| 6547 | 851 @deftypefnx {Loadable Function} {[@dots{}] =} urlread (@var{url}, @var{method}, @var{param})\n\ |
| 9880 | 852 Download a remote file specified by its @var{url} and return its content\n\ |
| 6043 | 853 in string @var{s}. For example,\n\ |
| 854 \n\ | |
| 855 @example\n\ | |
| 6588 | 856 s = urlread (\"ftp://ftp.octave.org/pub/octave/README\");\n\ |
| 6043 | 857 @end example\n\ |
| 858 \n\ | |
| 859 The variable @var{success} is 1 if the download was successful,\n\ | |
| 860 otherwise it is 0 in which case @var{message} contains an error\n\ | |
| 861 message. If no output argument is specified and if an error occurs,\n\ | |
| 6588 | 862 then the error is signaled through Octave's error handling mechanism.\n\ |
| 6043 | 863 \n\ |
| 864 This function uses libcurl. Curl supports, among others, the HTTP,\n\ | |
| 865 FTP and FILE protocols. Username and password may be specified in the\n\ | |
| 866 URL. For example,\n\ | |
| 867 \n\ | |
| 868 @example\n\ | |
| 7031 | 869 s = urlread (\"http://user:password@@example.com/file.txt\");\n\ |
| 6043 | 870 @end example\n\ |
| 871 \n\ | |
| 872 GET and POST requests can be specified by @var{method} and @var{param}.\n\ | |
| 6588 | 873 The parameter @var{method} is either @samp{get} or @samp{post}\n\ |
| 874 and @var{param} is a cell array of parameter and value pairs.\n\ | |
| 6650 | 875 For example,\n\ |
| 6043 | 876 \n\ |
