如何使用尊重验证库验证 $_FILES

How to validate $_FILES using Respect Validation library

我正在使用 Respect Validation 来尝试验证文件上传。我遇到的问题是验证总是失败,即使已上传正确的图片。

这是我的代码:

public function updateProfilePicture(Request $request, Response $response, $args = []) {

    $files = $request->getUploadedFiles();

    if(empty($files['image'])) {
        throw new AppException('Invalid image');
    }

    // Validate image
    $validator = v::key('image', v::image());

    try {
        $validator->assert($files);
        // $validator->assert($_FILES);
    } catch(NestedValidationException $e) {
        throw new AppException($e->getMessage());
    }
}

我得到的错误是:

{
  "status": false,
  "data": null,
  "message": "All of the required rules must pass for { \"image\": { \"name\": \"twitter.png\", \"type\": \"image/png\", \"tmp_name\": \"/private/var/folders/ry/kgy3g6v96s71jg3htn6r5rt80000gn/T/php7x3P6w\", \"error\": 0, \"size\": 210955 } }"
}

正如评论中所建议的那样,我尝试使用 $validator->assert($files['image']);。这不起作用并产生以下错误:

{
  "status": false,
  "data": null,
  "message": "All of the required rules must pass for `[object] (Slim\Http\UploadedFile: { \"file\": \"/private/var/folders/ry/kgy3g6v96s71jg3htn6r5rt80000gn/T/phppJn1Uw\" })`"
}

$files变量包含:

array(1) {
  ["image"]=>
  object(Slim\Http\UploadedFile)#120 (8) {
    ["file"]=>
    string(66) "/private/var/folders/ry/kgy3g6v96s71jg3htn6r5rt80000gn/T/php8sPpkD"
    ["name":protected]=>
    string(11) "twitter.png"
    ["type":protected]=>
    string(9) "image/png"
    ["size":protected]=>
    int(210955)
    ["error":protected]=>
    int(0)
    ["sapi":protected]=>
    bool(true)
    ["stream":protected]=>
    NULL
    ["moved":protected]=>
    bool(false)
  }
}

并且$_FILES包含:

array(1) {
  ["image"]=>
  array(5) {
    ["name"]=>
    string(11) "twitter.png"
    ["type"]=>
    string(9) "image/png"
    ["tmp_name"]=>
    string(66) "/private/var/folders/ry/kgy3g6v96s71jg3htn6r5rt80000gn/T/phpm0Gv35"
    ["error"]=>
    int(0)
    ["size"]=>
    int(210955)
  }
}

按照评论中的建议,我已经尝试 $validator->assert($_FILES['image']['tmp_name']); 并收到以下错误:

{
  "status": false,
  "data": null,
  "message": "All of the required rules must pass for \"/private/var/folders/ry/kgy3g6v96s71jg3htn6r5rt80000gn/T/php8E5apg\""
}

我已经尝试 Google 看看其他人是怎么做的,但找不到任何有用的东西。

尝试这样做:

var_dump(v::image()->validate($_FILES['image']['tmp_name‌​']‌​));
