Question

是否可以仅使用Logic应用程序中WDL的函数来随机化数组的元素？

Answer 1

在LogicApp中没有直接的随机方法。

我想您可以提出一些可以完全在Logic App中对列表进行伪随机化的模式，但是....

处理此问题的更“正确”方法是使用Function。

Answer 2

假设您有1到10个数组

您创建空的随机数组变量

和一个临时值（在以后的步骤中使用，因为不允许自引用）

然后您像这样创建直到循环

直到条件为“等于10”且表达式为

length(variables('Randomized'))

如果条件为“等于1”和表达式

rand(0,2)

如果为真，路径已将 temp 变量设置为

union(variables('Randomized'), createArray(variables('Array')[iterationIndexes('Until')]))

并且如果为假，路径已将 temp 变量设置为

union(createArray(variables('Array')[iterationIndexes('Until')]), variables('Randomized'))

在条件语句中，将随机变量设置为 temp 值

在最后一次迭代之后，您将获得随机的输入表
