试试这个:

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

在此之后，在正文中有您感兴趣的JSON。

在改装2中，你应该使用HttpLoggingInterceptor。

向build.gradle添加依赖项。截至2019年10月的最新版本为:

implementation 'com.squareup.okhttp3:logging-interceptor:4.2.1'

创建一个Retrofit对象，如下所示:

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://backend.example.com")
        .client(client)
        .addConverterFactory(GsonConverterFactory.create())
        .build();

return retrofit.create(ApiClient.class);

如果出现弃用警告，只需将setLevel更改为:

interceptor.level(HttpLoggingInterceptor.Level.BODY);

上面的解决方案为您提供的logcat消息非常类似于

setLogLevel(RestAdapter.LogLevel.FULL)

对于java.lang.ClassNotFoundException:

旧的Retrofit版本可能需要旧的日志拦截器版本。详情请看评论部分。

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();

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();
        }

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";
    }
}`

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());
