Question

我是Java新手。我正在我的json字符串中进行一些串联工作。

   String JSONstring = {"page_1":"{\"city\":\"Delhi\",\"locality\":\"Alaknanda\",\"Name_of_Person\":\"Varun Patil\",\"User_email_address\":\"varun.vap@gmail.com\",\"user_phone_number\":\"\",\"sub_locality\":\"\",\"street_name\":\"Pune\",\"home_plot_no\":\"xyz\",\"pin_code\":\"411060\",\"project_society_build_name\":\"\",\"landmark_reference_1\":\"\",\"landmark_reference_2\":\"\",\"No_of_Schools\":20,\"No_of_Hospitals\":20,\"No_of_Metro\":0,\"No_of_Mall\":20,\"No_of_Park\":20,\"Distance_of_schools\":1.51,\"Distance_of_Hospitals\":2.5,\"Distance_of_Metro\":0,\"Distance_of_Mall\":1.9,\"Distance_of_Park\":1.1,\"lat\":28.5304408,\"lng\":77.2505733,\"ipinfo\":{\"ip\":\"59.88.97.45\",\"hostname\":\"No Hostname\",\"city\":\"Pune\",\"region\":\"Maharashtra\",\"country\":\"IN\",\"loc\":\"18.5333,73.8667\",\"org\":\"AS9829 National Internet Backbone\",\"postal\":\"411001\"}}","page_2":"{\"home_type\":\"Flat\",\"area\":\"1000\",\"beds\":\"2 BHK\",\"bath_rooms\":2,\"building_age\":\"3\",\"floors\":\"\",\"balcony\":1,\"amenities\":\"regular\",\"amenities_options\":{\"gated_security\":\"\",\"physical_security\":\"\",\"cctv_camera\":\"\",\"controll_access\":\"\",\"elevator\":\"\",\"power_back_up\":\"\",\"parking\":\"\",\"partial_parking\":\"\",\"onsite_maintenance_store\":\"\",\"open_garden\":\"\",\"party_lawn\":\"\",\"amenities_balcony\":\"\",\"club_house\":\"\",\"fitness_center\":\"\",\"swimming_pool\":\"\",\"party_hall\":\"\",\"tennis_court\":\"\",\"basket_ball_court\":\"\",\"squash_coutry\":\"\",\"amphi_theatre\":\"\",\"business_center\":\"\",\"jogging_track\":\"\",\"convinience_store\":\"\",\"guest_rooms\":\"\"},\"interior\":\"regular\",\"interior_options\":{\"tiles\":\"\",\"marble\":\"\",\"wooden\":\"\",\"modular_kitchen\":\"\",\"partial_modular_kitchen\":\"\",\"gas_pipe\":\"\",\"intercom_system\":\"\",\"air_conditioning\":\"\",\"partial_air_conditioning\":\"\",\"wardrobe\":\"\",\"sanitation_fixtures\":\"\",\"false_ceiling\":\"\",\"partial_false_ceiling\":\"\",\"recessed_lighting\":\"\"},\"location\":\"regular\",\"location_options\":{\"good_view\":\"\",\"transporation_hub\":\"\",\"shopping_center\":\"\",\"hospital\":\"\",\"school\":\"\",\"ample_parking\":\"\",\"park\":\"\",\"temple\":\"\",\"bank\":\"\",\"less_congestion\":\"\",\"less_pollution\":\"\"},\"maintenance\":\"\",\"maintenance_value\":\"\",\"near_by\":{\"school\":\"\",\"hospital\":\"\",\"mall\":\"\",\"park\":\"\",\"metro\":\"\"},\"city\":\"Delhi\",\"locality\":\"Alaknanda\",\"token\":\"9a2a8bf359494054f98c80009b5bd0e7\"}"}
    // removing slashes in JSON input
    String jsonFormattedString = JSONString.replaceAll("\\\\", "");
    // // removing quote next to the city column
    String city_column = replaceCharAt(jsonFormattedString, 10, "");
    // // removing quotes at start and end of the inputs
    String quote_end = city_column.replaceAll("^\"|\"$", "");
    // // removing quote next to page_2
    String remove_brace = quote_end.replace("page_2\":\"", "page_2\":");
    // // appending braces at the end of the line
    String append_brace = remove_brace.replace("}}\"", "}}");
    String input = append_brace.substring(0, append_brace.length() - 2);
    String final_input = input.concat("}");

    JSONObject obj = new JSONObject(final_input);

是否有任何功能可以执行此操作以进行代码优化？

Answer 1

第一行是无效的Java语句，但假设您只是显示要解析的字符串值，它是一个有效的JSON字符串。

如果您将字符串解析为JSON，您将获得一个包含2个值的JSON对象：page_1和page_2。

如果您提取page_1的值，您将获得以下字符串：

{"city":"Delhi","locality":"Alaknanda","Name_of_Person":"Varun Patil","User_email_address":"varun.vap@gmail.com","user_phone_number":"","sub_locality":"","street_name":"Pune","home_plot_no":"xyz","pin_code":"411060","project_society_build_name":"","landmark_reference_1":"","landmark_reference_2":"","No_of_Schools":20,"No_of_Hospitals":20,"No_of_Metro":0,"No_of_Mall":20,"No_of_Park":20,"Distance_of_schools":1.51,"Distance_of_Hospitals":2.5,"Distance_of_Metro":0,"Distance_of_Mall":1.9,"Distance_of_Park":1.1,"lat":28.5304408,"lng":77.2505733,"ipinfo":{"ip":"59.88.97.45","hostname":"No Hostname","city":"Pune","region":"Maharashtra","country":"IN","loc":"18.5333,73.8667","org":"AS9829 National Internet Backbone","postal":"411001"}}

如果然后将其解析为JSON，您将获得一个JSON对象，其格式如下：

{
   "city":"Delhi",
   "locality":"Alaknanda",
   "Name_of_Person":"Varun Patil",
   "User_email_address":"varun.vap@gmail.com",
   "user_phone_number":"",
   "sub_locality":"",
   "street_name":"Pune",
   "home_plot_no":"xyz",
   "pin_code":"411060",
   "project_society_build_name":"",
   "landmark_reference_1":"",
   "landmark_reference_2":"",
   "No_of_Schools":20,
   "No_of_Hospitals":20,
   "No_of_Metro":0,
   "No_of_Mall":20,
   "No_of_Park":20,
   "Distance_of_schools":1.51,
   "Distance_of_Hospitals":2.5,
   "Distance_of_Metro":0,
   "Distance_of_Mall":1.9,
   "Distance_of_Park":1.1,
   "lat":28.5304408,
   "lng":77.2505733,
   "ipinfo":{
      "ip":"59.88.97.45",
      "hostname":"No Hostname",
      "city":"Pune",
      "region":"Maharashtra",
      "country":"IN",
      "loc":"18.5333,73.8667",
      "org":"AS9829 National Internet Backbone",
      "postal":"411001"
   }
}

同样，您也可以解析page_2。

的值

所以，你所要做的就是对原始输入进行双重解析。
