因此，我正在使一个iOS应用程序在imdb数据库中搜索电影（使用omdb api），并且用户可以保存收藏夹。
要通过imdbTitle进行搜索，例如，如果imdbTitle =“ arq”，则请求URL为“ https://www.omdbapi.com/?s=(imdbTitle)&type=movie”，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;
}
但是要保存电影，我必须通过imdbID搜索，URL：“ https://www.omdbapi.com/?i=(imdbID）”，如果imdbID是来自所搜索电影的电影，则imdbID = tt3829612，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";
}
因此，我的Movie类必须具有以下属性：海报，标题，运行时，流派，导演，演员，情节，发行，imdbID和imdbRating（要在我的UI视图上显示，当然除了imdbID除外）
我是一个初学者，我对所有这些东西都感到困惑（以前从未使用过API数据）。
无论如何，经过大量搜索之后，我发现有一种方法可以使用AlamofireObjectMapper作为数组获得此响应。
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>)
}
}
//------------------------------------------------
}
因此，有人可以向我解释（例如您会向孩子解释）我该如何进行映射？我创建了一个Movie.swift，然后在该文件中放置Movie类和MovieDAO类。
如何使用AlamofireObjectMapper来实现这两个类，我的请求方法中必须更改谁？
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
我按照您所说的那样声明了movieDetail变量，但是xcode显示了一个错误并建议我可以添加参数，所以我做到了，但没有解决。
最佳答案
您将必须解析收到的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;
}
如前所述，如果您已将json响应存储在NSDictionary中
您可以按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，moviesArray由结果集中返回的电影列表组成。
