yii2使用PUT上传REST Api文件 - yii2 REST Api file upload using PUT

yii2 REST Api file upload using PUT

本文关键字：Api 文件 REST 上传使用 PUT yii2 | 更新日期: 2023-09-27

我试图在Yii2中添加一个REST api，由移动应用程序用于上传图像/音频文件。我试图使用PUT方法从http表单数据中获取图像/文件数据，但由于某种原因，fopen("php://输入"，"r");返回空流。我尝试了这个示例中的代码http://www.php.net/m...put-method.php.

<?php
/* PUT data comes in on the stdin stream */
$putdata = fopen("php://input", "r");
/* Open a file for writing */
$fp = fopen("myputfile.ext", "w");
/* Read the data 1 KB at a time
   and write to the file */
while ($data = fread($putdata, 1024))
  fwrite($fp, $data);
/* Close the streams */
fclose($fp);
fclose($putdata);
?>

同时，使用POST方法可以工作。对POST

使用以下代码

$putdata = fopen($_FILES['photo']['tmp_name'], "r");
        $filename = $this->documentPath.uniqid().'.jpg';
        /* Open a file for writing */
        $fp = fopen($filename, "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);

自2.0.10版本以来，出现了一种内置机制，允许您对formData使用PUT: https://www.yiiframework.com/doc/api/2.0/yii-web-multipartformdataparser

所以，首先你需要添加解析器到配置文件

return [
    'components' => [
        'request' => [
            'parsers' => [
                'multipart/form-data' => 'yii'web'MultipartFormDataParser'
            ],
        ],
        // ...
    ],
    // ...
];

下一步-执行getBodyParams填充$_FILES。这应该在请求任何文件之前执行。

$restRequestData = Yii::$app->request->getBodyParams();

然后文件可以通过一般方法获得:

$file = UploadedFile::getInstancesByName('photo');

如何使用curl发送PUT:

curl -X PUT -d 'BLABLABLA' http://localhost/upload

然后在上载控制器中禁用csrf验证:

'yii::$app->request->enableCsrfValidation = false;

下面是一个使用代码上传控制器动作的示例:

public function actionIndex()
{
   'yii::$app->request->enableCsrfValidation = false;
   $putdata = fopen("php://input", "r");
   // make sure that you have /web/upload directory (writeable) 
   // for this to work
   $path = 'yii::getAlias('@webroot')."/upload/myputfile.ext";
   $fp = fopen($path, "w");
   while ($data = fread($putdata, 1024))
      fwrite($fp, $data);
   /* Close the streams */
   fclose($fp);
   fclose($putdata);

}

检查上传:

$ cat /path/to/webroot/upload/myputfile.ext
BLABLABLA
