使用 React 构建电影查找网站

php中文网

介绍

在本博客中,我们将逐步介绍使用 react 和 omdb api 构建 movie finder 网站的过程。该网站允许用户按复仇者联盟、星球大战和系列等类别浏览电影,并使用特定查询搜索电影。每部电影都有其详细页面,让您轻松探索更多有关您喜爱的电影。

项目概况

电影查找网站使用户能够:

  • 浏览复仇者联盟和星球大战等类别。
  • 通过关键字搜索电影。
  • 查看详细的电影信息(海报、类型、导演、演员等)。
  • 通过简洁、现代的设计轻松浏览网站。

特征

  • 使用 omdb api 动态获取数据。
  • 响应式设计,提供更好的用户体验。
  • 提供即时结果的搜索功能。
  • 在获取数据时加载指标。
  • 在单独的页面上查看各个电影的详细信息。

使用的技术

  • react:用于构建 ui 组件的前端库。
  • react router:用于导航和路由。
  • axios:用于向 omdb api 发出 http 请求。
  • omdb api:获取电影详细信息。
  • css:用于设计应用程序的样式。

项目结构

这是该项目的目录结构:

movie-finder/
├── public/
├── src/
│   ├── components/
│   │   └── navbar.js
│   │   └── footer.js
│   ├── pages/
│   │   └── home.js
│   │   └── movies.js

│   │   └── searchresults.js
│   │   └── moviedetail.js
│   └── app.js
│   └── app.css
└── package.json

安装

  1. 克隆存储库:

    git clone https://github.com/abhishekgurjar-in/movie-finder.git
    cd movie-finder
    
  2. 安装依赖项:

    npm install
    
  3. 从 omdb api 获取您的 api 密钥。

  4. 在项目根目录中创建一个 .env 文件并添加您的 api 密钥:

    react_app_omdb_api_key=yourapikey
    
  5. 运行项目:

    npm start
    

用法

1. 主页

主页展示了两类电影:《复仇者联盟》和《星球大战》。当用户点击电影卡时,他们会被重定向到详细的电影页面。

来自 home.js 的代码片段:

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)}>
              @@##@@
              <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. 搜索功能

用户可以使用网站顶部的搜索栏搜索任何电影。搜索结果是根据用户的查询从 omdb api 获取的。

来自 searchresults.js 的代码片段:

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)}>
                @@##@@
                <h2>{movie.title}</h2>
              </div>
            ))
          ) : (
            <p>no results found.</p>
          )}
        </div>
      )}
    </div>
  );
};

export default searchresults;

3. 电影详情页

当用户点击电影时,他们会被重定向到电影详细信息页面。此页面显示电影的标题、海报、情节、演员等。

来自 moviedetail.js 的代码片段:

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">
    @@##@@
    </div>
    </div>
  );
};

export default moviedetail;

4. 电影和连续剧页面

movies.jsseries.js 页面分别列出电影和电视剧。

来自 movies.js 的代码片段:

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();

  useeffect(() => {
    axios
      .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)}>
            @@##@@
            <h3>{movie.title}</h3>
          </div>
        ))}
      </div>
    </div>
  );
};

export default movies;

series.js 中的代码片段:

import react, { useeffect, usestate } from "react";
import axios from "axios";
import { usenavigate } from "react-router-dom";

const series = () => {
  const [series, setseries] = usestate([]);
  const navigate = usenavigate();

  useeffect(() => {
    axios
      .get(`http://www.omdbapi.com/?s=star wars&type=series&apikey=${process.env.react_app_omdb_api_key}`)
      .then(response => setseries(response.data.search || []))
      .catch(error => console.error(error));
  }, []);

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

  return (
    <div classname="series">
      <h2>tv series</h2>
      <div classname="cards">
        {series.map(show => (
          <div key={show.imdbid} classname="card" onclick={() => handlecardclick(show.imdbid)}>
            @@##@@
            <h3>{show.title}</h3>
          </div>
        ))}
      </div>
    </div>
  );
};

export default series;

5. 导航栏组件

导航栏组件允许用户在不同页面之间导航并执行搜索。

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="/">
          <h4>home</h4>
        </navlink>
        <navlink to="/movies">
          <h4>movies</h4>
        </navlink>
        <navlink to="/series">
          <h4>tv series</h4>
        </navlink>
      </div>
      <div classname="search-box">
        <input
          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>
      </div>
    </div>
  );
};

export default navbar;

6.页脚组件

页脚组件提供简单的页脚消息。

页脚.js

import react from 'react';

const footer = () => {
  return (
    <div classname='footer'>
      made with <span>❤️</span> by abhishek gurjar
    </div>
  );
};
