php - 使用curl来使用这个Web服务

Question

我在使用CURL消费网络服务时看到了这篇文章：Consume WebService with php

我试图遵循它，但没有运气。我上传了一张我正在尝试访问的网络服务的照片。假设URL为：

，我将如何根据以下示例制定我的请求

https://site.com/Spark/SparkService.asmx?op=InsertConsumer

我尝试了这个，但它只返回一个空白页：

 $url = 'https://xxx.com/Spark/SparkService.asmx?op=InsertConsumer?NameFirst=Joe&NameLast=Schmoe&PostalCode=55555&EmailAddress=joe@schmoe.com&SurveyQuestionId=76&SurveyQuestionResponseId=1139';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $result = curl_exec($ch);
    curl_close($ch);

    $xmlobj = simplexml_load_string($result);
    print_r($xmlobj);

Answer 1

真的，你应该看看SOAP extension。如果它不可用或由于某种原因你必须使用cURL，这是一个基本框架：

<?php

  // The URL to POST to
  $url = "http://www.mysoapservice.com/";

  // The value for the SOAPAction: header
  $action = "My.Soap.Action";

  // Get the SOAP data into a string, I am using HEREDOC syntax
  // but how you do this is irrelevant, the point is just get the
  // body of the request into a string
  $mySOAP = <<<EOD
<?xml version="1.0" encoding="utf-8" ?>
<soap:Envelope>
  <!-- SOAP goes here, irrelevant so wont bother writing it out -->
</soap:Envelope>
EOD;

  // The HTTP headers for the request (based on image above)
  $headers = array(
    'Content-Type: text/xml; charset=utf-8',
    'Content-Length: '.strlen($mySOAP),
    'SOAPAction: '.$action
  );

  // Build the cURL session
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_POST, TRUE);
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $mySOAP);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

  // Send the request and check the response
  if (($result = curl_exec($ch)) === FALSE) {
    die('cURL error: '.curl_error($ch)."<br />\n");
  } else {
    echo "Success!<br />\n";
  }
  curl_close($ch);

  // Handle the response from a successful request
  $xmlobj = simplexml_load_string($result);
  var_dump($xmlobj);

?>

Answer 2

该服务要求您进行POST，而您正在进行GET（curl默认为HTTP URL）。加上这个：

curl_setopt($ch, CURLOPT_POST);

并添加一些错误处理：

$result = curl_exec($ch);
if ($result === false) {
    die(curl_error($ch));
}

这是最好的答案，因为一旦你需要登录就可以使用它 从webservices（第三方站点数据）获取一些数据。

$tmp_fname = tempnam("/tmp", "COOKIE"); //create temporary cookie file

$post = array(
    'username=abc@gmail.com',
    'password=123456' 
); 

$post = implode('&', $post); 

//login with username and password
$curl_handle = curl_init ("http://www.example.com/login");

//create cookie session 
curl_setopt ($curl_handle, CURLOPT_COOKIEJAR, $tmp_fname);  

curl_setopt ($curl_handle, CURLOPT_RETURNTRANSFER, true); 

curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $post); 

$output = curl_exec ($curl_handle);

//Get events data after login 
$curl_handle = curl_init ("http://www.example.com/events");  

curl_setopt ($curl_handle, CURLOPT_COOKIEFILE, $tmp_fname); 

curl_setopt ($curl_handle, CURLOPT_RETURNTRANSFER, true); 

$output = curl_exec ($curl_handle);

//Convert json format to array
$data = json_decode($output); 

echo "Output : <br> <pre>";

   print_r($data);

echo "</pre>";
