OkHttp의 Network Interceptor

2가지의 Interceptors

 

 

아래와 같이 Retrofit builder에 interceptor를 넣어서 디버깅하면 편리 하다. 

아래 주석을 한 것처럼 원하는 데이터만 출력 하는 방법이 있는가 하면,

HttpLoggingInterceptor 객체를 생성하여 level만 정해 주고 그냥 쓰는 방법이 있다.

HttpLoggingInterceptor로 왠만한 정보를 볼 수 있다.

interface GithubApi {

    @GET
    fun getUserList(@Url url: String) : Observable<UserResponse>
}

object GithubApiProvider {
    fun provideGithubApi(): GithubApi {
        return Retrofit.Builder()
            .baseUrl(Constant.BASE_URL)
            .client(provideOkHttpClient(provideLoggingInterceptor()))
            .addCallAdapterFactory(RxJava2CallAdapterFactory.createAsync())
            .addConverterFactory(GsonConverterFactory.create())
            .build()
            .create(GithubApi::class.java)
    }


    private fun provideOkHttpClient(interceptor: HttpLoggingInterceptor): OkHttpClient {
        var builder = OkHttpClient.Builder()
        builder.addInterceptor(interceptor)         // Application Interceptors : Application Interceptor를 등록하려면 OkHttpClient.Builder에서 addInterceptor()를 호출해야 합니다.
        return builder.build()
    }


    private fun provideLoggingInterceptor(): HttpLoggingInterceptor {
        var interceptor = HttpLoggingInterceptor()
        interceptor.level = HttpLoggingInterceptor.Level.BODY
        return interceptor
    }

//
//    private fun provideOkHttpClient(interceptor: Interceptor) : OkHttpClient{
//        var builder = OkHttpClient.Builder()
//        builder.addInterceptor(interceptor)
//
//        return builder.build()
//    }
//
//    private fun provideLoggingInterceptor(): Interceptor{
//
//        return object : Interceptor{
//            val TAG = javaClass.simpleName
//            override fun intercept(chain: Interceptor.Chain): Response {
//                var request = chain.request()
//                Log.d(TAG, "request.method" + request.method())
//
//                var response = chain.proceed(request)
//                Log.d(TAG, "response.url" + response.request().url())
//
//                return response
//            }
//        }
//    }

}

 

... {
	... 
	private var api = GithubApiProvider.provideGithubApi()
	disposable.add(api.getUserList(Constant.BASE_URL + Constant.RANDOM_USER_URL)!!    
    ... 
    
}

또 다른 샘플 코드

val okHttpClient = OkHttpClient.Builder()
            .addInterceptor { chain: Interceptor.Chain ->
                val original = chain.request()
                chain.proceed(original.newBuilder().apply {
                    addHeader("X-Naver-Client-Id", Naver_Client_Id)
                    addHeader("X-Naver-Client-Secret", Naver_Client_Secret)
                }.build())
            }
            .addInterceptor(HttpLoggingInterceptor().apply {
                level = HttpLoggingInterceptor.Level.BODY
            }).build()

        val retrofit = Retrofit.Builder()
            .baseUrl(BASE_URL)
            .client(okHttpClient)
            .addConverterFactory(GsonConverterFactory.create())
            .build()
