Question

我有类似的东西

def firstName = apiAccessor.getIdentityAPI().getUser(commentInput.authorId).firstName
def lastName = apiAccessor.getIdentityAPI().getUser(commentInput.authorId).lastName
commentVar.authorFullName = firstName + " " + lastName

它可以工作，但是我想用语句使同样的事情变得有用。

我尝试过，但是不起作用：

with(apiAccessor.getIdentityAPI().getUser(commentInput.authorId)) {
    commentVar.authorFullName = it.firstName + " " + it.lastName
}

看起来如何？

您调用.with{ ... }（或.tap{ }) right on the thing you want to use inside the closure. It's an delegate, so you don't even have to use it`（或命名参数）。

您的代码非常接近：

def data = [a: [b: [c: [firstName: "X", lastName: "Y"]]]]
def commentVar = [:]

data.a.b.c.with {
    commentVar.authorFullName = firstName + " " + lastName
}

assert commentVar.authorFullName == "X Y"

在这种情况下如何与with语句一起使用？
