無法調用常規的閉包

[英]Unable to call a groovy closure

我正在使用ws-lite自動執行Web服務測試,並且希望對生成的xml請求具有更靈活的控制。

基本上,請求正文是一個常規的閉包,將傳遞給MarkupBuilder以創建SOAP消息。

這是我要實現的示例(示例取自https://github.com/jwagenleitner/groovy-wslite ):

@Grab(group='com.github.groovy-wslite', module='groovy-wslite', version='1.1.0')
import wslite.soap.*

def client = new SOAPClient('http://www.holidaywebservice.com/Holidays/US/Dates/USHolidayDates.asmx')
def month = ["Feb"]

def response = client.send(SOAPAction:'http://www.27seconds.com/Holidays/US/Dates/GetMothersDay') {
    body {
        GetMothersDay('xmlns':'http://www.27seconds.com/Holidays/US/Dates/') {
            year(2011)
            month.each{ a = null ->
                                        if (a != null){
                                            "month"(a)
                                        }
                                    }
        }
    }
}

assert "2011-05-08T00:00:00" == response.GetMothersDayResponse.GetMothersDayResult.text()
assert 200 == response.httpResponse.statusCode
assert "ASP.NET" == response.httpResponse.headers['X-Powered-By']

在上面的示例中,我可以使用指定的一個或多個值創建月份標簽。

但是,如果我將其更改為:

@Grab(group='com.github.groovy-wslite', module='groovy-wslite', version='1.1.0')
import wslite.soap.*

def client = new SOAPClient('http://www.holidaywebservice.com/Holidays/US/Dates/USHolidayDates.asmx')
def month_cl = { a -> "month"(a) }

def response = client.send(SOAPAction:'http://www.27seconds.com/Holidays/US/Dates/GetMothersDay') {
    body {
        GetMothersDay('xmlns':'http://www.27seconds.com/Holidays/US/Dates/') {
            year(2011)
            month_cl("Feb")
        }
    }
}

assert "2011-05-08T00:00:00" == response.GetMothersDayResponse.GetMothersDayResult.text()
assert 200 == response.httpResponse.statusCode
assert "ASP.NET" == response.httpResponse.headers['X-Powered-By']

我將缺少一個方法異常。

我不太明白為什么我不能只調用像這樣的常規閉包?

必須將month_cl關閉的委托設置為當前/父委托(在這種情況下,它作為參數傳遞給GetMothersDay )。 嘗試:

body {
    GetMothersDay('xmlns':'http://www.27seconds.com/Holidays/US/Dates/') {
        year(2011)
        month_cl.delegate = delegate
        month_cl("Feb")
    }
}

獲取MissingMethodException是很正常的,因為閉包month_cl正在調用不存在的month方法。 為此(以您的方式),應將Closure c傳遞給month_cl並在參數a上調用它,如下所示:

def month_cl = { a, Closure c -> c(a) }

並使用新的實現, month_cl("Feb")變為month_cl("Feb") { "month" } ,結果為"month"("Feb")

這是一個工作示例:

@Grab(group='com.github.groovy-wslite', module='groovy-wslite', version='1.1.0')
import wslite.soap.*

def client = new SOAPClient('http://www.holidaywebservice.com/Holidays/US/Dates/USHolidayDates.asmx')
def months = ["Feb"]
def month_cl = { m, Closure c -> return c(m) }

def response = client.send(SOAPAction:'http://www.27seconds.com/Holidays/US/Dates/GetMothersDay') {
    body {
        GetMothersDay('xmlns':'http://www.27seconds.com/Holidays/US/Dates/') {
            year(2011)
            month_cl("Feb") { "month" }  // -> month("Feb")
        }
    }
}

assert "2011-05-08T00:00:00" != response.GetMothersDayResponse.GetMothersDayResult.text()
assert 200 == response.httpResponse.statusCode
assert "ASP.NET" == response.httpResponse.headers['X-Powered-By']
