Use Outside the Cloud

When not being called from within a DMP Component, the dmp module does not give you additional functionality over that supplied by mmhttp. However, some users may find it useful to use the dmp module outside the cloud when writing libraries to work inside and outside the cloud.

You can use dmpiniturl to initialize a DMP resource with a set of user-supplied authorization headers, and then make HTTP requests to that resource using dmphttp functions. For example, if you have a local webservice with the URL http://localhost:8860/ that requires a cookie for authorization, you can call it as follows:

declarations
  myurl: dmpresource
  headers: dynamic array(set of string) of text
end-declarations
headers("Cookie") := "SESSIONID=8364825249"
dmpiniturl(myurl, "http://localhost:8860/", headers)
if myurl.status<>DMP_OK then
  writeln('ERROR: ',myurl.lasterror)
  exit(1)
end-if

httpStatusCode := dmphttpget(myurl,'/rest/runtime/status','result.json')
if httpStatusCode<>200 then
  writeln('Error returned from webservice request: ',httpStatusCode)
  exit(1)
end-if
