如何从ASP.NET JSON日期格式转义反斜线prevent JSONKit？ [英] How to prevent JSONKit from escaping backslash from ASP.NET JSON date format?

问题描述

我使用 JSONKit 来连接一个ASP之间code /德code JSON .NET RESTful服务。

I am using JSONKit to encode/decode JSON between an ASP.NET RESTful service.

由服务使用的日期格式谈到的此处，看起来像：

The date format used by the service is talked about here and looks like:

"\/Date(1198908717056)\/"

问题是，当JSONKit处理一个字符串，它看起来像这样最终的结果看起来是这样上面，它避开反斜杠：

The problem is that when JSONKit processes a string that looks like above it escapes the backslash so the end result looks like this:

"\\/Date(1198908717056)\\/"

该JSON规范说，你可以选择逃避正斜杠（/），所以应该JSONKit间preT在\\ /，而不要逃避反斜杠。

有谁知道从何时其次是像上面的ASP.NET JSON日期格式的情况下，正斜杠转义反斜线办法prevent JSONKit？

Does anyone know of a way to prevent JSONKit from escaping the backslash when it is followed by a forward slash like the case above for ASP.NET JSON date formats?

推荐答案

编辑：忘记了previous答案。正如约翰所提到的，它可能是不正确的，有副作用。约翰的致力于一个变化实现所谓的选项 JKSerializeOptionEscapeForwardSlashes 这应该解决您的问题。

Forget the previous answer. As John mentioned, it’s probably incorrect and have side effects. John’s committed a change that implements an option called JKSerializeOptionEscapeForwardSlashes which should solve your problem.

尽管在JSONKit解析器似乎处理 \\ / ，它看起来像发电机没有。在 jk_en code_add_atom_to_buffer（）：

Even though the parser in JSONKit seems to handle \/, it looks like the generator doesn’t. In jk_encode_add_atom_to_buffer():

if(JK_EXPECT_F(utf8String[utf8Idx] >= 0x80U)) { encodeState->atIndex = startingAtIndex; goto slowUTF8Path; }

这是一个非ASCII字符，进入 slowUTF8Path 。

if(JK_EXPECT_F(utf8String[utf8Idx] <  0x20U))

这是一个控制字符（如 \\ n 或 \\ t ），逃吧。

if(JK_EXPECT_F(utf8String[utf8Idx] == '\"') || JK_EXPECT_F(utf8String[utf8Idx] == '\\')) { encodeState->stringBuffer.bytes.ptr[encodeState->atIndex++] = '\\'; }

这是一个双引号或反斜杠，逃避它 - 而这就是错误，因为它没有考虑到 \\ /

我已经修补JSONKit.m，使其执行以下操作：

I’ve patched JSONKit.m so that it does the following:

if(JK_EXPECT_F(utf8String[utf8Idx]) == '\\' && JK_EXPECT_F(utf8String[utf8Idx+1]) == '/') {
    encodeState->stringBuffer.bytes.ptr[encodeState->atIndex++] = '\\';
    encodeState->stringBuffer.bytes.ptr[encodeState->atIndex++] = '/';
    utf8Idx++;
}
else if(JK_EXPECT_F(utf8String[utf8Idx] == '\"') || JK_EXPECT_F(utf8String[utf8Idx] == '\\')) { encodeState->stringBuffer.bytes.ptr[encodeState->atIndex++] = '\\'; }
else encodeState->stringBuffer.bytes.ptr[encodeState->atIndex++] = utf8String[utf8Idx];

和我的测试程序正确生成的JSON片段为您的字符串：

and my test program correctly generates the JSON fragment for your string:

NSString *test = @"\\/Date(1198908717056)\\/";
NSLog(@"%@", [test JSONString]);

输出：

"\/Date(1198908717056)\/"

如果没有我的补丁，该程序的输出：

Without my patch, the program outputs:

"\\/Date(1198908717056)\\/"

不过，我建议你文件，JSONKit 的bug报告。约翰肯定是解决这个问题的最佳人选，而且JSONKit是过于优化了我在这个补丁的信心;我不是在所有熟悉JSONKit。随意给他参考这个帖子。

That said, I recommend you file a bug report with JSONKit. John is certainly the best person to fix this and JSONKit is far too optimised for me to have confidence in this patch; I’m not familiar with JSONKit at all. Feel free to refer him to this post.
