我尝试向本地Magento2 rest API发送GET请求，以便在一段时间后获取所有订单。我跟随http://devdocs.magento.com/guides/v2.1/howdoi/webapi/search-criteria.html#simple-search-using-a-timestamp。我使用CakePHP 3.4的Http客户端（https://book.cakephp.org/3.0/en/core-libraries/httpclient.html）并使用Oauth1成功地与Magento集成，并且对http://www.magento.dev.com/rest/V1/stockItems/:productSku等更简单的GET请求没有任何问题。传递搜索条件是一个问题。回复始终为401 Invalid Signature。
使用邮递员，我可以得到对http://www.magento.dev.com/rest/V1/orders?searchCriteria[filter_groups][0][filters][0][field]=created_at&searchCriteria[filter_groups][0][filters][0][value]=2016-07-01 00:00:00&searchCriteria[filter_groups][0][filters][0][condition_type]=gt
这是我到目前为止/我如何发送请求：
在Model / Table / OrdersTable.php中：
public function importNewOrders(\App\Model\Entity\OauthIntegration $integrationDetails)
{
$this->OauthIntegrations = TableRegistry::get('OauthIntegrations');
$this->Orders = TableRegistry::get('Orders');
$timeCutOff = '2015-01-01 00:00:00';
$search = [
'searchCriteria' => [
'filterGroups' => [
0 => [
'filters' => [
0 => [
'field' => 'created_at',
'value' => $timeCutOff,
'condition_type' => 'gt'
]
]
]
]
]
];
// 'searchCriteria[filter_groups][0][filters][0][field]' => 'created_at',
// 'searchCriteria[filter_groups][0][filters][0][value]' => $timeCutOff,
// 'searchCriteria[filter_groups][0][filters][0][condition_type]' => 'gt'
$action = '/V1/orders';
$type = "GET";
$response = $this->OauthIntegrations->sendRequest(
$integrationDetails,
$action,
$type,
'',
$search);
Log::write('debug', $response->body());
return $response;
}
，在Model \ Table \ OauthIntegrationsTable.php中：
public function sendRequest(\App\Model\Entity\OauthIntegration $integrationDetails,
string $action, string $method = "GET", string $data = '', array $search = null)
{
$http = new Client([
'auth' => [
'type' => 'oauth',
'consumerKey' => $integrationDetails->oauth_consumer_key,
'consumerSecret' => $integrationDetails->oauth_consumer_secret,
'token' => $integrationDetails->oauth_token,
'tokenSecret' => $integrationDetails->oauth_token_secret
]
]);
$url = $integrationDetails->store_base_url . 'rest' . $action;
if ($method == 'GET'){
if (!isset($search)){
$search = [];
}
$response = $http->get($url, $search, []);
} else if ($method == 'POST'){
$response = $http->post($url, $data, [
'type' => 'json',
]);
} else if($method == 'PUT'){
$response = $http->put($url, $data, [
'type' => 'json',
]);
}
Log::write('debug', 'url: ' . $url . ' and status code: ' . $response->getStatusCode());
return $response;
}
这是错误（我希望）是无效签名响应的原因：

来自Http \ Client \ Oauth.php的代码，其中发生错误：
$pairs = [];
foreach ($args as $k => $val) {
if (is_array($val)) {
sort($val, SORT_STRING);
Log::write('debug', 'about to go through foreach($val as $nestedVal)');
foreach ($val as $nestedVal) {
Log::write('debug', $nestedVal);
$pairs[] = "$k=$nestedVal"; // <<< HERE
}
} else {
$pairs[] = "$k=$val";
}
}
从上面调试导致：
2017-03-28 10:07:01 Debug: about to go through foreach($val as $nestedVal)
2017-03-28 10:07:01 Debug: Array
(
[0] => Array
(
[filters] => Array
(
[0] => Array
(
[field] => created_at
[value] => 2015-01-01 00:00:00
[condition_type] => gt
)
)
)
)
总之，是否可以使用Cake的Http Client将多维数组传递给get请求中的第二个参数？
// Is it possible to replace ['q' => 'widget'] with a multi-dimensional array??
$response = $http->get('http://example.com/search', ['q' => 'widget']);
如果没有，那么使用Cake的Http客户端向http://www.magento.dev.com/rest/V1/orders?searchCriteria[filter_groups][0][filters][0][field]=created_at&searchCriteria[filter_groups][0][filters][0][value]=2016-07-01 00:00:00&searchCriteria[filter_groups][0][filters][0][condition_type]=gt发送GET请求的最佳方式是什么？
提前致谢!!!
答案 0 :(得分：1)
这可能被视为可能的错误。我认为the OAuth specs不考虑URL中的这个PHP样式括号内容，因此对参数进行排序/编码仅限于平面key=value集，即密钥是
searchCriteria[filter_groups][0][filters][0][field]
，值为
created_at
然而，CakePHP OAuth适配器将请求查询字符串解析为可能深度嵌套的数组结构，然后该数组结构将失败，因为它不处理这种情况。
我建议你report this as a possible bug。进一步的问题可能会出现，因为编码似乎是在排序之前应用的，在CakePHP实现中， additonal 参数编码在排序后应用（实际上可能很好，但我不确定）
在修复/增强此功能之前，您可以使用自定义OAuth适配器来“正确”处理事物（无论在此上下文中是什么意思）。这是一个快速而肮脏的例子（适用于我的Magento API）。
创建 src / Http / Client / Auth / AppOAuth.php
<?php
namespace App\Http\Client\Auth;
use Cake\Http\Client\Auth\Oauth;
class AppOAuth extends Oauth
{
protected function _normalizedParams($request, $oauthValues)
{
$query = parse_url($request->url(), PHP_URL_QUERY);
parse_str($query, $queryArgs);
$post = [];
$body = $request->body();
if (is_string($body) &&
$request->getHeaderLine('content-type') === 'application/x-www-form-urlencoded'
) {
parse_str($body, $post);
}
if (is_array($body)) {
$post = $body;
}
$args = array_merge($queryArgs, $oauthValues, $post);
$query = http_build_query($args);
$args = [];
foreach (explode('&', $query) as $value) {
$pair = explode('=', $value, 2);
$args[] =
rawurlencode(rawurldecode($pair[0])) .
'=' .
rawurlencode(rawurldecode($pair[1]));
}
usort($args, 'strcmp');
return implode('&', $args);
}
}
与 \Cake\Http\Client\Auth\Oauth::_normalizedParams()
比较通过在客户端实例的type选项中指定类名来使用它：
'type' => 'AppOAuth',
filter_groups数组中，不应该是filterGroups而不是$search吗？
