curl mydb/_changes?feed=大约20秒后连续断开连接

Question

基于API引用，连续式参数将保持连接打开。但是，下面的curl命令在大约20秒后返回，根据API引用，这似乎不正确。有人能解释一下吗？谢谢。

curl https://cloudant-URL-bluemix.cloudant.com/mydb/_changes?feed=continuous --http1.1

返回：

Answer 1

尝试：

curl 'https://cloudant-URL-bluemix.cloudant.com/mydb/_changes?feed=continuous&heatbeat=1000'

如果没有任何变化要报告的话，可能是超时了。看见
