我的代码如下:
HttpClient client = new HttpClient();
client.get('192.168.4.1', 80, '/').then((HttpClientRequest req) {
print(req.connectionInfo);
return req.close();
}).then((HttpClientResponse rsp) {
print(rsp);
});
我正在尝试在没有Internet连接的本地wifi网络中发出HTTP-Get请求,但是我总是收到以下错误消息:
E / flutter(8386):[错误:flutter / shell / common / shell.cc(184)] Dart错误:未处理的异常: E / flutter(8386):SocketException:连接失败(OS错误:网络无法访问,errno = 101),地址= 192.168.4.1,端口= 80 E / flutter(8386):#0 _rootHandleUncaughtError。 (dart:async / zone.dart:1112:29) E / flutter(8386):#1 _microtaskLoop(dart:async / schedule_microtask.dart:41:21) E / flutter(8386):#2 _startMicrotaskLoop(dart:async / schedule_microtask.dart:50:5)
我正在使用Android设备。

我可以像这样从Flutter发出http GET请求:
String androidEmulatorLocalhost = 'http://10.0.2.2:3000';
Response response = await get(androidEmulatorLocalhost);
String bodyText = response.body;
这需要import 'package:http/http.dart';
。
这是我的Node.js server在本地运行:
const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello World\n');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
