PHP Curl：提交后从 XML 获取数据

Question

I need to get the response after the form is submitted. The form is submitted to a remote API server.

Here is some of the code:

/*
     * Submits the data via a CURL session
     */
    private function sendDetails(){
        if(true || $_SERVER['REMOTE_ADDR'] != '85.17.27.88'){
            $ch = curl_init($this->parseLink);
            curl_setopt_array($ch, array(
                CURLOPT_FRESH_CONNECT => true,
                CURLOPT_HEADER => false,
                CURLOPT_POST => true,
                CURLOPT_RETURNTRANSFER => true,
                CURLINFO_HEADER_OUT => true,
                CURLOPT_ENCODING => "",
                CURLOPT_POSTFIELDS => $this->parseRequestString($this->result)
            ));

            $this->returned = curl_exec($ch);
            $this->headers = curl_getinfo($ch, CURLINFO_HEADER_OUT);

            $this->result = $this->checkResponse();

            if(!$this->result)
                $this->setError($this->returned);
            elseif(isset($this->p['mobi-submit'])) {
                //redirect mobi users
                $_SESSION['enquire-success-name'] = $this->p['enquire-name'];
                wp_redirect('');
                exit;
            }
        } else {
            echo nl2br(var_export($this->result, true));
            exit;
        }

    }

    /*
     * Checks the response from the webservice for errors / success
     */
    private function checkResponse(){

        libxml_use_internal_errors(true);

        try {
            $xml = new SimpleXMLElement($this->returned);
        } catch(Exception $e){
            return false;
        }       

        if($xml) {
            // If the response has a leadid attrib, then we submitted it successfully.
            if(!empty($xml[0]['leadid'])) {
                if(is_string($xml[0]))
                    $this->returned = $xml[0];
                return true;
            } 
            // If the errorcode is 7, then we have a resubmit and so it was successful.
            elseif(!empty($xml->errors->error[0]['code']) &&  $xml->errors->error[0]['code'] == "7") {
                if(is_string($xml->errors->error[0]))
                    $this->returned = $xml->errors->error[0];
                return true;
            }
            // Otherwise try set the response to be the errormessage
            elseif(!empty($xml->errors->error[0])){
                if(is_string($xml->errors->error[0]))
                    $this->returned = $xml->errors->error[0];
                return false;
            }
            // Otherwise set it to the first xml element and return false.
            else {
                if(is_string($xml[0]))
                    $this->returned = $xml[0];
                return false;
            }
        } 
        // If the xml failed, revert to a more rudimentary test
        elseif(stripos($this->returned, $this->expected) !== false) {
            return true;
        } 
        // If that also fails, expect error.
        else {
            return false;
        }
    }

I did not write this code and I'm not so familiar with curl. I need to get the $xml[0]['leadid'] response into another php file. Is this possible? Do I include the php file that has these function then create a new function? Or do I store it on my database then retrieve it from the database?

Would appreciate any help or further information!

Answer 1

You can get it from $this->returned['leadid'] if returned class member is public OR create a function

public function getReturnedVal($key = 'leadid'){
  if(isset($this->returned[$key])){
    return $this->returned[$key];
  }
  return "";
}

Answer 2

正如您在问题中所说的那样，最简单的选择而不是处理会话或数据库来存储 API 响应，而是将您的脚本包含在需要数据的 PHP 文件中（ include('curl_api_script_file.php'); ）和然后使用类似@volkinc 建议的函数将数据回显到您需要的 PHP 响应页面中。

Answer 3

You could just use file_put_contents('http://path.to.another.php',$this->returned['leadid']); if you have fopen wrappers enabled. The other php would have to just capture the transferred data.

Answer 4

Ok so I figured this out on my own after playing around with the classes etc. :

//Get the type of lead that is submitted
$lead_type = $insureFormResult->p['enquire-type'];

//Get the leadid from xml
$xml = $insureFormResult->returned;
if($xml){
$xml1 = new SimpleXMLElement($xml);
$leadid = $xml1->xpath("/response/@leadid")[0];
}

Thanks for your answers and inputs though!
