在Swift中使用标头发出HTTP请求

Question

我正在尝试向Imgur API发出HTTP请求.我正在尝试检索与标签"cats"相关的所有图像.根据Imgur API,网址为:https://api.imgur.com/3/gallery/t/cats

Imgur API声明了以下有关获取请求所需的授权:

对于公共只读和匿名资源,例如获取图像信息,查找用户评论等,您只需要client_id在您的请求中发送授权标题.如果您想要匿名上传图像(图像
不附加到帐户),或者您想要创建匿名
相册,这也适用.这让我们知道哪个应用程序正在访问API.

Authorization: Client-ID YOUR_CLIENT_ID

我看了下面的问题,并尝试了那里的建议,但没有一个有帮助.

带有凭据的JSON NSURLRequest

带参数的Swift GET请求

如何在Swift中创建一个Http get并设置httpHeader？

我目前的代码是这样的:

let string = "https://api.imgur.com/3/gallery/t/cats"
let url = NSURL(string: string)
let request = NSMutableURLRequest(URL: url!)
request.setValue("clientIDhere", forHTTPHeaderField: "Authorization")
//request.addValue("clientIDhere", forHTTPHeaderField: "Authorization")
request.HTTPMethod = "GET"
let session = NSURLSession.sharedSession()

let tache = session.dataTaskWithRequest(request) { (data, response, error) -> Void in
    if let antwort = response as? NSHTTPURLResponse {
        let code = antwort.statusCode
        print(code)
    }
}
tache.resume()

但我不断获得403的状态代码,这意味着需要授权.我究竟做错了什么？

Answer 1

我认为您需要将Client-ID字符串添加到您的实际客户端ID以及标头值:

request.setValue("Client-ID <your_client_id>", forHTTPHeaderField: "Authorization")

Answer 2

更新为 swift 4 ：

func fetchPhotoRequest(YOUR_CLIENT_ID: String)  {
    let string = "https://photoslibrary.googleapis.com/v1/albums"
    let url = NSURL(string: string)
    let request = NSMutableURLRequest(url: url! as URL)
    request.setValue(YOUR_CLIENT_ID, forHTTPHeaderField: "Authorization") //**
    request.httpMethod = "GET"
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    let session = URLSession.shared

    let mData = session.dataTask(with: request as URLRequest) { (data, response, error) -> Void in
        if let res = response as? HTTPURLResponse {
            print("res: \(String(describing: res))")
            print("Response: \(String(describing: response))")
        }else{
            print("Error: \(String(describing: error))")
        }
    }
    mData.resume()
}
