使用JSON + AJAX上传文件？ [英] file upload with JSON+AJAX?

问题描述

我想转换一个目前使用传统

CGI序列的表单（即与表单相关的操作发送一个POST

请求服务器端CGI脚本）使用AJAX向远程Web服务发送

a JSON编码的请求。


绊脚石阻止我遇到的是

中的一个输入表单是文件上传元素，我不知道如何将
包括在内来自JSON有效负载中指定文件的数据。

有办法吗？


TIA！

编号XHR不允许本地文件访问，

它在本地运行时执行。

因此，对于文件上传，您必须使用传统表单。

正确。

No. XHR不允许本地文件访问，

它在本地运行时执行。

在通过HTTP运行时也会执行，并且授予所需的权限，

或用完沙箱时。

I would like to convert a form that currently uses the traditional
CGI sequence (i.e. the action associated with the form sends a POST
request to a server-side CGI script) to one that uses AJAX to send
a JSON-encoded request to a remote web service.

The stumbling block I''m running into is that one of the inputs in
the form is a file upload element, and I can''t figure out how to
include the data from the specified file in the JSON payload. Is
there a way to do this?

TIA!

No. XHR doesn''t allow local file access, so for the file upload you
have to use traditional forms.

No. XHR doesn''t allow local file access,

It does when running locally.

Correct.

No. XHR doesn''t allow local file access,

It does when running locally.

It also does when running via HTTP, and the required privileges are granted,
or when running out of the sandbox.
