Apache NiFi 文本替换

Question

用属性值替换 []（包括方括号）中的字符串的最佳方法是什么？

{ "VoiceMessageTemplateEnglish" : "Hello, this is [LocationName] calling to confirm an appointment for [Name] on [AppointmentDate] at [AppointmentTime] with [Name]. Please press 1 To confirm, Press 2 To Cancel", }

我尝试在 JS 中使用 ExecuteScript 处理器，但没有成功。

谢谢！

Answer 1

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

Answer 2

最后我用JS解决了问题：

感谢@daggett 为我指明了正确的方向

var 流文件 = session.get(); 如果（流文件！=空）{

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();

}
