cURL documentation

In the component diagram, these options can be set on the URL adapter alias. Use tagged value options in order to set cURL options.
If you want to specify multiple cURL options, list them separated by ',' (comma) or ' ' (blank). If an option allows for multiple values, you can concatenate them by using the '|' (pipe) operator.

Examples:

CURLOPT_CONNECTTIMEOUT=60 (see note below for a hint on this option)
CURLOPT_CONNECTTIMEOUT=60, E2E_FORBID_REUSE=true
CURLOPT_CONNECTTIMEOUT=60 E2E_FORBID_REUSE=true
CURLOPT_HTTPAUTH=CURLAUTH_NTLM|CURLAUTH_NEGOTIATE, E2E_FORBID_REUSE=true

Alternatively it is possible to set the cURL options dynamically in an activity diagram. For that purpose, input an object of type array with name options directly into the URL adapter. The array element must be of class Option which is located in package Base Components/Add Ons/URL. Set the cURL option you want to set to attribute name and the value to attribute value.

Example:

Example File (Builder project Add-ons/URL):

<bridgeDocPath>\\Add-ons\URL\uml\urlCurl.xml

E2E cURL Options

Option	Data Type	Remarks
`E2E_FORBID_REUSE`	Boolean	If `E2E_FORBID_REUSE` is "true" for a SOAP adapter, then all curl connections are closed after the request. This also affects URL adapter options, if there are any.

Native cURL Options

Internally, the URL adapter uses cURL. The following options - listed in alphabetical order - are currently supported (see the cURL documentation for more details).

Legend:	Option is recognized and forwarded to cURL Option is recognized and forwarded to cURL, but may overwrite built-in URL adapter functionality Option is not supported and not forwarded to cURL

All cURL data types can be set by using Bridge Strings:

cURL Data Type	Bridge Type	Comment
Array(String)	Array of Strings	You must use a cast() to use this type, because the URL option value is of type String.
Blob	n/a	Is not supported.
Boolean	String	You can use `false` or `0` for false and `true` or `1` for true.
Callback	n/a	Is not supported.
Constant	String	Use the defined strings from cURL. For example, for the option `CURLOPT_FTP_FILEMETHOD` you can use `CURLFTPMETHOD_MULTICWD`, `CURLFTPMETHOD_NOCWD` or `CURLFTPMETHOD_SINGLECWD`. The xUML Runtime will convert the strings to numbers.
FileHandle	n/a	Is not supported.
Integer	String	String will be converted to a number.
String	String
