jsonpath

jq

说明

curl命令使用jq，结合jsopath,可以对响应的json数据做格式化和过滤处理 最简单的jq程序是表达式 ‘.’ ，表示响应的数据 更多信息，查看官方文档https://stedolan.github.io/jq/

示例

1.不使用jq时的响应结果

curl 'https://api.github.com/repos/stedolan/jq/commits?per_page=5'

2.使用jq格式化响应结果

curl 'https://api.github.com/repos/stedolan/jq/commits?per_page=5' | jq '.'

3.获取响应列表中的第一个对象

curl 'https://api.github.com/repos/stedolan/jq/commits?per_page=5' | jq '.[0]'

4.获取响应列表中的第一个对象中的具体信息,并以json格式显示(匹配信息的路径使用jsonpath)

jq '.[0] | {message: .commit.message, name: .commit.committer.name}'
