DioError [DioErrorType.RESPONSE]: Http status error [400] Exception DioError [DioErrorType.RESPONSE]: Http 状态错误 [400] 异常
Code代码
onPressed: () async {
String email_value = emailController.text;
String password_value = passController.text;
String fullname_value = fullnameController.text;
var repassword_value = repassController.text;
print("$email_value");
if (password_value == repassword_value) {
try{
Dio dio = Dio();
var body = jsonEncode(
{
'FullName': '$fullname_value',
'Email': '$email_value',
'Password': '$password_value'
}
);
print("Body" + body);
Response response = await dio.post("http://iamtv.chainuniverse.com/api/Accounts/Register",
data: body,
options: Options(
contentType: Headers.jsonContentType,
)
);
var jsonData = json.decode(response.data);
print(jsonData);
if (response.statusCode > 200 &&
response.statusCode < 250) {
print("Sucess");
await loginAction();
print("Registered");
}
else{
print(jsonData);
}
But when i send data manually without using textcontroller Text it works.但是当我在不使用 textcontroller Text 的情况下手动发送数据时,它可以工作。 Please help me to fix this请帮我解决这个问题
Late answer, may help you.迟到的答案,可能对你有帮助。
I was getting same error with Dio
and form-data
.我在使用Dio
和form-data
时遇到了同样的错误。 It worked!有效! after adding contentType
添加contentType
FormData formData = FormData.fromMap({
"image-param-name": await MultipartFile.fromFile(
imageFile.path,
filename: fileName,
contentType: new MediaType("image", "jpeg"), //add this
),
});
complete code完整代码
var dio = Dio();
String fileName = imageFile.path.split('/').last;
FormData formData = FormData.fromMap({
"image-param-name": await MultipartFile.fromFile(
imageFile.path,
filename: fileName,
contentType: new MediaType("image", "jpeg"), //add this
),
});
var response = await dio.post(
"url",
data: formData,
options: Options(
headers: {
"Authorization": auth-token
},
),
onSendProgress: (int sent, int total) {
debugPrint("sent${sent.toString()}" + " total${total.toString()}");
},
).whenComplete(() {
debugPrint("complete:");
}).catchError((onError) {
debugPrint("error:${onError.toString()}");
});
