|
---|
28 | <h3>Description</h3>
|
---|
29 | <p>Gets a file from a URL. When the verbose option is "on", this task
|
---|
30 | displays a '.' for every 100 Kb retrieved. Any URL schema supported by
|
---|
31 | the runtime is valid here, including http:, ftp: and jar:;
|
---|
32 | https: is only valid if the appropriate support is added to the pre-1.4 Java
|
---|
33 | runtimes.
|
---|
34 |
|
---|
35 | </p>
|
---|
36 | The <i>usetimestamp</i> option enables you to control downloads so that the remote file is
|
---|
37 | only fetched if newer than the local copy. If there is no local copy, the download always takes
|
---|
38 | place. When a file is downloaded, the timestamp of the downloaded file is set to the remote timestamp,
|
---|
39 | if the JVM is Java1.2 or later.
|
---|
40 | NB: This timestamp facility only works on downloads using the HTTP protocol.
|
---|
41 | <p>
|
---|
42 | A username and password can be specified, in which case basic 'slightly encoded
|
---|
43 | plain text' authentication is used. This is only secure over an HTTPS link.
|
---|
44 | </p>
|
---|
45 | <p>
|
---|
46 | <b>Proxies</b>. Since Ant1.7, Ant running on Java1.5 or later defaults to
|
---|
47 | <a href="../proxy.html">using
|
---|
48 | the proxy settings of the operating system</a>. There is also the
|
---|
49 | <a href="../OptionalTasks/setproxy.html"><setproxy></a> task for
|
---|
50 | earlier Java versions. With proxies turned on, <code><get></code> requests against
|
---|
51 | localhost may not work as expected, if the request is relayed to the proxy.
|
---|
52 | The <code>-noproxy</code> option can be used to turn this feature off.
|
---|

|

101 | <pre> <get src="http://ant.apache.org/" dest="help/index.html"/></pre>
|
---|
102 | <p>Gets the index page of http://ant.apache.org/, and stores it in the file <code>help/index.html</code>.</p>
|
---|
103 |
|
---|
104 | <pre> <get src="http://www.apache.org/dist/ant/KEYS"
|
---|
105 | dest="KEYS"
|
---|
106 | verbose="true"
|
---|
107 | usetimestamp="true"/></pre>
|
---|
108 | <p>
|
---|
109 | Gets the PGP keys of Ant's (current and past) release managers, if the local copy
|
---|
110 | is missing or out of date. Uses the verbose option
|
---|
111 | for progress information.
|
---|
112 | </p>
|
---|
113 |
|
---|
114 | <pre> <get src="https://insecure-bank.org/statement/user=1214"
|
---|
115 | dest="statement.html"
|
---|
116 | username="1214";
|
---|
117 | password="secret"/></pre>
|
---|
118 | <p>
|
---|
119 | Fetches some file from a server with access control. Because https is being used the
|
---|
120 | fact that basic auth sends passwords in plaintext is moot.
