How to put raw data in a http get request in Flutter(Dart)? - flutter

Question

I'm trying to execute the following curl in dart but I can't find a way to achieve that:
curl --location --request GET 'https://someurl.com/query' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer xxxx' \
--data-raw '{
"query":"test_value",
"size":10
}'
The only way I've found to achieve this is to use POST and put the raw data inside the body but I was wondering if there is a real way to achieve that since the POST request with a body seems to be about 220ms slower than the GET one(I know that they should be almost equal, it may be something from the server when recieving the request).

Answer 1

The default get() method of the http package doesn't allow you to add data since that isn't a common thing to do. You can get around this by using the Request object directly for more fine-grained control, as stated in the docs:
Request req = Request('GET', Uri.parse('https://someurl.com/query'))
..body = json.encode(data)
..headers.addAll({
"Content-type": "application/json",
"Authorization": "Bearer xxxx"
});
var response await req.send();
if (response.statusCode == 200) {
// do something with valid response
}
I'd look at getting the POST variant working properly, since a GET method semantically shouldn't do anything with the provided body. But that's a different discussion of course.

Answer 2

import 'package:http/http.dart' as http;
// Define the raw data to be sent in the request
String rawData = '{ "key": "value" }';
// Send the GET request with the raw data as the body
http.Response response = await http.get(
'https://example.com/endpoint',
headers: {'Content-Type': 'application/json'},
body: rawData,
);
// Check the status code of the response to see if the request was successful
if (response.statusCode == 200) {
// The request was successful, process the response
} else {
// The request was not successful, handle the error
}
