Question

我在docker容器中运行以下命令：

curl 'https://demo.cachethq.io/API/v1/components?name=Blog' | tac | tac | jq '.'

但我得到null输出（在curl进度条之后）没有最终的jq命令运行会给出正确的json。任何帮助，将不胜感激（tac用于停止在jq之前结束的卷曲输出）

Answer 1

这是一个微不足道的错误。

请更改网址：

curl 'https://demo.cachethq.io/API/v1/components?name=Blog' | tac | tac | jq '.'

收件人：

curl 'https://demo.cachethq.io/api/v1/components?name=Blog' | tac | tac | jq '.'

输出

jq从curl返回null
