Question

具有使用常规格式将图像上传到服务器的功能。他们要求使功能Ctrl + V并加载图像。我正在尝试，某些问题无法解决。

JS：

document.onpaste = function(event) {
  var items = (event.clipboardData || event.originalEvent.clipboardData).items;
  console.log(JSON.stringify(items));
  for (index in items) {
    var item = items[index];
    if (item.kind === 'file') {
      var blob = item.getAsFile();
      var reader = new FileReader();
      reader.onload = function(event) {
        document.getElementById('file-upload').files[0] = event.target.result;
        document.getElementById('up-img').submit();
        //alert(event.target.result);
      };
      reader.readAsDataURL(blob);
    }
  }
}

表单代码：

<form action="/upload-img.php" enctype="multipart/form-data" method="POST" id="up-img">
<label for="file-upload" class="custom-file-upload">
    <i class="fa fa-plus"></i>
</label>
<input name="steamidpost" type="hidden" value="123">
<input name="img" accept="image/*" type="file" id="file-upload" onchange="this.form.submit()">

还有php代码/upload-img.php

<?php
    include 'conn.php'; 
    session_start();

    if(isset($_POST['steamidpost'])) { 
        $id = $_POST['steamidpost'];
        $img = $_FILES['img'];
        if(isset($img['name'])) {
            $filename = $img['tmp_name'];
            $client_id = "MY SECRET ID";
            $handle = fopen($filename, "r");
            $data = fread($handle, filesize($filename));
            $pvars = array('image' => base64_encode($data));
            $timeout = 30;
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, 'https://api.imgur.com/3/image.json');
            curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
            curl_setopt($curl, CURLOPT_HTTPHEADER, array('Authorization: Client-ID '.$client_id));
            curl_setopt($curl, CURLOPT_POST, 1);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($curl, CURLOPT_POSTFIELDS, $pvars);
            $out = curl_exec($curl);
            curl_close($curl);
            $pms = json_decode($out, true);
            $url = $pms['data']['link'];
            if(isset($url)){
                //add to mysql code
            }
        }
    } 
    else {
        exit;
    }
?>

使用Ctrl + V时，将触发代码（用于Alert完成的测试），但是图像不会加载，仅页面被更新。怎么了？

错误：

[Mon Oct 01 21:28:01 2018] [warn] [client #] mod_fcgid: stderr: PHP Warning:  fopen(): Filename cannot be empty in ...
[Mon Oct 01 21:28:01 2018] [warn] [client #] mod_fcgid: stderr: PHP Warning:  fread() expects parameter 1 to be resource, boolean given in /upload-img.php ...
