台](https://github.com/ctripcorp/apollo/wiki/%E5%85%B6%E5%AE%83%E8%AF%AD%E8%A8%80%E5%AE%A2%E6%88%B7%E7%AB%AF%E6%8E%A5%E5%85%A5%E6%8C%87%E5%8D%97#13-%E9%80%9A%E8%BF%87%E4%B8%8D%E5%B8%A6%E7%BC%93%E5%AD%98%E7%9A%84http%E6%8E%A5%E5%8F%A3%E4%BB%8Eapollo%E8%AF%BB%E5%8F%96%E9%85%8D%E7%BD%AE).
### apollo# ```remoteConfigService(config)```
```
  const config = {
      configServerUrl: 'http://example.com',
      appId: '<appId>',
      clusterName: 'default',
      namespaceName: '',
      apolloEnv: 'dev',

  >**NOTE:** 读取携程Apollo配置，调用第三方应用接入Apollo开放平台， 详情请参考[Apollo开放平台](https://github.com/ctripcorp/apollo/wiki/Apollo%E5%BC%80%E6%94%BE%E5%B9%B3%E5%8F%B0).
### apollo# ```createEnvFile(envConfig)```
```
  const envConfig = {
      mongoose: 'mongo://127.0.0.1:27017',
      appId: '<appId>',
    };
  apollo.createEnvFile(envConfig);
```
>**NOTE:** 生成环境变量文件，常用于docker化项目，详细请参考[example](https://github.com/Quinton/node-apollo/tree/master/example).
### apollo# ```setEnv()```
```
apollo.setEnv();
```
>**NOTE:** 注入环境变量到process.env, 详情请参考[dotenv](https://github.com/motdotla/dotenv#usage).
