Question

我正在研究一个dialogflow POC，在其中尝试调用DialogFlow提供的 v2 API。尝试提供here的NodeJS代码示例时，出现以下错误

{ Error: EHOSTUNREACH undefined: Getting metadata from plugin failed with error: request to https://www.googleapis.com/oauth2/v4/token failed, reason: connect EHOSTUNREACH 0.0.38.172:80 - Local (192.168.0.103:51468)
    at Object.callErrorFromStatus (/Users/devuser/Development/workspaces/df-poc/node_modules/@grpc/grpc-js/build/src/call.js:30:26)
    at Http2CallStream.call.on (/Users/devuser/Development/workspaces/df-poc/node_modules/@grpc/grpc-js/build/src/client.js:96:33)

    at process._tickCallback (internal/process/next_tick.js:61:11)
  code: 'EHOSTUNREACH',
  details:
   'Getting metadata from plugin failed with error: request to https://www.googleapis.com/oauth2/v4/token failed, reason: connect EHOSTUNREACH 0.0.38.172:80 - Local (192.168.0.103:51468)',
  metadata: Metadata { internalRepr: Map {}, options: {} } }

我已导入GOOGLE_APPLICATION_CREDENTIALS，并将环境变量指向凭据。如果我尝试使用Authorization标头的REST API路由，则调用工作正常。请让我知道这里是否缺少某些东西。

这意味着EHOST（您请求的文件的远程主机）不可访问。它们已关闭，或者由于某些其他限制（例如位置），您的计算机无法访问它们，可以使用VPN来解决。
