我有一个字典列表（基本上是端点的 JSON 响应）

我需要解析这 16000 行 json 对象并过滤符合条件的文档/对象，这些条件符合以下条件：其叶元素/字段：statusInfo/status不是“UP”，并且在那些过滤的对象中，只需返回 "name" , "serviceUrl","status"

例子 ：

"ADMIN-V1"  "http://aws-ec2.aws.com:4435"  "Warning"

我一直在研究 JSONPath 模块，但是没有关于它的好的文档，我找不到更简单的方法。非常感谢任何指导。

这是来自 16000 行 JSON 响应的片段。

如果您的 json 文件包含一个大数组，则您需要流式传输该文件以截断该数组。然后用于fromstream/1重建对象并随时过滤掉它们。

我自己没有代表文件来测试性能，但试试看：

$ jq --stream -n 'fromstream(1|truncate_stream(inputs))
    | select(.statusInfo.status != "UP")
    | .name, .serviceUrl, .statusInfo.status
' input.json
