extjs文件通过表单提交上传跨域 [英] extjs file uploads through form submit for cross domain

问题描述

我想从 extjs将文件上传到跨域服务器使用 form.submit()方法.当我调用 form.submit()时，请求将转到我宁静的Web服务，并且文件已成功上传.但是，该响应在浏览器中被以下消息阻止:阻止origi…host:1841框架访问跨域框架.

I would like to upload files to cross domain server from extjs using form.submit() method. When i call form.submit(), request is going to my restful web service and file is getting uploaded successfully. But the response is blocked at the browser with message: Blocked a frame with origi…host:1841" from accessing a cross-origin frame.

从较早的帖子和表单提交代码中，我发现 doSubmit()正在发送Ajax请求，而没有 cors:true 语句，这是由于跨域响应被阻止的缘故.

From older posts and form submit code, i found that doSubmit() is sending the Ajax request with out cors:true statement due to which cross domain response is blocked.

我曾想发送普通的Ajax请求，但不知道如何通过ajax请求读取文件数据并将其发送到服务器.

I thought of sending normal Ajax request but dont know how the file data can be read and send to server through ajax request.

在 php 的问题中仍然存在，以发送将文件数据作为 form.doSubmit()发送到服务器吗?有人可以帮我解决这个问题吗?

Is there anyway in php to send the file data to server as form.doSubmit()does? Can someone help me on this problem?

谢谢.

解决方案是: document.domain = document.domain是做什么的?和 http://codeengine.org/extjs-fileuplaod-cross-origin-frame/

推荐答案

Ajax调用不适用于下载，而我认为可以上传文件.

Ajax call does not work with downloading and i presume with uploading files.

您是否尝试在 doSubmit 之前设置此项:

Have you tried to set this before doSubmit:

Ext.Ajax.cors = true;
Ext.Ajax.useDefaultXhrHeader = false;
