AWS S3下载iOS-请求超时

Question

I'm downloading around 400 files asynchronously in my iOS app using Swift from my bucket in Amazon S3, but sometimes i get this error for several of these files. The maximum file size is around 4 MBs, and the minimum is few KBs

Error is Optional(Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo={NSUnderlyingError=0x600000451190 {Error Domain=kCFErrorDomainCFNetwork Code=-1001 "(null)" UserInfo={_kCFStreamErrorCodeKey=-2102, _kCFStreamErrorDomainKey=4}}, NSErrorFailingURLStringKey= https://s3.us-east-2.amazonaws.com/mybucket/folder/file.html , NSErrorFailingURLKey= https://s3.us-east-2.amazonaws.com/mybucket/folder/file.html , _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-2102, NSLocalizedDescription=The request timed out.})

How can I prevent it?

Try to increase timeout:

let urlconfig = URLSessionConfiguration.default
urlconfig.timeoutIntervalForRequest = 300 // 300 seconds
