上传图片在Android应用中不起作用，但在Codeigniter中的Postman插件中工作

Question

我面临的问题如下：

我在codeigniter中开发API，用于将上传图像转换为服务器的特定文件夹。当我检查邮递员工作正常。但是，当我检查Android应用程序不能正常工作。

请给我一些建议。

提前致谢。

我的代码如下：

public function updateimage_post() {
    if(!$this->post('UserID')) {
        $status = [
            ['status' => 400 ,  'message' => 'UserID is required.'],
        ];
        $this->response($status, REST_Controller::HTTP_BAD_REQUEST);
    } else {
        $this->db->where(array('ID' => $this->post('UserID')));
        $db_result = $this->db->get('userregistration');

        if ($db_result && $db_result->num_rows() > 0) {
            if(isset($_FILES['ProfilePicture']['name'])) {
                $info = pathinfo($_FILES['ProfilePicture']['name']);
                $ext = $info['extension'];
                if (($ext == "GIF" || $ext == "PNG" || $ext == "JPG" || $ext == "jpg" || $ext == 'gif' || $ext == 'png' || $ext == 'jpeg') && ($_FILES["ProfilePicture"]["type"] == "image/PNG" || $_FILES["ProfilePicture"]["type"] == "image/GIF" || $_FILES["ProfilePicture"]["type"] == "image/JPG" || $_FILES["ProfilePicture"]["type"] == "image/jpg" ||$_FILES["ProfilePicture"]["type"] == "image/jpeg" || $_FILES["ProfilePicture"]["type"] == 'image/gif' || $_FILES["ProfilePicture"]["type"] == 'image/png') && ($_FILES["ProfilePicture"]["size"] < 30485760)) {
                    $file = $info['filename'];
                    $filename = 'frontuser' . '_' . uniqid() . '.' . $ext;
                    $target = './uploads/frontusers/' . $filename;
                    $file = $_FILES['ProfilePicture']['tmp_name'];
                    if (move_uploaded_file($file, $target)) {
                        $data = array(
                            'ProfilePicture' => $filename,
                            'ModifiedOn' => date('Y-m-d H:m:s'),
                        );
                        $result = $this->db->update('userregistration', $data, array('ID' => $this->post('UserID')));
                    } else {
                        $status = ['status' => 201 ,  'message' => 'Image not uploaded.'];
                        $this->response($status, REST_Controller::HTTP_OK);
                    }
                } else {
                    $status = ['status' => 201 ,  'message' => 'File is invalid.'];
                    $this->response($status, REST_Controller::HTTP_OK);

                $this->response($status, REST_Controller::HTTP_OK);
            }

            if($result) {
                $status = [
                    'status' => 200,
                    'message' => 'Profile Picture Update Successfully',
                    ];
            } else {
                $status = [
                    'status' => 201,
                    'message' => 'Something went wrong !!',
                    ];
            }
