PHP Lumen Laravel 解决validate方法自定义message无效的问题
/** * 由于 \Laravel\Lumen\Routing\ProvidesConvenienceMethods::validate 在验证不通过时, * 抛出 \Illuminate\Validation\ValidationException 异常时,message字段用的是固定的 => 'The given data was invalid.' * 且 \App\Exceptions\Handler::handler 只输出了异常的message字段, * 故自定义错误信息输出json时无法自定义 * * 这个方法在 validate 方法基础上修改,在验证不通过时抛出 \App\Exceptions\ValidationException , * message为错误堆栈中的第一条信息 * * demo * $params = $this->validateFilter($request, [ * 'id' => 'required|string' * ],[ * 'id.required' => 'id必须传' * ]); * * @param Request $request * @param array $rules * @param array $messages * @param array $customAttributes * @return array * @throws ValidationException */ public function validateMsg(Request $request, array $rules, array $messages = [], array $customAttributes = []) { $validator = $this->getValidationFactory()->make($request->all(), $rules, $messages, $customAttributes); if ($validator->fails()) { throw new ValidationException($validator->errors()->first()); } return $this->extractInputFromRules($request, $rules); }
/** * 调用 \App\Http\Controllers\Lap\BaseController::validateMsg 方法 * 并且只保留在$rules的key中存在的key,且过滤值为空字符串的数据 * @param Request $request * @param array $rules * @param array $messages * @param array $customAttributes * @return array * @throws ValidationException */ public function validateFilter(Request $request, array $rules, array $messages = [], array $customAttributes = []) { $this->validateMsg($request, $rules, $messages, $customAttributes); // 只保留在$rules的key中存在的key $rs = collect($request->all())->only(array_keys($rules))->toArray(); // 过滤值为空字符串的数据 return array_filter($rs, function ($item) { return $item !== ""; }); }
将这两个方法放到 \App\Http\Controllers\Controller 中,
或者自己新建一个BaseController extent \App\Http\Controllers\Controller
validateMsg 解决了错误信息不会放大异常的message字段的问题,
validateFilter 则是再进一步的包装,只返回验证规则配置的字段,且过滤值为空字符串的键值对
