Duolingo – Ajax cheating

Đầu tiên gửi 1 Ajax để lấy list các Skills và các thông tin liên quan

https://www.duolingo.com/{2017-06-30}/users/{user-id}?fields=adsConfig,bio,blockedUserIds,canUseModerationTools,courses,creationDate,currentCourse,email,emailAnnouncement,emailAssignment,emailAssignmentComplete,emailClassroomJoin,emailClassroomLeave,emailComment,emailEditSuggested,emailFollow,emailPass,emailWeeklyProgressReport,emailSchoolsAnnouncement,emailStreamPost,emailVerified,emailWeeklyReport,enableMicrophone,enableSoundEffects,enableSpeaker,experiments%7Bacquisition_perimeterx_block_web,acquisition_web_save_credentials_3,courses_la_en_v1,learning_web_autoscroll_placement_test,learning_web_local_grading_v2,learning_web_placement_test_skip,midas_web_full_name_required_2,midas_web_student_plan_rerun,retention_add_more_leagues,retention_remove_streak_lingot_bonus,retention_web_juicify_soft_wall,retention_web_shorter_leaderboard,retention_web_shorter_streak_calendars,retention_web_streak_freeze_used,retention_web_streak_panel,retention_web_update_language_settings,stories_en_from_es_pt_3,web_auto_display_checkpoint_popover,web_lesson_coach_duo,web_smart_tips_apply_rules,web_smart_tips_request_rules%7D,facebookId,fromLanguage,globalAmbassadorStatus,googleId,hasPlus,id,inviteURL,joinedClassroomIds,lastStreak%7BisAvailableForRepair,length%7D,learningLanguage,lingots,location,monthlyXp,name,observedClassroomIds,optionalFeatures,persistentNotifications,picture,plusDiscounts,practiceReminderSettings,privacySettings,referralInfo,requiresParentalConsent,roles,streak,streakData%7Blength%7D,timezone,timezoneOffset,totalXp,trackingProperties,unconsumedGiftIds,username,webNotificationIds,weeklyXp,xpGains,xpGoal,zhTw,_achievements&_=1567952650160

Ajax này sẽ trả về nhiều thứ. Tuy nhiên cái quan tâm là currentCourse.skills.id

Tiếp tục là ajax lấy session cho skill tương ứng

https://www.duolingo.com/2017-06-30/sessions

Ajax này dùng POST và có data là

{"fromLanguage":"vi","learningLanguage":"en","challengeTypes":["characterIntro","characterMatch","characterSelect","completeReverseTranslation","definition","dialogue","form","freeResponse","gapFill","judge","listen","name","listenComprehension","listenTap","readComprehension","select","selectPronunciation","selectTranscription","speak","tapCloze","tapComplete","tapDescribe","translate"],"levelIndex":1,"levelSessionIndex":1,"skillId":"8b5996f5b0f1f4fb6320f1e6ac9b91b4","type":"LESSON","juicy":true,"smartTipsVersion":2}

Có thể thay skillId bằng bất kì ID nào có ở Skills trên

Ajax này trả về nhiều thứ. Những cái quan trọng là

  • challenges : Danh sách bộ câu hỏi và đáp án
  • id : ID của session này

Sau khi giải quyết hết các câu hỏi sẽ có 1 ajax mới

https://www.duolingo.com/2017-06-30/sessions/{session-id}

Sử dụng session id có từ request session ở trên

PUT này hơi khá complicated

Về cơ bản xem qua nhanh thì có thể chỉ cần thay ID ứng với session ID và keep submitting là có thể get scores 😉

Update: Tương tự cho SKILL_TEST ( Thay vì chỉ là LESSON ). SKILL_TEST cho tới 20 points thay vì chỉ 15 cho LESSON 😀
