php - 发送Curl POSted XML时无法解析数据类型错误

我正在尝试将一个LinkedIn注册连接到Zoho的招聘API中
当我使用requestbin时，它看起来应该可以工作，但是当我提交给zoho时，我得到一个错误，无法解析数据类型。
这是关于如何将xml post构造为zoho的api的信息
https://www.zoho.com/recruit/add-records.html
下面是我的代码。对我做错了什么有什么建议吗？

<?php

$post_body = file_get_contents('php://input');
$application = json_decode($post_body);

//shortcodes

$firstname = $application->person->firstName;
$lastname = $application->person->lastName;
$city = $application->location->name;
$email = $application->person->emailAddress;
$headline = $application->person->headline;

  /*
   * XML Sender/Client.
   */
  // Get our XML. You can declare it here or even load a file.
  $xml_builder = "

                  <Candidates>
                  <row no=\"1\">
                  <FL val=\"First name\">{$firstname}</FL>
                  <FL val=\"Last name\">{$lastname}</FL>
                  <FL val=\"Contact address\">{$lastname}</FL>
                  <FL val=\"Email ID\">{$email}</FL>
                  <FL val=\"Current job title\">{$headline}</FL>
                  </row>
                  </Candidates>
                 ";




  // Initialize curl
    $curl = curl_init();



  $opts = array(
    CURLOPT_URL             => 'https://recruit.zoho.com/ats/private/xml/Candidates/addRecords?authtoken=#secrettoken&scope=recruitapi&duplicateCheck=1&xmlData={$xml_builder}',
    CURLOPT_RETURNTRANSFER  => true,
    CURLOPT_CUSTOMREQUEST   => 'POST',
    CURLOPT_POST            => 1,
    CURLOPT_POSTFIELDS      => $xml_builder,
    CURLOPT_HTTPHEADER  => array('Content-Type: text/xml','Content-Length: ' . strlen($xml_builder))
  );

    // Set curl options
    curl_setopt_array($curl, $opts);

    // Get the results
    $result = curl_exec($curl);

    // Close resource
    curl_close($curl);

    echo $result;
    $fp = fopen('zoho.txt', 'w');
    fwrite($fp, $result);
    fclose($fp);



?>

最佳答案

必须指定postfields名称。在您发送的文档（https://www.zoho.com/recruit/add-records.html）之后，您应该从url中删除xmlData和duplicateCheck参数，这是一个post-only api。
我认为您还应该添加xml声明（<?xml version='1.0' standalone='yes'?>）
因此，curlopt_postfields定义的代码如下：

$xml_builder = array(
              'duplicateCheck' => 1 ,
              'xmlData' => "
                           <?xml version='1.0' standalone='yes'?>
                           <Candidates>
                              <row no=\"1\">
                              <FL val=\"First name\">{$firstname}</FL>
                              <FL val=\"Last name\">{$lastname}</FL>
                              <FL val=\"Contact address\">{$lastname}</FL>
                              <FL val=\"Email ID\">{$email}</FL>
                              <FL val=\"Current job title\">{$headline}</FL>
                              </row>
                          </Candidates>"
);

$opts数组应该如下所示：

$opts = array(
    CURLOPT_URL  =>'https://recruit.zoho.com/ats/private/xml/Candidates/addRecords?authtoken=#secrettoken&scope=recruitapi',
    CURLOPT_RETURNTRANSFER  => true,
    CURLOPT_CUSTOMREQUEST   => 'POST',
    CURLOPT_POST            => 1,
    CURLOPT_POSTFIELDS      => $xml_builder
);
