grails - 从URL下载内容而不提示在Grails中进行身份验证

Question

我正在使用Grails编程的Web应用程序。我有一个页面用于显示某些报告，这些报告可以包含附件。附件存储在documentum中，当前，当用户单击它时，它只是到documentum中存储附件的位置的链接，并提示用户输入其凭据。我的应用程序的文档凭证存储在配置文件中，因此我想使用这些凭证，而不是强制用户输入自己的凭证。我正在使用RESTful服务来检索链接，但是我试图找到一种使用链接直接下载到用户计算机的方法。

private def getFileInfo(def id, def subject) {
  // product show view needs the following four lists to display the document information correctly
  def ATRReportInstance = ATRReport.findByTrackingNumber(id)
  def linkList = []
  def nameList = []
  def formatList = []
  def idList = []
  // open up a connection to the documentum server
  def doc = connectToDocumentum()

  if (!doc) return
  def rest = doc.rest
  def response = doc.response
  if (response.status == 200) {
    // retrieve the folder for this product (the name of this folder is the product's ID)
    def rObjectId = rest.get(documentumServer + "/repositories/" + documentumfilestore + "?dql=select r_object_id from dm_folder where any r_folder_path='" + atrreportfolderpath + "/" + id + "'") {
      auth authuser, authpass
    }
    // get the folder's ID from the folder object retrieved above
    def folderObjectID
    rObjectId.json.entries.each {
      entry - >
        folderObjectID = entry.content.properties.r_object_id
    }
    // get all of the documents in the product's MSDS folder using the folder ID retrieved above
    def resp = rest.get(documentumServer + "/repositories/" + documentumfilestore + "?dql=select r_object_id, object_name, a_content_type, subject from cbs_document where any i_folder_id= '" + folderObjectID + "'") {
      auth authuser, authpass
    }
    // cycle through the documents above to populate the four MSDS document information lists
    def x = 0
    resp.json.entries.each {
      entry - >
        if (entry.content.properties.subject == subject) {
          // get the document's content object from the document's ID
          def content = rest.get(documentumServer + "/repositories/" + documentumfilestore + "/objects/" + entry.content.properties.r_object_id + "/contents/content" + "?media-url-policy=local") {
            auth authuser, authpass
          }
          if (entry.content.properties.r_object_id != null && ATRReportInstance.inactiveFiles != null && ATRReportInstance.inactiveFiles.contains(entry.content.properties.r_object_id.toString())) {} else {
            linkList[x] = getLink(content.json.links, "enclosure")
            if (linkList[x].contains("format=msg"))
              linkList[x] = linkList[x].toString().substring(0, linkList[x].toString().indexOf("content-media")) + "content-media.msg"

            formatList[x] = entry.content.properties.a_content_type
            nameList[x] = entry.content.properties.object_name
            idList[x] = entry.content.properties.r_object_id
            x++
          }
        }
    }
    return [linkList: linkList, nameList: nameList, formatList: formatList, idList: idList]
  } else {
    // return null if documentum is unavailable
    flash.message = message(code: 'error.documentum.unavailable')
    return null
  }
}

我正在考虑编写另一个可以接受URL并将函数下载到用户的功能，但是我无法弄清楚如何在Grails中检索该文档。

如果要绕过登录，则可以设置SSO解决方案(需要DCTM进行一些工作)或按照您的建议执行功能。但是，在执行此操作时应考虑许可条款。
