我正在开发Zimbra Zimlet。 我正在从Javascript请求JSP(两者都属于同一个Zimlet)
var jspUrl = this.getResource("my.jsp");
var callback = new AjxCallback(this, this._rpcCallback, ["param1", "param2"]);
AjxRpc.invoke(null, jspUrl, null, callback, true);
_rpcCallback 功能
automator_HandlerObject.prototype._rpcCallback = function(p1, p2, response) {
if (response.success == true) {
appCtxt.getAppController().setStatusMsg(response.text);
} else {
console.log("response error");
}
}
我需要返回一些二进制文件以响应该请求。这是JSP代码
<%@ page import="java.io.FileInputStream" %>
<%@ page import="java.io.BufferedInputStream" %>
<%@ page import="java.io.File" %>
<%@ page import="java.io.IOException" %>
<%
ServletOutputStream outStream=response.getOutputStream();
File myfile = new File("/tmp/attachment.zip");
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;filename=attachment.zip");
response.setContentLength( (int) myfile.length( ) );
FileInputStream input = new FileInputStream(myfile);
BufferedInputStream buf = new BufferedInputStream(input);
int readBytes = 0;
while((readBytes = buf.read( )) != -1)
outStream.write(readBytes);
outStream.flush();
outStream.close();
buf.close();
%>
(“application / x-download”/“application / force-download”也使用FireFox和Chrome进行了测试)
我希望出现“保存文件”浏览器对话框。
我试过
document.write(response.text)
在 _rpcCallback 函数中,我可以看到相应的响应标头
HTTP/1.1 200 OK
Date: Fri, 03 May 2013 08:16:49 GMT
Expires: Thu, 01-Jan-1970 00:00:00 GMT
Content-Type: application/octet-stream
Content-Length: 20021
Set-Cookie: JSESSIONID=11ebfk145b34z;Path=/zimlet
Content-Disposition: attachment;filename=attachment.zip
以及二进制响应正文内容,但什么也没发生。
为了显示“下载文件”对话框而不是将文件打印为文本,必须包含哪些代码 _rpcCallback 功能?
使用Zimbra Desktop 7.2.2 GA进行测试
答案 0 :(得分:0)
感谢Julian找到了解决方案,这太简单了:
window.open(fileUrl);
