what is kCFErrorDomainCFNetwork Code=303

问题:

I tried to post my textFiled data to Server.but when posting I got this error:

Error: Error Domain=kCFErrorDomainCFNetwork Code=303 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 303.)" UserInfo=0x13786c60 {NSErrorFailingURLKey=http://192.168.3.125:8090/SaveDollar/rest/deals/add, NSErrorFailingURLStringKey=http://192.168.3.125:8090/SaveDollar/rest/deals/add}

I do not understand this error.

回答1:

Is a parsing error from the server, when its response can't be parsed. You can look up the error codes in the CFNetworkErrors reference.

Make sure you set HTTPMethod to POST

回答2:

kCFErrorHTTPParseFailure      = 303,

The HTTP server response could not be parsed.
