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";
        }
    }
}

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();

在java.lang.ClassNotFoundException的情况下使用dagger

我删除了

implementation("com.squareup.okhttp3:okhttp:4.9.0")

一切都很正常。

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";
    }
}`

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();

试试这个:

Request request = chain.request();
Buffer buffer = new Buffer();
request.body().writeTo(buffer);
String body = buffer.readUtf8();
