Springcloud data flow stream with http-request post

I'm trying to deploy a springcloud data flow stream like this:

time | http-request --http-method-expression='POST' --url-expression='http://mydomain.fake/myservice?myparams=myvalues'  | log

The stream deploy without errors, but when I check the http-request log I can see a exception. Obviously, the stream not works

Property or field 'POST' cannot be found on object of type 'org.springframework.messaging.support.GenericMessage'

I checked the HttpRequestFunctionProperties class from github, but I didn't get any clue about my fault.

Any help please?

Update 1:

I get it. It works with --http-method-expression=new String('POST') BUT only when the stream is updated . I cant deploy the stream directly with this param ...

Thanks !!!

Solution

  • The error indicates that the SpEL parser is interpreting POST as a field on the Message (the default evaluation context). The expression 'POST' is not being parsed correctly as a literal string. This is most likely due to some escaping problem. Try what Gary suggests.
