Json.decode 在 Flutter 中解析 JSON 时挂起

Question

我的回复正文包含以下数据

[{"AttendanceID":null,"MobilePrefID":"Ab12949","DateTimeInString":"08/01/2019","DateTimeOutString":"08/01/2019","TimeIn": "18:16","TimeOut":"18:18","SignInAddress":null,"SignOutAddress":null}]

解码成JSON的代码如下

var dec = json.decode(resp.body)

但是，该命令卡在这里并且不产生结果。

引用自

"Unexpected Character" on Decoding JSON

并试过你的代码

 JsonCodec codec = new JsonCodec();
  try{
    String strBody = """[{"AttendanceID":null,"MobilePrefID":"Ab12949","DateTimeInString":"08/01/2019","DateTimeOutString":"08/01/2019","TimeIn":"18:16","TimeOut":"18:18","SignInAddress":null,"SignOutAddress":null}]""";
    print(strBody);
    var decoded = codec.decode(strBody);
    print("Decoded 1: $decoded");
  } catch(e) {
    print("Error: $e");
  }

你会得到结果
