php - USPS : API Authorization failure

为什么费率不适用于USPS？我正在使用ratev4，但出现错误:

错误:

API Authorization failure. RateV4 is not a valid API name for this protocol.
UspsCom::DoAuth

这是我的代码:

<?php
$devurl = "testing.shippingapis.com/ShippingAPITest.dll";
$puburl = "https://secure.shippingapis.com/ShippingAPITest.dll";

$service = "RateV4";
$userid = "690DEVBL1739";

$xml = rawurlencode('<RateV4Request USERID="xxxxx">
    <Revision/>
    <Package ID="1ST">
        <Service>FIRST CLASS</Service>
        <FirstClassMailType>LETTER</FirstClassMailType>
        <ZipOrigination>44106</ZipOrigination>
        <ZipDestination>20770</ZipDestination>
        <Pounds>1</Pounds>
        <Ounces>0.0</Ounces>
        <Container/>
        <Size>REGULAR</Size>
        <Machinable>true</Machinable>
    </Package>
    </RateV4Request>');

    $request = $devurl . "?API=" . $service . "&xml=" . $xml;


    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $request);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_HTTPGET, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);



    $response = curl_exec($ch);
    curl_close($ch);

    echo "<pre>";
    print_r($response);
    echo "</pre>";

最佳答案

我在测试Ratev4(对于国际运输来说是v2)时遇到了相同的问题。只是要求他们轻松地将您转移到固定的产品上，但是请确保您使用正确的网址。
除此之外，据我了解，您的设置也无法正常工作，因为您要求的是头等舱的价格，重量是1磅。头等舱最多升至13盎司...
