Flutter如何发布JSON数组 [英] Flutter how to post json array

问题描述

如何在json数组下面发布内容?

How to post below json array?

"LstUserOptions": [
  {
    "OptionID": "ca339e40-10cc-4459-b9ec-07f7df0f4c69"
  }
]

推荐答案

我找到了解决方案:

List<Map> carOptionJson = new List();
CarJson carJson = new CarJson("ca339e40-10cc-4459-b9ec-07f7df0f4c69");
carOptionJson.add(carJson.TojsonData());

var body = json.encode({
  "LstUserOptions": carOptionJson
});

http.Response response = await http.post(
    Uri.encodeFull(ConfigApi.SAVE),
    body: body,
    headers: {'Content-type': 'application/json'});

class CarJson {
  String OptionID;
  CarJson(this.OptionID);
  Map<String, dynamic> TojsonData() {
    var map = new Map<String, dynamic>();
    map["OptionID"] = OptionID;
    return map;
  }
}
