在go中用逗号分割字符串后，获得[]接口{}

Question

I have two ways to get a list.

1. via api - which returns me a map[string]interface{}. The value I am interested in is stored in interface as []interface{} (array of strings which are by default set to array of interface)
2. via static string - if api fails. This is a comma separated string. I use the strings.Split function which results in an []string

The above results in data of two types []interface{} and []string which is not compatible for the operations an I will have to perform same operation separately based on the type.

Further I am converting the array to a map[string]int with key as string and value as 1. I am converting it to a map for quick checking of some attributes in the original array

Is there any solution to the problem and what is the best way to do it..

Answer 1

Use the following code to create a map[string]int from comma separated values in a string s:

m := make(map[string]int)
for _, p := range strings.Split(s, ",") {
   m[p] = 1
}

Use the following code to create a map[string]int from values of type []interface{}:

m := make(map[string]int)
for _, v := range values {
   s, ok := v.(string)
   if !ok {
      // not a string, handle error
   }
   m[s] = 1
}
