It ! 59: will not attempt to decode the scheme, the port number or the full URL. ! 60: ! 61: The query component will also get plus-to-space conversion as a bonus when ! 62: this bit is set. ! 63: ! 64: Note that this URL decoding is charset unaware and you will get a zero ! 65: terminated string back with data that could be intended for a particular ! 66: encoding. ! 67: ! 68: If there's any byte values lower than 32 in the decoded string, the get ! 69: operation will return an error instead. ! 70: .SH PARTS ! 71: .IP CURLUPART_URL ! 72: When asked to return the full URL, \fIcurl_url_get(3)\fP will return a ! 73: normalized and possibly cleaned up version of what was previously parsed. ! 74: .IP CURLUPART_SCHEME ! 75: Scheme cannot be URL decoded on get. ! 76: .IP CURLUPART_USER ! 77: .IP CURLUPART_PASSWORD ! 78: .IP CURLUPART_OPTIONS ! 79: .IP CURLUPART_HOST ! 80: The host name. If it is an IPv6 numeric address, the zoneid will not be part ! 81: of it but is provided separately in \fICURLUPART_ZONEID\fP. IPv6 numerical ! 82: addresses are returned within brackets ([]). ! 83: .IP CURLUPART_ZONEID ! 84: If the host name is a numeric IPv6 address, this field might also be set. ! 85: .IP CURLUPART_PORT ! 86: Port cannot be URL decoded on get. ! 87: .IP CURLUPART_PATH ! 88: .IP CURLUPART_QUERY ! 89: The query part will also get pluses converted to space when asked to URL ! 90: decode on get with the CURLU_URLDECODE bit. ! 91: .IP CURLUPART_FRAGMENT ! 92: .SH RETURN VALUE ! 93: Returns a CURLUcode error value, which is CURLUE_OK (0) if everything went ! 94: fine. ! 95: ! 96: If this function returns an error, no URL part is returned. ! 97: .SH EXAMPLE ! 98: .nf ! 99: CURLUcode rc; ! 100: CURLU *url = curl_url(); ! 101: rc = curl_url_set(url, CURLUPART_URL, "https://example.com", 0); ! 102: if(!rc) { ! 103: char *scheme; ! 104: rc = curl_url_get(url, CURLUPART_SCHEME, &scheme, 0); ! 105: if(!rc) { ! 106: printf("the scheme is %s\\n", scheme); ! 107: curl_free(scheme); ! 108: } ! 109: curl_url_cleanup(url); ! 110: } ! 111: .fi ! 112: .SH AVAILABILITY ! 113: Added in curl 7.62.0. CURLUPART_ZONEID was added in 7.65.0. ! 114: .SH "SEE ALSO" ! 115: .BR curl_url_cleanup "(3), " curl_url "(3), " curl_url_set "(3), " ! 116: .BR curl_url_dup "(3), "
