When golang operates mongodb, vscode prompts primitive E composite literal uses unlocked fields

cannot use "category_title" (untyped string constant) as primitive.E value in array or slice literal (compile)go-staticcheck

According to my current experience , When using bson.D This prompt will appear when . Although it does not affect operation , But it's always uncomfortable . Using Baidu Dafa, I found only one paragraph of English information , I tried to understand the general meaning by looking up the dictionary , The writing is not standard .

filter := bson.D{
   {"category_title", " Online total "}}

Like the above paragraph , Need to add key and value Change to the following ：

filter := bson.D{primitive.E{Key:"category_title", Value:" Online total "}}

It can also be simplified a little , Don't primitive.E：

filter := bson.D{
   {Key:"category_title", Value:" Online total "}}

It's ok .

If the sequence is not required , It can be used bson.M, It's simpler , like this ：

filter := bson.M{"category_title": " Online total "}

Actually, I'm a beginner , If there is anything wrong , Please tell me , Common progress , Thank you ！
