如何使用 cURL 在 php 中發布表單數據？

Question

我有以下命令，它使用 --form/--F 選項，我知道它正在工作：

curl  --form "file=@/home/USERNAME/import.csv" https://apiprovider.com/api/v0/imports\?token\=[KEY]

我需要通過 php 運行這個命令，但我遇到了問題，大概是表單文件數據。 我嘗試了以下操作，但是 echo 或 var_dumping 結果似乎沒有顯示任何內容，只是一個空白頁或一個空白字符串。

<?php 
$target_url = 'https://apiprovider.com/api/v0/imports?token=[KEY]'
$file_name_with_full_path ='/home/USERNAME/import.csv';
$post = array('file'=>'@'.$file_name_with_full_path);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_VERBOSE,true);
$result=curl_exec ($ch);
curl_close ($ch);
var_dump($result);?>

我怎樣才能讓這個命令在 PHP 中工作？

Answer 1

由於到目前為止沒有答案是正確的（至少不是在 php 5.6+ 中使用的方法），所以這里是：等效的 php curl_ 代碼將是：

$ch = curl_init ( 'https://apiprovider.com/api/v0/imports?token=[KEY]' );
curl_setopt_array ( $ch, array (
        CURLOPT_POST => 1,
        CURLOPT_POSTFIELDS => array (
                'file' => new CURLFile ( '/home/USERNAME/import.csv' ) 
        ) 
) );
curl_exec ( $ch );

（我還建議將 CURLOPT_ENCODING 設置為空字符串，特別是如果您希望響應是可壓縮的，這相當於將--compressed添加到 curl 命令行，並且可能會加快速度）

試試這個：

<?php 
$target_url = 'https://apiprovider.com/api/v0/imports?token=[KEY]'
$file_name_with_full_path ='/home/USERNAME/import.csv';
$post = array('file'=>'@'.$file_name_with_full_path);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_VERBOSE,true);
$result = curl_exec ($ch);

$curlresponse = json_decode($result, true);

var_dump($curlresponse);
?>

一種方法是對 5.5 以上的 PHP 版本使用CURLFile而不是 @

$target_url = 'https://apiprovider.com/api/v0/imports?token=[KEY]'
$file_name_with_full_path ='/home/USERNAME/import.csv';
// Create a CURLFile object
$cfile = new CURLFile($file_name_with_full_path,mime_content_type($file_name_with_full_path),'imported_csv');    
// Assign POST data
$post = array('imported_csv_file' => $cfile);    
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_VERBOSE,true);
$result=curl_exec ($ch);
curl_close ($ch);
var_dump($result);

Answer 4

也許這樣的事情可以工作：

<?php 
$target_url = 'https://apiprovider.com/api/v0/imports?token=[KEY]'
$file_name_with_full_path ='/home/USERNAME/import.csv';
$post = array('file'=>'@'.$file_name_with_full_path);

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL,$target_url);
curl_setopt($curl, CURLOPT_POST,1);
curl_setopt($curl, CURLOPT_POST, count($post)
curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,true);
curl_setopt($curl, CURLOPT_VERBOSE,true);
$result = curl_exec($curl)
if(!$result){
    die('Error: "' . curl_error($curl) . '" - Code: ' . curl_errno($curl));
}
curl_close($curl);
var_dump($result);
?>

使用這個庫https://github.com/php-curl-class/php-curl-class然后

$curl = new Curl();
$curl->post('https://www.example.com/login/', array(
    'username' => 'myusername',
    'password' => 'mypassword',
));

您需要讀取文件數據，然后在帖子字段上附加數據。

試試這個，這應該有效。 如果不起作用，請確保fread()可以讀取您的文件。 由於多種原因，閱讀可能會失敗。

$target_url = 'https://apiprovider.com/api/v0/imports?token=[KEY]'

$file_name_with_full_path ='/home/USERNAME/import.csv';
$fileHandler = fopen($file_name_with_full_path, 'r');
$fileData = fread($fileHandler, filesize($file_name_with_full_path));

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, target_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");

$headers = array('file'=>'@'.$file_name_with_full_path);

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_INFILE, $fileHandler);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($file_name_with_full_path));

curl_setopt($ch, CURLOPT_POSTFIELDS, $fileData);

$result = curl_exec($ch);

curl_close ($ch);
var_dump($result);

Answer 7

這對我有用。 你可以試試

  $authHeader = array('Accept: application/form-data');

  $post_fields =  "client_id=" . $client_id . "&client_secret=" . $client_secret;

  send_curl_request("POST", $authHeader, $url, $post_fields);

function send_curl_request($method, $headers, $url, $post_fields){
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL,$url);
  if(count($headers) > 0){
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    //echo '<br> HEADER ADDED<br><br>';
  }
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
  if($method == "POST"){
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
    //echo '<br> POST FIELDS ADDED<br><br>';
  } 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_VERBOSE,true);
  $result = curl_exec($ch);
curl_close($ch);
return $result;
}
