Hello, I’m to trying retrieve the diagram XML via the [REST] API, like this:
I do get the data from Postman, but when I use it in Springboot:
var settings = {
"url": "http://10.168.5.22:8180/rest/process-definition/key/VentaNueva/xml",
"method": "GET",
"timeout": 0,
};
$.ajax(settings).done(function(response) {
viewer.importXML(response, function(err) {
if (err) {
console.log(err);
} else {
console.log('Flujo Renderizado');
}
});
});
----------------------------------------------------------------------------------------------------------------
Im getting this:
Error: “required args <xml=string>”
@Minrg when you get processdefinition xml, the api will return serialized bpmn xml string. If you are using spring boot then you can easily obtain a BpmnModelInstance from the string.
JsonNode bpmnData = new ObjectMapper().readTree(response.body().byteStream());
String bpmn20XmlString = bpmnData.get("bpmn20Xml").asText();
InputStream bpmn20XMLStream = new ByteArrayInputStream(bpmn20XmlString.getBytes(StandardCharsets.UTF_8));
BpmnModelInstance bpmnModelInstance = Bpmn.readModelFromStream(bpmn20XMLStream);
For more details on reading bpmn model:
