ObjectMethod *registerExternalHTTPHandler (\&fn)

 
Changed:
<
<		Get whatever is at the other end of a URL (using an HTTP GET request). Will only work for encrypted protocols such as https if the LWP CPAN module is installed.
>
>		See TWikiFuncDotPm#RegisterExternalHTTPHandler
 
Deleted:
<
<		Note that the $url may have an optional user and password, as specified by the relevant RFC. Any proxy set in configure is honored.
 
Deleted:
<
<		Optional headers may be supplied of form 'name1', 'value1', 'name2', 'value2'. Do not add a User-Agent header, it will be added.
 
Changed:
<
<		The $response is an object that is known to implement the following subset of the methods of LWP::Response. It may in fact be an LWP::Response object, but it may also not be if LWP is not available, so callers may only assume the following subset of methods is available:
code()
message()
header($field)
content()
is_error()
is_redirect()

>

ObjectMethod *getExternalResource ($url,\@headers,\%params) -> $response

 
Changed:
<
<		Note that if LWP is not available, this function:
  1. can only really be trusted for HTTP/1.0 urls. If HTTP/1.1 or another protocol is required, you are strongly recommended to require LWP.
  2. Will not parse multipart content

>		See TWikiFuncDotPm#GetExternalResource
 
Deleted:
<
<		In the event of the server returning an error, then is_error() will return true, code() will return a valid HTTP status code as specified in RFC 2616 and RFC 2518, and message() will return the message that was received from the server. In the event of a client-side error (e.g. an unparseable URL) then is_error() will return true and message() will return an explanatory message. code() will return 400 (BAD REQUEST).
 
Deleted:
<
<		Note: Callers can easily check the availability of other HTTP::Response methods as follows:
 
Changed:
<
<
my $response = TWiki::Func::getExternalResource($url);
if (!$response->is_error() && $response->isa('HTTP::Response')) {
    $text = $response->content();
    # ... other methods of HTTP::Response may be called
} else {
    # ... only the methods listed above may be called

ObjectMethod setMailHandler (\&fn)

 
  • \&fn - reference to a function($) (see _sendEmailBySendmail for proto)
