Golang json Unmarshal“ JSON输入意外结束”

Question

I am working on some code to parse the JSON data from an HTTP response. The code I have looks something like this:

type ResultStruct struct {
    result []map[string]string
}

var jsonData ResultStruct
err = json.Unmarshal(respBytes, &jsonData)

The json in the respBytes variable looks like this:

{
 "result": [
  {
   "id": "ID 1"
  },
  {
   "id": "ID 2"
  }
 ]
}

However, err is not nil. When I print it out it says unexpected end of JSON input. What is causing this? The JSON seems to valid. Does this error have something to do with my custom struct?

Thanks in advance!
