从API获取/解析XML数据,这是在PHP中完成的


Getting/Parsing XML data from an API that is done in PHP

我正在我的网店上安装UPS送货计算器API,它可以正确地获取价格,这太棒了!不过,我找不到任何方法将这些价格转换成有用的格式。我想将它们用作php变量。

对于这个例子,我们将称之为mycartcart.php。

api由一个名为ups.hp.的文件执行

当客户将商品放入购物车并填写邮政编码时,他们会单击提交按钮,然后被引导到一个新的购物车页面,该页面运行ups.php脚本并在页面上显示数据(我稍后将删除该页面,以便它可以在后台运行)。如果这些文件中有任何一个是.xml文件,我可能会学习如何解析xml数据或在php中使用simpleXML命令。。。但他们似乎总是想要一个xml文件的位置,而我没有。有人知道如何将我的一个PHP文件中包含的XML数据用作PHP变量吗?

以下是ups.php中的一些代码:

    <?php
      $ch = curl_init("https://www.ups.com/ups.app/xml/Rate");
        curl_setopt($ch, CURLOPT_HEADER, 1);
        curl_setopt($ch,CURLOPT_POST,1);
        curl_setopt($ch,CURLOPT_TIMEOUT, 60);
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
        curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
        $result=curl_exec ($ch);
    echo ''. $result. '';
        $data = strstr($result, '<?');
        $xml_parser = xml_parser_create();
        xml_parse_into_struct($xml_parser, $data, $vals, $index);
        xml_parser_free($xml_parser);
        $params = array();
        $level = array();
        foreach ($vals as $xml_elem) {
         if ($xml_elem['type'] == 'open') {
        if (array_key_exists('attributes',$xml_elem)) {
             list($level[$xml_elem['level']],$extra) = array_values($xml_elem['attributes']);
        } else {
             $level[$xml_elem['level']] = $xml_elem['tag'];
        }
         }
         if ($xml_elem['type'] == 'complete') {
        $start_level = 1;
        $php_stmt = '$params';  
        while($start_level < $xml_elem['level']) {
             $php_stmt .= '[$level['.$start_level.']]';
             $start_level++;
        }
        $php_stmt .= '[$xml_elem[''tag'']] = $xml_elem[''value''];';
        eval($php_stmt);
         }
        }
        curl_close($ch);
        return $params['RATINGSERVICESELECTIONRESPONSE']['RATEDSHIPMENT']['TOTALCHARGES']['MONETARYVALUE'];
    }
?>

当我运行这个.php文件时,页面上的文本输出是什么样子的:

HTTP/1.1 100 Continue HTTP/1.1 200 OK Date: Wed, 25 Jul 2012 20:27:46 GMT

我想明白了。这是新代码。。。更短。更简单的方式。

我使用php命令进行explode();和普通数组语法,$newvariable=$existing_array[key#];

谢谢大家的评论!

    <?php
    $ch = curl_init("https://www.ups.com/ups.app/xml/Rate");
    curl_setopt($ch, CURLOPT_HEADER, 0);

    curl_setopt($ch,CURLOPT_TIMEOUT, 60);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
    $result=curl_exec ($ch);                    
    $upsout = (explode('USD', $result, 15));
    $handling = $upsout[3]; 
    echo "Shipping cost is $";
    echo $handling; 
    curl_close($ch);
}
