coldfusion - HTTP/1.1 500 Complex object types cannot be converted to simple values -


i'm following tutorial ben nadel , receiving following error in browser network/xhr.

complex object types cannot converted simple values

i think problem in cfloop tag i'm not sure should modify resolve error.

<!---     content byte array (by converting binary,     can echo appropriate length use in     binary response stream. ---> <cfset binresponse = tobinary(tobase64( objrequest.filecontent )) />  <!--- echo response code. ---> <cfheader statuscode="#val( objrequest.statuscode )#" statustext="#listrest( objrequest.statuscode, ' ' )#" />  <!--- echo response legnth. ---> <cfheader name="content-length" value="#arraylen( binresponse )#" />  <!--- echo response heaers. ---> <cfloop item="strkey" collection="#objrequest.responseheader#">  <!--- check see if header simple value. --->     <cfif issimplevalue( objrequest.responseheader[ strkey ] )>          <!--- echo header value. --->         <cfheader name="#strkey#" value="#objrequest.responseheader[ strkey ]#" />     </cfif>  </cfloop>  <!---     echo content appropriate mime type. using     variable attribute, make sure content     stream reset , given response returned. ---> <cfcontent type="#objrequest.mimetype#" variable="#binresponse#" />

i commented out each line of code until found out problem line of code cfheader. turned out, don't need whole cfloop block of code. author of tutorial may have other use block of code do, works fine without it. many tried help.

<cfheader name="#strkey#" value="#objrequest.responseheader[ strkey ]#" />

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
