在 Retrofit 2 日志记录中看不到标头

Question

我正在使用 Retrofit2 发出网络请求，我想向它添加一个标头。设置标题后，我设置了一个日志机制来查看日志。这是我现在看到的，请求中没有标头。

07-19 18:17:41.553 23344-24481/com.carlos.capstone.debug D/OkHttp: --> GET http://finance.yahoo.com/webservice/v1/symbols/AMZN,GOOG,ORCL,%5ENDX,/quote?format=json&view=detail http/1.1
07-19 18:17:41.553 23344-24481/com.carlos.capstone.debug D/OkHttp: --> END GET

以下是涉及的类： 我设置了一个 HeaderInterceptor，在其中将标头设置为请求，然后进行日志记录。

public class IndexOrShortInfoRApi {
    public static IIndexOrShortInfoData myService;
    public interface IIndexOrShortInfoData {

        @GET("/webservice/v1/symbols/TX60.TS,^GSPTSE,^IXIC,^NDX,^DJI,^GSPC,^BVSP,^MXX,^MERV,^IPSA/quote?format=json&view=detail")
        Call<IndexOrShortInfoDataResponse> getIndexesAmerica();
        @GET("/webservice/v1/symbols/^STOXX50E,^FTSE,^GDAXI,^FCHI,^IBEX,FTSEMIB.MI,PSI20.LS,BEL20.BR,^BFX,^SSMI,OBX.OL,RTS.RS,OMXC20.CO,^OMXSPI,^SSMI,FPXAA.PR,GD.AT,^ATX,^ISEQ/quote?format=json&view=detail")
        Call<IndexOrShortInfoDataResponse> getIndexesEurope();
        @GET("/webservice/v1/symbols/^N225,000001.SS,^AXJO,^AORD,^HSI,^BSESN,^NSEI,^NZ50,^TWII,^JKSE,^KLSE,^KS11,^STI,PSEI.PS/quote?format=json&view=detail")
        Call<IndexOrShortInfoDataResponse> getIndexesAsia();
        @GET("/webservice/v1/symbols/{ticker}/quote?format=json&view=detail")
        Call<IndexOrShortInfoDataResponse> getSecurityShortInfoByTicker(@Path("ticker") String ticker);
    }

    public static IIndexOrShortInfoData getMyService(){
        //OkHttpClient client=new OkHttpClient();

        HttpLoggingInterceptor logging=new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.HEADERS);
        Dispatcher dispatcher=new Dispatcher();
        dispatcher.setMaxRequests(3);

        OkHttpClient client=new OkHttpClient.Builder()
                .dispatcher(dispatcher)
                .addInterceptor(new HeaderInterceptor())
                .addInterceptor(logging)
                .build();

        if (myService==null) {
            Retrofit retrofit=new Retrofit.Builder()
                    .baseUrl("http://finance.yahoo.com/")
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(client)
                    .build();
            myService=retrofit.create(IIndexOrShortInfoData.class);
            return myService;

        } else {
            return myService;
        }

    }
}

设置标题的类：

public class HeaderInterceptor implements Interceptor {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request =chain.request();
        request.newBuilder()
                .addHeader("User-Agent","Mozilla/5.0 (Linux; Android 6.0.1; MotoG3 Build/MPI24.107-55) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.81 Mobile Safari/537.36")
                .build();
        Log.d("Retrofit", request.headers().toString());
        Response response=chain.proceed(request);
        return response;

    }
}

我什至看不到 Log.d("Retrofit", request.headers().toString())。似乎 HeaderInterceptor 类没有实例化，但我无法看到错误在哪里。提前致谢！

抱歉，我没有将设置标头的结果分配给变量，因此未将其包含在请求中：

解决方案：

 request=request.newBuilder()
                .addHeader("User-Agent","Mozilla/5.0 (Linux; Android 6.0.1; MotoG3 Build/MPI24.107-55) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.81 Mobile Safari/537.36")
                .build();
        Log.d("Retrofit", request.headers().toString());
