【问题描述】：
我是 Flutter 开发的新手。能否请任何人告诉我单击按钮时如何将参数传递给 url。谢谢你。
import 'package:flutter/material.dart';
import 'package:minerva_admin/Homescreen.dart';
import 'dart:async';
import 'dart:convert';
import 'package:http/http.dart' as http;
class Login extends StatefulWidget {
@override
State<StatefulWidget> createState() {
return new LoginState();
}
}
class LoginState extends State<Login> {
final TextEditingController _userController = new TextEditingController();
final String url = "http://192.155.1.40:8088/restaurants";
List data;
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text("Minerva Money"),
centerTitle: true,
backgroundColor: Colors.green,
),
backgroundColor: Colors.white,
body: new Container(
alignment: Alignment.topCenter,
child: new ListView(
children: <Widget>[
//image/profi
//form
new Container(
margin: const EdgeInsets.only(top: 100.0),
child: new Column(
children: <Widget>[
new TextField(
controller: _userController,
decoration: new InputDecoration(
hintText: 'Enter Email/Mobile Number',
icon: new Icon(Icons.person)
),
),
new Padding(padding: new EdgeInsets.all(10.5)), //add padding
new Center(
// Login button
child: new RaisedButton(
onPressed: (){
getSWData(_userController.toString());
},
color: Colors.green,
child: new Text("Login",
style: new TextStyle(color: Colors.white,
fontSize: 16.9))),
// Clear button
)
],
),
), //form ends here
new Padding(
padding: const EdgeInsets.all(14.0)),
],
),
),
);
}
Future<String> getSWData(String email) async {
var res = await http.get(
Uri.encodeFull(url), headers: {"Accept": "application/json"});
print("response" + "$url");
setState(() {
var resBody = json.decode(res.body);
// data = resBody["restos_cities"];
print("response" + "$resBody");
});
return "succees";
}
}
任何人都可以解释我如何在单击按钮获取数据时将“电子邮件”参数中的文本字段数据发送到 Web 服务。先感谢您。我在 pubspec 文件中添加了 http: ^0.11.3+16。
