iPhone - 解析charecter问题在JSON解析 [英] iPhone - Escape charecter issue in JSON parsing

问题描述

我正在使用客观的C JSON解析库并面临一些问题。我的Web服务返回JSON响应。当响应字符串中有转义字符时，我的解析器失败。以下是我从服务器收到的回复。

I am using objective C JSON parsing library and facing some issue . My web service returns the JSON response . My Parser fails when there is an escape character in the response string . Below is the response I am receiving from the server .

现在，如果观察者的行
item_name：花费$ 10andget $ 24worthofdonutsfromJim\'sDonutShop，则有一个转义字符 Jim \ Donut 。我的解析器无法解析这个异常。

Now if you observer the line "item_name" : "Spend$10andget$24worthofdonutsfromJim\'sDonutShop" , there is an escape character Jim\s Donut . My Parser fails to parse this with the exception.

 -JSONValue failed. Error trace is: (
    "Error Domain=org.brautaset.JSON.ErrorDomain Code=8 \"Illegal escape sequence '0x27'\" UserInfo=0x79cc420 {NSLocalizedDescription=Illegal escape sequence '0x27'}",
    "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Object value expected for key: item_name\" UserInfo=0x79cc510 {NSUnderlyingError=0x79cc470 \"Illegal escape sequence '0x27'\", NSLocalizedDescription=Object value expected for key: item_name}",
    "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Object value expected for key: parameters\" UserInfo=0x79cc5c0 {NSUnderlyingError=0x79cc540 \"Object value expected for key: item_name\", NSLocalizedDescription=Object value expected for key: parameters}"

我使用的是 JSON.h

NSDictionary * responseDic = [responseString JSONValue];

有人请帮我!! hank你!!

Somebody please help me !! Thank you !!

推荐答案

转义序列 \'不是有效的JSON。请参阅 json.org 。

The escape sequence \' is not valid JSON. See json.org.

您应该向Web服务的维护者提出错误。

You should raise a bug with the maintainers of the web service.

作为一个工作，您可以尝试用单个'替换序列，例如

As a work around, you might try replacing the sequence with a single ' e.g.

NSString* hackedString = [originalString stringByReplacingOccurrencesOfString: @"\\'" withString: @"'"];
