如何将这种查询参数添加到 Dart http 请求中？

Question

How do you correctly add this kind of query parameters to a Dart http get request. This is my code

String? token;
  String? baseUrl = 'vps';
  String? path = 'web/session';

Map<String, dynamic> query ={
      "jsonrpc": "1.0",
      "method": "call",
      "id": "2",
      "params": {
        "login": username,
        "password": password,
        "db": "dev.sf.com",
        "context": {}
      }
    };

Uri uri = Uri.http(baseUrl.toString(), '$path/$endPath');
    if (query != null) {
      uri = Uri.http(baseUrl.toString(), '$path/$endPath', query);
    }
    return http.get(uri, headers: {
      'Authorization': 'Bearer $token',
      'Accept': 'application/json',
    });

but i get this error

 [ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: type '_InternalLinkedHashMap<String, Object>' is not a subtype of type 'Iterable<dynamic>'

Try to send primitive types like int, string, boolean, etc. You send a Map as "params", this shouldnt work.

Map<String, dynamic> query ={
      "jsonrpc": "1.0",
      "method": "call",
      "id": "2",
      "login": username,
      "password": password,
      "db": "dev.sf.com",
    };

Alternative (and better imo): Make a post request and send it inside the body.
