RestTemplate 활용

RestCall.kt

    private fun getResponse(disqusOauthUrl: String): ResponseEntity<String> {
        val endpoint = URI.create(disqusOauthUrl)
        val req = RequestEntity<Any>(HttpMethod.GET, endpoint)
        val resType = object : ParameterizedTypeReference<String>() {}
        return RestTemplate().exchange<String>(req, resType)
    }
