Javascript 如何使用Mirth Connect 3.4.1将json转换为HL7？

我现在定义了一个javascript转换器，但在转换时总是提示失败，代码如下：

var input = JSON.parse(connectorMessage.getRawData());
var patienId = input.PATIENT_ID;
var patientName = input.PATIENT_NAME;
var idCard = input.ID_NO;
var i = 1;
createSegment("MSH", msg, i++);
msg['MSH']['MSH.1']['MSH.1.1'] = '|';
msg['MSH']['MSH.2']['MSH.2.1'] = '^~\\&';
msg['MSH']['MSH.3']['MSH.3.1'] = patienId;
msg['MSH']['MSH.4']['MSH.4.2'] = patientName;
msg['MSH']['MSH.5']['MSH.5.1'] = idCard;

例外情况如下：

var input = JSON.parse(connectorMessage.getRawData());
var patienId = input.PATIENT_ID;
var patientName = input.PATIENT_NAME;
var idCard = input.ID_NO;
var i = 1;
createSegment("MSH", msg, i++);
msg['MSH']['MSH.1']['MSH.1.1'] = '|';
msg['MSH']['MSH.2']['MSH.2.1'] = '^~\\&';
msg['MSH']['MSH.3']['MSH.3.1'] = patienId;
msg['MSH']['MSH.4']['MSH.4.2'] = patientName;
msg['MSH']['MSH.5']['MSH.5.1'] = idCard;

上述代码中的问题始于

createSegment

code。在那之前一切都很好

在出站转换器中，创建一个虚拟消息模板，如下所示： 这只是一个同名模板，您正在定义它来创建HL7段范围

MSH|^~\&|||||||||||
PID||||||||||||||||||||
PD1|||||

考虑到您收到类似以下内容的JSON：

{
    "PATIENT_ID": "XXXX",
    "PATIENT_NAME": "John",
    "ID_NO": "454141541"
}

我认为这种语法不正确

createSegment（'MSH'，msg，I++）
我已修改了您在上面提供的代码：

var input = JSON.parse(connectorMessage.getRawData());
var patienId = input.PATIENT_ID;
var patientName = input.PATIENT_NAME;
var idCard = input.ID_NO;
msg=tmp;
createSegment('MSH', msg);
msg['MSH']['MSH.1']= "|";
msg['MSH']['MSH.2']= "^~\\&";
msg['MSH']['MSH.3']= patienId;
msg['MSH']['MSH.4']= patientName;
msg['MSH']['MSH.5']= idCard;

您还可以按照您建议的方式在HL7消息中增加计数器。参考柜台：

tmp中有什么？@brijexecon tmp是出站消息的欢乐消息对象。msg if用于入站消息
