Exaplanation of the Exec API for the wsCurl command.
The exec API enables you to specify a response to the query you are making. The response can be either JSON or HTML and the syntax is as follows:
var response = wsCurl.exec();
You can use the following syntax to check for the response:
println(wsCurl.error);
The exec API contains a number of response codes that may be returned. As definied by the cURL project, the currently available response codes are as follows:
Option | Integer Value | Definition |
---|---|---|
CURLE_OK | 0 | No errors occurred - the operation completed normally. |
CURLE_UNSUPPORTED_PROTOCOL | 1 |
The target URL is using a protocol used is not supported. Please check if the problem might be one of the following:
|
CURLE_FAILED_INIT | 2 | An early initialization failed and the operation did not complete. |
CURLE_URL_MALFORMAT | 3 | The target URL was not properly formatted. |
CURLE_NOT_BUILT_IN | 4 | A required feature, proptocol, or option was found to be missing from your version of libcurl. You will need to get a rebuilt libcurl in order for this to function. |

CURLE_COULDNT_RESOLVE_HOST | 6 | Could not resolve the given remote host. |
CURLE_COULDNT_CONNECT | 7 | Could not connect to either the host or the proxy. |
CURLE_FTP_WEIRD_SERVER_RESPONSE | 8 | Unexpected or improper response received from FTP server. This may mean that the given server is not a valid FTP server. |

CURLE_FTP_WEIRD_227_HOST | 14 | FTP servers typically return a 227-line in response to a PASV command. This code is returned if the libcurl fails to parse that response. |

|
CURLE_OPERATION_TIMEOUT | 28 | The specified timeout was reached and the operation was terminated. |
CURLE_FTP_PORT_FAILED | 30 | The FTP PORT command returned an error. This typically occurs if you specified an improper or incomplete address. |
