`awk`中我的自定义函数`json_stringify`有问题答案

【问题标题】：problem with my custom function `json_stringify` in `awk``awk`中我的自定义函数`json_stringify`有问题
【发布时间】：2022-09-23 02:07:48
【问题描述】：

我编写了一个 shell 函数，它使用 awk 将 UTF-8 编码字符串转换为 JSON 字符串。

json_stringify() {

    LANG=C awk \'

        BEGIN {
            for ( i = 1; i < ARGC; i++ )
                print json_stringify(ARGV[i])
        }

        function json_stringify( str, _str, _out ) {

            if( ! (\"\\\\\" in _ESC_) )
                for ( i = 1; i <= 127; i++ )
                    _ESC_[ sprintf( \"%c\", i) ] = sprintf( \"\\\\u%04x\", i )

            _str = str
            _out = \"\\\"\"

            while ( match( _str, /[\\\"\\\\[:cntrl:]]/ ) ) {
                _out = _out substr(_str,1,RSTART-1) _ESC_[substr(_str,RSTART,RLENGTH)]
                _str = substr( _str, RSTART + RLENGTH )
            }

            return _out _str \"\\\"\"
        }
    \' \"$@\"
}

感觉就像我错过了一些微不足道的事情，因为当我运行时（在 bash 中）：

json_stringify \'A\"B\' \'C\\D\' $\'\\b \\f \\t \\r \\n\'

我得到：

\"A\\u0022B\"

而我的预期输出是：

\"A\\u0022B\"
\"C\\u005cD\"
\"\\u0008 \\u000c \\u0009 \\u000d \\u000a\"

我的代码中可能有什么问题？

【解决方案1】：

我看到的一个问题是在BEGIN/for 循环和function/for 循环中双重使用i 作为循环变量，并且因为i 在函数中没有被声明为“本地”，所以你最终得到的只是i 的一个实例用于整个脚本。最终结果是函数将i 推送到127，这远远超出ARGC，因此BEGIN 块仅循环一次（i=1），因为在第二个循环i=127。

两个可能的修复：

将i 声明为函数的本地，例如：

function json_stringify( str, _str, _out, i ) {

或在其中一个循环中使用不同的循环变量（例如，j），例如：

# in the BEGIN block:

for ( j = 1; j < ARGC; j++ )
    print json_stringify(ARGV[j])

# or in the function:

for ( j = 1; j <= 127; j++ )
     _ESC_[ sprintf( "%c", j) ] = sprintf( "\\u%04x", j )

测试每个可能的修复可以让我生成：

"A\u0022B"
"C\u005cD"
"\u0008 \u000c \u0009 \u000d \u000a"

谢谢markp-fuso，我完全忽略了i 变量。现在代码可以在 GNU awk 上正常工作，但我在旧版 BSD 上遇到了一个奇怪的问题（请参阅 stackoverflow.com/q/73778696/3387716 ）

【解决方案2】：

如果UTF-8 输入字符串不包含任何NUL 字节，则这是一个可以与任何符合POSIX 的系统一起使用的shell 函数：

json_stringify() {

    LANG=C awk '

        BEGIN {
            for ( i = 1; i < ARGC; i++ )
                print json_stringify(ARGV[i])
        }

        function json_stringify( str, _str, _out, _i) {

            if( ! ("\\" in _ESC_) )
                for ( _i = 1; _i <= 127; _i++ )
                    _ESC_[ sprintf( "%c", _i) ] = sprintf( "\\u%04x", _i )

            _str = str
            _out = "\""

            while ( match( _str, /[\001-\037\042\134\177]/ ) ) {
                _out = _out substr(_str,1,RSTART-1) _ESC_[substr(_str,RSTART,RLENGTH)]
                _str = substr( _str, RSTART + RLENGTH )
            }

            return _out _str "\""
        }
    ' "$@"
}

json_stringify "$@"

评论：我已经定义了 awk 函数 json_stringify 因为有时你可能想要 JSON 转义参数中的字符串（如这里），有时你可能想要参数中文件的内容等等......可以用于您拥有的任何用例可能是最通用的解决方案。

在旁边：我不会转义非 BMP 字符（并计算它们的 UTF-16 代理对），因为 RFC 不需要它：

所有 Unicode 字符都可以放在引号内，除了必须转义的字符：引号、反斜线和控制字符（U+0000 到 U+001F）。

@Fravadona：这是一种轻松映射所有字节的简单方法-不会生成/抑制单个错误/警告消息

表ordU8[] 返回的链的第一个整数是预先计算的偏移量，以简化从其组成字节对UTF-8 代码点的反向计算：
\b、\t、\n、\v、\f、\r、\033 和 \177 的行看起来错乱了，因为它们的底层字节正在做他们定义要做的事情
