upload image error with php class and curl

本文关键字：图像错误类和 curl php | 更新日期: 2023-09-27

hi我有这个代码上传器.php：

class Uploader 
    {
        var $filePath;
        var $uploadURL;
        var $formFileVariableName;
        var $postParams = array ();
        function Uploader($filePath, $uploadURL, $formFileVariableName, $otherParams = false) 
        {
            $this->filePath = $filePath;
            $this->uploadURL = $uploadURL;
            if(is_array($otherParams) && $otherParams != false) 
            {
                foreach($otherParams as $fieldName => $fieldValue) 
                {
                    $this->postParams[$fieldName] = $fieldValue;
                }
            }
            $this->postParams[$formFileVariableName] = "@" . $filePath;
        }
        function UploadFile() 
        {
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $this->uploadURL);
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $this->postParams);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            $postResult = curl_exec($ch);
            if (curl_errno($ch)) 
            {
                print curl_error($ch);
                print "Unable to upload file.";
                exit();
            }
            curl_close($ch);
            return $postResult;
        }
    }

我用的是这样的：

require('uploader.php');
$upload_server = "http://developers.mytech.com.mx/files/api/upload.php";
     $file = $_FILES['archivo']['tmp_name'];
$archivo = $file;
$extension = pathinfo($archivo, PATHINFO_EXTENSION);
$nombre_base = basename($archivo, '.'.$extension);
    $upload = new Uploader($file, $upload_server,'file', array('api_key' => 'ic00n6yokd'));
    $result = $upload->UploadFile();
    if(preg_match("/upload_failed/", $result)){ echo "Upload failed."; }
    if(preg_match("/error_tamano/", $result)){ echo "Archivo muy grande."; }
    if(preg_match("/api_invalida/", $result)){ echo "Invalid API Code."; }
    if(preg_match("/error_type/", $result)){ echo "Archivo no valido."; }
    if(preg_match("/upload_success/", $result)){ echo $result; }

但问题是，wht上传的是作为文件的tmpname，而不是图像但如果我更改这一行：$file=$_FILES["archivo"]["tmp_name"]；到$file=$_FILES[‘archivo’][‘name’]；

我得到这个错误：创建formpost数据失败

我的问题是如何正确地使用这个类，这样我就可以上传图像

也许您应该为图像数据指定标题试试这个：

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'content-type: image/png'
 ));
