JSON验证错误

Question

[[["????","Hello world","N n h o sh ji "]],,"en"]     

这是json对象: contentOfResponseDataInJsonValue

我想得到????.怎么样？

NSString *returnStr=[[[[contentOfResponseDataInJsonValue JSONValue] objectAtIndex:0] objectAtIndex:0] objectAtIndex:0] ;

这样做,错误:

JSONValue失败了.错误跟踪是:("Error Domain = org.brautaset.JSON.ErrorDomain Code = 3 \"无法识别的前导字符\"UserInfo = 0x739f0c0 {NSLocalizedDescription =无法识别的前导字符}","错误域= org.brautaset.JSON.ErrorDomain代码= 3 \"解析数组时的预期值\"UserInfo = 0x739f140 {NSUnderlyingError = 0x739f120 \"无法识别的前导字符\",NSLocalizedDescription =解析数组时的预期值}"

Answer 1

看一下json.org的语法图表,我会说在数组中有两个逗号是没有关系的.你的JSON格式不正确.

[[["????","Hello world","N n h o sh ji "]],,"en"]
                                              ^^ not allowed!
