改造2.0如何打印完整的json响应？

Question

我现在从Volley转到Retrofit 2.0版本.

如何打印完整的json响应代码？

包括:

compile 'com.squareup.retrofit:converter-gson:2.0.0-beta2'
compile 'com.squareup.retrofit:retrofit:2.0.0-beta2'

RestClient:

OkHttpClient client = new OkHttpClient();
        client.interceptors().add(new Interceptor() {
            @Override
            public Response intercept(Interceptor.Chain chain) throws IOException {
                Response response = chain.proceed(chain.request());                
                return response;
            }
        });


        Gson gson = new GsonBuilder()
                .setDateFormat("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'SSS'Z'")
                .create();


        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(ROOT)
                .addConverterFactory(GsonConverterFactory.create(gson))
                .client(client)
                .build();

        REST_CLIENT = retrofit.create(APIService.class);

APIService:

   @GET("my/json")
    Call<Model> getFeed();

在活动中 - 调用API:

Call<Model> call = RestClient.get().getFeed();
call.enqueue(new Callback<Model>() {
    @Override
    public void onResponse(Response<Model> response, Retrofit retrofit) {

        Log.w("2.0 getFeed > response.raw() => ", response.raw().toString());//DONT WORK
        Log.w("2.0 getFeed > retrofit => ", retrofit.toString());//DONT WORK
        Log.w("2.0 getFeed > body => ", response.body().toString()); //DONT WORK
        Log.w("2.0 getFeed > getStatus => ", response.body().getStatus());

    }

    @Override
    public void onFailure(Throwable t) {
        t.printStackTrace();
        Log.e("2.0 getFeed > onFailure => ", t.toString());
    }
});

Answer 1

要在json中打印完整的响应:

Log.w("2.0 getFeed > Full json res wrapped in gson => ",new Gson().toJson(response));

如果您想拥有漂亮的打印功能,请使用:

Log.w("2.0 getFeed > Full json res wrapped in pretty printed gson => ",new GsonBuilder().setPrettyPrinting().create().toJson(response));

请注意,这会打印反序列化的数据(而不是从服务器返回的Raw响应).要获得原始响应,您可以使用以下方法之一:

1. 使用HttpLoggingInterceptor请参阅:https://stackoverflow.com/a/33256827/2267723或拥有自己的拦截器版本
2. 使用http调试工具等Stetho.见:http://facebook.github.io/stetho/或Charles Web Debugging Proxy.请参阅:https://www.charlesproxy.com

Answer 2

像这样插入以下拦截器类

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

//////拦截器类

public static class LoggingInterceptor implements Interceptor {
        @Override
        public com.squareup.okhttp.Response intercept(Chain chain) throws IOException {
            Log.i("LoggingInterceptor","inside intercept callback");
            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());
            if(request.method().compareToIgnoreCase("post")==0){
                requestLog ="\n"+requestLog+"\n"+bodyToString(request);
            }
            Log.d("TAG","request"+"\n"+requestLog);
            com.squareup.okhttp.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 only"+"\n"+bodyString);

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

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

        }


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";
    }
}`

Answer 3

实际上Square已经为此创建了一个类,只需添加即可

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

而且,在Retrofit中

Retrofit retrofit = new Retrofit.Builder()
            .client(client)               
            .baseUrl("https://yourapi.com/api/")
            .build();

拦截器类位于maven中心

compile 'com.squareup.okhttp3:logging-interceptor:3.5.0'

您可以在HttpLoggingInterceptor类中设置日志记录级别.BODY是冗长的(它将所有内容打印到Body).有关更多信息,请访问OkHttp github

警告!

不要忘记在生产中删除拦截器(或将记录级别更改为NONE)!否则,人们将能够在Log Cat上看到您的请求和响应.

Answer 4

要在Retrofit2.3.0中获得Json的完整响应，请使用以下内容。

这对我有用。

call.enqueue(new Callback<someList>() {
        @Override
        public void onResponse(Call<someList> call, Response<someList> response) {
            if (response.isSuccessful())
                Log.e("Success", new Gson().toJson(response.body()));
            else
                Log.e("unSuccess", new Gson().toJson(response.errorBody()));
        }

        @Override
        public void onFailure(Call<someList> call, Throwable t) {
            Log.e("onFailure", t.toString());
        }
    });

Answer 5

您可以像下面一样setLogLevel访问您的Retrofit适配器，并查看响应和其他数据，例如标头、响应代码与响应代码。

setLogLevel(LogLevel.FULL)

如果您使用的是 Retrofit 版本 2+，则必须设置OkHttpLoggingInterceptor为查看日志。

首先添加OkHttpLoggingInterceptor到您的项目中：

com.squareup.okhttp3:logging-interceptor:${Versions.okHttpLoggingInterceptorVersion}

然后创建 init 你的拦截器：

HttpLoggingInterceptor().apply { level = HttpLoggingInterceptor.Level.BODY }

最后将其添加到您的 OkHttpClient

with(OkHttpClient.Builder()) {
            if (BuildConfig.DEBUG) addInterceptor(loggingInterceptor)
            build()
        }
