I'm having an issue when I'm try to iterate through a map of some json.
The original JSON data looks like this:
"dataArray": [
{
"name": "default",
"url": "/some/url"
},
{
"name": "second",
"url": "/another/url"
}
]
the map looks like this:
[map[name:default url:/some/url] map[name:second url:/another/url]]
The code looks like this:
for _, urlItem := range item.(map[string]interface{}){
do some stuff
}
This normally works when it's a JSON object, but this is an array in the JSON and I get the following error:
panic: interface conversion: interface {} is []interface {}, not map[string]interface {}
Any help would be greatly appreciated
The error is :
panic: interface conversion: interface {} is []interface {}, not map[string]interface {}
in your code you're converting item
into map[string]interface{}
:
for _, urlItem := range item.(map[string]interface{}){
do some stuff
}
But the actual item
is []interface {}
: change your covert type to this.
Because as you can see your result data is :
[map[name:default url:/some/url] map[name:second url:/another/url]]
it is an array
that has map
. not map
.
First you can convert your data to []interface{}
and then get the index of that and convert it to map[string]interface{}
. so an example will look like this :
data := item.([]interface{})
for _,value := range data{
yourMap := value.(map[string]interface{})
//name value
name := yourMap["name"].(string) // and so on
}
