无法打开流：权限被拒绝 - Codeigniter

Question

我正在尝试使用 file_put_contents 通过 REST API 上传文件（图像）。但是，它给出了错误：- 无法打开流：权限被拒绝。

我已经解决了这里的大部分问题并尝试了几乎所有事情

• 将所有者更改为 root 或 apache
• 将组更改为 root 或 apache
• 将权限更改为 755 或 777
• 还有其他选项

我仍然不确定出了什么问题，需要一些帮助。

这是我上传文件的代码。

public function tryImage_post(){
        $image = base64_decode($this->input->post("img_front"));
        $image_name = md5(uniqid(rand(), true));
        $filename = $image_name . '.' . 'png';
        //rename file name with random number
        $path = FCPATH."img/".$filename;
        //image uploading folder path
        file_put_contents($path . $filename, $image);
        // image is bind and upload to respective folde
    }

错误信息：-

<p>Message:  file_put_contents(/var/www/html/development/img/8f2e7959de8beb89ba5e304a6e69d894.png8f2e7959de8beb89ba5e304a6e69d894.png): failed to open stream: Permission denied</p>

Answer 1

试试这个，改变目录权限，

chmod -R 777 var/www/html/development/img

之后，更改您的代码，如下所示。

public function tryImage_post(){
    $image = base64_decode($this->input->post("img_front"));
    $image_name = md5(uniqid(rand(), true));
    $filename = $image_name . '.' . 'png';
    //rename file name with random number
    $path = FCPATH."img/".$filename;
    //image uploading folder path
    file_put_contents($path, $image);
    // image is bind and upload to respective folde
}

Answer 2

 public function tryImage_post(){
    $image = base64_decode($this->input->post("img_front"));
    $image_name = md5(uniqid(rand(), true));
    $filename = $image_name . '.' . 'png';
    //rename file name with random number
    file_put_contents("img/".$filename, $image);
     //image uploading folder path

}
