Error : CLEARTEXT communication to XXXX not permitted by network security policy

• Base Url 에 https가 아닌 http를 쓰면 CLEARTEXT communication to XXXX not permitted by network security policy 오류가 난다.
• 해결방법 1 : BASE URL을 http -> https로 바꿈
• 해결방법 2 : Manifest에 usesCleartextTraffic 속성을 true로 설정

<application
   ...
   android:usesCleartextTraffic="true">

Path

• https://example.com/user/4z7l 인 경우 : @Path 사용

interface UserService {
    @GET("users/{name}")
    fun getUser(
        @Path("name") userName: String
    ): Call<User>
}

• https://example.com/user?q=4z7l 인 경우 : @Query 사용

interface UserService {
    @GET("users")
    fun getUser(
        @Query("q") userName: String
    ): Call<User>
}
