嗨，我正在尝试在迭代时导入一个 json 文件，以便将某些值插入到数据库中。在这种情况下，我需要 artifactid，插入版本。 json 文件有一个列表，所以我会有多个插入。我认为我在正确的轨道上，任何帮助将不胜感激。目前这是我在 parsed['groupId'].values() 中遇到的错误： TypeError: 列表索引必须是整数或切片，而不是 str

Answer 1

'parsed' 是一个列表，而不是一个字典。它包含字典。每个字典都包含一个名为“groupId”的字段。所以你的代码应该是这样的。

如果以下代码不适合您，请将“JSON/Java.json”上传到公共位置。

for entry in parsed:
    # entry is a dict - do something with it
