How to Get All Objects with Jsonpaths in Golang
I Am Using Jsonpath in Golang but I Can't Get All the Objects of the Following Json That Contain in Type iPhone: { "Firstname": "John", "Lastname": "Doe"...
I am using jsonpath in golang but I can't get all the objects of the following json that contain in type iPhone:
{
"firstName": "John",
"lastName": "doe",
"age": 26,
"address": {
"streetAddress": "naist street",
"city": "Nara",
"postalCode": "630-0192"
},
"phoneNumbers": [
{
"type": "iPhone",
"number": "0123-4567-8888"
},
{
"type": "home",
"number": "0123-4567-8910"
},
{
"type": "iPhone",
"number": "0123-4567-8910"
}
]}
I am working with golang and I know that the following jsonpath works:
$.phoneNumbers[?(@.type == "iPhone")]
The problem I have is that it is a service in which I have input a json path like the following:
$.[*].phoneNumbers[*].type
And the value that I have to look for, I am doing it in the following way:
values, err := jsonpath.Get(jsonPath, data)
for _, value := range values {
if err != nil {
continue
}
if value.(string) == "iPhone" {
}
}
At this point I cant get the output like:
[{
"type": "iPhone",
"number": "0123-4567-8888"
},
{
"type": "iPhone",
"number": "0123-4567-8888"
}]
I cant use the [?(@.)] format it is necessary to make with if. Any idea? Thanks

I cooked up an example using Peter Ohler's ojg package. Here's what the implementation looks like:
package main
import (
"fmt"
""
""
)
var jsonString string = `{
// Your JSON string
}`
func main() {
obj, err := oj.ParseString(jsonString)
if err != nil {
panic(err)
}
x, err := jp.ParseString(`$.phoneNumbers[?(@.type == "iPhone")]`)
if err != nil {
panic(err)
}
ys := x.Get(obj)
for k, v := range ys {
fmt.Println(k, "=>", v)
}
}
// Output:
// 0 => map[number:0123-4567-8888 type:iPhone]
// 1 => map[number:0123-4567-8910 type:iPhone]
