我正在尝试访问 Shopware 的 REST api。我使用的是 Shopware 5.1.3 版。我正在使用文档的代码。
我总是得到一个 http 代码 400（无效或缺少身份验证）。
当我尝试通过 Google Chrome 访问 API 时，它会在使用 http 身份验证登录后工作，因此凭据应该没问题。
我猜 Chrome 发送的身份验证标头与我使用 PHP curl 发送的不同。
使用铬：

用于获取标头信息的额外 PHP curl 指令：
curl_setopt($this->cURL, CURLINFO_HEADER_OUT, true);
print_r(curl_getinfo($this->cURL, CURLINFO_HEADER_OUT ));
我使用的代码：
<?php

//Initializes the cURL instance
$this->cURL = curl_init();
curl_setopt($this->cURL, CURLOPT_RETURNTRANSFER, true);

curl_setopt($this->cURL, CURLOPT_HTTPHEADER, array(

));
curl_setopt($this->cURL, CURLINFO_HEADER_OUT, true);
}
public function call($url, $method = self::METHOD_GET, $data = array(), $params = array())
{
if (!in_array($method, $this->validMethods))
{
throw new Exception('Invalid HTTP-Methode: ' . $method);
}
$queryString = '';
if (!empty($params))
{
$queryString = http_build_query($params);
}
$url = rtrim($url, '?') . '?';
$url = $this->apiUrl . $url . $queryString;
$dataString = json_encode($data);
curl_setopt($this->cURL, CURLOPT_URL, $url);
curl_setopt($this->cURL, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($this->cURL, CURLOPT_POSTFIELDS, $dataString);
$result = curl_exec($this->cURL);
dd(curl_getinfo($this->cURL, CURLINFO_HEADER_OUT ));
$httpCode = curl_getinfo($this->cURL, CURLINFO_HTTP_CODE);

echo "<h2>Could not decode json</h2>";

echo "<pre>" . print_r($result, true) . "</pre>";
return;
}
if (!isset($decodedResult['success']))

编辑：找到一个php 错误报告，其中指出 PHP 与 Windows 版本 5.6 及更高版本存在错误。我在 Windows 上使用 XAMP。我打算在linux上试试看它是否有效。
