[英]Extract nested element value from JSON object using JMESPath
I am trying to extract and transform elements from a JSON document using JMESPath
. 我正在尝试使用
JMESPath
从JSON文档中提取和转换元素。 Here is my test JSON array: 这是我的测试JSON数组:
const search = jmespath.search;
const testData =
{
"ServiceAccount": [
{
"Type": "WIDGET",
"ID": [
{
"OrderNum": "12345",
"OrderTyp": "ABDCD"
}
]
}
]
};
I am trying to extract the value of the OrderNum
key using the following JMESPath expression, but it returns null
. 我正在尝试使用以下JMESPath表达式提取
OrderNum
键的值,但它返回null
。 Here is my search expression: 这是我的搜索表达式:
const result = search(testData, 'ServiceAccount.ID.OrderNum');
console.log(result);
Why is this not working? 为什么这不起作用?
const testData =
{
"ServiceAccount": [
{
"Type": "WIDGET",
"ID": [
{
"OrderNum": "12345",
"OrderTyp": "ABDCD"
}
]
}
]
};
const result = jmespath.search(testData, 'ServiceAccount[].ID[].OrderNum');
console.log(result);
