将字符串转换为整数或数字

Question

如何将字符串转换为 transfor dataweave 中的 number/integer。我尝试了以下

%dw 2.0
import * from dw::util::Coercions
output application/json
---
{
   "quoteId" : vars.setQuoteOppRecIds.Id,
   "productCode" : payload.ServiceTypeCode,
   "axSequenceNumber" : vars.counter as :number,
   "phaseLevel" : payload.PhaseLevel as :number,
   "activeInSOW" : if(payload.PhaseLevelActivateInSOW == "Yes") (toBoolean("true")) else (toBoolean("false")),
   "phaseLevelProject" : payload.PhaseLevelProject
}

但我收到类似 Invalid input ':', expected } or ',' for the object expression. (line 8, column 41): 的错误我尝试使用 toBoolean 函数将字符串转换为布尔值，它似乎工作正常。谁能告诉我 integer/number conversion

字符串中我缺少的是什么

DW 2 中的转换语法不同。您使用的代码来自 dw 1。在下面的 dw 2 中添加对类型转换的引用，并修复了您的 DW 脚本。

 %dw 2.0
import * from dw::util::Coercions
output application/json
---
{
   "quoteId" : vars.setQuoteOppRecIds.Id,
   "productCode" : payload.ServiceTypeCode,
   "axSequenceNumber" : vars.counter as Number,
   "phaseLevel" : payload.PhaseLevel as Number,
   "activeInSOW" : if(payload.PhaseLevelActivateInSOW == "Yes") (toBoolean("true")) else (toBoolean("false")),
   "phaseLevelProject" : payload.PhaseLevelProject
}
