多部分表单文件上传POST PHP cURL

标签： php api post curl multipartform-data

我想使用PHP和cURL通过http POST发送文件。

除了使用'application / json'发布的文件之外，表单POST工作正常。根据我的理解，这需要是多部分/形式。

我得到的错误是Notice: Array to string conversion在线curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

如果有人能提供帮助那就太棒了！

PHP 

$orgID = (is_numeric($_POST['orgID']) ? (int)$_POST['orgID'] : 0);
$noteTitle = (isset($_POST['noteTitle']) ? $_POST['noteTitle'] : null);
$noteBody = (isset($_POST['noteBody']) ? $_POST['noteBody'] : null);

if(isset($_FILES['file']['tmp_name'])){

    $ch = curl_init();
    $cfile = new CURLFILE($_FILES['file']['tmp_name'], $_FILES['file']['type'], $_FILES['file']['name']);
    $data = array();                

    $data["TITLE"] = "$noteTitle";
    $data["BODY"] = "$noteBody";
    $data["LINK_SUBJECT_ID"] = "$orgID";
    $data["LINK_SUBJECT_TYPE"] = "Organisation";        
    $data['FILE_ATTACHMENTS']['FILE_NAME'] = $_FILES['file']['name'];
    $data['FILE_ATTACHMENTS']['CONTENT_TYPE'] = $_FILES['file']['type'];
    $data['FILE_ATTACHMENTS']['URL'] = $_FILES['file']['tmp_name'];

    $localFile = $_FILES['file']['tmp_name'];
    $fp = fopen($localFile, 'r');       

    $headers = array(
        "authorization: Basic xxx",
        "cache-control: no-cache",
        "content-type: multipart/form-data",
        "postman-token: xxx"
    );

    curl_setopt($ch, CURLOPT_URL, "https://api.insight.ly/v2.1/Notes");
    curl_setopt($ch, CURLOPT_UPLOAD, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 86400); // 1 Day Timeout
    curl_setopt($ch, CURLOPT_INFILE, $fp);
    curl_setopt($ch, CURLOPT_NOPROGRESS,false); 
    curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
    curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localFile));
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    $response = curl_exec($ch);

    if ($response === true) {
        $msg = 'File uploaded successfully.';    
    }
    else {
        $msg = curl_error($ch);         
    }

    curl_close ($ch);

    $return = array('msg' => $msg);

    echo json_encode($return);
}

我看到的一个遗漏是您需要将$cfile对象添加到$data数组中。再加上萨米尔的回答，这应该可以让你们摆平。

您需要为要发布的数据构建查询字符串。使用http_build_query 

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

嗨，我已经找到了问题。

我的参数在api端点上设置不正确。需要设置note_id（c_id）

但我现在遇到的问题是立即发布所有数据。我在创建注释后发布文件，从而为我发布文件的注释ID。任何人都可以帮忙吗？我可以发一个新问题。

请参阅以下更新代码：

//$orgID = (is_numeric($_POST['orgID']) ? (int)$_POST['orgID'] : 0);
//$noteTitle = (isset($_POST['noteTitle']) ? $_POST['noteTitle'] : null);
//$noteBody = (isset($_POST['noteBody']) ? $_POST['noteBody'] : null);

$noteID = (isset($_POST['noteID']) ? $_POST['noteID'] : null);

$localFile = $_FILES['file']['tmp_name'];
$fp = fopen($localFile, 'r');

$curl = curl_init();

$cfile = new CURLFILE($_FILES['file']['tmp_name'], $_FILES['file']['type'], $_FILES['file']['name']);
$data = array();                
//$data["TITLE"] = "$noteTitle";
//$data["BODY"] = "$noteBody";
//$data["LINK_SUBJECT_ID"] = "$orgID";
//$data["LINK_SUBJECT_TYPE"] = "Organisation";        
$data['FILE_ATTACHMENTS'] = $cfile;

curl_setopt_array($curl, array(
  CURLOPT_UPLOAD => 1,
  CURLOPT_INFILE => $fp,
  CURLOPT_NOPROGRESS => false, 
  CURLOPT_BUFFERSIZE => 128,
  CURLOPT_INFILESIZE => filesize($localFile),
  CURLOPT_URL => "https://api.insight.ly/v2.1/Notes/?c_id=" . $noteID . "&filename=" . $_FILES['file']['name'],
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => $data,      
  CURLOPT_HTTPHEADER => array(
    "authorization: Basic xxx",
    "cache-control: no-cache",
    "content-type: multipart/form-data",
    "postman-token: xxx"
  ),
));
$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

HTML 

<form method="POST" action="formSend.php" enctype="multipart/form-data">
    //<input type="text" value="" name="orgID">
    //<input type="text" value="" name="noteTitle">
    //<input type="text" value="" name="noteBody"> 
    <input type="text" value="" name="noteID">
    <input name="file" type="file" id="file"/>
    <input type="submit" value="Submit" name="btnUpload"/>
</form>

如果有人感兴趣，这是我使用fpdf从Web表单生成PDF文档然后自动发送而不是文件上传的解决方案。 FPDF file ---> send via CURL automatically NOT with file upload

这一切很快变得非常令人困惑和“矛盾”！ 由于cUrl非常灵活和强大，因此使用上下文的微小差异会产生巨大影响，并可能导致不存在追逐错误的日子。

第二，您要发布到的URL /端点也可以具有自己的“实现”和期望。当经验仅涉及GET请求并且假设/期望基于PHP Super Easy $ _REQUEST

时，这种理解会变得复杂

在上述情况下，进行简化：这是一个实时示例，但是postfields（$ post）已从使用的50个奇数减少为几个。这将作为多部分表单数据发布。

以下重要选项是使用CURLOPT_POST和CURLOPT_POSTFIELDS而非NOT CURLOPT_CUSTOMREQUEST的选项。这样做将需要您注意必需的标头，尤其是内容大小标头等。

// Post "field" array. Notice its 1 Dimensional. Else, this should rather accept JSON. simply decode array to json and proceed). Depends what server is expecting - Form data, Form + files, json or maybe just a RAW request body.
$post = array(  
            'RsmMaster1_TSM' => $tsm,
            '__EVENTTARGET' => '__Page',
            '__EVENTARGUMENT' => 'ExcelExport',
            '__VIEWSTATE'  => $viewstate,
            '__VIEWSTATEGENERATOR'  => $viewstategenerator,
            '__EVENTVALIDATION'  => $eventvalidation
 );

// Optional, Required in THIS case because, well gosh darn who knows, as the receiving server admin?
$headers = array(   
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-ZA,en-GB;q=0.8,en-US;q=0.5,en;q=0.3',
                'Referer: https://example.com/Main.aspx'  
            );

// cUrl it into the goal!
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://example.com/Main.aspx');
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');                                                                   
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);    
curl_setopt($ch, CURLOPT_HEADER, 0);
// curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie); // Session maintain!
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_FAILONERROR,    TRUE   );
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE  );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE  );

$content = curl_exec($ch);
curl_close($ch);
