Retrofit2中如何添加Header

Question

我很困惑，我已将令牌保存在 SharedPrefernce 中，当我尝试获取用户名时，即使我已经使用了 Header 和 Sharedpref，我仍然无法取消 object 偏好令牌。也许我的错误是没有给改造 Header。在这里我很困惑父亲添加 header。我使用了现有的参考资料，但没有用。求教有什么办法希望大家帮帮我

RetrofitClient.java

public class RetrofitClient {

        SharedPrefManager sharedPrefManager;
        private static Retrofit retrofit = null;

        public static Retrofit getClient(String baseUrl){
            HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
            interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
            OkHttpClient client = new OkHttpClient.Builder()
                                        .addInterceptor(interceptor)
                                        .build();

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

此令牌保存

SharedPrefManager sharedPrefManager;
sharedPrefManager.getSPToken()

这是改造客户端示例

 public class RetrofitClient {


        private static Retrofit retrofit = null;

        public static Retrofit getClient(String baseUrl){
            HeaderInterceptor interceptor = new HeaderInterceptor();
            OkHttpClient client = new OkHttpClient.Builder()
                    .addInterceptor(interceptor)
                    .build();

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

您的用例的拦截器。

public class HeaderInterceptor implements Interceptor {

    SharedPrefManager sharedPrefManager = new SharedPrefManager();

    @Override
    public Response intercept(Chain chain) throws IOException {

        Request originalRequest = chain.request();

        Request newRequest = originalRequest.newBuilder()
                .header("Language", sharedPrefManager.getSPToken())
                .build();

        return chain.proceed(newRequest);

    }
}
