Setting the header values in webRequest?

Permanently deleted user

So can anyone tell me how I set/amend the header name/value pairs in the WebRequest activity?

 

Basically I have a workflow which generates a JSON string; this utlimately needs to be passed to an external REST web service (POST method) which accepts JSON in the message payload (Content-Type:application/json).

 

So in my workflow I have:

 

1) Converted my JSON string to byte data with (getBytesFromText with UTF8 encoding) - variable named 'outputRequestByte')

 

2) In my webRequest activity I have then set the then set 'Raw Data' to this 'outputRequestByte' variable, assigned the URI endpoint.; and explicitly set the method to POST

 

However in the webRequest  I think I also need to explcitly set the Content-Type header name to a value of "application/json", but whilst I have no problem setting the webRequest Header parameter to a variable of System.Net.WebHeaderCollection I am struggling to assign a name/value pair of "Content-Type:application/json" to this collection variable.

 

Can anyone help? A similar thread (in whihc I've also posted my problem) called setting Content-Type of WebRequest states this is entirely possible - but unfortiunately the referenced workflows in this thread are not accessible. Sure I'm doing something silly here......

 

Thanks

  Hi Phil,

   

  You need to create a variable say "webHeaders" of type "System.Net.WebHeaderCollection", then use an Invoke Method as follows:

   

       TargetObject = webHeaders

   

       MethodName = Add

   

       Parameters: Type = String

   

  Value = "new WebHeaders("Accept: application/json; odata=verbose") Now, pass webHeader to the WebRequest activity as headers.

   

  Kindly let me know if you need any more help.

   

  Regards,

  Trying to do this but get the error: "

   

  The Content-Type header cannot be changed from its default value for this request."

  Hi Darko,

   

  If you are still getting this error, can you please post a sample request and obscure the data as required?
