发布到外部网址使用ajax和php curl无法正常工作(Post to external url is not working using ajax and php curl)

 我有第三方CRM的Web服务。 哪个使用html表单帖子工作正常 
 
 <form method='post' action='http://example.com/myservice/action'>
      <div id='JavascriptWarning' class='warningmessage'>Javascript must be enabled in order to complete this form</div>

      <span class='webformlabel'>Last Name</span>
      <input class='webforminput' name='LastName' type='text'><span class='mandatorymarker'>*</span><br>

      <span class='webformlabel'>First Name</span>
      <input class='webforminput' name='FirstName' type='text'><span class='mandatorymarker'>*</span><br>

<input class='submitbutton' type='submit' id='SubmitButton' value='Submit' disabled='true' onclick='return Validate();'/>
</form>
 
 但我想在ajax或php curl post中使用它 
 
 当我使用ajax时，会出现错误消息 
 
 “请求的资源上没有'Access-Control-Allow-Origin'标头”这是我的代码 
 
function StoreCRMData() {             
          $.ajax({                  
              type: "POST",
              url: "http://example.com/myservice/action",
              data:$('form').serialize(),
              success: function()
              {
                  return false;
              }
          });
      }
 
 PHP卷曲也无法正常工作 
 
<?php
function post_to_url($url, $data) {
   $fields = '';
   foreach($data as $key => $value) { 
      $fields .= $key . '=' . $value . '&'; 
   }
   rtrim($fields, '&');
   $post = curl_init();
   curl_setopt($post, CURLOPT_URL, $url);
   curl_setopt($post, CURLOPT_POST, count($data));
   curl_setopt($post, CURLOPT_POSTFIELDS, $fields);
   curl_setopt($post, CURLOPT_RETURNTRANSFER, 1);
   $result = curl_exec($post);
   curl_close($post);
}

$data = array(
   "LastName" => "My First name",
   "FirstName" => "My Last name"

);
post_to_url("http://example.com/myservice/action", $data);
?>
 
 请帮我解决这个问题 

I have a web service of a third party CRM. Which is working fine using a html form post
 
 <form method='post' action='http://example.com/myservice/action'>
      <div id='JavascriptWarning' class='warningmessage'>Javascript must be enabled in order to complete this form</div>

      <span class='webformlabel'>Last Name</span>
      <input class='webforminput' name='LastName' type='text'><span class='mandatorymarker'>*</span><br>

      <span class='webformlabel'>First Name</span>
      <input class='webforminput' name='FirstName' type='text'><span class='mandatorymarker'>*</span><br>

<input class='submitbutton' type='submit' id='SubmitButton' value='Submit' disabled='true' onclick='return Validate();'/>
</form>
 
But I want to use it in ajax or php curl post
 
When I am using ajax there is error message 
 
“No 'Access-Control-Allow-Origin' header is present on the requested resource” This is my code
 
function StoreCRMData() {             
          $.ajax({                  
              type: "POST",
              url: "http://example.com/myservice/action",
              data:$('form').serialize(),
              success: function()
              {
                  return false;
              }
          });
      }
 
Also PHP curl is not working
 
<?php
function post_to_url($url, $data) {
   $fields = '';
   foreach($data as $key => $value) { 
      $fields .= $key . '=' . $value . '&'; 
   }
   rtrim($fields, '&');
   $post = curl_init();
   curl_setopt($post, CURLOPT_URL, $url);
   curl_setopt($post, CURLOPT_POST, count($data));
   curl_setopt($post, CURLOPT_POSTFIELDS, $fields);
   curl_setopt($post, CURLOPT_RETURNTRANSFER, 1);
   $result = curl_exec($post);
   curl_close($post);
}

$data = array(
   "LastName" => "My First name",
   "FirstName" => "My Last name"

);
post_to_url("http://example.com/myservice/action", $data);
?>
