自從升級到9.1後，斯威夫特語法的變化對URL的請求，我已經得到發出請求到我的API錯誤。例如，這個簡單地嘗試登錄的POST請求。我可以直接在API（Strongloop Loopback）Explorer界面中直接登錄，但不能從Swift登錄。我得到這個錯誤：錯誤「操作無法完成。沒有這樣的文件或目錄」
The operation couldn’t be completed. No such file or directory
這裏是我的代碼如下所示：
func performLoginRequestWithURL(url: NSURL, email: String, password: String) {
let bodyData = "email=\(email)&password=\(password)"
let request: NSMutableURLRequest = NSMutableURLRequest(URL: url)
let session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding)
let task = session.dataTaskWithRequest(request, completionHandler: {
data, response, error -> Void in
if let error = error {
let errString = error.localizedDescription
NSNotificationCenter.defaultCenter().postNotificationName(self.lh, object: nil, userInfo: ["Result": errString])
print(error.localizedDescription)
} else if data != nil {
let json = NSString(data: data!, encoding: NSUTF8StringEncoding) as! String
if let dictionary = JSON().parseJSON(json) as [String: AnyObject]? {
let accesstoken = dictionary["id"] as! String
let id = dictionary["userId"] as! Int
// MARK: - Store UID & AccessToken
NSUserDefaults.standardUserDefaults().setBool(true, forKey: "userLoggedIn")
NSUserDefaults.standardUserDefaults().setInteger(id, forKey: "userId")
NSUserDefaults.standardUserDefaults().setObject(accesstoken, forKey: "accessToken")
NSUserDefaults.standardUserDefaults().synchronize()
NSNotificationCenter.defaultCenter().postNotificationName(self.lh, object: nil, userInfo: ["Result": "Success"])
}
}
})
task.resume()
}
下面是它曾經是什麼樣子回來時，它的工作，但他們貶值sendAsynchronousRequest方法：
func performLoginRequestWithURL(url: NSURL, email: String, password: String) {
let bodyData = "email=\(email)&password=\(password)"
var request: NSMutableURLRequest = NSMutableURLRequest(URL: url)
request.HTTPMethod = "POST"
request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding)
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()){
response, data, error in
if let error = error {
let errString = error.localizedDescription
NSNotificationCenter.defaultCenter().postNotificationName(self.lh, object: nil, userInfo: ["Result": errString])
} else if data != nil {
let json = NSString(data: data, encoding: NSUTF8StringEncoding) as! String
if let dictionary = JSON().parseJSON(json) as [String: AnyObject]? {
let accesstoken = dictionary["id"] as! String
let id = dictionary["userId"] as! Int
var results = [String: AnyObject]()
results = ["at": accesstoken, "id": id]
// MARK: - Store UID & AccessToken
NSUserDefaults.standardUserDefaults().setBool(true, forKey: "userLoggedIn")
NSUserDefaults.standardUserDefaults().setInteger(id, forKey: "userId")
NSUserDefaults.standardUserDefaults().setObject(accesstoken, forKey: "accessToken")
NSUserDefaults.standardUserDefaults().synchronize()
NSNotificationCenter.defaultCenter().postNotificationName(self.lh, object: nil, userInfo: ["Result": "Success"])
}
}
}
}
