GET_LAST_ERROR(Error)

Parameters

Parameter	Type	Direction	Description
Error	String	OUT	Returned error string from CURL

Return Values

Values Returned in $status
Value	Meaning
`0`	Success
`-12`	An internal error occurred

Use

Can be used after the SEND operation.

Description

The GET_LAST_ERROR operation allows you to troubleshoot the SEND operation in case it returns the error -12 ("Internal error"). Otherwise, the calling program does not know what the -12 means.

GET_LAST_ERROR returns the last CURL error caused by the previous SEND operation. It contains the actual error information. For a full list of CURL error codes, see libcurl error codes.

Errors are returned with the syntax:

CurlErrorCode = CurlErrorText

For example, if UHTTP.SEND returns the error -12 because the required SSL certificates are not available, calling GET_LAST_ERROR returns the following:

77 = Problem with the SSL CA cert (path? access rights?)

You can split the returned error string and format it as required. For example:

activate "UHTTP".GET_LAST_ERROR(Error)
errorCode = $idpart(Error)
errorText = $valuepart(Error)
message/error $concat("UHTTP.SEND returned the curl error ", errorCode, " - ", errorText)

If no CURL error is set, GET_LAST_ERROR returns an empty string.
