無法執行URL請求SWIFT

我正在嘗試進行 API 呼叫，但它向我拋出狀態代碼 401（這是未經授權的客戶端回應），我無法訪問那里的 JSON 資料。我已經通過表示 PostMan 資料的方式嘗試了我的 API 密鑰。也許我錯過了一些東西。

標記： - 錯誤示例 狀態代碼應為 2xx 但為 401 - 狀態代碼表示基于波紋管。

guard response.statusCode >= 200 && response.statusCode < 300 else {
            print("Status code should be 2xx but is \(response.statusCode)")
            return
        }

馬克： - 我的代碼

   func fetchDat() {

    guard let url = URL(string: "https://odds.p.rapidapi.com/v1/sports") else { return }

    var request = URLRequest(url: url, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0)
    request.httpMethod = "GET"
    request.setValue("c15b711e56msh05b5f41ea7d8e5dp1b1b56jsne1f975246c84", forHTTPHeaderField: "x-rapidapi-key")
    
    downloadData(fromURL: url) { returnedData in
        if let data = returnedData {
            //MARK: - JSON Decoder
            guard let newPosts = try? JSONDecoder().decode([Result].self, from: data) else { return }
                DispatchQueue.main.async { [weak self] in
                    self?.res = newPosts
                }
        } else {
            print("No data returned")
        }
    }
    
}

func downloadData(fromURL url: URL, completionHandler: @escaping(_ data: Data?) -> Void) {
    
    //MARK: - URL Session Error, data, Response Handler
    URLSession.shared.dataTask(with: url) { (data, response, error) in
        
        //MARK: - More Recommended Method
        guard
            let data = data,
            error == nil,
            let response = response as? HTTPURLResponse,
                response.statusCode >= 200 && response.statusCode < 300 else {
            print("Error Downloading Data")
            completionHandler(nil)
            return
            }
    completionHandler(data)
        }.resume()
    
    }

}

Bellow MARK： - 快速 API NSURLSESSION 訪問模板

import Foundation

let headers = [
    "x-rapidapi-host": "odds.p.rapidapi.com",
    "x-rapidapi-key": "c15b711e56msh05b5f41ea7d8e5dp1b1b56jsne1f975246c84"
]

let request = NSMutableURLRequest(url: NSURL(string: "https://odds.p.rapidapi.com/v1/sports")! as URL,
                                        cachePolicy: .useProtocolCachePolicy,
                                    timeoutInterval: 10.0)
request.httpMethod = "GET"
request.allHTTPHeaderFields = headers

let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
    if (error != nil) {
        print(error)
    } else {
        let httpResponse = response as? HTTPURLResponse
        print(httpResponse)
    }
})

dataTask.resume()

您可以參考下面的螢屏截圖，我的 POSTMAN 標頭正在作業并且鏈接本身正在作業。

我已經更新了我的代碼，現在看起來像這樣：

func fetchDat() {
        
        
//        guard let url = URL(string: "https://jsonplaceholder.typicode.com/posts") else { return }
        guard let url = URL(string: "https://odds.p.rapidapi.com/v1/sports") else { return }
        var request = URLRequest(url: url, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0)
        request.httpMethod = "GET"
        request.setValue("c15b711e56msh05b5f41ea7d8e5dp1b1b56jsne1f975246c84", forHTTPHeaderField: "x-rapidapi-key")
        request.setValue("odds.p.rapidapi.com", forHTTPHeaderField: "x-rapidapi-host")
        
            URLSession.shared.dataTask(with: request) { (data, response, error) in

     
                guard let data = data else {
                    print("No Data.")
                    return
                }
                
                guard error == nil else  {
                    print("Error: \(String(describing: error))")
                    return
                }
                guard let response = response as? HTTPURLResponse else {
                    print("Invalid Response")
                    return
                }
                guard response.statusCode >= 200 && response.statusCode < 300 else {

                print("Status code should be 2xx but is \(response.statusCode)")
                            
                        return
                    }
                    
                    guard let newPosts = try? JSONDecoder().decode([Result].self, from: data) else { return }
                    DispatchQueue.main.async { [weak self] in
                        self?.res = newPosts
                    }
    }.resume()
}
        
    }

uj5u.com熱心網友回復：

您正在設定request.setValue("API KEY", forHTTPHeaderField: "Authorization"). 但是，在示例代碼中，API 需要名稱為 的 API 密鑰x-rapidapi-key。因此request.setValue("API KEY", forHTTPHeaderField: "x-rapidapi-key")應該作業。當然不要忘記將您自己的 Key 正確插入占位符。
