Can we receive a BLOB/binary as is from the request body?

Question

I am trying to receive a binary or BLOB as a REST server.
Is it possible to receive the request's body and parse the payload?
I understand using a property name it would be possible but would it be possible to get a handle of the incoming request body directly?

Hi Soura,There is a way to do this, and this is by adding the "postParameter" URL parameter to the request:https://domainme/Thingworx/Things/aaa/Services/bbb?postParameter=nameOfThingWorxServiceParameterYou must create a service named bbb, which must have a parameter named "nameOfThingWorxServiceParameter"If you do this, you can send the payload from the external system to ThingWorx without wrapping it in the normal JSON format ThingWorx expects ({"nameOfThingWorxServiceParameter":"payload"}.I use this exactly in the case when I want to send for example JSON payloads from external systems where I can not properly format the body (tested and still working in 9.1.2).Note that I did not try it with a parameter type BLOB, I think you should try it along this path.

@Soura Have you tried using ContentLoaderFunctions resource in thingworx? You can try using the loadbinary service for getting a binary result.

let params = {
proxyScheme: undefined /* STRING */,
headers: undefined /* JSON */,
ignoreSSLErrors: undefined /* BOOLEAN */,
useNTLM: undefined /* BOOLEAN */,
workstation: undefined /* STRING */,
useProxy: undefined /* BOOLEAN */,
proxyHost: undefined /* STRING */,
url: undefined /* STRING */,
timeout: undefined /* NUMBER */,
proxyPort: undefined /* INTEGER */,
password: undefined /* STRING */,
domain: undefined /* STRING */,
username: undefined /* STRING */
};

// result: BLOB
let result = Resources["ContentLoaderFunctions"].LoadBinary(params);
