我想做一個Unsplash照片客戶端,它需要我使用網站的API。根據文檔,爲了訪問照片相關信息(如pageURL,imagesURL等)oAuth2.0是必需的。它聲明我必須做以下事情:我應該如何在swift中獲得OAuth2.0訪問令牌?
- 指示用戶帶有一些查詢參數到https://unsplash.com/oauth/authorize。
- 如果用戶接受該請求,則用戶將被重定向到
redirect_ui
(的參數之一),與在代碼查詢參數 - 授權碼使POST請求https://unsplash.com/oauth/token一些參數。
這是我試過的代碼來實現這一點:
ViewController.swift
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
authenticator()
// Do any additional setup after loading the view, typically from a nib.
}
func authenticator(){
Alamofire.request(.GET, "https://unsplash.com/oauth/authorize", parameters: [
"client_id": "2902affb00634248f77b3c5c7a4ba4232fa36e3cbaad826b223a27f3df57e642"
, "redirect_uri": "Sample//:" ,
"response_type" : "code" ,
"scope":"" ]).responseJSON{ response in
print("original URL request : \(response.request) ")
print("URL response : \(response.response) ")
}
Alamofire.request(.POST, "https://unsplash.com/oauth/authorize", parameters: [
"client_id" : "2902affb00634248f77b3c5c7a4ba4232fa36e3cbaad826b223a27f3df57e642",
"client_secret":"6e85c0e5bcda025f0553e1343dcbdd8a892b0db1cc3a653055d84ce44c217bb9",
"redirect_uri" : "Sample//:" ,
"code" : "c15781809f4ee781e6019b958a2702be0dab61e89df96863693dbd7d48bacd53" ,
"grant_type":"authorization_code" ])
.responseJSON { response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
}
}
但是,這是我所得到的:

如何我應解決這個錯誤?
我仍然試圖找出這一點。沒有成功。 – 209135
