|
42 | Ok, this section will not explain any freenet basics to you, just some |
|
|
43 | problems I found that you might want to avoid: |
|
|
44 | |
|
|
45 | =over 4 |
|
|
46 | |
|
|
47 | =item freenet URIs are _NOT_ URIs |
|
|
48 | |
|
|
49 | Whenever a "uri" is required by the protocol, freenet expects a kind of |
|
|
50 | URI prefixed with the "freenet:" scheme, e.g. "freenet:CHK...". However, |
|
|
51 | these are not URIs, as freeent fails to parse them correctly, that is, you |
|
|
52 | must unescape an escaped characters ("%2c" => ",") yourself. Maybe in the |
|
|
53 | future this library will do it for you, so watch out for this incompatible |
|
|
54 | change. |
|
|
55 | |
|
|
56 | =item Numbers are in HEX |
|
|
57 | |
|
|
58 | Virtually every number in the FCP protocol is in hex. Be sure to use |
|
|
59 | C<hex()> on all such numbers, as the module (currently) does nothing to |
|
|
60 | convert these for you. |
