how to validate json data in laravel

Question

Here is the json data I send through postman for 'specification' field:

{
"specification": [
    {
      "type": [
          {
              "type": "Smartphone , Phablet , Notch Phone , Camera Phone , Selfie Phone",
              "shape": "Bar"
          }
      ],
      "basic": [
          {
              "os": "Smartphone , Phablet , Notch Phone , Camera Phone , Selfie Phone",
              "Sim": "Bar"
          }
      ]
    }
  ]
}

Then in controller the validation rule is:

'specification' => 'required|json'

The error message: "The specification must be a valid JSON string."

how can I send and check valid json in laravel controller?

From documentation:

json

The field under validation must be a valid JSON string.

Your data has been parsed from JSON by Laravel itself, and specification is an array already, not a JSON string. You can check that by changing your rule to required|array and you'll see that it passes.

@TapashDatta Perhaps you could share more information how exactly you're sending this request: headers, body etc.

The string you are posting here is not a valid json string. A valid json string starts and ends with { and }. So in your case it should be like this:

{
    "specification": [{
        "type": [{
            "type": "Smartphone , Phablet , Notch Phone , Camera Phone , Selfie Phone",
            "shape": "Bar"
        }],
        "basic": [{
            "os": "Smartphone , Phablet , Notch Phone , Camera Phone , Selfie Phone",
            "Sim": "Bar"
        }]
    }]
}
