How to pass body data in JSON format in API calling in flutter?-CodePudding

dynamic body = {
  'doctor_availablity_done': StatusEnum.Yes.index.toString(),
  'emergency_call': emergencyCall,
  'weekends': {
    "days": selectedWeekendList.toString(),
    "time_period": {
      "morning": {
        "start_time": weekendMorningStart.value.toString(),
        "end_time": weekendMorningEnd.value.toString()
      },
      "afternoon": {
        "start_time": weekendAfternoonStart.value.toString(),
        "end_time": weekendAfternoonEnd.value.toString()
      },
      "evening": {
        "start_time": weekendEveningStart.value.toString(),
        "end_time": weekendEveningEnd.value.toString()
      },
      "night": {
        "start_time": weekendNightStart.value.toString(),
        "end_time": weekendNightStart.value.toString()
      }
    }
  }.toString(),
  'weekdays': {
    "days": selectedWeekdaysList.toString(),
    "time_period": {
      "morning": {
        "start_time": weekdaysMorningStart.value.toString(),
        "end_time": weekdaysMorningEnd.value.toString()
      },
      "afternoon": {
        "start_time": weekdaysAfternoonStart.value.toString(),
        "end_time": weekdaysAfternoonEnd.value.toString()
      },
      "evening": {
        "start_time": weekdaysEveningStart.value.toString(),
        "end_time": weekdaysEveningEnd.value.toString()
      },
      "night": {
        "start_time": weekdaysNightStart.value.toString(),
        "end_time": weekdaysNightStart.value.toString()
      }
    }
  }.toString(),
};

I want to pass this whole body content in JSON format. The above data is in string. How do I pass data in JSON. I'm trying to pass it in jsonEncode(body.toString()) but it throws error of invalid data.

CodePudding user response：

You can do this way

 var body = {};
  var weekends = {};
  var timePeriod = {};

  body["doctor_availablity_done"] = "1";
  body["emergency_call"] = "emergencyCall";

  weekends["days"] = "selectedWeekendList.toString()";
  timePeriod["morning"] = {"start_time": "ads", "end_time": "qsasds"};

  weekends["time_period"] = timePeriod;
  body["weekends"] = weekends;

  print(jsonEncode(body));

Other keys you can append. this is just sample.

CodePudding user response：

You shouldn't call toString() on weekends and weekdays, and also not on the result, so like this

dynamic body = {
  'doctor_availablity_done': StatusEnum.Yes.index.toString(),
  'emergency_call': emergencyCall,
  'weekends': {
    "days": selectedWeekendList.toString(),
    "time_period": {
      "morning": {
        "start_time": weekendMorningStart.value.toString(),
        "end_time": weekendMorningEnd.value.toString()
      },
      "afternoon": {
        "start_time": weekendAfternoonStart.value.toString(),
        "end_time": weekendAfternoonEnd.value.toString()
      },
      "evening": {
        "start_time": weekendEveningStart.value.toString(),
        "end_time": weekendEveningEnd.value.toString()
      },
      "night": {
        "start_time": weekendNightStart.value.toString(),
        "end_time": weekendNightStart.value.toString()
      }
    }
  },
  'weekdays': {
    "days": selectedWeekdaysList.toString(),
    "time_period": {
      "morning": {
        "start_time": weekdaysMorningStart.value.toString(),
        "end_time": weekdaysMorningEnd.value.toString()
      },
      "afternoon": {
        "start_time": weekdaysAfternoonStart.value.toString(),
        "end_time": weekdaysAfternoonEnd.value.toString()
      },
      "evening": {
        "start_time": weekdaysEveningStart.value.toString(),
        "end_time": weekdaysEveningEnd.value.toString()
      },
      "night": {
        "start_time": weekdaysNightStart.value.toString(),
        "end_time": weekdaysNightStart.value.toString()
      }
    }
  },
};

String json = jsonEncode(body);

CodePudding user response：

  Object data = {
         "username": userName,
         "password": password,
 };


    Uri url = Uri.parse("url");
    final response = await http.post(url, body: data);
