Question

我想在android中使用tmdb api显示电影的类型，但事情是在tmdb api中首先我们必须找出类型id然后我们可以显示类型名称＆amp;我能够显示流派id但不能显示流派名称。请帮帮我

那么，当我遇到困难时如何解决这个问题＆amp;无法找到任何方法。那么，当我使用这个API时，如何使用tmdb api获取类型名称。请帮忙

Answer 1

您必须将您的流派_id 与您可以从此处获取的流派列表进行映射：https://developers.themoviedb.org/3/genres/get-movie-list。我希望我能帮助你:) （data["results"][0]["genre_ids"] 是我在这个例子中的流派列表）这是我的代码：

    const genresRes = await fetch("https://api.themoviedb.org/3/genre/" + data["results"][0]["media_type"] + "/list?api_key=de51817441f3aca4f2ec89ee99f6c68c&language=en-US");
    const genresData = await genresRes.json();
    let genresThing = genresData["genres"]
    let genresHash = {};
    for (let i in genresThing){
        genresHash[genresThing[i]["id"]] = genresThing[i]["name"]
    }
    let genres = ""
    for (let i in data["results"][0]["genre_ids"]){
        genres += genresHash[data["results"][0]["genre_ids"][i]] + ", ";
    }
    this.dataNow.genres = genres
    console.log(this.dataNow.genres)

Answer 2

您可以使用此 API 获取电影的更多信息，使用电影 ID。 https://developers.themoviedb.org/3/movies/get-movie-details 在这里您可以获得流派 ID 和流派名称的列表。我希望我有帮助:)
