百度搜索API v3版本与soap

技术文档请参考http://dev2.baidu.com/docs.do?product=2#page=File，和http://dev2.baidu.com/docs.do?product=2#page=file1，http://dev2.baidu.com/docs.do?product=2#page=Request_Header

因为在每次访问API时，您需要提供您的token（权限代码）以及要操作的用户名和密码来进行权限认证。

那么如何验证？请看下面的代码：

class Baidu_api {

    //soap连接标识
    private $soap_client;

    public function __construct($service_name)
    {
        $this->soap_client = new SoapClient ( URL . '/sem/sms/v3/' . $service_name . '?wsdl', array ('trace' => TRUE, 'encoding' => 'utf-8') );
        //帐号信息
        $sh_param = array ('username' => USERNAME, 'password' => PASSWORD, 'token' => TOKEN );
        $headers = new SoapHeader ( 'http://api.baidu.com/sem/common/v2', 'AuthHeader', $sh_param );
        $this->soap_client->__setSoapHeaders ( array ( $headers ) );
    }

    //取得公开的函数
    public function get_functions()
    {
        return $this->soap_client->__getFunctions();
    }

    //取得公开函数的参数
    public function get_types()
    {
        return $this->soap_client->__getTypes();
    }

    //执行函数接口
    public function soap_call($function_name, array $arguments, array &$output_headers)
    {
        return $this->soap_client->__soapCall($function_name, $arguments, NULL, NULL, $output_headers);
    }

    public function get_last_request()
    {
        return $this->soap_client->__getLastRequest();
    }

    public function get_last_response()
    {
        return $this->soap_client->__getLastResponse();
    }

}

construct部份就是验证。

如何请求对应的接口，举个例子：在reportservice中的接口getProfessionalReportId

function get_professional_report_id($config)
    {
        $param = array(
            'getProfessionalReportIdRequest' => array(
                'reportRequestType' => $config
            )
        );
        $output = array();
        $output_response = $this->client->soap_call('getProfessionalReportId', $param, $output);
        //保存记录
        $this->baidu_log_mdl->write_log('getProfessionalReportId||' . serialize($output));
        if(isset($output_response->reportId)) return $output_response->reportId;
        return FALSE;
    }
