我正在开发一个用户界面,“仪表板”,其上有一些div框,其中包含与当前登录用户相关的信息。他们的日历,待办事项列表以及从谷歌电子表格中动态提取的一些统计数据。
我在这里找到:
http://code.google.com/apis/spreadsheets/data/3.0/reference.html#CellFeed
可以使用这样的URL从工作表中请求特定单元格:
spreadsheets.google.com/feeds/cells/0AnhvV5acDaAvdDRvVmk1bi02WmJBeUtBak5xMmFTNEE/1/public/basic/R3C2
我简要介绍了Zend GData,但它似乎比我试图做的更复杂。
所以我写了两个php函数:(在hours.php中)
1.)根据参数行,列和表单执行生成的URL的file_get_contents()
2.)使用循环中的第一个来查找与给定名称相关联的列号。
所以基本上我使用jQuery做一个ajax请求,如下所示:
//开始js功能
function ajaxStats(fullname)
{
$.ajax({
url: "lib/dashboard.stats.php?name="+fullname,
cache: false,
success: function(html){
document.getElementById("stats").innerHTML = html;
}
});
}
//结束js功能
//开始文件hours.php
<?php
function getCol($name)
{
$r=1;
$c=2;
while(getCell($r,$c,1) != $name)
{ $c++; }
return $c;
}
function getCell($r, $c, $sheet)
{
$baseurl = "http://spreadsheets.google.com/feeds/cells/";
$spreadsheet = "0AnhvV5acDaAvdDRvVmk1bi02WmJBeUtBak5xMmFTNEE/";
$sheetID = $sheet . "/";
$vis = "public/";
$proj = "basic/";
$cell = "R".$r."C".$c;
$url = $baseurl . $spreadsheet . $sheetID . $vis . $proj . $cell . "";
$xml = file_get_contents($url);
//Sometimes the data is not xml formatted,
//so lets try to remove the url
$urlLen = strlen($url);
$xmlWOurl = substr($xml, $urlLen);
//then find the Z (in the datestamp, assuming its always there)
$posZ = strrpos($xmlWOurl, "Z");
//then substr from z2end
$data = substr($xmlWOurl, $posZ + 1);
//if the result has more than ten characters then something went wrong
//And most likely it is xml formatted
if(strlen($data) > 10)
{
//Asuming we have xml
$datapos = strrpos($xml,"<content type='text'>");
$datapos += 21;
$datawj = substr($xml, $datapos);
$endcont = strpos($datawj,"</content>");
return substr($datawj, 0,$endcont);
}
else
return $data;
}
?>
//结束hours.php
//开始dashboard.stats.php
<?php
session_start();
// This file is requested using ajax from the main dashboard because it takes so long to load,
// as to not slow down the usage of the rest of the page.
if (!empty($_GET['name']))
{
include "hours.php";
// GetCollumn of which C#R1 = users name
$col = getCol($_GET['name']);
// then get cell from each of the sheets for that user,
// assuming they are in the same column of each sheet
$s1 = getcell(3, $col, 1);
$s2 = getcell(3, $col, 2);
$s3 = getcell(3, $col, 3);
$s4 = getcell(3, $col, 4);
// Store my loot in the session varibles,
// so next time I want this, I don't need to fetch it
$_SESSION['fhrs'] = $s1;
$_SESSION['fdol'] = $s2;
$_SESSION['chrs'] = $s3;
$_SESSION['bhrs'] = $s4;
}
//print_r($_SESSION);
?>
<!-- and finally output the information formated for the widget-->
<strong>You have:</strong><br/>
<ul style="padding-left: 10px;">
<li> <strong><?php echo $_SESSION['fhrs']; ?></strong> fundraising hours<br/></li>
<li>earned $<strong><?php echo $_SESSION['fdol']; ?></strong> fundraising<br/></li>
<li> <strong><?php echo $_SESSION['chrs']; ?></strong> community service hours<br/></li>
<li> <strong><?php echo $_SESSION['bhrs']; ?></strong> build hours <br/></li>
</ul>
//结束dashboard.stats.php
我认为我失去4秒的地方是getCol()
[hours.php]中的while循环
如何改善这一点,减少加载时间?
我应该废弃这个,然后去Zend GData吗? 如果是while循环,我是否应该尝试在用户数据库中的电子表格中存储每个用户列号,该用户数据库还验证登录?
答案 0 :(得分:0)
我在while循环中没有正确的中断,即使在找到合适的人之后它仍然继续循环。
此外,请求需要一段时间才能转到Google电子表格。每个请求大约0.025秒。
我还与ZendGdata的用户进行了交谈,他们说请求速度不是很快。
