BE_HTTP_GET

BE_HTTP_GET


Does a http GET function and returns the results. This uses the curl library so output will be similar to that. This is used in conjunction with the BE_HTTP_SetCustomHeader function to set custom headers in advance and the BE_HTTP_ResponseCode and BE_HTTP_ResponseHeaders functions to get the result values after the GET is complete.

Parameters:

- url : the url to retrieve.

- filename : Required if you're saving the contents of the url ( i.e. text or a file ) into a container field. The container field uses the name supplied here for the name of the resulting file.

- username : The username if the url requires authentication.

- password : The password if the url requires authentication.

Version History:

- 1.2 :

- 3.3.0 : Renamed to BE_HTTP_GET from BE_GetURL

Notes:

- Check for errors using theBE_GetLastErrorfunction and use https://curl.haxx.se/libcurl/c/libcurl-errors.html for error details.

- Some useful header options : BE_CurlSetOption ( "CURLOPT_FOLLOWLOCATION" ; 1 ) will mean that it will follow a 301 redirect. BE_CurlSetOption ( "CURLOPT_HTTPAUTH" ; 1 ) forces Basic auth for some sites that won't work with the defaults. This function can also be used for FTP by using ftp:// urls. For example : BE_HTTP_GET ( "sftp://server/path/file.txt" ; "" ; ; ) and BE_CurlSetOption ( "CURLOPT_DIRLISTONLY" ; 1 ) BE_HTTP_GET ( "sftp://server/path/" ; "" ; ; ) to get a file listing at that path.
