里面的dataTaskWithRequest不是执行。 在Swift中打开API

当我用POSTMAN打相同的数据我得到所需的响应。 但在我的函数内dataTaskWithRequest我没有得到任何回应。

func sendData (){ let url = NSURL(string: "http://www.example.com/quiz-school/mobileData/request.php?request=QuizTotal&module=PQ")! let request = NSMutableURLRequest(URL: url) request.HTTPMethod = "POST" request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(dict, options: NSJSONWritingOptions()) request.setValue("application/json", forHTTPHeaderField: "Content-Type") let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data, response, error in if(error != nil){ print(error) return } ((response as! NSHTTPURLResponse).statusCode) } task.resume() } 

在数据任务

数据任务后

邮递员回复 谢谢任何帮助将不胜感激。

我正在发送的字典

 { data = ( { answer = ( 9353091 ); question = 31675931; }, { answer = ( 9353101 ); question = 31675936; }, { answer = ( 9353111 ); question = 31675941; }, { answer = ( 9353121 ); question = 31675946; }, { answer = ( 9353131 ); question = 31675951; }, { answer = ( 9353141 ); question = 31675954; }, { answer = ( 9353151 ); question = 31675961; }, { answer = ( 9353279 ); question = 31676023; }, { answer = ( 9353289 ); question = 31676026; }, { answer = ( 9353299 ); question = 31676031; } ); end = 5565665; quizId = 1206500; start = 5565656; }

根据我们的讨论发布代码在我身边工作：

 //MARK: URLRequest func sendData (){ var dict = [String:AnyObject]() dict = [ "data" : [ [ "answer" : [9353091], "question" : 31675931 ], [ "answer" : [9353101], "question" : 31675936 ] ], "end" : 5565665, "quizId" : 1206500, "start" : 5565656 ] print(dict) let url = NSURL(string: "http://www.proprofs.com/quiz-school/mobileData/request.php?request=QuizTotal&module=PQ")! let request = NSMutableURLRequest(URL: url) request.HTTPMethod = "POST" request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(dict, options: NSJSONWritingOptions()) request.setValue("application/json", forHTTPHeaderField: "Content-Type") let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data, response, error in if(error != nil){ print("ERRORRRRRRR : \(error)") return } print("RESPONSEEEEE : \(response)") do { let dic = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? [String:AnyObject] print("DIIIIIIIC \(dic)") }catch { print("adsfdasfdsfdsafdsfadsfs") } ((response as! NSHTTPURLResponse).statusCode) } task.resume() } 

最终编辑：

OP在上述代码中没有问题。 经过几个小时的讨论并与他聊天，我发现错误出现在didSelectRowAtIndexPath ，在sendData:方法被调用后，项目立即崩溃，因此没有收到服务器的响应。
