Question

const API_URL = 'http://www.omdbapi.com/?i=tt3896198&apikey=caca2ca6';
const App = () => {

const searchMovies = async (title) => {

const response = await fetch(`${API_URL}&s=${title}`);

const data = await response.json();

console.log(data.Search);

useEffect=(() => {
searchMovies('Batman');

return(
<h1>Apppi</h1>
);

export default App;

上面的代码应该在控制台的API中显示电影标题，我正在观看的教程已经显示了标题。有人能帮我解决这个问题吗?由于

Answer 1

useeffect有语法错误

remove = between useEffect and parentheses

useEffect(() => {
searchMovies('Batman');
}, []); 

Answer 2

请始终在try-catch中调用API，这样你的应用程序就不会崩溃，你可能会记录错误，你必须在括号前删除useEffect中的=。

const API_URL = 'http://www.omdbapi.com/?i=tt3896198&apikey=caca2ca6';

const App = () => {

const searchMovies = async (title) => {
try {
const response = await fetch(`${API_URL}&s=${title}`);

const data = await response.json();


console.log(data.Search);
} catch (error) {
console.log("error", error)
}
}

useEffect(() => {
searchMovies('Batman');
}, []); 

return(
<h1>Apppi</h1>
);
}
export default App;
