虽然我的代码输出正确,但我更关心结构以及它是否符合 API“应用程序”的标准。我在下面提供我的代码,它在我的 App.js 文件中,对它有什么建议,因为我想稍后将它放入我的投资组合中?
import { useState } from "react";
function App() {
const api = {
key: "c6440629646261c9d5423619112f0341",
base: "http://api.openweathermap.org/data/2.5",
};
const [search, setSearch] = useState("");
const [weather, setWeather] = useState({});
const [error, setError] = useState(null);
const searchPressed = () => {
fetch(`${api.base}/weather?q=${search}&units=metric&APPID=${api.key}`)
.then((res) => {
if (!res.ok) {
throw new Error("Network response was not ok");
}
return res.json();
})
.then((result) => {
setWeather(result);
setError(null);
})
.catch((error) => {
console.log(error);
setError("Something went wrong. Please try again.");
});
};
return (
<div className="container mx-auto mt-8">
<h1 className="mb-4 text-3xl font-bold">Weather App</h1>
{/* Search Box */}
<div className="flex mb-4">
<input
type="text"
placeholder="Enter a city"
value={search}
onChange={(e) => setSearch(e.target.value)}
className="w-full p-2 mr-2 border-2 border-gray-200 rounded-lg focus:outline-none focus:border-blue-500"
/>
<button
onClick={searchPressed}
className="px-4 py-2 font-bold text-white bg-blue-500 rounded-lg hover:bg-blue-700"
>
Search
</button>
</div>
{/* Ternary operation */}
{typeof weather.main != "undefined" ? (
<div className="text-center">
<p className="text-lg">
{weather.name}, {weather.sys.country}
</p>
<p className="text-6xl font-bold">{weather.main.temp} C°</p>
<p className="text-lg">Feels like: {weather.main.feels_like} C°</p>
<p className="text-lg">{weather.weather[0].main}</p>
</div>
) : error ? (
<p className="text-center text-red-500">{error}</p>
) : null}
</div>
);
}
export default App;
我想做的一件事是通过按键盘上的“返回”键使搜索按钮起作用。我该如何开始?
