我正在构建一个基于REST的API,其中一个API具有以下请求
{
"categories_id" :"1",
"product_name" : "Pen",
"product_description" : "this is pen",
"tags" : "pen,write",
"image_count" : "4",
"skus":
{
"is_shippable":"n",
"actual_price":"100.55",
"selling_price":"200.45",
"quantity_type":"bucket",
"quantity_total":"10",
"bucket_value":"instock",
"sort_order":"1"
}
}
这些是我的验证规则
protected $rules = [
ValidatorInterface::RULE_CREATE => [
'users_id' => 'required',
'user_profiles_id' => 'required',
'categories_id' => 'required',
'product_name' => 'required|max:100',
'product_description' => 'required|max:1000',
'tags' => 'required',
'image_count'=>'required|integer',
'creation_mode'=>'required|integer',
'skus.is_shippable'=>'in:y,n',
'skus.actual_price'=>'regex:/^\s*(?=.*[1-9])\d*(?:\.\d{1,2})?\s*$/',
'skus.selling_price' => 'regex:/^\s*(?=.*[1-9])\d*(?:\.\d{1,2})?\s*$/',
'skus.quantity_type' => 'sometimes|required|in:finite,infinite,bucket',
'skus.quantity_total' => 'integer|required_if:skus.quantity_type,finite',
'skus.bucket_value'=>'in:instock,soldout,limited|required_if:skus.quantity_type,bucket',
'skus.sort_order'=> 'required|integer'
],
ValidatorInterface::RULE_UPDATE => [
]
];
上述请求已正确验证.但是skus可以在下面请求中包含多个实体
{
"categories_id" :"1",
"product_name" : "Pen",
"product_description" : "this is pen",
"tags" : "pen,write",
"image_count" : "4",
"skus":
[{
"is_shippable":"n",
"actual_price":"100.55",
"selling_price":"200.45",
"quantity_type":"bucket",
"quantity_total":"10",
"bucket_value":"instock",
"sort_order":"1"
},
{
"is_shippable":"n",
"actual_price":"100.55",
"selling_price":"200.45",
"quantity_type":"bucket",
"quantity_total":"10",
"bucket_value":"instock",
"sort_order":"1"
}]
}
如何验证是否存在多个嵌套实体？
您使用的是什么版本的Laravel？如果您使用的是Laravel 5.2,或者如果您不介意更新它,那么就有了开箱即用的解决方案.
数组验证
在Laravel 5.2中,验证数组表单输入字段要容易得多.例如,要验证给定数组输入字段中的每个电子邮件是否唯一,您可以执行以下操作:
$validator = Validator::make($request->all(), [
'person.*.email' => 'email|unique:users'
]);
同样,您可以在语言文件中指定验证消息时使用*字符,从而可以轻松地为基于数组的字段使用单个验证消息:
'custom' => [
'person.*.email' => [
'unique' => 'Each person must have a unique e-mail address',
]
],
Laravel新闻的另一个例子:
假装你有一个包含输入字段数组的表单,如下所示:
在Laravel 5.1中添加验证规则,它需要循环并单独添加规则.而不是必须做所有这些"Laravelized"到这个:
$v = Validator::make($request->all(), [ 'person.*.id' => 'exists:users.id', 'person.*.name' => 'required:string', ]);
因此,如果您不想使用Laravel 5.2,则必须手动执行,如果您更新到Laravel 5.2,则可以使用新的数组验证,它将是这样的:
protected $rules = [
ValidatorInterface::RULE_CREATE => [
'users_id' => 'required',
'user_profiles_id' => 'required',
'categories_id' => 'required',
'product_name' => 'required|max:100',
'product_description' => 'required|max:1000',
'tags' => 'required',
'image_count'=>'required|integer',
'creation_mode'=>'required|integer',
'skus.*.is_shippable'=>'in:y,n',
'skus.*.actual_price'=>'regex:/^\s*(?=.*[1-9])\d*(?:\.\d{1,2})?\s*$/',
'skus.*.selling_price' => 'regex:/^\s*(?=.*[1-9])\d*(?:\.\d{1,2})?\s*$/',
'skus.*.quantity_type' => 'sometimes|required|in:finite,infinite,bucket',
'skus.*.quantity_total' => 'integer|required_if:skus.quantity_type,finite',
'skus.*.bucket_value'=>'in:instock,soldout,limited|required_if:skus.quantity_type,bucket',
'skus.*.sort_order'=> 'required|integer'
],
ValidatorInterface::RULE_UPDATE => [
]
];
编辑
Ihmo添加这个额外验证逻辑的最好方法是扩展Validator类创建你的CustomValidator类,它可能有点矫枉过正,但是当Laravel 5.2发布时你可以删除你的CustomValidator并继续使用Laravel的5.2 Validator而不做任何修改你的代码.
怎么样？首先,我们在我们下面创建一个文件夹,app/我决定将此文件夹命名为Validator,您可以根据需要为其命名,只需记住更新以下类的命名空间即可.接下来,我们将在此文件夹CustomValidator.php,CustomValidatorServiceProvider.php和Factory.php中创建3个.php文件.
translator = $translator;
$this->customMessages = $messages;
$this->data = $this->parseData($data);
$this->customAttributes = $customAttributes;
// Explode the rules first so that the implicit ->each calls are made...
$rules = $this->explodeRules($rules);
$this->rules = array_merge((array) $this->rules, $rules);
}
/**
* Explode the rules into an array of rules.
*
* @param string|array $rules
* @return array
*/
protected function explodeRules($rules)
{
foreach ($rules as $key => $rule) {
if (Str::contains($key, '*')) {
$this->each($key, $rule);
unset($rules[$key]);
} else {
$rules[$key] = (is_string($rule)) ? explode('|', $rule) : $rule;
}
}
return $rules;
}
/**
* Define a set of rules that apply to each element in an array attribute.
*
* @param string $attribute
* @param string|array $rules
* @return void
*
* @throws \InvalidArgumentException
*/
public function each($attribute, $rules)
{
$data = Arr::dot($this->data);
foreach ($data as $key => $value) {
if (Str::startsWith($key, $attribute) || Str::is($attribute, $key)) {
foreach ((array) $rules as $ruleKey => $ruleValue) {
if (! is_string($ruleKey) || Str::endsWith($key, $ruleKey)) {
$this->mergeRules($key, $ruleValue);
}
}
}
}
}
/**
* Get the inline message for a rule if it exists.
*
* @param string $attribute
* @param string $lowerRule
* @param array $source
* @return string|null
*/
protected function getInlineMessage($attribute, $lowerRule, $source = null)
{
$source = $source ?: $this->customMessages;
$keys = ["{$attribute}.{$lowerRule}", $lowerRule];
// First we will check for a custom message for an attribute specific rule
// message for the fields, then we will check for a general custom line
// that is not attribute specific. If we find either we'll return it.
foreach ($keys as $key) {
foreach (array_keys($source) as $sourceKey) {
if (Str::is($sourceKey, $key)) {
return $source[$sourceKey];
}
}
}
}
/**
* Get the custom error message from translator.
*
* @param string $customKey
* @return string
*/
protected function getCustomMessageFromTranslator($customKey)
{
$shortKey = str_replace('validation.custom.', '', $customKey);
$customMessages = Arr::dot(
(array) $this->translator->trans('validation.custom')
);
foreach ($customMessages as $key => $message) {
if ($key === $shortKey || (Str::contains($key, ['*']) && Str::is($key, $shortKey))) {
return $message;
}
}
return $customKey;
}
}
此自定义验证器具有在Laravel 5.2上进行的所有更改,您可以在此处进行检查
现在我们有了一个新的CustomValidator类,我们必须找到一种使用它的方法,因为我们必须扩展ValidatorServiceProvider和Validator工厂.
app->singleton('validator', function ($app) {
$validator = new Factory($app['translator'], $app);
// The validation presence verifier is responsible for determining the existence
// of values in a given data collection, typically a relational database or
// other persistent data stores. And it is used to check for uniqueness.
if (isset($app['validation.presence'])) {
$validator->setPresenceVerifier($app['validation.presence']);
}
return $validator;
});
}
}
resolver)) {
return new Validator($this->translator, $data, $rules, $messages, $customAttributes);
}
return call_user_func($this->resolver, $this->translator, $data, $rules, $messages, $customAttributes);
}
}
现在我们已经扩展了验证以支持嵌套语法 sku.*.id
我们只需将Validator交换到CustomValidator,最后一步是更改文件config/app.php,在ServiceProviders数组中寻找ValidatorServiceProvider,只需注释该行并添加我们的扩展服务提供者,如下所示:
.... // Illuminate\Validation\ValidationServiceProvider::class, App\Validator\CustomValidatorServiceProvider::class, ....
我们评论它的原因是因为每当你将Laravel 5.1更新到5.2时你只想取消注释它,从列表中删除我们的CustomValidatorServiceProvider然后你删除我们的app/Validator文件夹,因为我们不再需要它了.
