[ghozay19]

hi !

when im using dio post,
the post was successfull and the data was saved on the db.

but i check the logs, and got error code

DioError [DioErrorType.RESPONSE]: Http status error [302]

here's my code

_submit() async {    
var url =
        "https://script.google.com/macros/s/AKfycbyZMw-4aNli_vfIucxNxAZvIfWOtWlQEBST8EtDh4zGcDnEHCA7/exec?";

    try {
      var dio = new Dio();
      var response = await dio.post(
        url,
        queryParameters: {
          'action': 'insert',
          'tableName': 'presensi',
          'nis': nis,
          'nama': nama,
          'status': status
        },
        options: Options(
          connectTimeout: 5000,
          receiveTimeout: 10000,
        ),
      );

      print(response.toString());
    } on DioError catch (error) {
      if (error.response.statusCode == 302) {
        print("nani kore ? : " + error.toString());
      }
    }

note :
post was success but logs show 302.
how to resolve 302 code?

302 is the status code for a redirect.
I face the kind a same issue. My POST request to log in is awnserd with a 302 response. But i'm not sure wether the responded cockie is saved to the cockie jar.
The followup requests fail cause the cockie is not present.

i have a same question too

[2x2xplz]

I have the same concern as @zaubererty regarding cookies. Dio makes a POST request and receives a 302 response with a Set-Cookie header. However the redirected request does not appear to include the new cookie. I'm using the default CookieJar plugin with a PersistentCookieJar.

Add followRedirects: false and validateStatus: (status) { return status < 500;} to the request

var response = await Dio().post("http://myurl",
data: requestBody,
options: Options(
followRedirects: false,
validateStatus: (status) { return status < 500; }
),
);

Thanks @alfawzaan
I'd suggest return status < 400; , as you probably want 404 not found , 401 unauthorized , etc to still raise errors. Also keep in mind if you aren't following redirects you'll need a manual way to send Dio to the relocated page, perhaps by reading the Location header
