使用API​​ PUT请求上传文件 [英] Upload a file using an API PUT request

问题描述

我在PHP中构建一个API。其中一种方法是place.new（PUT请求）。它期望几个字符串字段，它也期望一个图像。但我不能得到它的工作。使用POST请求很容易，但我不知道如何做一个PUT和如何获取服务器上的数据。

感谢您的帮助！

测试CURL代码

  $ curl = curl_init（）; 
 curl_setopt（$ curl，CURLOPT_CONNECTTIMEOUT，2）; 
 curl_setopt（$ curl，CURLOPT_HEADER，false）; 
 curl_setopt（$ curl，CURLOPT_RETURNTRANSFER，1）; 
 curl_setopt（$ curl，CURLOPT_BINARYTRANSFER，1）; 
 curl_setopt（$ curl，CURLOPT_URL，$ this-> url）; 
 
 curl_setopt（$ curl，CURLOPT_PUT，1）; 
 curl_setopt（$ curl，CURLOPT_INFILE，$ image）; 
 curl_setopt（$ curl，CURLOPT_INFILESIZE，filesize（$ image））; 
 
 $ this-> result = curl_exec（$ curl）; 
 curl_close（$ curl）; 
  

服务器代码

  if（$ im_s = file_get_contents（'php：// input'））
 {
 $ image = imagecreatefromstring（$ im_s）; 
 
 if（$ image！=''）
 {
 $ filename = sha1（$ title.rand（11111，99999））。 
 $ photo_url = $ temp_dir。 $ filename; 
 imagejpeg（$ image，$ photo_url）; 
 
 //上传图片
 ... 
} 
} 
  

$ b b

解决方案

发送

  /正确：/ Users / john / Sites / .... 
 //不正确：http：// localhost / ... 
 $ image = fopen（$ file_on_dir_not_url，rb）; 
 
 $ curl = curl_init（）; 
 curl_setopt（$ curl，CURLOPT_CONNECTTIMEOUT，2）; 
 curl_setopt（$ curl，CURLOPT_HEADER，false）; 
 curl_setopt（$ curl，CURLOPT_RETURNTRANSFER，1）; 
 curl_setopt（$ curl，CURLOPT_BINARYTRANSFER，1）; 
 curl_setopt（$ curl，CURLOPT_URL，$ url）; 
 
 curl_setopt（$ curl，CURLOPT_PUT，1）; 
 curl_setopt（$ curl，CURLOPT_INFILE，$ image）; 
 curl_setopt（$ curl，CURLOPT_INFILESIZE，filesize（$ file_on_dir_not_url））; 
 
 $ result = curl_exec（$ curl）; 
 curl_close（$ curl）; 
  

接收

  / *添加以澄清，每个注释* / 
 $ putdata = fopen（php：// input，r）; 
 
 / *打开要写入的文件* / 
 $ fp = fopen（$ photo_url，w）; 
 
 / *一次读取数据1 KB 
并写入文件* / 
 while（$ data = fread（$ putdata，1024））
 {
 fwrite（$ fp，$ data）; 
} 
 
 / *关闭流* / 
 fclose（$ fp）; 
 fclose（$ putdata）;你读过  

/php.net/manual/en/features.file-upload.put-method.php\">http://php.net/manual/en/features.file-upload.put-method.php ？ Script PUT /put.php 所有设置？

此外， $ image - 它需要是一个文件处理程序，而不是文件名。

Ps。使用 file_get_contents 将尝试将服务器上的任何PUT加载到内存中。不是一个好主意。请参阅链接的手册页。

I'm building an API in PHP. One of the methods is place.new (PUT request). It expects several string fields, and it also expects an image. However I can't get it working. With a POST request it was easy, but I'm not sure how to do it with a PUT and how to get the data on the server.

thanks for the help!

Test CURL code

$curl = curl_init();
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($curl, CURLOPT_URL, $this->url);

curl_setopt($curl, CURLOPT_PUT, 1);
curl_setopt($curl, CURLOPT_INFILE, $image);
curl_setopt($curl, CURLOPT_INFILESIZE, filesize($image));

$this->result = curl_exec($curl);
curl_close($curl); 

Server code

if ( $im_s = file_get_contents('php://input') )
{
    $image = imagecreatefromstring($im_s);

    if ( $image != '' )
    {
        $filename = sha1($title.rand(11111, 99999)).'.jpg';
        $photo_url = $temp_dir . $filename;
        imagejpeg($image, $photo_url);

        // upload image
        ...
    }
}

Solution

send

// Correct: /Users/john/Sites/....
// Incorrect: http://localhost/...
$image = fopen($file_on_dir_not_url, "rb");

$curl = curl_init();
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($curl, CURLOPT_URL, $url);

curl_setopt($curl, CURLOPT_PUT, 1);
curl_setopt($curl, CURLOPT_INFILE, $image);
curl_setopt($curl, CURLOPT_INFILESIZE, filesize($file_on_dir_not_url));

$result = curl_exec($curl);
curl_close($curl); 

receive

/* Added to clarify, per comments */
$putdata = fopen("php://input", "r");

/* Open a file for writing */
$fp = fopen($photo_url, "w");

/* Read the data 1 KB at a time
    and write to the file */
while ($data = fread($putdata, 1024))
{
    fwrite($fp, $data);
}

/* Close the streams */
fclose($fp);
fclose($putdata);

解决方案

Did you read http://php.net/manual/en/features.file-upload.put-method.php ? Script PUT /put.php all set up?

Also, what is $image -- it needs to be a file handler, not a file name.

Ps. Using file_get_contents will try to load whatever is PUT on the server into memory. Not a good idea. See the linked manual page.
