大约一周以来，我一直在尝试解决 grails 4 应用程序的 prod 环境部署问题。当我通过 run-app 或 java -jar warfile.war 在本地运行我的应用程序时，我可以上传文件并在我的控制器中使用多部分内容。当我在 lightail ubuntu 20 服务器上部署运行应用程序时，由于某种原因，这些部件根本不存在。
UI表单代码：
<form id="file-form-${attrs.id}" enctype="multipart/form-data">
<input style="display:none;" id="${attrs.id}-file" type="file" name="file"
accept="image/png, image/jpeg, image/tiff"/>
</form>
UI ajax/js 代码：
var jForm = new FormData($('#file-form-'+id)[0]);
jForm.append("uploadField", $("#file-form-"+id).find('input[type="file"]').get(0).files[0]);
$.ajax({
url: '/files/uploadImage',
type: "POST",
data: jForm,
enctype: 'multipart/form-data',
processData: false,
cache: false,
contentType: false
}).done(function(data) {
// ...
}).fail(function(jqXHR, textStatus) {
// ...
});
控制器（请注意，这里所有的日志语句都是为了清楚起见，写起来很丑，一旦清楚就会被清理）：
def uploadImage() {
try {
log.debug("FilesController.uploadImage: IN for user ${session.user?.id}")
if (request instanceof MultipartHttpServletRequest) {
MultipartHttpServletRequest rqst = (MultipartHttpServletRequest) request
def myFile = params['uploadField']
params.each { k, v ->
log.debug("params k ${k}, v ${v}")
}
request.requestHeaders.each {k, v ->
log.debug("headers k ${k}, v ${v}")
}
def f
log.debug("parts " + request.parts?.size())
request.parts.each {part ->
log.debug("part ${part.name}")
if (f == null) f = part
}
log.debug("fileNames: ${request.getFileNames()}")
request.getFileNames().each { String fileName ->
log.debug("fileName: ${fileName}")
}
request.fileMap.each { String name, MultipartFile file ->
log.debug("Looping fileMap: name: ${name} and file ${file}")
if (f == null) f = file
}
log.debug('file: ' + f)
if (f == null) f = myFile
log.debug('file: ' + f)
log.debug("FilesController.uploadImage: calling imageService for user ${session.user?.id} ")
log.debug("imageService " + imageService)
File file = imageService.saveImage(f, session.user)
render text: file?.id
return
}
} catch (Exception e) {
log.error("FilesController.uploadImage: error ${e.getMessage()}")
}
render text: ''
}

在本地，那里有一个文件。
在我的 application.yml 中：
grails:
disableCommonsMultipart: false
web:
disable:
multipart: false
我不知道为什么在我的本地环境中接收到文件内容，但在生产环境中却没有。我无法想象 aws lightsail 会从 https 请求中剥离内容。在本地，我使用的是 http 而不是 https，不知道为什么这很重要。
有任何想法吗？提前感谢您提供的任何见解。
