Grails 4，Ubuntu 20，嵌入式 Tomcat - 请求中没有多部分文件

Question

我已经尝试用 grails 4 应用程序的生产环境部署解决问题大约一周了。当我在本地运行我的应用程序时，通过运行-app 或 java -jar warfile.war，我能够上传文件并在我的控制器中提供多部分内容。当我在 lightsail ubuntu 20 服务器上部署运行应用程序时，由于某些原因，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>

UIajax/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，所有日志语句都在这里是为了清楚起见，它写得非常丑陋，一旦清晰起来就会被清理）：

    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:

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，但在生产环境中却接收不到。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，不确定为什么会很重要。

有什么想法吗？预先感谢您提供的任何见解。

最终，问题证明是ssl相关的。我使用的 grails 版本是 4.0.3。对于该版本，嵌入的 tomcat 依赖项是 org.springframework.boo:spring-boot-starter-tomcat 并且被拉取的版本是 2.1.13.RELEASE。 spring 启动库利用了 tomcat 版本 9.0.31。找到这篇文章后，只需指定一个 tomcat 版本即可解决在 ssl 上解析多部分文件的问题：

compile "org.apache.tomcat.embed:tomcat-embed-websocket:9.0.33"
compile "org.apache.tomcat.embed:tomcat-embed-core:9.0.33"
compile "org.apache.tomcat.embed:tomcat-embed-el:9.0.33"
compile "org.apache.tomcat:tomcat-juli:9.0.33"
compile "org.apache.tomcat:tomcat-annotations-api:9.0.33"

我希望它能为其他人节省一些时间。和平
