从 Yelp Api 获取信息

Question

我正在连接 Yelp Api 以获取数据，然后以卡片格式显示这些数据。但是，我的问题是我似乎无法将 yelp 数据传递到该数组中以提取 yelp 数据。我该怎么做呢？如何在 20 家餐厅的规模上做到这一点？

这是我获取信息的方式：

import Foundation
import Moya

private let apiKey = "<api key>"

enum YelpService {
    enum BuisnessesProvider: TargetType {
        var baseURL: URL {
            return URL(string: "https://api.yelp.com/v3/businesses")!
        }
        
        var path: String {
            switch self {
            case .search:
                return "/search"
            }
        }
        
        var method: Moya.Method {
            return .get
        }
        
        var sampleData: Data {
            return Data()
        }
        
        var task: Task {
            switch self {
            case let .search(loc):
                return .requestParameters(parameters: ["location": loc, "term": "restaurants", "limit": 1], encoding: URLEncoding.queryString)
            }
        }
        
        var headers: [String : String]? {
            return ["Authorization": "Bearer \(apiKey)"]
        }
        
        case search(loc: String)
        
    }
}

struct Root: Codable {
    let businesses: [Business]
}

struct Business: Codable {
    let id: String
    let name: String
    let imageUrl: URL
    let rating: Double
    let url: String
}

struct RestaurantListViewModel {
    let name: String
    let imageUrl: URL
    let id: String
    let rating: Double
    let url: String
}


extension RestaurantListViewModel {
    init(business: Business) {
        self.name = business.name
        self.id = business.id
        self.imageUrl = business.imageUrl
        self.rating = business.rating
        self.url = business.url
    }
}

调用get函数：

let service = MoyaProvider<YelpService.BuisnessesProvider>()
        let jsonDecoder = JSONDecoder()
        jsonDecoder.keyDecodingStrategy = .convertFromSnakeCase
        service.request(.search(loc: "98117")) { result in
            switch result {
            case .success(let response):
                let root = try? self.jsonDecoder.decode(Root.self, from: response.data)
                let viewModels = root?.businesses.compactMap(RestaurantListViewModel.init)
                print(viewModels!)
                print(Restaurants.mock)
                Restaurants.viewModels = viewModels!
//                print(try? JSONSerialization.jsonObject(with: response.data, options: []))
            case .failure(let error):
                print("Error = \(error)")
            }
        }

最后检索它：

    let name: String
    let imageUrl: URL
    let id: String
    let rating: Double
    let url: String
    
    static var viewModels: [RestaurantListViewModel] = []
    static var mock: [Restaurants] = [
        Restaurants(name: "Silverio's Mexican Kitchen", imageUrl: URL(string: "https://mainsite-prod-cdn.azureedge.net/partner-images/432257/micrositeimage_p1.jpg")!, id: "hjkhjhjh", rating: 2, url: "https://google.com"),
        Restaurants(name: "Taqueria La Esquinita", imageUrl: URL(string: "https://s3-media0.fl.yelpcdn.com/bphoto/x-KCQ7osmvBWLA9WpPdO_Q/o.jpg")!, id: "hjdha", rating: 3, url: "https://google.com")
    ]

我想我使用 CDYelpFusionKit 得到了答案。我唯一的问题是当我通过 Cocoapods 安装时，我收到了这个错误：

Multiple commands produce '/Users/mcrich/Library/Developer/Xcode/DerivedData/Pickt-fpbpwbgjikipuabwpwmkowpgeelv/Build/Products/Debug-iphonesimulator/Pickt.app/Frameworks/CDYelpFusionKit.framework': 1) Target 'Pickt' has copy command from '/Users/mcrich/Library/Developer/Xcode/DerivedData/Pickt-fpbpwbgjikipuabwpwmkowpgeelv/Build/Products/Debug-iphonesimulator/CDYelpFusionKit.framework' to '/Users/mcrich/Library/Developer/Xcode/DerivedData/Pickt-fpbpwbgjikipuabwpwmkowpgeelv/Build/Products/Debug-iphonesimulator/Pickt.app/Frameworks/CDYelpFusionKit.framework' 2) That command depends on command in Target 'Pickt': script phase “[CP] Embed Pods Frameworks”

Answer 1

修复它，它正在获取数据并附加它，内容只是没有显示，因为它会在完成之前加载。

Answer 2

为什么您不使用“业务”模型保存在数组中。 已经具有您要在“RestaurantListViewModel”中复制的值

>             let jsonDecoder = JSONDecoder()

>                 switch result {
>                 case .success(let response):
>                     let root = try? self.jsonDecoder.decode(Root.self, from: response.data)
>                     array.append(contentsOf:root.businesses)
>     //                print(try? JSONSerialization.jsonObject(with: response.data, options: []))

>                     print("Error = \(error)")
>                 }
>             }

另外，使用 limit 和 offset 查询参数来获取页面信息并使用 array.count() 作为偏移量，并且在 yelp API 中默认限制为 20
