我是Flutter的新手。我正在进行POST API调用,并且期望在其中收到类似{“ status”:“ Saved”}之类的响应,因为我在Postman中得到了正确的信息,但是我遇到了未处理的异常:FormatException:输入的意外结束(字符1)在我的颤动代码中。我在堆栈溢出时检查了类似的问题和答案,但没有一个对我有帮助。
static Future<SaveLocationData> saveLocation(BuildContext context, String url,
{Map body}) async {
print("save location pressed $body");
Map<String, String> requestHeaders = {
'Content-type': 'application/json',
'Accept': 'application/json',
};
try {
return post(url, body: jsonEncode(body), headers: requestHeaders)
.then((response) {
print("DATA ${response.body}");
var parsedJson = json.decode(response.body.toString());
NormalAlert.showAlert(
context,
"${parsedJson['status'].toString().replaceAll("\n", " ")}",
"Save Location");
final int statusCode = response.statusCode;
if (statusCode < 200 || statusCode > 400 || json == null) {
throw new Exception("Error while fetching data");
}
return SaveLocationData.fromJson(json.decode(response.body));
});
} catch (error) {
print("erroris $error");
}
}
