我的問題是，我的密鑰將具有非固定值，就像在 python 中一樣，我們可以這樣做：dict_ = {}data_ = [{"name": "roy", "text": "yay i got a gift"},{"name": "dep", "text": "my mum gimme a gift"},{"name": "roy", "text": "another gift from my fan"}]for data in data_:    key = data["name"]    if key in dict_:        dict_[key] += 1 // add more 1 if key already in dict_    else:        dict_[key] = 1 // set dict key with starting value 1我正在嘗試用 golang 做，謝謝
