【中文标题】Flutter中从api获取数据时出错

【英文标题】：Error in fetching data from api in flutter

【发布时间】：2021-06-19 10:03:37

【问题描述】：

我必须从此 api 获取数据 - https://api.wazirx.com/api/v2/market-status 我收到“xmlhttprequest 错误”

我应该如何克服这个问题。

Future<void> fetchUserData() async 
  final response = await http.get(Uri.https('api.wazirx.com', '/api/v2/market-status'));
  
  if (response.statusCode == 200) 
    print(response.body);
   else 
    throw Exception("Request Rejected");
  

【参考方案1】：

试试这个。 添加标题“接受”：“应用程序/json”

Future<void> fetchUserData() async 
  final host = 'api.wazirx.com';
  final path = '/api/v2/market-status'; 
  final headers = 'Accept': 'application/json';
  final uri = Uri.https(host, path);
  final response = await http.get(uri, headers: headers);
  if (response.statusCode == 200) 
    print(response.body);
   else 
    throw Exception("Request Rejected");
