使用 API PUT 请求上传文件

发布于 2024-11-08 20:04:28 字数 1969 浏览 0 评论 0原文

我正在用 PHP 构建一个 API。其中一种方法是 place.new(PUT 请求)。它需要几个字符串字段,并且还需要一个图像。但是我无法让它工作。使用 POST 请求很容易,但我不确定如何使用 PUT 来执行此操作以及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)).'.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);

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!

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($curl, CURLOPT_PUT, 1);
curl_setopt($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);

您是否阅读过http://php.net/manual/en/features.file-upload .put-method.php脚本 PUT /put.php 全部设置好了吗?

另外,什么是 $image ——它需要是一个文件处理程序,而不是文件名。

诗。使用 file_get_contents 将尝试将服务器上放置的所有内容加载到内存中。这不是一个好主意。请参阅链接的手册页。

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.

PHP 不会在 PUT 请求中填充表单数据(无论是在 PATCH 中)。

只需安装 https://pecl.php.net/package/apfdPATCHPUT 请求将包含 $_POST$_FILES,就像 GET一样POST 请求。

在 Docker 中它将是:

RUN pecl install --force apfd && rm -rf /tmp/pear && docker-php-ext-enable apfd

PHP doesn't populate form data in PUT requests (either in PATCH).

Just install https://pecl.php.net/package/apfd and PATCH and PUT request will have $_POST and $_FILES as if were GET or POST requests.

In Docker it will be:

RUN pecl install --force apfd && rm -rf /tmp/pear && docker-php-ext-enable apfd
