Json path expression for value match-CodePudding

Here, I want to verify if the user's name is john doe or not.

{
    "name": "John doe",
    "age": 26,
    "address": {
        "streetAddress": "naist street",
        "city": "Nara"
    },
    "phoneNumbers": [
        {
            "type": "iPhone",
            "number": "0123-4567-8888"
        }
    ]
}

I have tried $.firstName[?(@.=='John')] and $[?(@.firstName=='John')] but nothing is working.

CodePudding user response：

Since you've tagged the question xpath, the XPath 3.1 solution is

?name = "John doe"

Earlier versions of XPath do not have JSON support.

CodePudding user response：

You have to point what do you want to use jsonpath or xpath. By the samples in you question I can guess that you are trying jsonpath. Since there is no a first name in your json, try this

$[?(@ == 'John doe')]  //  result ["John doe"]

but i would use just this

var ifJohnExist =user.name.includes("John");

IMHO nobody is using jsonpath this way, jsonpath is created for a search. So if your json is like this

var user=[{
  "name": "John doe",
  "age": 26,
  "address": {
      "streetAddress": "naist street",
      "city": "Nara"
  },
  "phoneNumbers": [
      {
          "type": "iPhone",
          "number": "0123-4567-8888"
      }
  ]
}];

then you can use jsonpath, to find an array element that contains that name

$[?(@.name.includes('John'))].name //result ["John doe"]

and remember that json path is always returning an array
