How to make API call in flutter with header key? - flutter

Question

Suppose the host site is: :
https://dev.xyz.com
API header key: "x-api-key: 7462-3172-8773-3312-5819"
To register a new user you have to call PUT method: {{host}}/api/customer/
And the body is like this:
{"email": "test#example.net",
"password": "aabbccdd",
"Name": "John",
}
Now how do I accomplish this in flutter? I have searched through several tutorials and still in confusion.

Answer 1

Import the http package from dart library and alias it as http, reason for this aliasing is that you dont want to have .get() method suggestion everywhere in the file. So when you use it with http as http.get() it will give you suggestion for get, In which you can pass the parameter called headers.
Code goes as follows:
import 'package:http/http.dart' as http;
url = 'YOUR_URL';
var response = await http.get(
url,
headers: {HttpHeaders.authorizationHeader: TOKEN}, //an example header
);
In your case,
import 'dart:convert';
import 'dart:io';
import 'dart:async';
main() async {
String url =
'https://dev.xyz.com';
Map map = {
'data': {'apikey': '7462-3172-8773-3312-5819'},
};
print(await apiRequest(url, map));
}
Future<String> apiRequest(String url, Map jsonMap) async {
HttpClient httpClient = new HttpClient();
HttpClientRequest request = await httpClient.postUrl(Uri.parse(url));
request.headers.set('content-type', 'application/json');
request.add(utf8.encode(json.encode(jsonMap)));
HttpClientResponse response = await request.close();
// todo - you should check the response.statusCode
String reply = await response.transform(utf8.decoder).join();
httpClient.close();
return reply;
}

You need put the header on the http request. For example:
await put(urlApi + 'update/'+ customer.id, headers: {'token': token, 'content-type': 'application/json'},body: body);
