java.lang.IllegalArgumentException：不能有replace块。对于动态查询参数，请使用@Query

我正在尝试使用具有'convert'终结点的API将USD转换为INR b，这是向下的错误，我在该错误下反复遇到

java.lang.IllegalArgumentException: URL query string "api_key={api_key}&base={base}&to={to}&amount={amount}" must not have replace block. For dynamic query parameters use @Query.

//这里是我正在创建改造对象的班级

公共类MainActivity扩展了AppCompatActivity实现的View.OnClickListener {
