TSReturnCode TSUrlCreate(TSMBuffer bufp, TSMLoc *locp)¶

TSParseResult TSUrlParse(TSMBuffer bufp, TSMLoc offset, const char **start, const char *end)¶
解説¶
The URL data structure is a parsed version of a standard internet URL. The Traffic Server URL API provides access to URL data stored in marshal buffers. The URL functions can create, copy, retrieve or delete entire URLs, and retrieve or modify parts of URLs, such as their host, port or scheme information.
TSUrlCreate() creates a new URL within the marshal buffer
bufp. Release the resulting handle with a call to
TSHandleMLocRelease().
TSUrlClone() copies the contents of the URL at location src_url
within the marshal buffer src_bufp to a location within the marshal
buffer dest_bufp. Release the returned handle with a call to
TSHandleMLocRelease().
TSUrlCopy() copies the contents of the URL at location src_url
within the marshal buffer src_bufp to the location dest_url
within the marshal buffer dest_bufp. TSUrlCopy() works correctly even if
src_bufp and dest_bufp point to different marshal buffers. It
is important for the destination URL (its marshal buffer and TSMLoc)
to have been created before copying into it.
TSUrlParse() parses a URL. The start pointer is both an input
and an output parameter and marks the start of the URL to be parsed. After a
successful parse, the start pointer equals the end
pointer. The end pointer must be one byte after the last character you
want to parse. The URL parsing routine assumes that everything between
start and end is part of the URL. It is up to higher level
parsing routines, such as TSHttpHdrParseReq(), to determine the actual
end of the URL.
Return Values¶
The TSUrlParse() function returns a TSParseResult, where
TS_PARSE_ERROR indicates an error. Success is indicated by one of
TS_PARSE_DONE or TS_PARSE_CONT. The other APIs all return
a TSReturnCode, indicating success (TS_SUCCESS) or failure
(TS_ERROR) of the operation.
