在我使用Retrofit 2时，有没有办法在发送数据之前知道值/结构

Question

我使用Retrofit 2，我想知道将值发送到服务器的值或结构。有什么方法我可以把'system.out.print＆＃39;这样我才能知道我发送了什么？

Answer 1

首先添加此

impletemtaion "com.squareup.okhttp3:logging-interceptor:LATEST_VERSION";

添加此

    @Provides
    @Singleton
    public OkHttpClient provideClient(Context mContext, CacheInterceptor cacheInterceptor, HeaderInterceptor headerInterceptor) {
        //***************
        HttpLoggingInterceptor logger = new HttpLoggingInterceptor();
        logger.setLevel(HttpLoggingInterceptor.Level.BODY);
        //***************
        return new okhttp3.OkHttpClient.Builder()
                    .addInterceptor(logger)
                    .addInterceptor(headerInterceptor)
                    .connectTimeout(Constant.CONNECTTIMEOUT, TimeUnit.SECONDS)
                    .readTimeout(Constant.READTIMEOUT, TimeUnit.SECONDS)
                    .writeTimeout(Constant.WRITETIMEOUT, TimeUnit.SECONDS)
                    .build();

    }
