Question

我需要通过PUT方法接收图像发送。因此，我正在编写脚本来测试它。我想接收并使用相同的脚本发送它。我该如何实现呢？以下变体没有任何回声和字符串关于祝贺http方法发送正常。

<?php 
//if they DID upload a file...
var_dump(file_get_contents("php://input"));
if($_FILES['photo']['tmp_name'])
{
    echo $_FILES['photo']['error'];
    if($_FILES['photo']['error']==0)
    {
        //now is the time to modify the future file name and validate the file
        $new_file_name = strtolower($_FILES['photo']['tmp_name']); //rename file
        $message = 'Congratulations!!!!!!!.';
            //move it to where we want it to be
            move_uploaded_file($_FILES['photo']['tmp_name'], 'url.../1.jpg');

            echo'Congratulations!  Your file was accepted.';
            $image = fopen('url.../1.jpg', "rb");
            var_dump($image);
            $ch = curl_init();


            /* Set cURL options. */
            curl_setopt($ch, CURLOPT_URL, "http://url.../upload.php");
            curl_setopt($ch, CURLOPT_PUT, true);
            curl_setopt($ch, CURLOPT_INFILE, $image);
            curl_setopt($ch, CURLOPT_INFILESIZE, strlen($image));

            /* Execute the PUT and clean up */
            $result = curl_exec($ch);
            fclose($image);             //recommended to close the fileshandler after action
            curl_close($ch);
    }
    //if there is an error...
    else
    {
        //set that to be the returned message
        $message = 'Ooops!  Your upload triggered the following error:  '.$_FILES['photo']['error'];
    }
}
else
{
    echo"WORKS";
}

将图像发送回浏览器的最简单方法是使用网址。

处理图片
将图像保存在服务器上的某个位置
将网址发回浏览器。
在浏览器中使用标记并显示图像。

<?PHP 
  $imgFile="";
  if($_FILES['photo']['tmp_name'])
  {
      ///Your existing code
      $imgFile="http://" . $_SERVER['HTTP_HOST'] .'/Your image url here'; 
      //Ex:\\ http://yourserver.com/images/1.jpg - 
      //you can take this from your move_upload_file
  }   

?>
<img src="<?PHP echo $imgFile; ?>" />

即使是安静的服务，您也可以使用json或xml将图片网址发回。 PUT不是一个好主意，除非你因某种原因需要发回图像数据。你应该重新考虑一下你的逻辑吗？

错误是： strlen($image) strlen如果错误，必须是文件大小，并且在我的网址中我有www。这不是我的帖子，但它是错误的。更有经验的程序员帮助了我。 r.php读取流：

$ res = file_get_contents（“php：// input”）;

$file = fopen('1.txt', "w");
fputs($file, $res);
fclose($file);

var_dump($res);

s.php获取流和init r.php

$image = fopen('/var/www/testfiles/1.jpg', "rb");
var_dump($image);
$ch = curl_init();


/* Set cURL options. */

    curl_setopt($ch, CURLOPT_URL, "http://url withot www/r.php");
    curl_setopt($ch, CURLOPT_PUT, true);
    curl_setopt($ch, CURLOPT_INFILE, $image);
    curl_setopt($ch, CURLOPT_INFILESIZE, filesize('/var/www/testfiles/1.jpg'));

    /* Execute the PUT and clean up */
    $result = curl_exec($ch);
    fclose($image);             //recommended to close the fileshandler after action
    curl_close($ch);

    die("OK");
