我正在尝试访问Australia Post API以验证地址，但是我无法使用PHP或CLI通过cURL授权调用。
以下Wget CLI调用按预期工作并返回XML：
wget --user=username@domain.com.au --password=pass https://api.auspost.com.au/ValidateAddress.xml?addressLine1=31+test+street\&suburb=Adelaide\&postcode=5000\&state=SA\&country=Australia
来自Wget的CLI日志：

但是，以下cURL CLI调用不会：
curl -u username@domain.com.au:pass https://api.auspost.com.au/ValidateAddress.xml?addressLine1=31+test+street\&suburb=Adelaide\&postcode=5000\&state=SA\&country=Australia -v
cURL日志：

< HTTP/1.1 401 Authorization Required
如下所示，使用auth哈希传递'Authorization'标头也会导致401错误。
curl -H 'Authorization: Basic auth_hash_here' https://api.auspost.com.au/ValidateAddress.xml?addressLine1=31+test+street\&suburb=Adelaide\&postcode=5000\&state=SA\&country=Australia -v
最终，我需要在PHP中调用它（理想情况下通过Guzzle调用它，但如果我能使它工作，则需要使用cURL！）。下面是我试过的PHP代码没有成功。
$service_url = 'https://api.auspost.com.au/ValidateAddress.xml?addressLine1=31+test+street&suburb=Adelaide&postcode=5000&state=SA&country=Australia';
$curl = curl_init($service_url);
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_USERPWD, "username@domain.com.au:pass");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE);
$curl_response = curl_exec($curl);
var_dump($curl_response);
我已经通过Chrome REST客户端成功运行了该呼叫，并且可以通过Chrome的网络检查员看到正在通过该呼叫发送的标头。
用户名和密码详细信息正确无误，并经过多次验证。
任何人都有任何关于如何在PHP中使用它的建议吗？
