使用asp.net mvc在Dropbox中下载文件 [英] Download a file in Dropbox using asp.net mvc

问题描述

我正在使用asp.net mvc 4和dropbox-api从我的保管箱帐户下载文件.我已经在项目中成功安装了api，并且正在关注 本教程 了解功能，但是如果运行我会收到错误消息，

I'm using asp.net mvc 4 and dropbox-api to download a file from my dropbox account. I've successfully installed the api in my project and I'm following this tutorial to understand the functionalities but I'm getting an error if I run,

指定的参数超出有效值范围. 参数名称:路径

Specified argument was out of the range of valid values. Parameter name: path

这是我的密码，

    public async Task<ActionResult> DropDls()
    {
        var dbx = new DropboxClient("MY-TOKEN");
        string folder = "My Folder";
        string file = "My File.rar";

        using (var response = await dbx.Files.DownloadAsync(folder + "/" + file))
        {
            await response.GetContentAsStringAsync();
        }

        return View();
    }

我不喜欢api相关的作品，因此无法弄清楚这里有什么问题.但是我需要做到这一点.如果能得到专家的帮助，我将不胜感激.谢谢.

I'm noob to api related works, so can't figure it out what is wrong in here. But I need this to be done. I'll appreciate if I get some help from experts. Thanks.

推荐答案

Dropbox API的非根路径应以"/"开头.您的代码是:

Non-root paths for the Dropbox API should start with "/". Your code is:

    string folder = "My Folder";
    string file = "My File.rar";

...

    using (var response = await dbx.Files.DownloadAsync(folder + "/" + file))

这将导致路径"My Folder/My File.rar"，但实际上应为"/My Folder/My File.rar".因此，相反，您可能需要这样的代码:

That will result in a path "My Folder/My File.rar", but it should actually be "/My Folder/My File.rar". So, instead, you probably want code like this instead:

    using (var response = await dbx.Files.DownloadAsync("/" + folder + "/" + file))
