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)

对于那些需要在Retrofit中进行高级日志记录的人，可以像这样使用拦截器

public static class LoggingInterceptor implements Interceptor {
    @Override public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        long t1 = System.nanoTime();
        String requestLog = String.format("Sending request %s on %s%n%s",
                request.url(), chain.connection(), request.headers());
        //YLog.d(String.format("Sending request %s on %s%n%s",
        //        request.url(), chain.connection(), request.headers()));
        if(request.method().compareToIgnoreCase("post")==0){
            requestLog ="\n"+requestLog+"\n"+bodyToString(request);
        }
        Log.d("TAG","request"+"\n"+requestLog);

        Response response = chain.proceed(request);
        long t2 = System.nanoTime();

        String responseLog = String.format("Received response for %s in %.1fms%n%s",
                response.request().url(), (t2 - t1) / 1e6d, response.headers());

        String bodyString = response.body().string();

        Log.d("TAG","response"+"\n"+responseLog+"\n"+bodyString);

        return response.newBuilder()
                .body(ResponseBody.create(response.body().contentType(), bodyString))
                .build();
        //return response;
    }
}

public static String bodyToString(final Request request) {
    try {
        final Request copy = request.newBuilder().build();
        final Buffer buffer = new Buffer();
        copy.body().writeTo(buffer);
        return buffer.readUtf8();
    } catch (final IOException e) {
        return "did not work";
    }
}`

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)

下面是一个拦截器，它同时记录请求和响应体(使用Timber，基于OkHttp文档中的一个例子和其他一些SO答案):

public class TimberLoggingInterceptor implements Interceptor {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();

        long t1 = System.nanoTime();
        Timber.i("Sending request %s on %s%n%s", request.url(), chain.connection(), request.headers());
        Timber.v("REQUEST BODY BEGIN\n%s\nREQUEST BODY END", bodyToString(request));

        Response response = chain.proceed(request);

        ResponseBody responseBody = response.body();
        String responseBodyString = response.body().string();

        // now we have extracted the response body but in the process
        // we have consumed the original reponse and can't read it again
        // so we need to build a new one to return from this method

        Response newResponse = response.newBuilder().body(ResponseBody.create(responseBody.contentType(), responseBodyString.getBytes())).build();

        long t2 = System.nanoTime();
        Timber.i("Received response for %s in %.1fms%n%s", response.request().url(), (t2 - t1) / 1e6d, response.headers());
        Timber.v("RESPONSE BODY BEGIN:\n%s\nRESPONSE BODY END", responseBodyString);

        return newResponse;
    }

    private static String bodyToString(final Request request){

        try {
            final Request copy = request.newBuilder().build();
            final Buffer buffer = new Buffer();
            copy.body().writeTo(buffer);
            return buffer.readUtf8();
        } catch (final IOException e) {
            return "did not work";
        }
    }
}

下面是一个使用HttpLoggingInterceptor从日志中过滤任何请求/响应参数的简单方法:

// Request patterns to filter
private static final String[] REQUEST_PATTERNS = {
    "Content-Type",
};
// Response patterns to filter
private static final String[] RESPONSE_PATTERNS = {"Server", "server", "X-Powered-By", "Set-Cookie", "Expires", "Cache-Control", "Pragma", "Content-Length", "access-control-allow-origin"};

// Log requests and response
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
    @Override
    public void log(String message) {

        // Blacklist the elements not required
        for (String pattern: REQUEST_PATTERNS) {
            if (message.startsWith(pattern)) {
                return;
            }
        }
        // Any response patterns as well...
        for (String pattern: RESPONSE_PATTERNS) {
            if (message.startsWith(pattern)) {
                return;
            }
        }
        Log.d("RETROFIT", message);
    }
});
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

这将创建一个带有Logging的改装对象。不需要创建单独的对象。

 private static final Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .client(new OkHttpClient().newBuilder()
                    .addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY))
                    .readTimeout(READ_TIMEOUT_SECONDS, TimeUnit.SECONDS)
                    .writeTimeout(WRITE_TIMEOUT_SECONDS, TimeUnit.SECONDS)
                    .connectTimeout(CONNECTION_TIMEOUT_SECONDS, TimeUnit.SECONDS)
                    .build())
            .addConverterFactory(GsonConverterFactory.create())
            .build();
