Question

我正在执行Meteor.call('searchDatabase', keys...)，只要用户提交搜索就会执行该keys。我目前正在传递一系列名为check(keys, ?)的提交词。但是，我不知道如何在服务器端执行必要的keys.forEach(function(element) { check(element, String)}。我原本以为我可以Did not check() all arguments，但我仍然会收到<?php $i=0; $count=0; foreach ($_FILES['file']['name'] as $filename) { $upload_dir = $_SERVER['DOCUMENT_ROOT'] . "/upload/"; if(file_exists($upload_dir.$filename)) { echo "That File Already Exist"; break; } else { $tmp = $_FILES['file']['tmp_name'][$count]; $count++; $i++; $target = $upload_dir.basename($filename); if (is_dir($upload_dir) && is_writable($upload_dir)) { move_uploaded_file($tmp,$target); $sql = "UPDATE `fleet` SET `image$i`='$target',`image_name$i`='$filename' WHERE id='$id' "; if (!mysqli_query($con,$sql)) { die('Error: ' . mysqli_error($con)); } } else { echo 'Upload directory is not writable, or does not exist.'; } }错误。我应该在Meteor方法调用中将提交的搜索作为其原始字符串传递，然后在服务器上将其分解吗？或者有办法检查键是否为数组？

Answer 1

如果keys是一个字符串数组，您可以这样做：

check(keys, [String]);

您的方法看起来像：

Meteor.methods({
  searchDatabase: function(keys) {
    check(keys, [String]);
    // add other method code here
  }
})

如下所示：https://forums.meteor.com/t/check-object-in-an-array/3355

var subscriptions = [
  {/* ... */},
  {/* ... */},
  {/* ... */}
];

check(subscriptions, Match.Where(function(subscriptions){
  _.each(subscriptions, function (doc) {
    /* do your checks and return false if there is a problem */
  });
  // return true if there is no problem
  return true;
}));

Answer 3

如果您使用simple-schema，则应尝试以下方式：

check( keys, [ mySchema ] );

Answer 4

万一它对其他人有帮助，我将Meteor forums的答案改写为使用箭头函数，并避免使用下划线和重复声明：

check(subscriptions, Match.Where((myArray) => {
    myArray.forEach((myObject) => {
        /* do your checks and return false if there is a problem */
    });
    // return true if there is no problem
    return true;
}));

这将检查对象数组。

Meteor.call检查数组参数
