How to get response body with request.send() in dart

Question

I'm doing an api request uploading an image with

var request = new http.MultipartRequest("POST", uri); var response = await request.send() 

in dart using flutter. I can then check the response code with for instance

if (response.statusCode == 200) {    print('ok'); } 

with other calls I can also get the response body with

var result = response.body; 

however when using request.send() I can't seem to find out how to get the response body result.

Any help or input is very much appreciated, thanks!

Answer 1

I checked the docs for request.send I returns Future<StreamedResponse> instead of Future<Response>

Digging more for StreamedResponse I found that it response.stream which is a ByteStream

Here is what you can do to get response in String

final response = await request.send(); final respStr = await response.stream.bytesToString(); 

In my opinoin you should only use request.send if you want streamed response instead of "collected" response. More about streams in dart here

Answer 2

Just use http.Response.fromStream()

import 'package:http/http.dart' as http;  var streamedResponse = await request.send() var response = await http.Response.fromStream(streamedResponse);
