Question

是否可以在id代码的glink属性中添加多个值？

我希望得到一个网址：/place/view/home/7?（/＆lt; controller＆gt; /＆lt; action＆gt; /＆lt; name＆gt; /＆lt; id＆gt;？params）

是否可以使用glink代码？

Answer 1

如果我正确理解您正在寻找的是params选项，

<g:link controller="cname" action="act" id="1" params="[sort: 'title']" />

Answer 2

我在Grails v2.4.3中使用以下解决方案：

在UrlMappings.groovy中，我补充道：

static mappings = {
    ...
    name dualId: "/$controller/$action/$id/$id2?(.$format)?" {}

    /* Usage:
     *  <g:link mapping="dualId" action="myMethod" params='[id2: "${id2Value}"]'>
     *    Accept id AND id2
     *  </g:link>

     *  Generates following link in the UI: 
     *    <a href="/myController/myMethod/142/387">Accept id AND id2</a>
     *  SPECIAL NOTE: params='[id2: "${id2Value}"]' works.
     *    using: params="[id2: '${id2Value}']" DOES NOT WORK!
     */
    ...
}

根据您的要求，＆＃34; / place / view / home / 7？（/＆lt; controller＆gt; /＆lt; action＆gt; /＆lt; name＆gt; /＆lt; id＆gt;？params）＆＃34;，您可以使用：

static mappings = {
    ...
    name placeViewHome: "/$controller/$action/$name/$id?" {}

    /* Usage:
     *  <g:link mapping="placeViewHome" action="myAction" params='[name: "${nameValue}", q: "str"]'>
     *    Accept name AND id
     *  </g:link>

     *  Should generate the following link in the UI: 
     *    <a href="/myController/myMethod/myName/387?q=str">Accept name AND id</a>
     *  I didn't try it, but you should be able to add in other params and I would expect them to appear after the question mark as usual.
     */
    ...
}

注意：在g：链接中，引号的顺序很重要，单引号内的双引号有效，但不是相反。
