IOS json 解析遇到错误问题解决办法
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。
NSString * responseString = [request responseString]; responseString = [responseString stringByReplacingOccurrencesOfString:@"\r\n" withString:@""]; responseString = [responseString stringByReplacingOccurrencesOfString:@"\n" withString:@""]; responseString = [responseString stringByReplacingOccurrencesOfString:@"\t" withString:@""]; NSLog(@"responseString = %@",responseString); SBJsonParser *parser = [[[SBJsonParser alloc]init] autorelease]; id returnObject = [parser objectWithString:responseString]; NSDictionary *userInfo = nil; NSArray *userArr = nil; if ([returnObject isKindOfClass:[NSDictionary class]]) { if (userInfo) { [userArr release]; } userInfo = (NSDictionary*)returnObject; } else if ([returnObject isKindOfClass:[NSArray class]]) { userArr = (NSArray*)returnObject; } NSError* e = nil;
//系统自带的解析方式。
NSDictionary * userInfo = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableLeaves error:&e]; if (e) { NSLog(@"%@",e); }
