我在 Amazon AWS 中上传图像时遇到问题。这是我的代码:
import UIKit
protocol ContentUploaderDelegate {
func onContentLoadComplete(status:Bool,serverResponse:String)
}
class ContentUploader
{
let contentURL = "https:<MY URL>amazonaws.com/api/v1/contents"
var delegate:ContentUploaderDelegate?
func uploadImage(image:UIImage,xAuth:String,mimeType:String,imageName:String)
{
let url = NSURL(string: contentURL)
let request = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "POST"
let boundary = generateBoundaryString()
//define the multipart request type
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
request.setValue(xAuth, forHTTPHeaderField: "x-auth-token")
request.setValue("application/json", forHTTPHeaderField: "accept")
let image_data = UIImageJPEGRepresentation(image, 1.0)
if(image_data == nil)
{
return
}
let body = NSMutableData()
//name to save in server
let fname = imageName
let mimetype = mimeType
//define the data post parameter
body.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("Content-Disposition:form-data; name=\"test\"\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("hi\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("Content-Disposition:form-data; name=\"files\"; filename=\"\(fname)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("Content-Type: \(mimetype)\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(image_data!)
body.appendData("\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
//set the HTTPBody
request.HTTPBody = body
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request) {
(
let data, let response, let error) in
guard let _:NSData = data, let _:NSURLResponse = response where error == nil else {
print("error")
self.delegate?.onContentLoadComplete(false, serverResponse: (error?.description)!)
return
}
let dataString = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("success \(dataString)")
self.delegate?.onContentLoadComplete(true, serverResponse:dataString! as String)
}
task.resume()
}
private func generateBoundaryString() -> String
{
return "Boundary-\(NSUUID().UUIDString)"
}
以下委托(delegate)方法永远不会被调用。可能是什么原因?
func URLSession(session: NSURLSession,
task: NSURLSessionTask,
didReceiveChallenge challenge: NSURLAuthenticationChallenge,
completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?)
-> Void) {
let protectionSpace = challenge.protectionSpace
let theSender = challenge.sender
if protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust {
if (challenge.protectionSpace.host == "ec2-52-36-216-81.us-west-2.compute.amazonaws.com") {
if let theTrust = protectionSpace.serverTrust{
let theCredential = NSURLCredential(trust: theTrust)
theSender!.useCredential(theCredential, forAuthenticationChallenge: challenge)
return
}
}
}
theSender!.performDefaultHandlingForAuthenticationChallenge!(challenge)
return
}
}
我收到以下错误。知道为什么会出现此错误吗?
Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “.amazonaws.com” which could put your confidential information at risk."

最佳答案
Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “.amazonaws.com”
我认为通用名称有问题“.amazonaws.com”
NSErrorFailingURLKey=https://amazonaws.com/api/v1/contents,
NSErrorFailingURLStringKey=https://.amazonaws.com/api/v1/contents
错误消息中显示的 URL 似乎不是众所周知的端点。我希望在那里看到类似 https://ec2-2-2-2-2.compute-1.amazonaws.com
或其他完全合格的域名。
错误消息也证实了这一点。您正在连接主机,但证书上的名称不匹配。这就是假装为“.amazonaws.com”
错误的原因。
确认正确的端点,以及您的代码如何形成完整的 URL。
The following delegate method never gets called. What could be the reason?
错误发生在调用函数之前。由于证书错误, session 从未建立。
