I want to make a get request with DateTime inside query parameters, but DateTime takes not that form that I want. How to fix that?
I want to set this currentDate to query parameter
final currentDate = DateFormat('yyyy-MM-ddTHH:mm:ss').format(DateTime.now().toLocal());
log(currentDate); //from=2022-12-06T16:17:46
But I get this
final data = await _apiService.getNfbByPeriod(from: currentDate, to: DateTime(2022), token: accessToken!);
// currentDate = 2022-12-06T16%3A17%3A46
// /sessions/avg-nfb-by-period?from=2022-12-06T16%3A17%3A46&to=2022-01-01+00%3A00%3A00.000
>Solution :
To fix the issue with the DateTime in the query parameters, you can try encoding the DateTime using the Uri.encodeComponent() method before passing it to the getNfbByPeriod() method. This will ensure that the DateTime is properly encoded and formatted in the query parameter.
Here is an example of how you can do that:
final currentDate = DateFormat('yyyy-MM-ddTkk:mm').format(DateTime.now().toLocal());
final encodedDate = Uri.encodeComponent(currentDate);
// Pass the encodedDate to the `getNfbByPeriod()` method
final data = await _apiService.getNfbByPeriod(from: encodedDate, to: DateTime(2022), token: accessToken!);
This should fix the issue with the DateTime in the query parameters. Let me know if you have any other questions.
To format the DateTime object as an ISO 8601 date string, you can use the DateFormat.ISO_8601 constant from the dart:core library. Here is an example of how you can do that:
final currentDate = DateFormat.ISO_8601.format(DateTime.now().toLocal());
final data = await _apiService.getNfbByPeriod(from: currentDate, to: DateTime(2022), token: accessToken!);
This will ensure that the DateTime object is formatted as an ISO 8601 date string, which should be accepted by the API.
Alternatively, if you want to use a custom date format, you can use the DateFormat class to specify the desired format. Here is an example of how you can do that:
final currentDate = DateFormat('yyyy-MM-ddTkk:mm').format(DateTime.now().toLocal());
final data = await _apiService.getNfbByPeriod(from: currentDate, to: DateTime(2022), token: accessToken!);
In this case, the DateTime object will be formatted according to the specified format (‘yyyy-MM-ddTkk:mm’), which should also be accepted by the API.
I hope this helps. Let me know if you have any other questions.
