Pass body in GET request

Question

Good morning friends. How can I spend one body in the request GET?

I have an API that does a CPF search in a PDF and returns the page it is on. In the terminal, the command is as follows:

http GET http://127.0.0.1:8000/files/processed/cpf.pdf data="123.456.789-10"

I would like to consume this API with Dart/Flutter, but I cannot pass the body in the request. I tried with the following code:

   class PdfSearch{
      
      Future catchPage(String numero) async {
      Uri uri = Uri.parse("http://127.0.0.1:8000/files/processed/cpf.pdf");
      http.Request request = http.Request("GET", uri);
      request.body = '{"data": $numero}';
      final response = request.send().asStream().first;
    
  }

}

Unsuccessful...

Endpoints GET originally should not contain body in the request, which is precisely why the method http.get() has not a parameter body. For he is simply ignored.

Future<Response> get(Uri url,{Map<String, String>? headers})

If it is necessary, this may indicate a bad design in the creation of the API. In your case, the use of queryParams:

http://127.0.0.1:8000/files/processed/cpf.pdf?cpf=12345678910

Tools that cache Apis, for example, use the url for this. Thus, it is possible to pass the data in the url using its own code.
