概要:
Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn't be completed. (Cocoa error 3840.)" (Unescaped control character around character 1419.) UserInfo=0x1563cdd0 {NSDebugDescription=Unescaped control character around character 1419.}
之前解析json的时候都是标准格式,json数据当中没有 \n \r \t 等制表符。
今天在解析的时候发现json解析时好时坏,用在线json解析也米有问题。找了半天终于发现是制表符在作怪,由于标准的json解析是不允许有这几个制表符的。所以在收到保温的时候我们需要把这几个制表符给过滤掉。
