使用gwt的RequestBuilder下载文件 [英] file download using RequestBuilder of gwt

问题描述

我需要实现文件下载。我不想要任何服务器端的文件URL直接下载。我创建了一个servlet，它将打开该文件并将其写入到响应流中。现在来到gwt我有onResponseReceived （请求请求，响应响应）将在接收到响应时调用。现在如何进一步？ 。我需要的操作是，文件流应该被下载到客户端计算机。

推荐答案

你可以使用任何_blank，_parent，_top，_self

You could use any of _blank, _parent, _top, _self

• _ blank属性导致
  atarget超链接在
  a中打开新的


• _ top属性导致target
  的超链接显示在所有当前定义的
  框架集的
  顶层。


• _ parent属性导致
  目标的超链接，以在当前
  框架集的整个区域中显示
  。


• _ self属性导致目标
  的超链接在
  当前框架中打开。

• "_blank" attribute causes the "target" of the hyperlink to open in a new
• "_top" attribute causes the "target" of the hyperlink to display at the top level of all currently defined framesets.
• "_parent" attribute causes the "target" of the hyperlink to display in the entire area of the current frameset.
• "_self" attribute causes the "target" of the hyperlink to open in the current frame.
