改造 2.0 如何打印完整的 json 响应？

Question

我正在从 Volley 转向 Retrofit 当前版本 2.0。

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'

休息客户端：

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);

API服务：

   @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));

如果您想要漂亮的打印功能，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（不是从服务器返回的原始响应）。 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 : HttpLoggingInterceptor或拥有自己的拦截器版本
2. 使用 http 调试工具，例如Stetho 。 请参阅： http : //facebook.github.io/stetho/或Charles Web Debugging Proxy 。 见： https : //www.charlesproxy.com

Answer 2

实际上 Square 已经为此创建了一个类，只需添加

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

并且，在改造中

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）。 更多信息可在OkHttp github上获得

警告！

不要忘记在生产中删除拦截器（或将日志级别更改为 NONE）！ 否则人们将能够在 Log Cat 上看到您的请求和响应。

Answer 3

像这样插入下面的拦截器类

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 4

要在下面的改造中使用 Json 获得完整响应。

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

您可以像下面那样将setLogLevel为您的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。

setLogLevel(LogLevel.FULL)

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

首先将OkHttpLoggingInterceptor添加到您的项目中：

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()
        }

Answer 6

尝试这个 ！！

 Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    /** Handles Log */
    retrofit.client().interceptors().add(new LoggingInterceptor());

    mRestClient = retrofit.create(RestServices.class);





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

    long t1 = System.nanoTime();
    Logger.d(String.format("Sending request %s on %s%n%s",
            request.url(), chain.connection(), request.headers()));

    Response response = chain.proceed(request);

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


    final String responseString = new String(response.body().bytes());

    Logger.d("Response: " + responseString);

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

检查这个演示！！！

Answer 7

Log.e("TAG","2.0 getFeed > response.raw() => " +  new Gson().toJson(response.body()));

Answer 8

public class HttpLoggingInterceptor {
    HttpLoggingInterceptor provideHttpLoggingInterceptor(){
        return new HttpLoggingInterceptor(message ->
                Log.d("TAG", message)).setLevel(HttpLoggingInterceptor.Level.BODY);
    }
}


public class OkHttpClient {
    OkHttpClient provideOkHttpClient(@NonNull HttpLoggingInterceptor interceptor){
        return new OkHttpClient.Builder()
               .addInterceptor(interceptor)
               .build();
    }  
}

Answer 9

尝试这个 ：

 Log.d("LOG","RESPONSE ==="+response.raw().toString());

Answer 10

看看 okhttp3.logging 包，他们已经有 HttpLoggingInterceptor 可以满足您的需求。 根据它们，您还可以指定日志记录级别。

并且您可以将这个拦截器包含在您的请求中 - 通过 OkHttpClient.Builder：

public OkHttpClient provideOkHttpClient() {
    final OkHttpClient.Builder okHttpBuilder = new OkHttpClient.Builder();
    okHttpBuilder.addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY));
    return okHttpBuilder.build();
}

Answer 11

要使用改造 2.0 获得完整的 json 响应，请遵循下面给出的代码

接口

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

改造呼叫功能

Call<JsonObject> call = RestClient.get().getFeed();
    call.enqueue(new Callback<JsonObject>() {
        @Override
        public void onResponse(Call<JsonObject> call, Response<JsonObject> response) {
            Log.d("res", response.body().toString());
        }

        @Override
        public void onFailure(Call<JsonObject> call, Throwable t) {
            Log.d("error",t.getMessage());
        }
    });

Answer 12

Call<Model> call = RestClient.get().getFeed();call.enqueue(new Callbstrong




textack<Model>() {

@Override


public void onResponse(Response<Model> response, Retrofit retrofit) {


//try this 


Call<Model> call = response.body();

//  this is enough for retrieve model


}

@Override
public void onFailure(Throwable t) {

  t.printStackTrace();

        og.e("2.0 getFeed > onFailure => ", t.toString());

}

});
