The system variable #sendHeader is a variable that lets you add additional header lines to the post request sent by the send command. Each line must be finished with a $ to mark the end.
set #sendheader content-type: , #spc , blabla$line2: , #spc , blabla2$
  • If #sendheader doesn't contain any $ signs at all then no additional lines will be added to the header. Setting #sendheader to $$$ will obviously mess up the outgoing packet so that is not recommended.
  • First let's look at EUO default format for http requests:
; test1
send debugHTTPPost localhost /euo/action.php?getVar=getValue postVar=postValue
halt
  • Outgoing HTTP request:
POST /euo/action.php?getvar=getvalue HTTP/1.0 Host: localhost Content-Length: 17 postVar=postValue
  • Supposing you want your HTTP request to be identifiied as issued by EasyUO by adding the directive "User-Agent: EasyUO #cliVer" to the HTTP header:
; test2
set #sendHeader User-Agent: , #spc , EasyUO , #spc , #cliVer , $
send debugHTTPPost localhost /euo/action.php?getVar=getValue postVar=postValue
halt
  • Outgoing HTTP request:
POST /euo/action.php?getvar=getvalue HTTP/1.0 Host: localhost Content-Length: 17 user-agent: easyuo 4.0.0e postVar=postValue
  • If you need to specify more than one http directive, you may use the following syntax:
set #sendHeader User-Agent: , #spc , EasyUO , #spc , #cliVer , $ ,
+ Content-type: , #spc , application/x-www-form-urlencoded$
or
set #sendHeader User-Agent: , #spc , EasyUO , #spc , #cliVer , $
set #sendHeader #sendHeader , Content-type: , #spc , application/x-www-form-urlencoded$
  • In order to reset #sendHeader, try any of these:
set #sendHeader N/A
set #sendHeader invalid content


Note:
  • Two consecutive '$' will break the header structure and are likely to cause inpredictable results!
  • You cannot SET a value containing spaces to #sendHeader without 'escaping' them using the #spc constant.
  • The value of #sendHeader is converted to lowercase when added to the HTTP header.
  • It must be terminated by a single end-of-line symbol '$'. Without this symbol, #sendHeader value will be ignored and not added to the HTTP header.

Example


set #sendHeader Content-type: , #spc , application/x-www-form-urlencoded$

Result

  • Result variables hold values that are the direct by-product of actions taken by commands in a script. The exact details of what they contain is determined by the command and variable.
#menuButton Returns the name of the last clicked menu Button
#menuRes Returns the result of the last menu Get or menu GetNum command
#sendHeader Holds HTTP header information for the send command
#strRes Returns the result of the last str command
#property Returns the result of the last event Property command
#result Returns the result of the last return command
#opts Determines which EasyUO configuration options are active
#lpc Determines the number of lines that are executed per cycle
