如何使用retrofit2添加基本身份验证？

implementation 'com.squareup.retrofit2:retrofit:2.x.x'
implementation 'com.squareup.retrofit2:converter-gson:2.x.x'

public interface ApiService {
    @Headers("Authorization: Basic your_base64_encoded_credentials")
    @GET("your/api/endpoint")
    Call<YourResponseModel> getYourData();
}

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request original = chain.request();
        Request.Builder requestBuilder = original.newBuilder()
                .header("Authorization", "Basic your_base64_encoded_credentials")
                .method(original.method(), original.body());
        Request request = requestBuilder.build();
        return chain.proceed(request);
    }
});

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.example.com/")
        .client(httpClient.build())
        .addConverterFactory(GsonConverterFactory.create())
        .build();

ApiService apiService = retrofit.create(ApiService.class);

Call<YourResponseModel> call = apiService.getYourData();
call.enqueue(new Callback<YourResponseModel>() {
    @Override
    public void onResponse(Call<YourResponseModel> call, Response<YourResponseModel> response) {
        if (response.isSuccessful()) {
            YourResponseModel data = response.body();
            // 处理返回的数据
        } else {
            // 处理请求失败
        }
    }

    @Override
    public void onFailure(Call<YourResponseModel> call, Throwable t) {
        // 处理请求失败
    }
});
