Question

我一直在尝试为网站构建USPS费率计算器，但不幸的是，来自USPS的测试网址似乎不起作用。在任何情况下，我的代码目前都不返回任何内容，甚至没有关于url的错误消息......

你会看看我做的是否正确吗？我在PHP上的XML上有点迷失......

CODE：

$zip = 90002;
$pounds = 0.1;

function USPSParcelRate($pounds,$zip) {
$url = "https://secure.shippingapis.com/ShippingAPITest.dll";
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
// parameters to post
curl_setopt($ch, CURLOPT_POST, 1);
$xml = "API=RateV4&XML=<RateV4Request USERID='USERNAME' >
<Revision/>
     <Package ID='1ST'>
          <Service>PRIORITY</Service>
          <ZipOrigination>10025</ZipOrigination>
          <ZipDestination>$zip</ZipDestination>
          <Pounds>$pounds</Pounds>
          <Ounces>0</Ounces>
          <Container></Container>
          <Size>REGULAR</Size>
          <Width></Width>
          <Length></Length>
          <Height></Height>
          <Girth></Girth>
     </Package>
</RateV4Request>";
// send the POST values to USPS
curl_setopt($ch, CURLOPT_POSTFIELDS,$xml);
    $result = curl_exec($ch);
    $data = strstr($result, '<?');
    $xml_parser = xml_parser_create();
    xml_parse_into_struct($xml_parser, $data, $vals, $index);
    xml_parser_free($xml_parser);
    $params = array();
    $level = array();
    echo "TEST";
    foreach ($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($ch);
    echo '<pre>'; print_r($params); echo'</pre>'; // Uncomment to see xml tags
    return $params['RateV4Response']['1ST']['1']['RATE'];
}

USPSParcelRate($pounds,$zip)

Answer 1

你缺少curl_init（）函数，因为没有定义$ ch

$ch = curl_init();

此外，您不打印回复：

**echo** USPSParcelRate($pounds,$zip);

最后，您可以打印curl的响应，更改：

echo "TEST";

为：

print "RESPONSE: $result";

我发现RateV4未经授权，RateV4来自哪里？

TEST HTTP/1.1 200 Connection established

HTTP/1.1 200 OK
Connection: close
Date: Mon, 10 Jun 2013 17:16:17 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET

<Error>
    <Number>80040b1a</Number>
    <Description>API Authorization failure. RateV4 is not a valid API name for this protocol.</Description>
    <Source>UspsCom::DoAuth</Source>
</Error>

希望这至少有助于调试..

Answer 2

RateV4是USPS API的服务名称。
