当收到302 AWS的S3 NSURLSessionDownloadTask被取消:AFNetworking 2.0 [英] AFNetworking 2.0: NSURLSessionDownloadTask is cancelled when received 302 to AWS S3
问题描述
我使用的README文件(从AFNetworking 2.0页)一个简单的例子来下载图像。一切工作正常的图像提供直接从我的网站,断绝。 但是,对于那些位于S3的web服务器返回302重定向以下错误:
I'm using a simple example from the README file (from AFNetworking 2.0 page) to download an image. All works fine for the images served directly from my web-sever. But for those located on the S3 the web-server returns 302 Redirect the following error:
Error Domain=NSURLErrorDomain Code=-999 "cancelled"
当我试图从S3下载图像(使用相同的code)直接(忽略重定向)我收到同样的错误。
When I try to download the image (using the same code) directly from the S3 (omitting the redirection) I receive the same error.
我已经检查了wget的实际图像的可用性。该图像是公开可用( https://youguide.s3.amazonaws.com/icons/user_96x96巴纽)。
I've checked the availability of the actual image with wget. The image is publicly available (https://youguide.s3.amazonaws.com/icons/user_96x96.png).
任何人都遇到类似的问题?
Anyone experience the similar problem?
推荐答案
我有同样的问题与S3,似乎已经解决了。 AFNetworking是在被取消请求认证挑战处理逻辑返回一个值
I was having the same problem with S3 and seem to have resolved it. AFNetworking was returning a value in the authentication challenge handling logic that was canceling the request.
通过告诉 AFURLSessionManager
如何处理我已经解决了这一问题验证挑战。
By telling the AFURLSessionManager
how to handle authentication challenges I've fixed the problem.
[manager setSessionDidReceiveAuthenticationChallengeBlock:^NSURLSessionAuthChallengeDisposition (NSURLSession *session, NSURLAuthenticationChallenge *challenge, NSURLCredential * __autoreleasing *credential) {
return NSURLSessionAuthChallengePerformDefaultHandling;
}];
