我需要您帮助修改USPS价格计算器API V4。我的网站目前正在使用V3，并且自API升级到V4后运费计算器停止工作。它只能计算美国某些邮政编码的运费。
以下是Web开发人员使用的代码。我试图将所有“V3”改为“V4”，但没有运气。我猜它比那更复杂。请查看下面的代码并告知我需要做什么。感谢您的帮助。

我是您的代码在USPS（）函数中引用的原始脚本的作者，尽管脚本已经过大量修改，但仍然在USPS（）函数中引用：
//这个剧本由Mark Sanborn在http://www.marksanborn.net

USPS Rate API V4所需的基本请求结构如下：
API=RateV4&XML=<RateV4Request USERID="YOURIDHERE">
<Revision>2</Revision>
<Package ID="1ST">
<Service>ALL</Service>
<ZipOrigination>59759</ZipOrigination>
<ZipDestination>90210</ZipDestination>
<Pounds>5</Pounds>
<Ounces>5</Ounces>
<Container />
<Size>REGULAR</Size>
<Width>2</Width>
<Length>1</Length>
<Height>3</Height>
<Girth>10</Girth>
<Machinable>false</Machinable>
</Package>
</RateV4Request>
我拿了你发布的内容并对其进行了修改，向你展示了对USPS V4 API的基本示例请求：

// set the target url
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);
// You would want to actually build this xml using dimensions
// and other attributes but this is a bare minimum request as
// an example.
$data = "API=RateV4&XML=<RateV4Request USERID=\"{$username}\">
<Revision>2</Revision>
<Package ID=\"1ST\">
<Service>ALL</Service>
<ZipOrigination>{$originZip}</ZipOrigination>
<ZipDestination>{$destZip}</ZipDestination>
<Pounds>{$pounds}</Pounds>
<Ounces>{$ounces}</Ounces>
<Container />
<Size>REGULAR</Size>
<Width>2</Width>
<Length>1</Length>
<Height>3</Height>
<Girth>10</Girth>
<Machinable>false</Machinable>
</Package>
</RateV4Request>";
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec ($ch);
return $result;
}
var_dump(
USPS(5, 1, '59759', '90210')
);
请注意，在请求期间可以指定更多可以影响费率的包属性，以及用于国际费率的完全不同的API。
