Jq到string过滤器

Question

尝试过滤来自Json的输出，到目前为止，当软件版本不存在时，当软件版本被找到时，使用的过滤器将按预期工作，jq将导致错误。基本上，如何在csv文件中转义()并返回空值。

.result [] | [ "https://vuldb.com/?id." + .entry.id ,.software.vendor // "empty"
,.software.name // "empty", (.software.version []| tostring // "empty")
,.software.type // "empty"
,.software.platform //"empty" ]

Answer 1

抑制错误并为空值提供一个替代方案：

.result | map(
    "https://vuldb.com/?id.\(.entry.id)",
    (
        .software |
        .vendor // "empty",
        .name // "empty",
        (.version[] | tostring // "empty")? // "no version",
        .type // "empty",
        .platform // "empty"
    )
)
