拦截器添加请求头

okHttpClient = new OkHttpClient.Builder()
.addNetworkInterceptor(httpLoggingInterceptor)
.addInterceptor(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Request build = chain.request().newBuilder().addHeader(“userId”, “11249”)
.addHeader(“sessionId”, “155056366467311249”)
.build();
Response proceed = chain.proceed(build);

                    return proceed;
                }
            })
            .writeTimeout(20, TimeUnit.SECONDS)
            .connectTimeout(20, TimeUnit.SECONDS)
            .readTimeout(20, TimeUnit.SECONDS)
            .build();
