USPS 价格计算器 V4（更新到 PHP 文件）

Question

在修改 USPS 价格计算器 API V4 方面需要您的帮助。我的网站目前正在使用 V3，并且自从 API 升级到 V4 后运费计算器停止工作。它只能计算美国特定邮政编码的运费。

以下是之前的 Web 开发人员使用的代码。我试图将所有“V3”更改为“V4”，但没有运气。我猜它比这更复杂。请查看下面的代码并告知我需要做什么。提前感谢您的帮助。

--------- 第一个 PHP 文件 -------------------

根据这一行判断，我是您的代码在 USPS() 函数中引用的原始脚本的作者，尽管该脚本已被大量修改：

// 此脚本由 Mark Sanborn 在http://www.marksanborn.net 编写

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>

我采用了您发布的内容并对其进行了修改，以向您展示对 USPS V4 API 的基本示例请求：

<?php

function USPS($pounds, $ounces, $originZip, $destZip) 
{

    // ========== CHANGE THESE VALUES TO MATCH YOUR OWN ===========
    $username = 'YOURAPIUSERNAME'; 
    // ========== CHANGE THESE VALUES TO MATCH YOUR OWN ===========

    $url = "http://Production.ShippingAPIs.com/ShippingAPI.dll";  
    $ch = curl_init();  

    // 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。

如果您无法将这些放在一起，您真的应该考虑我在https://rocketship.it 提供的商业产品，因为它功能齐全，支持多个运营商，最重要的是，当运营商更改他们的 API 时会更新，就像他们在您的案例中所做的那样。
