Im trying to make a http-request to Filemaker with Flutter(package:http/http.dart)
I can get the token normally, but if i try the make an _find request to Filemaker it always get's rejected(400 Bad Request) without any message.
In Postman I can do the exact same request without issue!
var body = { "query":[{
"loginName": "==testUser#test.com"
}]};
Response response = await post(url,
headers: {
HttpHeaders.authorizationHeader: 'Bearer $token',
HttpHeaders.contentTypeHeader: 'application/json'},
body: json.encode(body));
Found it:
Dart http adds: content-type: application/json; charset=utf-8
And Filemaker rejects this..
But now is the question why does Filemaker API rejects such an API Call?
SOLVED.
I was able to access one user in a FileMaker layout using Dio.
Dio dio = Dio();
dio.options.headers['content-Type'] = 'application/json';
dio.options.headers["authorization"] = "Bearer ${token}";
Response recordResponse;
recordResponse = await dio.post(
findUrl,
options: Options(followRedirects: false, validateStatus: (status)
{return status < 500;}),
data: { "query":
[{
"username": "=Jake",
"password": "=password"
}]
}
);

I have an API that expects a JWT token.
I tested the API with https://hoppscotch.io, here is the query that returns the expected results (no error)
import axios from "axios";
const options = {
method: 'POST',
url: 'https://my_authority/text-message',
headers: {
Authorization: 'Bearer my_token',
'content-type': 'application/json'
},
data: {message: ''}
};
axios.request(options).then(function (response) {
console.log(response.data);
}).catch(function (error) {
console.error(error);
});
And here is the code in Dart that fires the error ClientException (Failed to parse header value):
await http.post(
Uri.parse('$_httpEndpoint/$path'),
headers: {
HttpHeaders.contentTypeHeader: 'application/json',
HttpHeaders.authorizationHeader: 'Bearer my_token',
},
body: jsonEncode(body));
Both queries have the same parameters. I have no clue about the root causes.
Here is requests.headers in locals for IOClient.send when the error fires:
_CompactLinkedCustomHashMap ({content-type: application/json; charset=utf-8, authorization: Bearer my_token})
I don't know why http adds charset=utf-8, and I didn't manage to remove it.
I looked over the internet and didn't find an answer. Most of the similar questions are related to an error in the backend, it is not the case here.
I am using Flutter 1.20.4, http 0.12.2 package and I am having an issue where my HTTP calls are successful in Postman but fail in a flutter. I came across a number of articles talking about issue with lower case HTTP headers and some older servers. I don't have that issue as I have tested postman with lower case. I have checked my bearer token on jwt.io and issuer matches the domain I am using. Any call made from flutter that uses authorization will return as "not authenticated" so it would come up with HTTP 302 (redirect to login by identity provider). Any ideas?
My code looks like this:
import 'package:http/http.dart' as http;
...
var getProfileUrl = _identityApi + '/api/profile/get'; // TODO: CHANGE THIS
var accessToken = await _secureStorage.read(key: 'bearerToken');
var response = await http.get(getProfileUrl, headers: {
HttpHeaders.contentTypeHeader: 'application/json',
HttpHeaders.acceptHeader: 'application/json',
HttpHeaders.authorizationHeader: 'Bearer $accessToken'
});
POSTMAN:
FLUTTER:
try this
import 'package:http/http.dart' as http;
...
Map<String,String> _headers={
'content-type': 'application/json',
'accept: 'application/json',
'authorization': 'Bearer $accessToken'
};
var getProfileUrl = _identityApi + '/api/profile/get'; // TODO: CHANGE THIS
var accessToken = await _secureStorage.read(key: 'bearerToken');
var response = await http.get(getProfileUrl, headers: _headers);
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.
