如何使用 Retrofit 查看创建的 JSON 字符串

Question

我不确定这是否是一个愚蠢的问题（因此我无法找到答案），但我想知道是否可以 Toast 或 Log 输出正在发送到服务器的创建的 JSON，当它已发送。

我只是想查看创建的 JSON - 我正在使用以下方法，即使用 Retrofit 和 .addConverterFactory(GsonConverterFactory.create(gson))：

private void addTeamMember(final List teamMemberArray,final String team_id) {

    //helps with debugging regarding post requests
    Gson gson = new GsonBuilder()
            .setLenient()
            .create();


    //Retrofit is a REST Client for Android and Java by Square.
    //It makes it relatively easy to retrieve and upload JSON (or other structured data) via a REST based webservice
    Retrofit retrofit = new Retrofit.Builder()
            //directing to the localhost which is defined in the Constants Class as BASE_URL
            .baseUrl(Constants.BASE_URL)
            //Add converter factory for serialization and deserialization of objects.
            //Gson passed as a parameter to help with debug
            .addConverterFactory(GsonConverterFactory.create(gson))
            //Create the Retrofit instance using the configured values.
            .build();



    //The Retrofit class generates an implementation of the RequestInterface interface.
    RequestInterface requestInterface = retrofit.create(RequestInterface.class);



    for (Object x : teamMemberArray) {


        //create new Team object
        TeamMember teamMember = new TeamMember();


        //setter
        teamMember.setFullName(String.valueOf(x));
        teamMember.setTeam_id(team_id);

        Toast.makeText(getActivity(), teamMember.getFullName(),
                Toast.LENGTH_LONG).show();


        //create new server object
        final ServerRequest request = new ServerRequest();


        //make a request to set the operation to Team_Member
        request.setOperation(Constants.Team_Member);
        //set values entered for the new teamMember to be sent to the server
        request.setTeamMember(teamMember);


        Call<ServerResponse> response = requestInterface.operation(request);


        /**
         * Enqueue is used to Asynchronously send the request and notify callback of its response or if an error occurred
         * talking to the server, creating the request, or processing the response.
         */


        response.enqueue(new Callback<ServerResponse>() {

            @Override
            public void onResponse(Call<ServerResponse> call, retrofit2.Response<ServerResponse> response) {

                ServerResponse resp = response.body();


            /*Snackbars provide lightweight feedback about an operation. They show a brief message at the
            bottom of the screen on mobile and lower left on larger devices. Snackbars appear above all other
            elements on screen and only one can be displayed at a time.
             */


                Snackbar.make(getView(), resp.getMessage(), Snackbar.LENGTH_LONG).show();


                if (resp.getResult().equals(Constants.SUCCESS)) {
                    SharedPreferences.Editor editor = pref.edit();


                    Log.d("TEST VALUE", "getTeamMemberName() = " + response.body().getTeamMember().getFullName() );
                    Log.d("TEST VALUE", "getTeamMemberUniqueID() = " + response.body().getTeamMember().getUnique_id());
                    Log.d("TEST VALUE", "getTeamMemberTeamID() = " + response.body().getTeamMember().getTeamID());

                          editor.putString(Constants.FULL_NAME, resp.getTeamMember().getFullName());
                          editor.putString(Constants.UNIQUE_ID, resp.getTeamMember().getUnique_id());
                          editor.putString(Constants.TEAM_ID, resp.getTeamMember().getTeamID());
                          editor.apply();
                          goToQuestions();

                }

                progress.setVisibility(View.INVISIBLE);

            }

            @Override
            public void onFailure(Call<ServerResponse> call, Throwable t) {

                progress.setVisibility(View.INVISIBLE);
                Log.d(Constants.TAG, "failed" + t);
                Snackbar.make(getView(), t.getLocalizedMessage(), Snackbar.LENGTH_LONG).show();


            }
        });
    }

}

我的理由是，如果我可以看到发送的 JSON，它将帮助我在使用 Postman 时进行调试。

Answer 1

您可以使用OkHttpInterceptor 通过Retrofit 记录网络调用。它将拦截任何呼叫并在记录器中显示日志。

在你的 gradle 中添加依赖：

 compile 'com.squareup.okhttp3:logging-interceptor:3.8.0'

然后在设置您的改造客户端之前使用：

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(Level.BASIC);
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(logging)
  .build();

最后添加改造：

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

Answer 2

将此添加到dependencies

compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'

和 ApiClient

    public class ApiClient {


    public static final String BASE_URL = "URL";
    private static Retrofit retrofit = null;



    public static Retrofit getClient() {

        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);


        final OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .readTimeout(300, TimeUnit.SECONDS)
                .connectTimeout(300, TimeUnit.SECONDS)
                .addInterceptor(logging)
                .build();


        if (retrofit == null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .client(okHttpClient)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return retrofit;
    }

}
