如果在Alamofire中没有互联网连接时发生错误，我应该如何处理。我试过检查数据是否为零但不起作用。

How should I handle if there is an error occurs when there is no internet connection in Alamofire. I tried checking if data is nil or not but it does not work.

以下是我如何使用Alamofire

Below is how I use Alamofire

Alamofire.request(.POST, REGISTER_URL, parameters: parameters, encoding: .JSON, headers: getAuthenticationHeader()).response { (request, response, data, errorType) -> Void in let resultObject: APIResults = APIResults(JSONDecoder(data!)); let responseCode: Int = Int(resultObject.code!)!;// THIS CRASHES WHEN THERE IS NO INTERNET CONNECTION if (responseCode == 200) { available = true; } finished = true; }

推荐答案

我同意与@Shripada。首先，您应该使用Reachability检查连接性。 这里有一个Swift库： github/ashleymills/Reachability.swift

I agree with @Shripada. First you should use Reachability to check for connectivity. There is a Swift library here: github/ashleymills/Reachability.swift

此外，您可以使用其中一种Alamofire验证方法：

additionally you can use one of the Alamofire validation methods:

Alamofire.request(.POST, REGISTER_URL, parameters: parameters, encoding: .JSON, headers: getAuthenticationHeader()).validate(statusCode: 200 ..< 300).response { (request, response, data, error) -> Void in if error != nil { println("Server responded with: \(response.statusCode)") return } // Handle your response data here }
