JSONArray.query介绍

[英]Creates a JSONPointer using an initialization string and tries to match it to an item within this JSONArray. For example, given a JSONArray initialized with this document:

[ 
{"b":"c"} 
]

and this JSONPointer string:

"/0/b"

Then this method will return the String "c" A JSONPointerException may be thrown from code called by this method.
[中]使用初始化字符串创建JSONPointer，并尝试将其与此JSONArray中的项相匹配。例如，给定一个使用以下文档初始化的JSONArray:

[ 
{"b":"c"} 
]

和此JSONPointer字符串：

"/0/b"

则此方法将返回字符串“c”，此方法调用的代码可能会引发JSONPointerException。
