其他人有同样的问题吗?.

Is anyone else having the same problem?.

推荐答案

最近 Google 关闭了 v1 API.V2 API 现在需要一个密钥，而流式 v2 API 限制为每天 50 个请求.您可以按照此处的说明获取密钥:

Recently Google closed v1 API. V2 API now requires a key and streaming v2 API is limited to 50 requests per day. You can get a key as described here:

http://www.chromium.org/developers/how-tos/api-keys

但是不保证无限使用.
