Question

我正在尝试使用本机URL和URLRequest类从iOS客户端检索OAuth令牌以使用Yelp的Fusion API，但它在＆＃34; tokenInfo＆＃34;中给出了这个错误。变量：

client_id or client_secret parameters not found. Make sure to provide 
client_id and client_secret in the body with the 
application/x-www-form-urlencoded content-type

这是我的代码：

func getToken(){
    var yelpTokenEndpoint = "https://api.yelp.com/oauth2/token"
    var tokenURL = URL(string: yelpTokenEndpoint)

    let requestJSON: [String:String] = ["client_id":"Not showing actual client id", "client_secret":"Not Gonna Show My Actual Client Secret either","grant_type":"client_credentials"]
    let requestData = try? JSONSerialization.data(withJSONObject: requestJSON)
    print(try? JSONSerialization.jsonObject(with: requestData!, options: []))
    var tokenURLRequest = URLRequest(url: tokenURL!)

    tokenURLRequest.httpMethod = "POST"
    tokenURLRequest.httpBody = requestData!
    tokenURLRequest.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "content-type")

    let tokenSession = URLSession.shared

    let tokenTask = tokenSession.dataTask(with: tokenURLRequest) { (data, response, error) in
        if error != nil {
            print("error getting your access token")
            print(error!.localizedDescription)
        }

        if let data = data{
            do{
                if let tokenInfo = try JSONSerialization.jsonObject(with: data, options: []) as? [String:Any]{
                    let token: String = tokenInfo["access_token"] as! String
                    print(token)
                }
            } catch {
                print("Error converting to JSON")
            }
        }
    }
    tokenTask.resume()
}

是的，我确信我会提供正确的客户凭证。任何帮助都将非常感谢，谢谢！

试试这个......

let clientId = "client_id"
let clientSecret = "client_secret"
let tokenURL = "https://api.yelp.com/oauth2/token"
let grantType = "client_credentials"


let url = NSURL(string: tokenURL as String );

let session = NSURLSession(configuration: NSURLSessionConfiguration.defaultSessionConfiguration())

let request = NSMutableURLRequest(URL: NSURL(string: tokenURL)!)
request.HTTPMethod = "POST";
request.HTTPShouldHandleCookies = true
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")


let postString = "client_id=" + clientId + "&client_secret=" + clientSecret + "&grant_type=" + grantType
request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)

let task: NSURLSessionDataTask = session.dataTaskWithRequest(request) { (data, response, error) -> Void in
    if let data = data {
        let response = NSString(data: data, encoding: NSUTF8StringEncoding)
        print(response)
    }
}
task.resume()

使用URLRequest返回iOS Yelp OAuth令牌检索＆＃34;找不到client_id或client_secret参数
