Django开发之html交互

html中用户输入信息，由Django的view.py处理，大致用到了以下几类格式：

1. 文本框

<input type="text" name="vid" size="10" height="20">

或由bootcss修饰的

<div class="col-sm-2" >

<input type="text" class="form-control" id="username" name="username" placeholder="Username">

</div>

这种相对比较简单

version_num=request.GET.get("vid")

2. 文本框

<td width="30%" align="center" valign="top">粘帖需要发布的其他所有UI</td>

<td><textarea rows="10" cols="40" id="newui" name="newui" ></textarea></td>

这种要这样接收，返回结果是一个列表，相对比较好处理

    otherNewUI=request.GET.get("newui").encode('utf8').split("\r\n")

    '''return result like this:

    [u'GameStub.swf.new', u'giftui.swf', u'zhuui2.swf']

    '''

3. 多选按钮，返回值也是一个列表

        <td width="30%" align="center" valign="top" >选择ini.xml中需要发布的ui</td>

        <td>

            <input type="checkbox" name="ui_list" value="GameStub.swf.new" />GameStub.swf.new<br />

            <input type="checkbox" name="ui_list" value="giftui.swf" />giftui.swf<br />

            <input type="checkbox" name="ui_list" value="zhuui2.swf" />zhuui2.swf<br />

            <input type="checkbox" name="ui_list" value="vipui.swf" />vipui.swf<br />

            <input type="checkbox" name="ui_list" value="giftboxui.swf" />giftboxui.swf<br />

            <input type="checkbox" name="ui_list" value="baseui.swf" />baseui.swf<br />

            <input type="checkbox" name="ui_list" value="xinshouui.swf" />xinshouui.swf<br />

            <input type="checkbox" name="ui_list" value="buildingui.swf" />buildingui.swf<br />

            <input type="checkbox" name="ui_list" value="jiuguanui.swf" />jiuguanui.swf<br />

        </td>

    newUiList=request.GET.getlist("ui_list")

    '''return result like this:

    [u'GameStub.swf.new', u'giftui.swf', u'zhuui2.swf']

    '''

4. cookie用法

写cookie，并执行跳转

    response=render_to_response('verIntegration/uiPrepare.html',{"current_version":current_version,"gameName":gameName})

    response.set_cookie("game",game,600)

    return response

读cookie，判断cookie是否失效

    if "game" in request.COOKIES:

        game=request.COOKIES["game"]

        gameName=CONFIG[game]['name']

        print "cookie still in "

    else:

        gameName="未知"

        print "cookie has gone"

        return render_to_response('verIntegration/uiPrepare.html',{"gameName":gameName})

5. pexpect方法执行交互式操作

def pullFile(gameConfig,remoteFileName,localFileName):

    #使用目录均为相对路径，绝对路径从字典中读取

    cmd="scp -P %s %s@%s:%s/%s %s/%s" % (gameConfig['port'],gameConfig['user'],gameConfig['ip'],gameConfig['remote_dir'],remoteFileName,gameConfig['local_dir'],localFileName)

    expect1="password: "

    child = pexpect.spawn(cmd)

    child.expect(expect1)

    child.sendline(gameConfig['password'])

    child.read()

    return None

6. pexpect远程执行脚本，这个可以参考pexpect的example中的hive.py

def remoteRun(gameConfig,cmd):

    srv_ip=gameConfig['ip']

    srv_port=gameConfig['port']

    srv_username=gameConfig['user']

    srv_password=gameConfig['password']

    try:

        ssh=paramiko.SSHClient()

        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

        ssh.connect(srv_ip,srv_port,srv_username,srv_password,timeout=5)

        stdin, stdout, stderr = ssh.exec_command(cmd)

        outlist=[]

        for out in stdout:

            outlist.append(out.strip('\n'))

    except Exception,e:

        print "Error"

        print e

    return None
