这是一个完整的脚本，它将创建XML结构，将它们发送到XML并给出响应。

<?php
// ACCESS: You will get these after you register on UPS Website
$AccessLicenseNumber = 'xxxxxxx';
$UserID = 'xxxxxxx';
$Password = 'xxxxxxxxx';
// REQUEST *********************************
$CustomerContext = "something";
$RequestAction = "ShipConfirm";     // These values are contained in documentation 
$RequestOption = "nonvalidate";
.........
.........
......... 
And many others ...

这是XML结构！！我已经阅读了整个文档，写下了每个元素的必要信息，这样当您插入超过30个字符的名称时，您可以轻松地调试XML

重要提示：你可能已经注意到我只有一个头文件，即使文档说它需要两个头文件，这是真的。但我试图只发送一个，它的工作，所以它没有必要有两个。
1.发货确认请求

$domtree = new DOMDocument('1.0');

// <AccessRequest>
$AccessRequest = $domtree->createElement("AccessRequest");
$AccessRequest->setAttribute("xml:lang", "en_US");
$domtree->appendChild($AccessRequest);

    $AccessRequest->appendChild($domtree->createElement('AccessLicenseNumber', $AccessLicenseNumber));

Here is a for loop which creates as many <Package> elements as you want (You can remove this if you want to send only one PACKAGE)
            for ($i = 0; $i < sizeof($Pack_IDs); $i++) {

            }
        // </Shipment>
        // <LabelSpecification>
        $LabelSpecification = $domtree->createElement('LabelSpecification');
        $ShipmentConfirmRequest->appendChild($LabelSpecification);
            // <LabelPrintMethod>
            $LabelPrintMethod = $domtree->createElement('LabelPrintMethod');
            $LabelSpecification->appendChild($LabelPrintMethod);

现在我们已经准备好并填充了XML结构。我建议您打印XML结构，并仔细地将其与文档进行几次比较，以避免仅仅因为您将某些内容附加到错误的父对象或其他内容而出现许多错误。
这里是您需要的代码，用于发送XML和接收请求。

2.发货确认响应

$domtree->preserveWhiteSpace = true;
$domtree->formatOutput = true;
$xml_string = $domtree->saveXML();

// UPS Address
$url = 'https://wwwcie.ups.com/ups.app/xml/ShipConfirm'; // IMPORTANT: This is a testing URL address, dont be scared to send your request (Real URL is different -> documentation)
// SEND THE REQUEST
$stream_options = array(
    'http' => array(
       'method'  => 'POST',
       'header'  => 'Content-type: application/x-www-form-urlencoded',
       'content' => "$xml_string",
    ),
);
$context  = stream_context_create($stream_options);
$response = file_get_contents($url, null, $context); // Response XML structure

现在，您已经将响应XML结构存储在$response变量中，因此可以访问任何想要的数据

// Response handling
$ShipmentConfirmResponse = new SimpleXMLElement($response);
if ((string)$ShipmentConfirmResponse->Response->ResponseStatusCode == 1) { // If the response is "success" then continue with second request
    // If ShipmentCofirmRequest is successful, send ShipmentAcceptRequest
    $ShipmentDigest = $ShipmentConfirmResponse->ShipmentDigest;
    AcceptRequest($AccessLicenseNumber, $UserID, $Password, $CustomerContext, $ShipmentDigest, $ShipmentID, $connect); // After first successful request call a function which will send AcceptRequest

} else {
    echo $ShipmentConfirmResponse->Response->Error->ErrorDescription;
}

这里有一个发送第二个请求“AcceptRequest”的函数，代码相同，但XML结构不同。

3.发货接受请求

function AcceptRequest ($AccessLicenseNumber, $UserID, $Password, $CustomerContext, $ShipmentDigest) {
    $RequestAction = "ShipAccept";

    $domtree = new DOMDocument('1.0');

    // <AccessRequest>
    $AccessRequest = $domtree->createElement("AccessRequest");
    $domtree->appendChild($AccessRequest);
            // <AccessLicenseNumber>
        $AccessRequest->appendChild($domtree->createElement('AccessLicenseNumber', $AccessLicenseNumber));
            // <UserId>
        $AccessRequest->appendChild($domtree->createElement('UserId', $UserID));
            // <Password>
        $AccessRequest->appendChild($domtree->createElement('Password', $Password));
    // </AccessRequest>
    // <ShipmentAcceptRequest>
    $ShipmentAcceptRequest = $domtree->createElement("ShipmentAcceptRequest");
    $domtree->appendChild($ShipmentAcceptRequest);
            // <Request>
        $Request = $domtree->createElement("Request");
        $ShipmentAcceptRequest->appendChild($Request);
                    // <TransactionReference>
            $TransactionReference = $domtree->createElement("TransactionReference");
            $Request->appendChild($TransactionReference);
                        // <CustomerContext>
                        $TransactionReference->appendChild($domtree->createElement('CustomerContext', $CustomerContext));
                    // </TransactionReference>
                    // <RequestAction>
                    $Request->appendChild($domtree->createElement('RequestAction', $RequestAction));
            // </Request>
            // <ShipmentDigest>
            $ShipmentAcceptRequest->appendChild($domtree->createElement('ShipmentDigest', $ShipmentDigest));
    // </ShipmentAcceptRequest>

然后你再一次用这个代码发送它，然后你需要看看$response变量里面是否成功，你可以存储跟踪ID和运费，并做任何你想做的事情。
重要提示：您还将获得Base64编码的标签图像

4.发货接受响应

$domtree->preserveWhiteSpace = true;
    $domtree->formatOutput = true;
    $xml_string = $domtree->saveXML();
    $url = 'https://wwwcie.ups.com/ups.app/xml/ShipAccept'; // Again testing URL

    $stream_options = array(
        'http' => array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => "$xml_string",
    ),
);
    $context  = stream_context_create($stream_options);
    $response = file_get_contents($url, null, $context);

    $ShipmentAcceptResponse = new SimpleXMLElement($response);

    if ((string)$ShipmentAcceptResponse->Response->ResponseStatusCode == 1) {

        $Tracking_ID = $ShipmentAcceptResponse->ShipmentResults->PackageResults->TrackingNumber;
        $Price = $ShipmentAcceptResponse->ShipmentResults->ShipmentCharges->TransportationCharges->MonetaryValue;
        $ImageBase64 = $ShipmentAcceptResponse->ShipmentResults->PackageResults->LabelImage->GraphicImage;

    } else {
        echo $ShipmentAcceptResponse->Response->Error->ErrorDescription;
    }
}
