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.

感谢您的帮助！

$curl = curl_init();
curl_setopt($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)).'.jpg';
        $photo_url = $temp_dir . $filename;
        imagejpeg($image, $photo_url);

        // upload image
        ...
    }
}

解决方案

发送

// 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); 

接收

/* 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);
