Question

大家好，我一直想找出api的响应，试图获取对象列表并在调试中打印，但是我做不到，我想我缺少了一些东西

我想获取这些单词的列表，但是我不知道该怎么做？

alanin, alaunian, alnein, alnuin, eolienne, laniinae, lanny, lenaean, lenin, lenny, lennow, leonine, lewanna, linen, linene, lineny, linin, linn, linnaea, linne, linon, lionne, loanin, lunn

我正在使用Flutter和http包，也尝试了dio

这是我的代码和响应

Future<List> onBtnPress(String text) async {
  http.Response response = await http.post(url, body: body);
  return jsonDecode(response.body);

}

List _data = await onBtnPress(textController.text);
     debugPrint(_data.toList().toString());



[522, [alanin, alaunian, alnein, alnuin, eolienne, laniinae, lanny, lenaean, lenin, lenny, lennow, leonine, lewanna, linen, linene, lineny, linin, linn, linnaea, linne, linon, lionne, loanin, lunn], 373, [macoma, mecum, myokymia, mokum]]

我尝试了_data[0][index]，但它只显示5 2 2

Answer 1

使用this

创建响应模型

Future<listResponse> getList() async {
    final HttpResponse response = await this.getRequest(ApiType.getObjectList, params: {}, );
    responseList objData;
    if (response.status == 200 ) {
      objData = responseList.fromJson(response.json);
      return listResponse(status: response.status, message: response.errMessage, data: objData);
    }else{
      return listResponse(status: response.status, message: response.errMessage, data: null);
    }
  }

希望获得帮助！

Answer 2

您正在使用POST方法而不是Get。这就是为什么要获取状态码的原因。试试

Future<List> onBtnPress(String text) async { http.Response response = await http.get(url, body: body); return jsonDecode(response.body);

如果需要身份验证，请确保将其添加到标题中

Answer 3

我想通了，谢谢我得到的回应是一个列表

类似于list [0] = 522; list [1] = [asdf，adsf，asdf，]

非常感谢您

data[0] = 522

＆

data[1] = [alanin, alaunian, alnein, alnuin, eolienne, laniinae, lanny, lenaean, lenin, lenny, lennow, leonine, lewanna, linen, linene, lineny, linin, linn, linnaea, linne, linon, lionne, loanin, lunn]

Answer 4

var rawJson = '{"url":"http://blah.jpg","id":1}';
Map<String,dynamic> parsedJson   = json.decode(rawJson);
var imageModel = ImageModel(id: parsedJson['id'],url: parsedJson['url']);

class ImageModel
{ int id; String url; ImageModel({this.id,this.url});}
