使用json路径从json中提取值

Question

我尝试根据以下json中的电子邮件值提取id值：

[
{"id":11,"username":"John","address":"London","email":"john@test.com"},
{"id":12,"username":"Piere","address":"Paris","email":"piere@test.com"},
{"id":13,"username":"Anne","address":"Moscow","email":"anne@test.com"},
]

我的表达是

$..[?(@.email=='anne@test.com')].id

它不起作用。这个表达有什么问题？

Answer 1

你的表情是正确的。我认为您需要更正您的JSON数据。存在语法错误。 这是正确的：

[
{"id":11,"username":"John","address":"London","email":"john@test.com"},
{"id":12,"username":"Piere","address":"Paris","email":"piere@test.com"},
{"id":13,"username":"Anne","address":"Moscow","email":"anne@test.com"}
]

您可以使用它来下次验证您的JSON。
