php - 需要一个使用 PHP 和 CURL 将 XML 发布到 USPS 地址验证 Web 服务的示例

Question

我尝试过以下方法:

<?php

$user = 'myusername';


$xml_data = "<AddressValidateRequest USERID='$user'>" .
"<IncludeOptionalElements>true</IncludeOptionalElements>" .
"<ReturnCarrierRoute>true</ReturnCarrierRoute>" .
"<Address ID='0'>" .
"<FirmName />" .
"<Address1 />" .
"<Address2>205 bagwell ave</Address2>" .
"<City>nutter fort</City>" .
"<State>wv</State>" .
"<Zip5></Zip5>" .
"<Zip4></Zip4>" .
"</Address>" .
"</AddressValidateRequest>";


$url = "http://production.shippingspis.com/ShippingAPI.dll";


    //setting the curl parameters.
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
   // Following line is compulsary to add as it is:
    curl_setopt($ch, CURLOPT_POSTFIELDS,
                "?API=Verify&XML=" . $xml_data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);
    $output = curl_exec($ch);
    curl_close($ch);



$array_data = json_decode(json_encode(simplexml_load_string($output)), true);

print_r('<pre>');
print_r($array_data);
print_r('</pre>');
echo PHP_EOL;
?>

我没有收到任何响应，也没有收到任何类型的错误。有人能引导我走向正确的方向吗？

我尝试遵循在网上找到的几个示例，但我似乎无法找到解决方案。

我的代码基于这篇文章中的示例:

Send XML data to webservice using php curl

工作代码如下

<?php
$user = 'myusername';
$xml_data = "<AddressValidateRequest USERID='$user'>" .
"<IncludeOptionalElements>true</IncludeOptionalElements>" .
"<ReturnCarrierRoute>true</ReturnCarrierRoute>" .
"<Address ID='0'>" .
"<FirmName />" .
"<Address1>$address1></Address1>" .
"<Address2>$address2</Address2>" .
"<City>$city</City>" .
"<State>$state</State>" .
"<Zip5></Zip5>" .
"<Zip4></Zip4>" .
"</Address>" .
"</AddressValidateRequest>";



$url = "http://production.shippingapis.com/ShippingAPI.dll?API=Verify";


    //setting the curl parameters.
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    // Following line is compulsary to add as it is:
    curl_setopt($ch, CURLOPT_POSTFIELDS,
                'XML=' . $xml_data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);
    $output = curl_exec($ch);
    echo curl_error($ch);
    curl_close($ch);


$array_data = json_decode(json_encode(simplexml_load_string($output)), true);

print_r('<pre>');
print_r($array_data);
print_r('</pre>');
echo PHP_EOL;

Answer 1

这是工作代码。请注意，XML 是在对curl_setopt 的调用中传递的。除了原始 URL 中的拼写错误之外，我还在 $url 变量中包含了“&XML=”，但这不起作用。

<?php
$user = 'myusername';
$xml_data = "<AddressValidateRequest USERID='$user'>" .
"<IncludeOptionalElements>true</IncludeOptionalElements>" .
"<ReturnCarrierRoute>true</ReturnCarrierRoute>" .
"<Address ID='0'>" .
"<FirmName />" .
"<Address1>$address1></Address1>" .
"<Address2>$address2</Address2>" .
"<City>$city</City>" .
"<State>$state</State>" .
"<Zip5></Zip5>" .
"<Zip4></Zip4>" .
"</Address>" .
"</AddressValidateRequest>";



$url = "http://production.shippingapis.com/ShippingAPI.dll?API=Verify";


    //setting the curl parameters.
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    // Following line is compulsary to add as it is:
    curl_setopt($ch, CURLOPT_POSTFIELDS,
                'XML=' . $xml_data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);
    $output = curl_exec($ch);
    echo curl_error($ch);
    curl_close($ch);


$array_data = json_decode(json_encode(simplexml_load_string($output)), true);

print_r('<pre>');
print_r($array_data);
print_r('</pre>');
echo PHP_EOL;
?>
