我也陷入了类似的情况，setLevel()方法没有到来，当我试图用HttpLoggingInterceptor的实例调用它时， 是这样的:

HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

这是我解决它的方法，为Retrofit2生成日志，

我猜你增加了依赖关系，

implementation "com.squareup.okhttp3:logging-interceptor:4.7.2"

对于最新的版本，你可以查看，这个链接:

https://github.com/square/okhttp/tree/master/okhttp-logging-interceptor)

这里他们也解释了如何添加。

我创建了一个名为AddLoggingInterceptor的类， 这是我的代码，

public class AddLoggingInterceptor {

    public static OkHttpClient setLogging(){
        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

        OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .addInterceptor(loggingInterceptor)
                .build();

        return okHttpClient;
    }
}

然后，在我们实例化我们的Retrofit时，

 public static Retrofit getRetrofitInstance() {
    if (retrofit == null) {
        retrofit = new retrofit2.Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .client(AddLoggingInterceptor.setLogging()) // here the method is called inside client() method, with the name of class, since it is a static method.
                .build();
    }
    return retrofit;
}

现在你可以看到日志生成在你的Android工作室，你可能需要搜索，okHttp过滤过程。这对我很管用。如果有任何问题，你可以给我发短信。

如果您正在使用Retrofit2和okhttp3，那么您需要知道Interceptor是通过队列工作的。所以在你的其他interceptor之后添加loggingInterceptor:

HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        if (BuildConfig.DEBUG)
            loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.HEADERS);

 new OkHttpClient.Builder()
                .connectTimeout(60, TimeUnit.SECONDS)
                .readTimeout(60, TimeUnit.SECONDS)
                .writeTimeout(60, TimeUnit.SECONDS)
                .addInterceptor(new CatalogInterceptor(context))//first
                .addInterceptor(new OAuthInterceptor(context))//second
                .authenticator(new BearerTokenAuthenticator(context))
                .addInterceptor(loggingInterceptor)//third, log at the end
                .build();

我面临的主要问题是动态添加头文件并将它们记录到调试日志中。我试着增加两个拦截器。一个用于日志记录，一个用于添加动态报头(令牌授权)。问题是我们可以。addinterceptor或。addnetworkinterceptor。正如Jake Wharton对我说的:“网络拦截器总是紧跟在应用程序拦截器之后。看到https://github.com/square/okhttp/wiki/Interceptors”。下面是头文件和日志的工作示例:

OkHttpClient httpClient = new OkHttpClient.Builder()
            //here we can add Interceptor for dynamical adding headers
            .addNetworkInterceptor(new Interceptor() {
                @Override
                public Response intercept(Chain chain) throws IOException {
                    Request request = chain.request().newBuilder().addHeader("test", "test").build();
                    return chain.proceed(request);
                }
            })
            //here we adding Interceptor for full level logging
            .addNetworkInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY))
            .build();

    Retrofit retrofit = new Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create(gsonBuilder.create()))
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .client(httpClient)
            .baseUrl(AppConstants.SERVER_ADDRESS)
            .build();

芬兰湾的科特林代码

        val interceptor = HttpLoggingInterceptor()
        interceptor.level = HttpLoggingInterceptor.Level.BODY
        val client = OkHttpClient.Builder().addInterceptor(interceptor).build()
        val retrofit = Retrofit.Builder()
                .baseUrl(BASE_URL)
                .client(client)
                .addConverterFactory(GsonConverterFactory.create())
                .build()

        return retrofit.create(PointApi::class.java)

对于Retrofit 2.0.2，代码如下:

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient.Builder httpClient=new OkHttpClient.Builder();
        httpClient.addInterceptor(logging);

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

更新日志

Retrofit的拦截器是一个很好的功能，它允许你处理http请求。 它们有两种类型:应用程序拦截器和网络拦截器。

如果您需要记录请求/响应，我建议使用Charles Web调试代理应用程序。输出与Stetho非常相似，但它是更强大的工具，不需要将其作为依赖项添加到应用程序中
