Question

我为Highrise的API编写了一个非常基本的包装类。它适用于Reads（GET），我刚开始为Creates（POST）测试它。据我所知，这两个请求（一个在命令行，一个通过PHP的cURL库）是相同的。相同的XML，相同的选项设置....只有一个工作，而另一个没有。

感谢任何帮助。我也将此问题发布到37signals开发人员邮件列表，但stackoverflow通常更快地发现我的愚蠢错误......

这是我用PHP的cURL得到的错误（让我觉得Highrise在解析XML字符串时遇到了问题）：

<?xml version="1.0" encoding="UTF-8"?> <errors> <error>First name can't be blank</error> </errors>

这适用于命令行：

curl -u 'my_api_key:X'
    -H 'Content-type: application/xml'
    -d '<?xml version="1.0" encoding="UTF-8"?> <person><first-name>Savos</first-name><last-name>Aren</last-name><title>Archmage</title><company-name>Winterhold College</company-name><contact-data><email-addresses/><phone-numbers><phone-number><number>555-555-5555</number><location>Home</location></phone-number><phone-number><number>555-555-5555</number><location>Work</location></phone-number><phone-number><number>555-555-5555</number><location>Mobile</location></phone-number></phone-numbers><addresses><address><city>Winterhold</city><country>Tamriel</country><state>Skyrim</state><street>Hall of the Elements, College of Winterhold</street><zip>99999</zip><location>Work</location></address></addresses></contact-data></person>'

这是我的包装类：

class HighriseAPICall {
    protected $_timeout = 120;
    protected $_url_prefix = 'https://';
    protected $_url_suffix = '.highrisehq.com';
    protected $_password = 'X';

    protected $_userpwd;
    protected $_url;

    public function __construct($api_key, $username) {
        $this->_userpwd= $api_key . ':' . $this->_password;
        $this->_url = $this->_url_prefix . $username . $this->_url_suffix;
    }

    /**
     * Make the specified API call.
     * @param string $action one of the four HTTP verbs supported by Highrise
     * @param string $resource_name the Highrise resource to be accessed
     * @param string $xml a well-formed XML string for a Highrise create, update, or delete request
     * 
     * $xml parameter should include any query parameters as suggested by Highrise API documentation
     * eg, if you want to GET all People, pass in "/people.xml"
     * and if you want to get People by search term where field=value,
     * then pass in "/people/search.xml?criteria[field]=value"
     */
    public function makeAPICall($action,$resource_name,$xml=null) {
        /* initialize curl session and set defaults for new API call */
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $this->_url . $resource_name);
        curl_setopt($curl, CURLOPT_USERPWD, $this->_userpwd);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
        curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $this->_timeout);
        /* if xml was passed in, set header and postfields */
        if (isset($xml)) {
            curl_setopt($curl, CURLOPT_HTTPHEADER, 'Content-type: application/xml');
            curl_setopt($curl, CURLOPT_POSTFIELDS, "$xml");
        }
        /* set action as custom request */
        curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $action);
        /* get the string response from executing the curl session */
        $result = curl_exec($curl);
        curl_close($curl);

        // return the response as a simpleXMLElement
        try {
                $result_simplexml = new SimpleXMLElement($result);
        }
        catch (Exception $e) {
                throw new Exception("Highrise API Call Error: " . $e->getMessage() . ", Response: " . $result);
        }
        if (!is_object($result_simplexml)) {
                throw new Exception("Highrise API Call Error: Could not parse XML, Response: " . $result);
        }
        return $result_simplexml;
    }

}
?>

Answer 1

尝试这一行而不是你脚本中的内容

   if (isset($xml)) {
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: application/xml'));
        curl_setopt($curl, CURLOPT_POSTFIELDS, $xml);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST ,false);
    }

Answer 2

在我的包装类中，行：

curl_setopt($curl, CURLOPT_HTTPHEADER, 'Content-type: application/xml');

应该是：

curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: application/xml'));

为什么这个cURL请求在命令行上运行，而不是在PHP中？
