使用 React 建立電影尋找網站-css教學-PHP中文網

Building a Movie Finder Website using React

介紹

在本部落格中，我們將逐步介紹使用 React 和 OMDB API 建立 Movie Finder 網站的過程。該網站允許用戶按復仇者聯盟、星際大戰和系列等類別瀏覽電影，並使用特定查詢搜尋電影。每部電影都有其詳細頁面，讓您輕鬆探索更多有關您喜愛的電影。

項目概況

電影查找網站使用者能夠：

瀏覽復仇者聯盟和星際大戰等類別。
透過關鍵字搜尋電影。
查看詳細的電影資訊（海報、類型、導演、演員等）。
透過簡潔、現代的設計輕鬆瀏覽網站。

特徵

使用 OMDB API 動態取得資料。
響應式設計，提供更好的使用者體驗。
提供即時結果的搜尋功能。
在取得資料時載入指標。
在單獨的頁面上查看各個電影的詳細資訊。

使用的技術

React：用於建立 UI 元件的前端函式庫。
React Router：用於導航和路由。
Axios：用於向 OMDB API 發出 HTTP 請求。
OMDB API：取得電影詳細資訊。
CSS：用於設計應用程式的樣式。

用法

1. 首頁

首頁展示了兩類電影：《復仇者聯盟》和《星際大戰》。當用戶點擊電影卡時，他們會被重新導向到詳細的電影頁面。

來自 Home.js 的程式碼片段：

import React, { useEffect, useState } from "react";
import axios from "axios";
import { useNavigate } from "react-router-dom";
import Movies from "./Movies";
import Series from "./Series";

const Home = () => {
  const [avengersMovies, setAvengersMovies] = useState([]);
  const [starWarsMovies, setStarWarsMovies] = useState([]);
  const [loadingAvengers, setLoadingAvengers] = useState(true);
  const [loadingStarWars, setLoadingStarWars] = useState(true);
  const navigate = useNavigate();

  useEffect(() => {
    fetchMovies("Avengers", setAvengersMovies, setLoadingAvengers);
    fetchMovies("Star Wars", setStarWarsMovies, setLoadingStarWars);
  }, []);

  const fetchMovies = (query, setMovies, setLoading) => {
    axios
      .get(`http://www.omdbapi.com/?s=${query}&apikey=you_api_key`)
      .then((response) => {
        if (response.data.Search) {
          setMovies(response.data.Search);
        } else {
          setMovies([]); // Clear movies if no results
        }
      })
      .catch((error) => {
        console.error(`There was an error fetching the ${query} movies!`, error);
        setMovies([]); // Clear movies if there is an error
      })
      .finally(() => {
        setLoading(false);
      });
  };

  const handleCardClick = (id) => {
    navigate(`/movie/${id}`);
  };

  const renderMovies = (movies, loading) => (
    loading ? (
      <div className="loader"><div className="load"></div></div>
    ) : (
      <div className="cards">
        {movies.length > 0 ? (
          movies.map((movie) => (
            <div key={movie.imdbID} className="card" onClick={() => handleCardClick(movie.imdbID)}>
              <img src={movie.Poster} alt={movie.Title} />
              <h2>{movie.Title}</h2>
            </div>
          ))
        ) : (
          <p>No movies found.</p>
        )}
      </div>
    )
  );

  return (
    <>
      <div className="home">
        <div className="movie-category">
          <h4>Avengers Movies</h4>
          {renderMovies(avengersMovies, loadingAvengers)}
        </div>
        <br />
        <br />
        <div className="movie-category">
          <h4>Star Wars Movies</h4>
          {renderMovies(starWarsMovies, loadingStarWars)}
        </div>
      </div>
      <Movies />
      <Series />
    </>
  );
};

export default Home;

2. 搜尋功能

使用者可以使用網站頂部的搜尋欄來搜尋任何電影。搜尋結果是根據使用者的查詢從 OMDB API 取得的。

來自 SearchResults.js 的程式碼片段：

import React, { useEffect, useState } from "react";
import axios from "axios";
import { useParams, useNavigate } from "react-router-dom";

const SearchResults = () => {
  const [movies, setMovies] = useState([]);
  const [loading, setLoading] = useState(false);
  const { query } = useParams();
  const navigate = useNavigate(); // Add this line to use navigate

  useEffect(() => {
    if (query) {
      setLoading(true);  // Set loading to true before starting the fetch
      axios
        .get(`http://www.omdbapi.com/?s=${query}&apikey=your_api_key`)
        .then((response) => {
          if (response.data.Search) {
            setMovies(response.data.Search);
          } else {
            setMovies([]); // Clear movies if no results
          }
        })
        .catch((error) => {
          console.error("There was an error fetching the movie data!", error);
        })
        .finally(() => {
          setLoading(false);  // Set loading to false once fetch is complete
        });
    }
  }, [query]);

  const handleCardClick = (id) => {
    navigate(`/movie/${id}`); // Navigate to movie detail page
  };

  return (
    <div className="search-results">
      <h4>Search Results for "{query}"</h4>
      {loading ? (
        <div className="loader"><div className="load"></div></div>  // Loader
      ) : (
        <div className="cards">
          {movies.length > 0 ? (
            movies.map((movie) => (
              <div key={movie.imdbID} className="card" onClick={() => handleCardClick(movie.imdbID)}>
                <img src={movie.Poster} alt={movie.Title} />
                <h2>{movie.Title}</h2>
              </div>
            ))
          ) : (
            <p>No results found.</p>
          )}
        </div>
      )}
    </div>
  );
};

export default SearchResults;

3. 電影詳情頁

當使用者點擊電影時，他們會被重新導向到電影詳細資料頁面。此頁面顯示電影的標題、海報、情節、演員等。

來自 MovieDetail.js 的程式碼片段：

import React, { useEffect, useState } from 'react';
import axios from 'axios';
import { useParams } from 'react-router-dom';

const MovieDetail = () => {
  const [movie, setMovie] = useState(null);
  const [loading, setLoading] = useState(true);
  const { id } = useParams();

  useEffect(() => {
    axios.get(`http://www.omdbapi.com/?i=${id}&apikey=your_api_key`)
      .then((response) => {
        setMovie(response.data);
      })
      .catch((error) => {
        console.error("There was an error fetching the movie details!", error);
      })
      .finally(() => {
        setLoading(false);
      });
  }, [id]);

  if (loading) return <div className="loader">
    <div className="load"></div>
  </div>;
  if (!movie) return <div className='loader'>No movie data found!</div>;

  return (
    <div className="movie-detail">

<div className="detail-box">
<h1>{movie.Title}</h1>
<p><strong>Year:</strong> {movie.Year}</p>
      <p><strong>Rating:</strong> {movie.imdbRating}</p>
      <p><strong>Genre:</strong> {movie.Genre}</p>
      <p><strong>Director:</strong> {movie.Director}</p>
      <p><strong>Actors:</strong> {movie.Actors}</p>
      <p><strong>Plot:</strong> {movie.Plot}</p>
      <p><strong>Runtime:</strong> {movie.Runtime}</p>
      <p><strong>Language:</strong> {movie.Language}</p>
      <p><strong>Country:</strong> {movie.Country}</p>
      <p><strong>Awards:</strong> {movie.Awards}</p>
</div>
    <div className="img-box">
    <img src={movie.Poster} alt={movie.Title} />
    </div>
    </div>
  );
};

export default MovieDetail;

4. 電影和連續劇頁面

Movies.js 和 Series.js 頁面分別列出電影和電視劇。

來自 Movies.js 的程式碼片段：

import React, { useEffect, useState } from "react";
import axios from "axios";
import { useNavigate } from "react-router-dom";

const Movies = () => {
  const [movies, setMovies] = useState([]);
  const navigate = useNavigate();

      .get(`http://www.omdbapi.com/?s=Avengers&type=movie&apikey=${process.env.REACT_APP_OMDB_API_KEY}`)
      .then(response => setMovies(response.data.Search || []))
      .catch(error => console.error(error));
  }, []);

  const handleCardClick = (id) => {
    navigate(`/detail/${id}`);
  };

  return (
    <div className="movies">
      <h2>Movies</h2>
      <div className="cards">
        {movies.map(movie => (
          <div key={movie.imdbID} className="card" onClick={() => handleCardClick(movie.imdbID)}>
            <img src={movie.Poster} alt={movie.Title} />
            <h3>{movie.Title}</h3>
          </div>
        ))}

5. 導覽列組件

導覽列元件允許使用者在不同頁面之間導航並執行搜尋。

更新了 Navbar.js

import React, { useState } from "react";
import { NavLink, Link } from "react-router-dom";

const Navbar = () => {
  const [searchQuery, setSearchQuery] = useState("");

  const handleSearch = (event) => {
    if (event.key === 'Enter' && searchQuery.trim()) {
      document.getElementById('search-link').click();
    }
  };

  return (
    <div className="navbar">
      <div className="logo">
        <h1>Movie Finder</h1>
      </div>

      <div className="page-list">
        <NavLink to="/">

          type="text"
          placeholder="Search for movies or series"
          value={searchQuery}
          onChange={(e) => setSearchQuery(e.target.value)}
          onKeyDown={handleSearch}
        />
        <Link to={`/search/${searchQuery}`} id="search-link">
          <button>Search</button>
        </Link>
