如何将数组拆分成嵌套的json对象

我正试图处理来自 this library 因为我需要它们是嵌套的JSON对象。

错误最初似乎是一个数组,如下所示:

["String length must be greater than or equal to 3","Does not match format 'email'"]

我还需要包含包含错误的字段名:

["Field1: String length must be greater than or equal to 3","Email1: Does not match format 'email'"]

之后,我需要用冒号分隔每个数组值 : 所以我可以将字段名和错误描述放在单独的变量中,比如 slice[0] 和 slice[1] .

因此,我想创建一个嵌套的JSON对象,如下所示:

{
    "errors": {
        "Field1": "String length must be greater than or equal to 3",
        "Email1": "Does not match format 'email'"
    }
}

这是我实现这一目标的方法:

var errors []string
for _, err := range result.Errors() {
    // Append the errors into an array that we can use to split later
    errors = append(errors, err.Field() + ":" + err.Description())
}

// Make the JSON map we want to append values to
resultMap := map[string]interface{}{
    "errors": map[string]string {
        "Field1": "",
        "Email1": ""
    },
}

// So we actually can use the index keys when appending
resultMapErrors, _ := resultMap["errors"].(map[string]string)

for _, split := range errors {
    slice := strings.Split(split, ":")
    for _, appendToMap := range resultMapErrors {
        appendToMap[slice[0]] = slice[1] // append it like so?
    }
}

finalErrors, _ := json.Marshal(resultMapErrors)
fmt.Println(string(finalErrors))

但这会造成错误

main.go:59:28: non-integer string index slice[0]
main.go:59:39: cannot assign to appendToMap[slice[0]]
