我正在尝试上传文件并将其存储在文件中。这是 GSP 中的代码:
<g:form method="post" enctype="multipart/form-data" action="update">
<input type="file" name="cv" id="cv"/>
<g:actionSubmit action="upload" name="upload" value="Upload" />
</g:form>
在控制器中:
def upload(){
def f = request.getFile('cv')
InputStream file = f.inputStream
byte[] bytes = file.bytes
println('bytes: '+bytes)
}
正如我在标题中所说,我在这里遇到了例外。有什么帮助吗?谢谢。
编辑(完整堆栈跟踪,根据要求):

问题是您的请求没有被视为 MultiPartRequest。做这样的事情:
MultipartRequest multipartRequest = request as MultipartRequest
if(multipartRequest){
MultipartFile attachmentFile = multipartRequest.getFile("attachment_file".toString())
if (attachmentFile) {
-- copy it ---
}
}
