可见：
po error.localizedDescription 请求超时。
po error.code -1001

po error.userInfo{ NSErrorFailingURLKey = "http://123.56.109.92/refitcar/service.s?sn="; NSErrorFailingURLStringKey = "http://123.56.109.92/refitcar/service.s?sn="; NSLocalizedDescription = "\U8bf7\U6c42\U8d85\U65f6\U3002"; NSUnderlyingError = "Error Domain=kCFErrorDomainCFNetwork Code=-1001 \"\U8bf7\U6c42\U8d85\U65f6\U3002\" UserInfo={_kCFStreamErrorCodeKey=-2102, NSErrorFailingURLStringKey=http://123.56.109.92/refitcar/service.s?sn=, NSErrorFailingURLKey=http://123.56.109.92/refitcar/service.s?sn=, NSLocalizedDescription=\U8bf7\U6c42\U8d85\U65f6\U3002, _kCFStreamErrorDomainKey=4}"; "_kCFStreamErrorCodeKey" = "-2102"; "_kCFStreamErrorDomainKey" = 4;} |
所以使用 error.code是否等于 -1001 判断请求超时
