问题描述
单独使用单个JSONPath表达式，是否可以执行某种"OR"或"||"操作员.例如，这两个JSONPath布尔表达式可用于检查日志JSON文件的严重性:
Using a single JSONPath expression alone, is it possible to do some kind of 'OR' or '||' operator. For example, these two JSONPath boolean expressions work to check the severity of a log JSON file:
$..log[?(@.severity == 'WARN')]
$..log[?(@.severity == 'Error')]
但是我想在逻辑上做类似的事情:
But I'd like to do something logically similar to:
$..log[?(@.severity == 'WARN' or @.severity == 'Error')] //this is not correct
有什么办法吗?
推荐答案
来自 JSONPath页面:
[，]-XPath中的联合运算符导致节点集的组合. JSONPath允许将备用名称或数组索引作为一组.
[,] - Union operator in XPath results in a combination of node sets. JSONPath allows alternate names or array indices as a set.
尝试
$..log[?(@.severity == 'WARN'), ?(@.severity == 'Error')]
似乎有一个未解决的问题用于逻辑AND和OR运算符，其中它们指出JSONPath 尚不支持.
Looks like there is an open issue for logical AND and OR operators in which they state that the operators are not yet supported by JSONPath.
