I am using the flutter http package. Is there a way to send cookies without using header? To be clear below is an example of doing so using curl:
curl --cookie "auth_session=abcd" http://127.0.0.1:9011/api/v1/login
Also, I'm using flutter for both web and mobile. Therefore, the io-library-based solutions are not applicable to web. Like this one which is not even using the http package.
Currently, I'm using http package like so:
final String uri = "www.example.com";
final response = await post(
Uri.parse(uri),
headers: <String, String>{
'Content-Type': 'application/json; charset=UTF-8',
'Cookie': 'sessionid=asdasdasqqwd' // Don't want to use header
},
body: body),
);
Thanks in advance.

Currently my server has already setup the proxy, when i wanted to call external api it will be block, so right now i want to call the api https://www.google.com/recaptcha/api/siteverify to implement captcha to my project
final response = await http.post(
Config.verificationURL,
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Access-Control-Allow-Origin': '*'
},
body: 'secret=${Config.secretKey}&response=$_token',
);
any idea on how to convert this api call via proxy for flutter?
I am using http client for flutter network call.
My request working on postman getting response properly,
But while trying with http.post it returns error code 307-Temporary Redirect,
Method Body:
static Future<http.Response> httpPost(
Map postParam, String serviceURL) async {
Map tempParam = {"id": "username", "pwd": "password"};
var param = json.encode(tempParam);
serviceURL = "http:xxxx/Login/Login";
// temp check
Map<String, String> headers = {
'Content-Type': 'application/json',
'cache-control': 'no-cache',
};
await http.post(serviceURL, headers: headers, body: param).then((response) {
return response;
});
}
Also, the same code returns a proper response to other requests and URLs.
First I trying with chopper client but had same issue.
I am unable to detect that issue from my end of from server-side.
Any help/hint will be helpful
Try to put a slash / at the end of the serviceUrl. So, serviceUrl is serviceURL = "http:xxxx/Login/Login/" instead of serviceURL = "http:xxxx/Login/Login".
This works for me.
You need to find a way to follow redirect.
Maybe postman is doing that.
Read this >>
https://api.flutter.dev/flutter/dart-io/HttpClientRequest/followRedirects.html
Can you try with using get instead of post? At least to try and see what happend
In the documentation said:
Automatic redirect will only happen for "GET" and "HEAD" requests
only for the status codes
HttpStatus.movedPermanently (301),
HttpStatus.found (302),
HttpStatus.movedTemporarily (302, alias for HttpStatus.found),
HttpStatus.seeOther (303),
HttpStatus.temporaryRedirect (307)
keeping https instead of http in the URL it is helping me.
#Abel's answer above is correct but I had to switch from using:
Uri url = Uri.https(defaultUri, path);
to
Uri url = Uri.parse('https://todo-fastapi-flutter.herokuapp.com/plan/');
to get that last / after plan.
The first way kept dropping it so I was getting 307 errors.
flutter.dev shows a full example:
Future<http.Response> createAlbum(String title) {
return http.post(
Uri.parse('https://jsonplaceholder.typicode.com/albums'),
headers: <String, String>{
'Content-Type': 'application/json; charset=UTF-8',
},
body: jsonEncode(<String, String>{
'title': title,
}),
);
}
here: https://flutter.dev/docs/cookbook/networking/send-data#2-sending-data-to-server
For Dio Http Client, use Dio Option follow redirect as True
getDioOption(){
return BaseOptions(connectTimeout: 30, receiveTimeout: 30,
followRedirects: true);
}
I am making a flutter application, and i have written a server in django. When i send a token to my server for authentication then my server sends me an error of undefined token. Without token all requests works fine, but when i add a token then it gives me an error
{detail: Authentication credentials were not provided.}
But When i add token in modheader, my server works fine
Authorization: Token bff0e7675d6d80bd692f1be811da63e4182e4a5f
This is my flutter code
const url = 'MY_API_URL';
var authorization = 'Token bff0e7675d6d80bd692f1be811da63e4182e4a5f';
final response = await http.get(
url,
headers: {
'Content-Type': 'application/json',
'Authorization': authorization,
}
);
final responseData = json.decode(response.body);
print('responseData');
print(responseData);
try this:
Map<String, String> headers = {
HttpHeaders.contentTypeHeader: 'application/json',
HttpHeaders.acceptHeader: 'application/json',
HttpHeaders.authorizationHeader: 'Token bff0e7675d6d80bd692f1be811da63e4182e4a5f'
};
& use them in request
final response = await http.get(
url,
headers: headers,
);
As I don't know to work on your API so I can't tell you the exact answer.
Check that, Is your backend taking authorization by header or body or
I'll suggest you first make authorization by tools like postman then
if that succeeds then try to implement that in your app.
I am trying to send a http request using the http plugin on version ^0.12.0+4 (the latest one).
http.Response response = await http.post(
http://localhost:8085,
body: jsonEncode({"test": "test"}),
headers: {
"accept": "application/json",
"content-type": "application/json"
},
);
I have a SpringBoot backend running which stated, that the request body is empty. Debug attempts with Postman worked fine.
I tried the Dio package as well with the same result.
I was trying to make a call to a REST service using the Dio plugin, but kept getting HTTP 400 response code. I thought I was doing everything right by setting the content type and response type options to JSON:
Response response = await Dio().get(
'https://api.example.com/v1/products/$productId',
queryParameters: {},
options: Options(
contentType: ContentType.json,
responseType: ResponseType.json,
headers: {'Authorization': 'Bearer $MY_API_KEY'}
),
);
However, it turns out that I needed to add a Content-Type header as well:
headers: {'Authorization': 'Bearer $MY_API_KEY'}, 'Content-Type': 'application/json' };
So now I'm confused - what exactly does the contentType option do? I thought it was analogous to setting the Content-Type header manually?
I've tried this locally using dio: ^3.0.10 and it seems that ContentType.json is an invalid value for contentType.
Digging through the documentation for dio, Headers.jsonContentType should be used.
