Hi,
I currently try to use a POST request to send json data to a service on the TWX platform.
I successed to invoke the service, i can see it in the script log.
The thing invoked take 2 optionnal inputs :
But here is the problem : both of these inputs stay at undefined state, and i didn't manage to get the data....
Here is the Java code used to send the request :
HttpsURLConnection conn =
(HttpsURLConnection) url.openConnection();
byte[] postData = jsonData.getBytes(StandardCharsets.UTF_8);
int postDataLength = postData.length;
conn.setRequestMethod("POST");
conn.setRequestProperty("x-thingworx-session", "true");
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty( "Content-Length", Integer.toString( postDataLength ));
conn.setRequestProperty("appKey", appKey);
// Create the form content
conn.setDoOutput(true);
DataOutputStream out = new DataOutputStream(conn.getOutputStream());
out.write(postData);
out.flush();
out.close();
if (conn.getResponseCode() != 200) {
throw new IOException(conn.getResponseMessage());
}
Can comeone help me to understand why my jsonObj is still undefined ? The JsonData is a String got from a JSONObject.
Thanks,
Kevin B.
Solved! Go to Solution.
Kevin, I'm not sure if you did this already, but please do take a look at this knowledgebase article link on how to post json content to a service.

Thanks, is didn't found this article before.
I tryed so to build my string manually :
int id = 0;
String str="";
str+="{\"jsonObj\":\"{\"jsonObj\":{"; // Let's append now propertyName : pName, propertyValue : pValue;
for(String s : data){
str+="\"PropertyName\":\"S"+id+"\",\"PropertyValue\":\""+s+"\"";
id++;
if(id != data.size()){
str+=",";
}
}
str+="}}\"}";
But it still did'nt work. The article does not specify how to feed the body in Java, maybe I did an error during the feeding of the REST call body ?
The String containing my data looks good
