如何在dart中使用request.send()获取响应主体 [英] How to get response body with request.send() in dart

问题描述

我正在通过api请求上传图片，

I'm doing an api request uploading an image with

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

用飞镖飞镖.然后，我可以使用

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

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

通过其他调用，我也可以使用

with other calls I can also get the response body with

var result = response.body;

但是当使用request.send()时，我似乎无法找出如何获得响应正文结果.

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

非常感谢您的帮助或投入，谢谢！

Any help or input is very much appreciated, thanks!

推荐答案

我检查了文档中的

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

进一步挖掘 StreamedResponse ，我发现它 response.stream ，它是 ByteStream

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

这是您可以获取String响应的方法

Here is what you can do to get response in String

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

在我的视觉观点中，如果要流式响应而不是已收集"响应，则仅应使用request.send.有关此处的dart流

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