Apache NiFi文本替换

Question

用属性值替换including the brackets中的字符串的最佳方法是什么？

{ "VoiceMessageTemplateEnglish“：”你好，我是LocationName打电话来确认AppointmentDate上有名字的约会。请按1确认，按2取消“，}

我尝试在JS中使用ExecuteScript处理器，但是没有任何运气。

谢谢!

Answer 1

最后我使用JS解决了这个问题：

谢谢达吉特为我指明了正确的方向

var flowFile = session.get()；if (flowFile != null) {

var lclAppointmentDate = flowFile.getAttribute("AppointmentDate");
var lclAppointmentStartTime = flowFile.getAttribute("AppointmentStartTime");
var lclName = flowFile.getAttribute("Name");
var lclVoiceMailTemplate = flowFile.getAttribute("VoiceMailTemplate");



if (lclVoiceMailTemplate != null){
    lclVoiceMailTemplate  = lclVoiceMailTemplate
                       .replace('[Name]', lclName)
                       .replace('[AppointmentDate]', lclAppointmentDate)
                       .replace('[AppointmentTime]', lclAppointmentStartTime);
    flowFile = session.putAttribute(flowFile, "FinalVoiceMailTemplate", lclVoiceMailTemplate);
}
session.transfer(flowFile, REL_SUCCESS);
session.commit();

}

nifi 1.5.0中的处理器ExecuteGroovyScript

def ff = session.get()
if(!ff)return

def attr = ff.getAttributes()
def text = ff.read().getText("UTF-8")
text = text.replaceAll( /\[(\w+)\]/ ) {  attr[it[1]] ?: "noValue" }

ff.write("UTF-8", text)

REL_SUCCESS << ff
