DataWeave 2.0 反斜杠转义

Question

如何在 DataWeave 2.0 中获得单个反斜杠？

%dw 2.0
output application/json
---
{
  "attempt1": "\String",
  "attempt2": "\\String"
}

返回：

{
  "attempt1": "\\String",
  "attempt2": "\\String"
}

Answer 1

看起来你的输出是一个 json 并且在json中 \\ 总是需要在一个字符串中转义。 这就是为什么你总是会看到两个\\

Answer 2

如果输出是@machaval所说的json，看来它将始终解析为偶数。

调整mulesoft文档： https ://docs.mulesoft.com/mule-runtime/4.1/dataweave-language-introduction#examples

%dw 2.0
output application/json
---
{
    "a": "something",
    "b": "dollar sign (\$)",
    "c": 'single quote (\')',
    "c": "double quote (\")",
    "e": 'backtick (`)',
    "f": "backslash(\)",
    "g": "backslashOdd(\\\)",
    "h": "backslashEven(\\\\\\)"
}

产生：

{
  "a": "something",
  "b": "dollar sign ($)",
  "c": "single quote (')",
  "c": "double quote (\")",
  "e": "backtick (`)",
  "f": "backslash(\\)",
  "g": "backslashOdd(\\)",
  "h": "backslashEven(\\\\)"
}

如果您得到更好的答案，请偏爱此问题。 我想我最终在过去使用了toString（）。replace（）
