这是我向 API 发出请求的代码:
import 'dart:async';
import 'dart:convert';
import 'dart:io';
import 'package:http/http.dart' as http;
Future<http.Response> postRequest () async {
var url ='https://pae.ipportalegre.pt/testes2/wsjson/api/app/ws-authenticate';
var body = jsonEncode({ 'data': { 'apikey': '12345678901234567890' } });
print("Body: " + body);
http.post(url,
headers: {"Content-Type": "application/json"},
body: body
).then((http.Response response) {
print("Response status: ${response.statusCode}");
print("Response body: ${response.contentLength}");
print(response.headers);
print(response.request);
});
}
我对请求的响应有问题,它应该有一个带有 json 的主体,但是出了问题,我认为是我在主体请求上发送的 json,因为它是一个嵌套的 json 对象,并且键的值是一个 json 对象。我很想知道如何正确解析 json 并将其插入到请求正文中。
这是标头响应:
{set-cookie: JSESSIONID=DA65FBCBA2796D173F8C8D78AD87F9AD;path=/testes2/;HttpOnly, last-modified: Thu, 10 May 2018 17:15:13 GMT, cache-control: no-store, no-cache, must-revalidate, max-age=0, post-check=0, pre-check=0, date: Thu, 10 May 2018 17:15:13 GMT, content-length: 0, pragma: no-cache, content-type: text/html, server: Apache-Coyote/1.1, expires: Tue, 03 Jul 2001 06:00:00 GMT}
这就是应该的样子:
Server: Apache-Coyote/1.1
Expires: Tue, 03 Jul 2001 06:00:00 GMT
Last-Modified: Thu, 10 May 2018 17:17:07 GMT

Keep-Alive: timeout=5, max=100
Connection: Keep-Alive

正文响应为空,我认为这是因为我根据请求发送的正文,任何人都可以帮助我处理值中的嵌套 json 对象吗?
