这将是一个长镜头，因为我真的不知道该问什么。
我在app / code / local / ParcelMonkeyLMc中创建了一个自定义送货方式。我希望它能从parcelmonkey.co.uk API中读取。
我的API在单独的php文件中工作正常，但是当我将代码移到carrier.php时，它似乎无法正常工作。
在公共函数collectRates中，我有以下代码：
$quoterequest = array('parcelmonkey.request' => array(
'login' => array(
'version' => $version,
'username' => $username,
'password' => $password,
'test' => $testflag
),
'requesttype' => 'quote',
'quote' => array(
'packages' => array(
'noofpackages' => 1,
'package1' => array(
'length' => 10,
'width' => 10,
'height' => 10,
'weight' => 1.5
),
),
'insurance_cover' => 0.00,
'collection' => array(
'address' => array(
'postcode' => 'PR7 1DB',
'country' => 'United Kingdom'
)
),
'delivery' => array(
'address' => array(
'postcode' => 'NW1 4RY',
'country' => 'United Kingdom'
)
)
)
)
);
$quotereply=pmGetQuote($quoterequest, $pmapi100url);
pmGetQuote以及其他parcelmonkey相关功能都在页面顶部。如果有人需要知道我可以发布的确切代码。
$ quotereply是对parcelmonkey的查询结果。它看起来像这样：
Array ( [replycode] => 200 [replymessage] => success [replytype] => quote [quote] => Array ( [services] => Array ( [noofservices] => 2 [service1] => Array ( [name] => TestService1Before12am [description] => Test Service 1 Before 12am [carrier] => Camel [price] => 10 [vat] => 0 [vat_rate] => 0 [insurance_cost] => 0 [insurance_cover] => 0 ) [service2] => Array ( [name] => TestService2Anytime [description] => Test Service 2 Anytime [carrier] => Pigeon [price] => 5 [vat] => 0 [vat_rate] => 0 [insurance_cost] => 0 [insurance_cover] => 0 ) ) ) [custom] => Array ( [data] => [orderid] => ) )
在单独的php文件中，我可以抓取特定字段，如下所示：
$num = $quotereply['quote']['services']['noofservices'];
然而，当我在carrier.php中尝试这个时，我得到一个null。我知道这很长，但我不确定你们需要什么细节。
我有没有理由突然得到一个零而不是一个值？
由于
========================
编辑： 根据要求，我放在Carrier.php中的所有ParcelMonkey函数。我发现函数 sendandgetreply 会返回错误，“通信错误：响应时出错”。这不会发生在独立的PHP文件中。
$username = 'username'; /* MODIFY ME */
$password = 'password'; /* MODIFY ME <- note, also referred to as key. */
$version = '100'; /* Protocol version. */
$testflag = '1'; /* Test flag, 0=live, 1=test. MODIFY ME WHEN YOU GO LIVE */
$pmapi100url = 'http://www.parcelmonkey.co.uk/api/pmapi100.php';

答案 0 :(得分：0)
我已经想到了这一点，基本上是以下代码：
$username = 'username'; /* MODIFY ME */
$password = 'password'; /* MODIFY ME <- note, also referred to as key. */
$version = '100'; /* Protocol version. */
$testflag = '1'; /* Test flag, 0=live, 1=test. MODIFY ME WHEN YOU GO LIVE */
$pmapi100url = 'http://www.parcelmonkey.co.uk/api/pmapi100.php';
需要在 collectRates 功能中。
经过多次头部刮擦后这么简单的修复。
