有一个简单的上传示例演示应用程序，但它将上传存储在内存中，这对于大多数应用程序来说不是一个好主意。要将上传保存到临时文件，您当前必须执行以下操作（这是上传演示操作的修改版本）：

var fu = require("ringo/webapp/fileupload");

function upload(req) {
    if (fu.isFileUpload(req.contentType)) {
        var params = {};
        fu.parseFileUpload(req, params, req.charset, fu.TempFileFactory);
        return {
            status: 200,
            headers: {"Content-Type": "text/plain"},
            body: [params.file.name, " saved to ", params.file.tempfile]
        };
    }
    return Response.skin(module.resolve('skins/upload.txt'), {
        title: "File Upload"
    });
}

不幸的是，将上传保存到临时文件时存在一个错误，我刚刚修复了这个错误，所以您'必须手动使用当前的 git 快照或补丁文件 modules/ringo/webapp/fileupload.js：

我们还需要一些高级方法来为下一个版本执行此操作（例如设置 req.uploadTempDir 属性）。我将为此打开一个问题。

There's a simple upload example in the demo app, but it stores uploads in-memory which is not a good idea for most apps. To save uploads to a temporary file you'll currently have to do something like this (this is a modified version of the upload demo action):

var fu = require("ringo/webapp/fileupload");

function upload(req) {
    if (fu.isFileUpload(req.contentType)) {
        var params = {};
        fu.parseFileUpload(req, params, req.charset, fu.TempFileFactory);
        return {
            status: 200,
            headers: {"Content-Type": "text/plain"},
            body: [params.file.name, " saved to ", params.file.tempfile]
        };
    }
    return Response.skin(module.resolve('skins/upload.txt'), {
        title: "File Upload"
    });
}

Unfortunately, there was a bug with saving uploads to temp files that I just fixed, so you'll have to use a current git snapshot or patch file modules/ringo/webapp/fileupload.js manually:

http://github.com/ringo/ringojs/commit/1793a815a9ca3ffde4aa5a07c656456969b504f9

We also need some high level way of doing this for the next release (e.g. setting a req.uploadTempDir property). I'll open an issue for this.
