我在数据库中存储了一个大约 1042 个字符的长字符串,我尝试使用 API 来检索该字符串,当我在 Postman 中运行它时,它起作用了,但是当我在 flutter 中点击请求时,应用程序突然停止并冻结了。
这是代码:
@override
Future<ResponseAPI> getPrivacyPolicy() async {
try {
Dio http = await dio();
Response response = await http.get("/setting/type", queryParameters: {
"type": 7,
});
final data = response.data;
return ResponseAPI.fromJson(data);
} on DioException catch (e) {
if (e.response?.statusCode == 403) {
return ResponseAPI(
message: e.response?.data['message'],
statusCode: 403,
);
} else {
return const ResponseAPI(
message: "There's something wrong, please try again later",
statusCode: 500,
);
}
} catch (e) {
return const ResponseAPI(
message: "There's something wrong, please try again later",
statusCode: 500,
);
}
}
这是 Postman 中的回复:
尝试为 Dio 请求选项定义responseType
options: Options(
method: 'GET',
responseType: ResponseType.plain,
),
此外,检查运行时环境中是否抛出任何异常或使用 try 和 catch
