我需要以我在文本和在线中查看过的PDF上载grails。这是我到目前为止在 Controller 中拥有的

def upload = {
def f = request.getFile('myFile')
if(!f.empty) {
f.transferTo( new File('/some/local/dir/myfile.txt') )
response.sendError(200,'Done');
} else {
flash.message = 'file cannot be empty'
render(view:'uploadForm')
}
}

在 View 中,我在_forms View 中
    <g: uploadForm action="upload">
<input type="file" name="myFile"/>
<input type= "submit" value="Upload"/>
</g: uploadForm>

当我转到创建页面时,出现错误。

我得到这个错误
Grails标记[g:]未关闭。 Stacktrace如下:
Message: Error processing GroovyPageView: Grails tag [g:] was not closed
Line | Method
->> 461 | doFilter in \grails-app\views\report\create.gsp

Caused by GrailsTagException: Grails tag [g:] was not closed
->> 36 | doCall in C:/Users/Owner/Desktop/grails-app/views/report/create.gsp

关于如何清除错误的任何建议?当我删除_forms View 中的附加内容时,错误就消失了。我看不到未关闭的标签

要求的完整gsp
<div class="fieldcontain ${hasErrors(bean: reportInstance, field: 'location', 'error')} required">
<label for="location">
<g:message code="report.location.label" default="Location" />
<span class="required-indicator">*</span>
</label>
<g:select id="location" name="location.id" from="${lc.Location.list()}" optionKey="id" required="" value="${reportInstance?.location?.id}" class="many-to-one"/>
</div>

<div class="fieldcontain ${hasErrors(bean: reportInstance, field: 'published', 'error')} required">
<label for="published">
<g:message code="report.published.label" default="Published" />
<span class="required-indicator">*</span>
</label>
<g:datePicker name="published" precision="day" value="${reportInstance?.published}" />
</div>

<div class="fieldcontain ${hasErrors(bean: reportInstance, field: 'title', 'error')} ">
<label for="title">
<g:message code="report.title.label" default="Title" />

</label>
<g:textField name="title" value="${reportInstance?.title}"/>
</div>

<div class="fieldcontain ${hasErrors(bean: reportInstance, field: 'myFile', 'error')} ">
<label for="myFile">
<g:uploadForm action="upload"/>
<input type="file" name="myFile"/>
<input type= "submit" value="Upload"/>
</g:uploadForm>

</label>
</div>

最佳答案

从中删除/

<g:uploadForm action="upload"/>

这应该是
<g:uploadForm action="upload">
....
</g:uploadForm>
