LDAP 与 objectCategory 查询问题

发布于 2024-10-17 17:11:16 字数 360 浏览 1 评论 0原文

我想创建 LDAP 查询来按名称、位置和型号过滤打印机

deSearch.Filter = String.Format("(&(&(&(&(objectCategory=printQueue)(printername={0}))(location={1}))(driverName={2})))", queueName, location, modelNumber);

我创建了此查询，但它运行不正确

第一个问题是如果其中一个条件为空或 null，则按所有搜索条件一起搜索
，我将其设置为 *得到所有结果。它正确吗？

欢迎所有想法

I want to create LDAP query to filter printers by name and location and model

deSearch.Filter = String.Format("(&(&(&(&(objectCategory=printQueue)(printername={0}))(location={1}))(driverName={2})))", queueName, location, modelNumber);

I create this but it didn't run correctly

The first problem is to search by all search criteria together
if one of criteria is empty or null ,I set it by * to get all results .Is it correct ?

All ideas are welcomed

您只需要一个 &操作员。它们是 LDAP 过滤器表达式中的 n 元运算符，而不是二进制运算符：

(&(objectCategory=printQueue)(printername={0})(location={1})(driverName={2}))

（RFC 2254 将 &（或 |）后面的内容定义为一组过滤器，而不是恰好两个过滤器。这是我能看到的唯一好的理由为什么他们选择那个可怕的前缀符号。）

我个人也会在这样的查询中提供“printQueue”作为参数。

'*' 将匹配任何属性值，但它要求该属性实际存在，即 objectClass具有这样的属性。

You only need one & operator. They are n-ary, not binary, operators in LDAP filter expressions:

(&(objectCategory=printQueue)(printername={0})(location={1})(driverName={2}))

(RFC 2254 defines what follows the & (or |) as a SET OF Filter, not as exactly two filters. This is about the only good reason I can see why they chose that ghastly prefix notation.)

I would personally supply 'printQueue' as an argument as well in a query like this.

'*' will match any attribute value, but it requires the attribute to be actually present, i.e. for the objectClass to have such an attribute.

根据 EJP 回复，我在这里创建了代码

 StringBuilder filter=new StringBuilder("(&(objectClass=printQueue)");
        if (!string.IsNullOrEmpty(queueName))
            filter.Append("(printerName=*"+queueName+"*)") ;

        if (!string.IsNullOrEmpty(location))

            filter.Append("(location=*" + location + "*)");

        if (!string.IsNullOrEmpty(modelNumber))

            filter.Append("(driverName=*" + modelNumber + "*)");

        filter.Append(")");

        deSearch.Filter = filter.ToString();

Accoroding to EJP reply I created the code for that here

 StringBuilder filter=new StringBuilder("(&(objectClass=printQueue)");
        if (!string.IsNullOrEmpty(queueName))
            filter.Append("(printerName=*"+queueName+"*)") ;

        if (!string.IsNullOrEmpty(location))

            filter.Append("(location=*" + location + "*)");

        if (!string.IsNullOrEmpty(modelNumber))

            filter.Append("(driverName=*" + modelNumber + "*)");

        filter.Append(")");

        deSearch.Filter = filter.ToString();
