由于信号命令失败：分段错误：11：alamofire post

Question

我正在使用xcode 7.3和swift 2.3。为了建立网络连接，我使用'Alamofire'，'〜> 3.4.1'。直到我执行归档选项时，我才会遇到问题。我正在和Xcode的标记在--->标记这个错误

命令失败，原因是信号：分段故障：11

class func post(url: String, headers:[String: String], parameters:[String: AnyObject], success:(AnyObject)->(), failure:(AnyObject)->()) ->() { 
--->  Alamofire.request(.POST, 
      url, 
      headers:headers, 
      parameters:parameters,encoding:.URL) 
      .debugLog() 
      .validate(statusCode: 200..<300) 
      .responseString { response in 

       response.debugLog() 
       switch response.result{ 
       case .Success(_): 
        //print(response) 
        let httpResponseBody = response.result.value! as String 
        success(httpResponseBody) 

       case .Failure(_): 
        let error = response.result.error 
        //print(error) 
        failure(error!) 


       } 
     } 

Answer 1

浪费4小时调试错误的原因后，我终于身影这段代码导致了问题。

extension Request { public func debugLog() -> Self { //#if DEBUG debugPrint(self) //#endif return self } }

然后我从

class func post(url: String, headers:[String: String], parameters:[String: AnyObject], success:(AnyObject)->(), failure:(AnyObject)->()) ->() { 
--->  Alamofire.request(.POST, 
      url, 
      headers:headers, 
      parameters:parameters,encoding:.URL) 
      // .debugLog() 
      .validate(statusCode: 200..<300) 
      .responseString { response in 

       response.debugLog() 
       switch response.result{ 
       case .Success(_): 
        //print(response) 
        let httpResponseBody = response.result.value! as String 
        success(httpResponseBody) 

       case .Failure(_): 
        let error = response.result.error 
        //print(error) 
        failure(error!) 


       } 
     } 

注释的.debug（）
