我在新升级到Swift 2.0的项目中依次执行以下两个调用。
let session = NSURLSession.sharedSession()
authRequest.HTTPMethod = "POST"
authRequest.HTTPBody = authData
authRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")
authRequest.addValue("close", forHTTPHeaderField: "Connection")
authRequest.addValue("application/json", forHTTPHeaderField: "Accept")
let authTask = session.dataTaskWithRequest(authRequest, completionHandler: { (data : NSData?, response : NSURLResponse? , error : NSError?) -> Void in
print("Response: \(response)")
print("Error: \(error)")
let strData = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("Body: \(strData)")
if let httpResponse = response as? NSHTTPURLResponse
{
if 200 ... 299 ~= httpResponse.statusCode
{
do
{
result = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableLeaves) as! Dictionary
credentials.ClientId = (result["client_id"] as String?)!
credentials.ClientSecret = (result["client_secret"] as String?)!
credentials.Username = userDetail.Username
credentials.Password = userDetail.Password
completionHandler(result: true)
}
catch {
}
}
else
{
self.RemoveInvalidUserCredentials()
completionHandler(result: false)
}
}
})
authTask.resume()
接下来是:
let session = NSURLSession(configuration: NSURLSessionConfiguration.defaultSessionConfiguration())
session.configuration.URLCache = nil
session.configuration.HTTPMaximumConnectionsPerHost = 1
tokenRequest.HTTPBody = tokenData
tokenRequest.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
tokenRequest.addValue("close", forHTTPHeaderField: "Connection")
tokenRequest.addValue("Basic " + (credentials.encodedClientIdAndSecret() as String), forHTTPHeaderField: "Authorization")
let tokenTask = session.dataTaskWithRequest(tokenRequest, completionHandler: {(data : NSData?, response : NSURLResponse? , error : NSError?) -> Void in
print("Response: \(response)")
print("Error: \(error)")
let strData = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("Body: \(strData)")
if let httpResponse = response as? NSHTTPURLResponse {
if 200 ... 299 ~= httpResponse.statusCode
{
do
{
result = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableLeaves) as! Dictionary
credentials.TokenType = (result["token_type"] as! String?)!
credentials.Token = (result["access_token"] as! String?)!
completionHandler(result: true)
}
catch{}
}
}
})
tokenTask.resume()
第一个代码块执行正确,并返回以下内容:
Response: Optional(<NSHTTPURLResponse: 0x14ffe3e60> { URL: <URL>/authorize } { status code: 200, headers {
"Cache-Control" = "no-cache";
"Content-Length" = 115;
"Content-Type" = "application/json; charset=utf-8";
Date = "Tue, 29 Sep 2015 14:17:52 GMT";
Expires = "-1";
Pragma = "no-cache";
Server = "Microsoft-IIS/7.5";
"Set-Cookie" = ".AspNet.ApplicationCookie=E98BMJ5l56psnnJZRy2fyhRTWVYqw4aJsFqPeV1ktkJGi5_frTJ9-8pbp28TcDAn9ISFj_LqwFwOV7WhP1mfTVPktTGTs2Dr5-hvmnISxFVRc1Rg9CcYf3p-Cbn1w6qOEyuXco9PCmCnlsf54KPuSY6Z7FEcUgOyg2nq5oDyamfB_Y4b1dI-7cIZ3LB6ehoI50rIbc2ca7L7f73H1rhbsmuLRarBYsYehSRHRuKs9ec5-XuN0P1W6yqiQ3OOJMayPmmbi6y4uIhBUu0zoRC2v3k9usmRjubxGy2hqf6n0baTOIDokav0wQq_smR9qDA6nNh09YTS1Mzvf0iQPS2YJa7QrnERlNSixDROhkQVLC8hc3GV8jc9_7iGUhJzLgeVzhnjnVeB7Z311QLcXxGonEzzcWAzPu29tm2LkZgdte4J0kQHc-iTiNjSbgBqV2zVH9v_0JHtZCFGdSxSGptXGfsPr5O9M-EyVX2UNXxIsVI-hfv3p8-_igV96phbWsvWyqyYhVMQ8v61vHxfO2CFIQ; path=/; secure; HttpOnly";
"X-Powered-By" = "ASP.NET";
然而第二个错误如下:
我无法访问服务器,并尝试使用不同的会话和相同的共享会话发送请求。错误域=NSURLErrorDomain,代码=-1005,“网络连接丢失。” UserInfo={NSUnderlyingError=0x14ffe3cc0 {错误域=kCFErrorDomainCFNetwork,代码=-1005“(null)” UserInfo={_kCFStreamErrorCodeKey=-4,_kCFStreamErrorDomainKey=4}},NSErrorFailingURLStringKey=https://test.acumentive.com/tagmanager/api/v1/tokens,NSErrorFailingURLKey=https://test.acumentive.com/tagmanager/api/v1/tokens,_kCFStreamErrorDomainKey=4,_kCFStreamErrorCodeKey=-4,NSLocalizedDescription=网络连接丢失。}
有什么想法吗?
