我正在尝试在Yii2中添加一个REST api,供移动应用程序用来上传图像/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,但是由于某种原因fopen(“ php:// input”,“ r”);返回空流。我尝试了此示例http://www.php.net/m...put-method.php中给出的代码。
<?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方法也可以。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($putdata);
这是发送带有卷曲的PUT的方法:
curl -X PUT -d 'BLABLABLA' http://localhost/upload
然后在您的上传控制器中禁用csrf验证:
\yii::$app->request->enableCsrfValidation = false;
这是使用您的代码的示例上载控制器操作:
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
自版本2.0.10起,出现了一种内置机制,该机制使您可以将PUT与formData一起使用:https://www.yiiframework.com/doc/api/2.0/yii-web-multipartformdataparser
所以,首先您需要将解析器添加到配置文件中
return [
'components' => [
'request' => [
'parsers' => [
'multipart/form-data' => 'yii\web\MultipartFormDataParser'
],
],
// ...
],
// ...
];
下一步-执行getBodyParams
填充$ _FILES。应在之前请求任何文件时执行。
$restRequestData = Yii::$app->request->getBodyParams();
然后文件可以通过常规方法使用:
$file = UploadedFile::getInstancesByName('photo');
