使用翻新2进行记录

本文翻译自：[Logging with Retrofit 2][]

*I'm trying to get the exact JSON that is being sent in the request.* **我正在尝试获取在请求中发送的确切JSON。** *Here is my code:* **这是我的代码：**

OkHttpClient client = new OkHttpClient(); client.interceptors().add(new Interceptor(){ @Override public com.squareup.okhttp.Response intercept(Chain chain) throws IOException { Request request = chain.request(); Log.e(String.format("\nrequest:\n%s\nheaders:\n%s", request.body().toString(), request.headers())); com.squareup.okhttp.Response response = chain.proceed(request); return response; } }); Retrofit retrofit = new Retrofit.Builder() .baseUrl(API_URL) .addConverterFactory(GsonConverterFactory.create()) .client(client).build();

*But I only see this in the logs:* **但是我只在日志中看到：**

request:
    com.squareup.okhttp.RequestBody$1@3ff4074d
    headers:
    Content-Type: application/vnd.ll.event.list+json

*How am I supposed to do proper logging, given the removal of `setLog()` and `setLogLevel()` which we used to use with Retrofit 1?* **考虑到我们曾经使用过Retrofit 1的`setLog()`和`setLogLevel()` ，我应该如何做正确的日志记录？**

*hey guys，i already find solution:* **大家好，我已经找到解决方法了：**

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);
    }

*I don't know if setLogLevel() will return in the final 2.0 version of Retrofit but for now you can use an interceptor for logging.* **我不知道setLogLevel（）是否会在Retrofit的最终2.0版本中返回，但是现在您可以使用拦截器进行记录了。**

*A good example can found in OkHttp wiki: [https://github.com/square/okhttp/wiki/Interceptors][https_github.com_square_okhttp_wiki_Interceptors]* **可以在OkHttp Wiki中找到一个很好的例子： [https][https_github.com_square_okhttp_wiki_Interceptors] : [//github.com/square/okhttp/wiki/Interceptors][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();

*Try this:* **尝试这个：**

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

*After this, in the `body` there is the JSON you are interested in.* **之后，在`body`中便是您感兴趣的JSON。**

*Here is an `Interceptor` that logs both the request and response bodies (using Timber, based on an example from the OkHttp docs and some other SO answers):* **这是一个记录请求和响应正文的`Interceptor` （使用Timber，基于OkHttp文档的示例以及其他一些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";
            }
        }
    }

*For those who need high level logging in Retrofit, use the interceptor like this* **对于需要在Retrofit中进行高级日志记录的用户，请使用此类拦截器**

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";
        }
    }`
