How to send post request with basic auth in retrofit?

Question

In my code, I want to send post request with basic auth.

Here is my postman screenshot :

here is my apiInterface class

@FormUrlEncoded
    @POST("GetBarcodeDetail")
    Call<PreliminaryGoodsAcceptResponse> PRELIMINARY_GOODS_ACCEPT_RESPONSE_CALL(@Field("ProcName") String procName, @Field("Barcode") String barcode, @Field("LangCode") String langCode);

here is my apiclient

public class ApiClient {

    public static final String BASE_URL = "http://192.**********";
    private static Retrofit retrofit = null;
    private static OkHttpClient sClient;

    public static Retrofit getClient() {
        if(sClient == null) {
            HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
            interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
            sClient = new OkHttpClient.Builder()
                    .addInterceptor(new HttpLoggingInterceptor(HttpLoggingInterceptor.Logger.DEFAULT))
                    .addInterceptor(interceptor)
                    .build();
        }

        if (retrofit==null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(sClient)
                    .build();
        }
        return retrofit;
    }

}

My question is how can i send post request,using header :

Header Username : EBA Token :
34242353453456563DSFS

Answer 1

This is so far the easiest method i have ever tried for "Basic Authentication".

Use the below code to generate the auth header (API/Repository class)

 var basic = Credentials.basic("YOUR_USERNAME", "YOUR_PASSWORD")

Pass this as header to the webservice call (API/Repository class)

 var retrofitCall = myWebservice.getNewsFeed(basic)

Add the basic header as parameter (Retrofit Webservice interface class)

 @GET("newsfeed/daily")
 fun getNewsFeed(@Header("Authorization") h1:String):Call<NewsFeedResponse>

Sorry, my code is in Kotlin, but can be easily translated to Java.

Use Header annotation

@FormUrlEncoded
    @POST("GetBarcodeDetail")
    Call<PreliminaryGoodsAcceptResponse> PRELIMINARY_GOODS_ACCEPT_RESPONSE_CALL(@Header("Authorization") token: String,@Field("ProcName") String procName, @Field("Barcode") String barcode, @Field("LangCode") String langCode);
