如何调试错误"Deprecated: curl_setopt():"

Question

我有一个通过API上传PDF文件的旧脚本。我收到错误消息：

已弃用：curl_setopt((：文件的@filename API 的用法 不推荐上传。请改用 CURLFile 类。

这是相关的代码(我认为这就是全部(。错误指向以下行：curl_setopt( $curl_handle, CURLOPT_POSTFIELDS, $postFields )。

//Upload the file
function uploadPdf( $api, $lead_id, $rev, $existing_files = array() ) {
if ( ! file_exists( SERVERPATH . "quotes/quote-". $this->id .".pdf" ) )
$this->createQuotePdf();
$files_array = array( array( 'entityType'=>'files', 'name'=>"quote-". $this->id .".pdf" ) );
// if ( $this->upfile && ! file_exists( SERVERPATH . "uploads/" . $upfile ) )
//  $files_array[] = array( array( 'entityType'=>'files', 'name'=> $upfile ) );
foreach ( $existing_files as $file ) {
$files_array[] = (array) $file;
}
//this request gives us the URLs to upload to
$result = $api->editLead( array( 'leadId' => $lead_id, 'rev'=>'REV_IGNORE', 'lead'=> array( 'file' => $files_array ) ) );
//Upload the Quote file
$postFields = array();      
$postFields['file'] = "@" . SERVERPATH . "quotes/quote-". $this->id .".pdf";
$postFields['type'] = "application/pdf";
$curl_handle = curl_init();
$file = array_pop( $result->file );
curl_setopt( $curl_handle, CURLOPT_URL, $file->uri );
curl_setopt( $curl_handle, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $curl_handle, CURLOPT_POST, true );
curl_setopt( $curl_handle, CURLOPT_USERPWD, USERNAME . ":" . API_KEY );
curl_setopt( $curl_handle, CURLOPT_POSTFIELDS, $postFields );
//execute the API Call
$return  = curl_exec( $curl_handle ) ;
$this->uploadUpfile($api, $lead_id);
return $return;
}

我的知识非常基础。但我试图替换：

$postFields['file'] = "@" . SERVERPATH . "quotes/quote-". $this->id .".pdf";
$postFields['type'] = "application/pdf";

跟

$postFields['file'] = curl_file_create(SERVERPATH . "quotes/quote-". $this->id .".pdf", 'application/pdf', SERVERPATH . "quotes/quote-". $this->id .".pdf");

执行上述操作已摆脱错误，但是我实际上无法打开上传文件的潜在问题仍然存在。所以我想知道我是否做错了什么？

从 PHP 5.5 及更高版本开始，您应该使用 CURLFile 上传文件，我已经发布了描述 CURLFile 和正常文件上传的完整答案，您可以在此处查看该答案。

您可以按如下方式使用 CURLFile，请根据需要随意调整代码：

//Upload file using CURLFile
function upload($target, $postFields){
$file = $postFields['file'];
$cFile = new CURLFile($file,$postFields['type'], $file);
$data = array(
'file' => $cFile,
'type' => $postFields['type'],
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $target);
curl_setopt($curl, CURLOPT_HEADER  , true); //we need header
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // stop verifying certificate
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($curl, CURLOPT_POST, true); // enable posting
curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // post images 
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); // if any redirection after upload
curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true);
$r = curl_exec($curl);
if (curl_errno($curl)) {
$error = curl_error($curl);
print_r($error);
} else {
// check the HTTP status code of the request
$resultStatus = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if ($resultStatus != 200) {
print_r($resultStatus);
}else{
//successfull
print_r($r);
}
}
curl_close($curl);
}

由于您的文件和文件类型位于名为$postFields的数组中，因此您可以按如下方式调用上述函数：

upload($target, $postFields);

其中$target是您调用以上传文件的链接。
