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)

在Retrofit 2中做到这一点的最好方法是添加记录器拦截器作为networkInterceptor，这将打印出网络头和您的自定义头。重要的是要记住，拦截器作为一个堆栈工作，并确保在所有的末尾添加记录器。

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.addInterceptor(new MyCustomInterceptor());
builder.connectTimeout(60, TimeUnit.SECONDS);
builder.readTimeout(60, TimeUnit.SECONDS);
builder.writeTimeout(60, TimeUnit.SECONDS);
// important line here
builder.addNetworkInterceptor(LoggerInterceptor());

我不知道setLogLevel()是否会在最终2.0版本的Retrofit中返回，但现在你可以使用一个拦截器来记录日志。

一个很好的例子可以在OkHttp wiki上找到:https://github.com/square/okhttp/wiki/Interceptors

OkHttpClient client = new OkHttpClient();
client.interceptors().add(new LoggingInterceptor());

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("http://www.yourjsonapi.com")
        .addConverterFactory(GsonConverterFactory.create())
        .client(client)
        .build();

嘿，伙计们，我已经找到解决方案了:

  public static <T> T createApi(Context context, Class<T> clazz, String host, boolean debug) {
    if (singleton == null) {
        synchronized (RetrofitUtils.class) {
            if (singleton == null) {
                RestAdapter.Builder builder = new RestAdapter.Builder();
                builder
                        .setEndpoint(host)
                        .setClient(new OkClient(OkHttpUtils.getInstance(context)))
                        .setRequestInterceptor(RequestIntercepts.newInstance())
                        .setConverter(new GsonConverter(GsonUtils.newInstance()))
                        .setErrorHandler(new ErrorHandlers())
                        .setLogLevel(debug ? RestAdapter.LogLevel.FULL : RestAdapter.LogLevel.NONE)/*LogLevel.BASIC will cause response.getBody().in() close*/
                        .setLog(new RestAdapter.Log() {
                            @Override
                            public void log(String message) {
                                if (message.startsWith("{") || message.startsWith("["))
                                    Logger.json(message);
                                else {
                                    Logger.i(message);
                                }
                            }
                        });
                singleton = builder.build();
            }
        }
    }
    return singleton.create(clazz);
}

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。

你也可以添加Facebook的Stetho，在Chrome中查看网络痕迹: http://facebook.github.io/stetho/

final OkHttpClient.Builder builder = new OkHttpClient.Builder();
if (BuildConfig.DEBUG) {
    builder.networkInterceptors().add(new StethoInterceptor());
}

然后打开“chrome://inspect”在chrome…
