Question

我需要阅读下面的json响应后的波谷

我正在搜索特殊文件夹的ID。我知道较深的级别，因为我知道整个路径，所以我希望在其中找到该文件夹。我需要找回文件夹的ID。

我知道的是我要查找的文件夹的整个路径，例如/ Core / UI / Folder1 / Subfolder2 所以我需要subfolder2的ID。

我尝试了几次循环，但由于进行了深入搜索而失败了。当然，我可以编写一些深层次的手册，但这听起来并不是我认为的正确方法。

示例JSON

    "folders": [
        {
            "rank": 1,
            "name": "Core",

好的，如果我对您的理解正确，那应该可以，请告诉我

data = {
    "folders": [
        {
            "rank": 1,
            "name": "Core",
            "id": 390,
            "testCount": 0,
            "totalTestCount": 0,
            "testRepositoryPath": "",
            "folders": [
                {
                    "rank": 1,
                    "name": "UI",
                    "id": 391,
                    "testCount": 0,
                    "totalTestCount": 0,
                    "testRepositoryPath": "/Core",
                    "folders": [
                        {
                            "rank": 1,
                            "name": "Folder1",
                            "id": 392,
                            "testCount": 0,
                            "totalTestCount": 0,
                            "testRepositoryPath": "/Core/UI",
                            "folders": [
                                {
                                    "rank": 1,
                                    "name": "Subfolder2",
                                    "id": 393,
                                    "testCount": 0,
                                    "totalTestCount": 0,
                                    "testRepositoryPath": "/Core/UI/Folder1",
                                    "folders": []
                                }
                            ]
                        }
                    ]
                }
            ]
        }
    ],
    "allTestsCount": 791,
    "allOrphanTestsCount": 791
}


def extract_inner_id(d, path):
    try:
        current_path = d['testRepositoryPath'] + '/' + d['name']
        if current_path == path:
            return d['id']
    except KeyError:
        pass
    for sub_d in d['folders']:
        inner_id = extract_inner_id(sub_d, path)
        if inner_id is not None:
            return inner_id
    return None


print(extract_inner_id(data, "/Core/UI/Folder1/Subfolder2"))

请注意，我们从内部为每个子文件夹调用extract_inner_id，这是无论深度如何我们都可以进行搜索的方式。
