从 Go Daddy 的定价表中刮取更新定价

Question

https://www.godaddy.com/domains/popups/chart.aspx

我想为流行域的通用 TLD 争取续订价格。

我正在寻找源代码，但没有看到价格数字.... 这些变量在哪里找到？

Answer 1

价格在页面加载后动态生成...这是默认表格的价格链接

https://www.godaddy.com/domains/controls/jsoncontent/generalpricing.aspx?tab=general&widthreduction=160&hidelinks=true&TargetDivId=tabgj_new&regt=new&_=1380620289373

它返回一个可以使用json_decode()解析的json文件

要查看与页面交互时动态变化的内容，请在 chrome 中启动 developper tools，然后从顶部启动 Network 选项卡，从底部启动 XHR 选项卡...

在该选项卡中，您将看到网站和服务器之间的所有动态通信

编辑：

这是一个工作示例：

// includes Simple HTML DOM Parser
require_once "php/lib/simplehtmldom_1_5/simple_html_dom.php";

$url = "https://www.godaddy.com/domains/controls/jsoncontent/generalpricing.aspx?tab=general&widthreduction=160&hidelinks=true&TargetDivId=tabgj_new&regt=new&_=1380620289373";

// Download json file and converts it into a PHP variable
$jsonData = json_decode(file_get_contents($url));

// get html data from the json object
$htmlData = $jsonData->Html;


/*
 * Parse the HTML DOM using Simple HTML DOM Parser
 */

//Create a DOM object
$html = new simple_html_dom();
// Load HTML from a string
$html->load($htmlData);

// Print results
foreach($html->find("table tr") as $index => $row) {

    switch ($index) {

        case '0':   // Print table header
            foreach($row->find("th") as $col) {
                echo $col->plaintext;
                echo " | ";
            }
            echo "<br/>---<br/>";
            break;

        default:    // Print all rows
            foreach($row->find("td") as $col) {
                echo $col->plaintext;
                echo " | ";
            }
            echo "<br/>---<br/>";
            break;
    }
}
