|
|---|
| 88 |
|
|---|
| 89 |
|
|---|
| 90 | The QFtp class provides an implementation of the FTP protocol.
|
|---|
| 91 |
|
|---|
| 92 | <p>
|
|---|
| 93 |
|
|---|
| 94 | <p> This class provides two different interfaces: one is the
|
|---|
| 95 | <a href="qnetworkprotocol.html">QNetworkProtocol</a> interface that allows you to use FTP through the
|
|---|
| 96 | <a href="qurloperator.html">QUrlOperator</a> abstraction. The other is a direct interface to FTP
|
|---|
| 97 | that gives you lower-level access to the FTP protocol for finer
|
|---|
| 98 | control. Using the direct interface you can also execute arbitrary
|
|---|
| 99 | FTP commands.
|
|---|
| 100 | <p> Don't mix the two interfaces, since the behavior is not
|
|---|
| 101 | well-defined.
|
|---|
| 102 | <p> If you want to use QFtp with the QNetworkProtocol interface, you
|
|---|
| 103 | do not use it directly, but rather through a QUrlOperator, for
|
|---|
| 104 | example:
|
|---|
| 105 | <p> <pre>
|
|---|
| 106 | <a href="qurloperator.html">QUrlOperator</a> op( "ftp://ftp.trolltech.com" );
|
|---|
| 107 | op.<a href="qurloperator.html#listChildren">listChildren</a>(); // Asks the server to provide a directory listing
|
|---|
| 108 | </pre>
|
|---|
| 109 |
|
|---|
| 110 | <p> This code will only work if the QFtp class is registered; to
|
|---|
| 111 | register the class, you must call <a href="qurloperator.html#qInitNetworkProtocols">qInitNetworkProtocols</a>() before
|
|---|
| 112 | using a QUrlOperator with QFtp.
|
|---|
| 113 | <p> The rest of this descrption describes the direct interface to FTP.
|
|---|
| 114 | <p> The class works asynchronously, so there are no blocking
|
|---|
| 115 | functions. If an operation cannot be executed immediately, the
|
|---|
| 116 | function will still return straight away and the operation will be
|
|---|
| 117 | scheduled for later execution. The results of scheduled operations
|
|---|
| 118 | are reported via signals. This approach depends on the event loop
|
|---|
| 119 | being in operation.
|
|---|
| 120 | <p> The operations that can be scheduled (they are called "commands"
|
|---|
| 121 | in the rest of the documentation) are the following:
|
|---|
| 122 | <a href="#connectToHost">connectToHost</a>(), <a href="#login">login</a>(), <a href="#close">close</a>(), <a href="#list">list</a>(), <a href="#cd">cd</a>(), <a href="#get">get</a>(), <a href="#put">put</a>(),
|
|---|
| 123 | <a href="#remove">remove</a>(), <a href="#mkdir">mkdir</a>(), <a href="#rmdir">rmdir</a>(), <a href="#rename">rename</a>() and <a href="#rawCommand">rawCommand</a>().
|
|---|
| 124 | <p> All of these commands return a unique identifier that allows you
|
|---|
| 125 | to keep track of the command that is currently being executed.
|
|---|
| 126 | When the execution of a command starts, the <a href="#commandStarted">commandStarted</a>()
|
|---|
| 127 | signal with the command's identifier is emitted. When the command
|
|---|
| 128 | is finished, the <a href="#commandFinished">commandFinished</a>() signal is emitted with the
|
|---|
| 129 | command's identifier and a bool that indicates whether the command
|
|---|
| 130 | finished with an error.
|
|---|
| 131 | <p> In some cases, you might want to execute a sequence of commands,
|
|---|
| 132 | e.g. if you want to connect and login to a FTP server. This is
|
|---|
| 133 | simply achieved:
|
|---|
| 134 | <p> <pre>
|
|---|
| 135 | QFtp *ftp = new QFtp( this ); // this is an optional QObject parent
|
|---|
| 136 | ftp-><a href="#connectToHost">connectToHost</a>( "ftp.trolltech.com" );
|
|---|
| 137 | ftp-><a href="#login">login</a>();
|
|---|
| 138 | </pre>
|
|---|
| 139 |
|
|---|
| 140 | <p> In this case two FTP commands have been scheduled. When the last
|
|---|
| 141 | scheduled command has finished, a <a href="#done">done</a>() signal is emitted with
|
|---|
| 142 | a bool argument that tells you whether the sequence finished with
|
|---|
| 143 | an error.
|
|---|
| 144 | <p> If an error occurs during the execution of one of the commands in
|
|---|
| 145 | a sequence of commands, all the pending commands (i.e. scheduled,
|
|---|
| 146 | but not yet executed commands) are cleared and no signals are
|
|---|
| 147 | emitted for them.
|
|---|
| 148 | <p> Some commands, e.g. <a href="#list">list</a>(), emit additional signals to report
|
|---|
| 149 | their results.
|
|---|
| 150 | <p> Example: If you want to download the INSTALL file from Trolltech's
|
|---|
| 151 | FTP server, you would write this:
|
|---|
| 152 | <p> <pre>
|
|---|
| 153 | ftp->connectToHost( "ftp.trolltech.com" ); // id == 1
|
|---|
| 154 | ftp->login(); // id == 2
|
|---|
| 155 | ftp->cd( "qt" ); // id == 3
|
|---|
| 156 | ftp->get( "INSTALL" ); // id == 4
|
|---|
| 157 | ftp->close(); // id == 5
|
|---|
| 158 | </pre>
|
|---|
| 159 |
|
|---|
| 160 | <p> For this example the following sequence of signals is emitted
|
|---|
| 161 | (with small variations, depending on network traffic, etc.):
|
|---|
| 162 | <p> <pre>
|
|---|
| 163 | <a href="qnetworkprotocol.html#start">start</a>( 1 )
|
|---|
| 164 | <a href="#stateChanged">stateChanged</a>( <a href="#State-enum">HostLookup</a> )
|
|---|
| 165 | <a href="#stateChanged">stateChanged</a>( <a href="#State-enum">Connecting</a> )
|
|---|
| 166 | <a href="#stateChanged">stateChanged</a>( <a href="#State-enum">Connected</a> )
|
|---|
| 167 | <a href="qnetworkprotocol.html#finished">finished</a>( 1, FALSE )
|
|---|
| 168 |
|
|---|
| 169 | <a href="qnetworkprotocol.html#start">start</a>( 2 )
|
|---|
| 170 | <a href="#stateChanged">stateChanged</a>( <a href="#State-enum">LoggedIn</a> )
|
|---|
| 171 | <a href="qnetworkprotocol.html#finished">finished</a>( 2, FALSE )
|
|---|
| 172 |
|
|---|
| 173 | <a href="qnetworkprotocol.html#start">start</a>( 3 )
|
|---|
| 174 | <a href="qnetworkprotocol.html#finished">finished</a>( 3, FALSE )
|
|---|
| 175 |
|
|---|
| 176 | <a href="qnetworkprotocol.html#start">start</a>( 4 )
|
|---|
| 177 | <a href="#dataTransferProgress">dataTransferProgress</a>( 0, 3798 )
|
|---|
| 178 | <a href="#dataTransferProgress">dataTransferProgress</a>( 2896, 3798 )
|
|---|
| 179 | <a href="#readyRead">readyRead</a>()
|
|---|
| 180 | <a href="#dataTransferProgress">dataTransferProgress</a>( 3798, 3798 )
|
|---|
| 181 | <a href="#readyRead">readyRead</a>()
|
|---|
| 182 | <a href="qnetworkprotocol.html#finished">finished</a>( 4, FALSE )
|
|---|
| 183 |
|
|---|
| 184 | <a href="qnetworkprotocol.html#start">start</a>( 5 )
|
|---|
| 185 | <a href="#stateChanged">stateChanged</a>( <a href="#State-enum">Closing</a> )
|
|---|
| 186 | <a href="#stateChanged">stateChanged</a>( <a href="#State-enum">Unconnected</a> )
|
|---|
| 187 | <a href="qnetworkprotocol.html#finished">finished</a>( 5, FALSE )
|
|---|
| 188 |
|
|---|
| 189 | <a href="#done">done</a>( FALSE )
|
|---|
| 190 | </pre>
|
|---|
| 191 |
|
|---|
| 192 | <p> The <a href="#dataTransferProgress">dataTransferProgress</a>() signal in the above example is useful
|
|---|
| 193 | if you want to show a <a href="qprogressbar.html">progressbar</a> to
|
|---|
| 194 | inform the user about the progress of the download. The
|
|---|
| 195 | <a href="#readyRead">readyRead</a>() signal tells you that there is data ready to be read.
|
|---|
| 196 | The amount of data can be queried then with the <a href="#bytesAvailable">bytesAvailable</a>()
|
|---|
| 197 | function and it can be read with the <a href="#readBlock">readBlock</a>() or <a href="#readAll">readAll</a>()
|
|---|
| 198 | function.
|
|---|
| 199 | <p> If the login fails for the above example, the signals would look
|
|---|
| 200 | like this:
|
|---|
| 201 | <p> <pre>
|
|---|
| 202 | <a href="qnetworkprotocol.html#start">start</a>( 1 )
|
|---|
| 203 | <a href="#stateChanged">stateChanged</a>( <a href="#State-enum">HostLookup</a> )
|
|---|
| 204 | <a href="#stateChanged">stateChanged</a>( <a href="#State-enum">Connecting</a> )
|
|---|
| 205 | <a href="#stateChanged">stateChanged</a>( <a href="#State-enum">Connected</a> )
|
|---|
| 206 | <a href="qnetworkprotocol.html#finished">finished</a>( 1, FALSE )
|
|---|
| 207 |
|
|---|
| 208 | <a href="qnetworkprotocol.html#start">start</a>( 2 )
|
|---|
| 209 | <a href="qnetworkprotocol.html#finished">finished</a>( 2, TRUE )
|
|---|
| 210 |
|
|---|
| 211 | <a href="#done">done</a>( TRUE )
|
|---|
| 212 | </pre>
|
|---|
| 213 |
|
|---|
| 214 | <p> You can then get details about the error with the <a href="#error">error</a>() and
|
|---|
| 215 | <a href="#errorString">errorString</a>() functions.
|
|---|
| 216 | <p> The functions <a href="#currentId">currentId</a>() and <a href="#currentCommand">currentCommand</a>() provide more
|
|---|
| 217 | information about the currently executing command.
|
|---|
| 218 | <p> The functions <a href="#hasPendingCommands">hasPendingCommands</a>() and <a href="#clearPendingCommands">clearPendingCommands</a>()
|
|---|
| 219 | allow you to query and clear the list of pending commands.
|
|---|
| 220 | <p> The safest and easiest way to use the FTP protocol is to use
|
|---|
| 221 | <a href="qurloperator.html">QUrlOperator</a>() or the FTP commands described above. If you are an
|
|---|
| 222 | experienced network programmer and want to have complete control
|
|---|
| 223 | you can use <a href="#rawCommand">rawCommand</a>() to execute arbitrary FTP commands.
|
|---|

|

| 295 | <p> If there is an unfinished command (i.e. a command for which the

|---|
| 296 | <a href="#commandStarted">commandStarted</a>() signal has been emitted, but for which the
|
|---|
| 297 | <a href="#commandFinished">commandFinished</a>() signal has not been emitted), this function
|
|---|
| 298 | sends an <tt>ABORT</tt> command to the server. When the server replies
|
|---|
| 299 | that the command is aborted, the commandFinished() signal with the
|
|---|
| 300 | <tt>error</tt> argument set to <tt>TRUE</tt> is emitted for the command. Due
|
|---|
| 301 | to timing issues, it is possible that the command had already
|
|---|
| 302 | finished before the abort request reached the server, in which
|
|---|
| 303 | case, the commandFinished() signal is emitted with the <tt>error</tt>
|

| 304 | argument set to <tt>FALSE</tt>.
|
|---|
| 305 | <p> For all other commands that are affected by the <a href="#abort">abort</a>(), no

| 471 | when the readyRead() signal is emitted, it is still available
|
|---|
| 472 | until the next command is started.
|
|---|
| 473 | <p> For example, if you want to present the data to the user as soon

|
|---|
| 549 | Reads the data from the IO device <em>dev</em>, and writes it to the
