因此，我正在制作一个 iOS 应用程序，用于在 imdb 数据库上搜索电影(使用 omdb api)，并且用户可以保存收藏夹。
通过imdbTitle搜索，请求url为“https://www.omdbapi.com/?s=(imdbTitle)&type=movie”，例如，如果imdbTitle =“arq”，则响应为:
{
Response = True;
Search = (
{
Poster = "https://images-na.ssl-images-amazon.com/images/M/MV5BMjAxODQ2MzkyMV5BMl5BanBnXkFtZTgwNjU3MTE5OTE@._V1_SX300.jpg";
Title = ARQ;
Type = movie;
Year = 2016;
imdbID = tt5640450;
},
{
Poster = "N/A";
Title = Arq;
Type = movie;
Year = 2011;
imdbID = tt2141601;
},
{
Poster = "N/A";
Title = "A.R.Q.";
Type = movie;
Year = 2015;
imdbID = tt3829612;
}
);
totalResults = 3;
}
但是为了保存电影，我必须通过imdbID搜索，url:“https://www.omdbapi.com/?i=(imdbID )”，如果imdbID是搜索到的电影中的imdbID，imdbID = tt3829612，则响应为:
{
Actors = "Robbie Amell, Rachael Taylor, Shaun Benson, Gray Powell";
Awards = "N/A";
BoxOffice = "N/A";
Country = "USA, Canada";
DVD = "16 Sep 2016";
Director = "Tony Elliott";
Genre = "Sci-Fi, Thriller";
Language = English;
Metascore = "N/A";
Plot = "Trapped in a lab and stuck in a time loop, a disoriented couple fends off masked raiders while harboring a new energy source that could save humanity.";
Poster = "https://images-na.ssl-images-amazon.com/images/M/MV5BMjAxODQ2MzkyMV5BMl5BanBnXkFtZTgwNjU3MTE5OTE@._V1_SX300.jpg";
Production = Netflix;
Rated = "N/A";
Ratings = (
{
Source = "Internet Movie Database";
Value = "6.4/10";
},
{
Source = "Rotten Tomatoes";
Value = "60%";
}
);
Released = "16 Sep 2016";
Response = True;
Runtime = "88 min";
Title = ARQ;
Type = movie;
Website = "N/A";
Writer = "Tony Elliott";
Year = 2016;
imdbID = tt5640450;
imdbRating = "6.4";
imdbVotes = "17,481";
}
所以，我的 Movie 类必须具有以下属性:海报、标题、运行时、流派、导演、 Actor 、情节、已发布、imdbID 和 imdbRating(要在我的 UI View 上显示此属性，当然，imdbID 除外)
我是一个初学者，我对所有这些事情感到非常困惑(以前从未使用过 API 数据)。
无论如何，经过大量搜索后，我发现有一种方法可以使用 AlamofireObjectMapper 将此响应作为数组获取。
我已经有了我的请求功能:
func searchMoviesOnJson(imdbTitle: String, completionHandler: @escaping (Dictionary<String, Any>?) -> ()) {
let urlByName: String = "https://www.omdbapi.com/?s=\(imdbTitle)&type=movie"
//returns a list of movies that contains the title searched
//------------------------------------------------
Alamofire.request(urlByName).responseJSON {
response in
switch response.result {
case .success(let value):
let moviesJSON = value
completionHandler(moviesJSON as? Dictionary<String, Any>)
case .failure(_):
completionHandler(nil)
}
}
//------------------------------------------------
}
func getMovieFromJson(imdbID: String, completionHandler: @escaping (Dictionary<String, String>) -> ()) {
let urlById: String = "https://www.omdbapi.com/?i=\(imdbID)"
//returns a single movie information
//------------------------------------------------
Alamofire.request(urlById).responseJSON {
response in
if let moviesJSON = response.result.value {
completionHandler(moviesJSON as! Dictionary<String, String>)
}
}
//------------------------------------------------
}
那么，有人可以向我解释一下(就像向 child 解释一样)我该如何进行此映射吗？我创建了一个 Movie.swift，在这个文件中我将放置我的 Movie 类和 MovieDAO 类。
如何使用 AlamofireObjectMapper 实现这两个类以及我必须在请求方法中更改谁？
更新:
class Movie {
let poster: String?
let title: String?
let runtime: String?
let genre: String?
let director: String?
let actors: String?
let plot: String?
let released: String?
let imdbID: String?
let imdbRating: String?
init(poster: String?, title: String?, runtime: String?, genre: String?, director: String?, actors: String?, plot: String?, released: String?, imdbID: String?, imdbRating: String?) {
//checking if is nil
if let isPoster = poster {
self.poster = isPoster
} else {
self.poster = nil
}
if let isTitle = title {
self.title = isTitle
} else {
self.title = nil
}
if let isGenre = genre {
self.genre = isGenre
} else {
self.genre = nil
}
if let isRuntime = runtime {
self.runtime = isRuntime
} else {
self.runtime = nil
}
if let isDirector = director {
self.director = isDirector
} else {
self.director = nil
}
if let isActors = actors {
self.actors = isActors
} else {
self.actors = nil
}
if let isPlot = plot {
self.plot = isPlot
} else {
self.plot = nil
}
if let isReleased = released {
self.released = isReleased
} else {
self.released = nil
}
if let isImdbID = imdbID {
self.imdbID = isImdbID
} else {
self.imdbID = nil
}
if let isImdbRating = imdbRating {
self.imdbRating = isImdbRating
} else {
self.imdbRating = nil
}
}
}
更新2
我按照你所说的那样声明了变量 movieDetail，但是 xcode 显示错误并建议我可以添加参数，所以我这样做了，但问题没有解决。
最佳答案
您必须解析收到的 JSON: 例如如果收到的 json 是:
{
Response = True;
Search = (
{
Poster = "https://images-na.ssl-images-amazon.com/images/M/MV5BMjAxODQ2MzkyMV5BMl5BanBnXkFtZTgwNjU3MTE5OTE@._V1_SX300.jpg";
Title = ARQ;
Type = movie;
Year = 2016;
imdbID = tt5640450;
},
{
Poster = "N/A";
Title = Arq;
Type = movie;
Year = 2011;
imdbID = tt2141601;
},
{
Poster = "N/A";
Title = "A.R.Q.";
Type = movie;
Year = 2015;
imdbID = tt3829612;
}
);
totalResults = 3;
}
正如您所提到的，如果您已将 json 响应存储在 NSDictionary 中
您可以通过以下方式访问搜索结果的值
var moviesArray = [Movie]() //array of your Movie class
var imdbIdArray = [String]()
if let searchResults = moviesJSON["Search"] as? NSArray {
for searchResult in searchResults {
let movieResult = searchResult as! Dictionary<String,String>
let movieDetail = Movie()
movieDetail.title = movieResult["Title"]
movieDetail.type = movieResult["Type"]
//similarly you can do it for other params as well
moviesArray.append(movieDetail)
let imdbId = movieResult["imdbId"]
imdbIdArray.append(imdbId)
}
}
class Movie: NSObject {
var title = String()
var type = String()
}
现在 movieArray 由结果集中返回的电影列表组成。
