**我正在使用get方法接收数据,这已经成功完成,现在我如何在另一个类的文本小部件中显示这些响应?**这是我使用get方法的API类:
const apiHost = 'andruxnet-random-famous-quotes.p.rapidapi.com';
const apiUrl = 'https://andruxnet-random-famous-quotes.p.rapidapi.com/';
const apiKey = '14b77a3e77msh224667c7b07c6edp170846jsn2144e4d9735f';
class Quote {
static Future getQuote() async {
var client = http.Client();
var uri = Uri.parse(apiUrl);
var response = await client.get(
uri,
headers: {'X-RapidAPI-Key': apiKey, 'X-RapidAPI-Host': apiHost},
);
if(response.statusCode == 200){
var json = response.body;
return getQuoteFromJson(json);
}
else {
throw Exception(response.reasonPhrase);
}
}
}
此为型号:
import 'dart:convert';
List<GetQuote> getQuoteFromJson(String str) => List<GetQuote>.from(json.decode(str).map((x) => GetQuote.fromJson(x)));
String getQuoteToJson(List<GetQuote> data) => json.encode(List<dynamic>.from(data.map((x) => x.toJson())));
class GetQuote {
GetQuote({
required this.quoteText,
required this.author,
});
String quoteText;
String author;
factory GetQuote.fromJson(Map<String, dynamic> e) => GetQuote(
quoteText: e["quote"],
author: e["author"],
);
Map<String, dynamic> toJson() => {
"quote": quoteText,
"author": author,
};
}
界面代码如下:
class QuotePage extends StatefulWidget {
const QuotePage({super.key});
@override
State<QuotePage> createState() => _QuotePageState();
}
class _QuotePageState extends State<QuotePage> {
List<GetQuote> quote = [];
@override
void initState() {
super.initState();
getData();
}
getData() async{
final response = await Quote.getQuote();
setState(() {
quote = response;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(

我正在使用get方法接收数据,这已经成功完成了,现在我如何在另一个类的文本小部件中显示这些响应?

要在文本小部件中显示API响应,您应该使用API响应中的实际数据替换硬编码文本。以下是如何修改_QuotePageState类和包含文本小部件的Column:
首先,用一个空的GetQuote对象而不是一个空的列表初始化你的quote变量。这将允许你在文本小部件中显示一个引用及其作者。
接下来,修改getData方法以处理响应不是列表的情况:
最后,更新Column中的Text小部件,以显示quote对象的quoteText和author属性:
现在,API响应将显示在文本小部件中。
