Flutter POST请求正文未发送 [英] Flutter POST request body not sent

问题描述

我想用以下代码在Flutter中发出发帖请求：

I want to make a post request in Flutter with the following code:

// Body: {"email": "[e-mail]", "pass": "passw0rd"}

Future<dynamic> post(String url, var body) async {
  var response = await http.post(url, body: body);
  final String res = response.body;
  return res;
}

// That's not the full code. I removed some lines because they are useless for this thread.
// Most of them are only some debug outputs or conditional statements

问题是我的发帖请求中不包含正文。我检查了服务器上的一些输出。

The problem is that my post request doesn't include the body with my request. I checked that with some outputs on my server.

推荐答案

您只需要在发送之前对主体进行编码：

You just have to encode the body before sending:

import 'dart:convert';
...

var bodyEncoded = json.encode(body);
var response = await http.post(url, body: bodyEncoded , headers: {
  "Accept": "application/json"
},);
