查询字符串参数中的斜线? [英] Slashes in a query string parameter?

问题描述

如何将文件路径作为查询字符串参数发送?

这是我的字符串参数:

<块引用>

//域/文档/PDF/1234.pdf

我已经试过了:

 [HttpPost][Route("documents/print/{filePath*}")]public string PrintDocuments([FromBody] string[] docs,string filePath){.....}

但这不起作用，我猜是因为参数开头的双斜杠.

有什么想法吗?

解决方案

如果，就像你说的，整个字符串是参数，而不是路由，你需要对它进行 URL 编码.无论如何，您应该始终这样做:

System.Net.WebUtility.UrlEncode(<你的字符串>);//%2F%2Fdomain%2Fdocuments%2Fpdf%2F1234.pdf

<块引用>

更新

由于这不起作用，我建议您对其进行 Base64 编码而不是 URL 编码:

var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(<你的字符串>);var encodingFilePath = System.Convert.ToBase64String(plainTextBytes);

..并在您的控制器中对其进行解码:

byte[] data = Convert.FromBase64String(filepath);字符串解码字符串 = Encoding.UTF8.GetString(data);

How can I send a file path as a query string parameter?

This is my string parameter:

//domain/documents/Pdf/1234.pdf

I have tried that:

    [HttpPost]
    [Route("documents/print/{filePath*}")]
    public string PrintDocuments([FromBody] string[] docs,string filePath)
    {
       .....
    }

But this is not working, I guess because of the double slashes in the beginning of the parameter.

Any idea?

解决方案

If, like you say, that entire string is the parameter, and not a route, you will need to URL encode it. You should always do this anyway:

System.Net.WebUtility.UrlEncode(<your string>);
// %2F%2Fdomain%2Fdocuments%2FPdf%2F1234.pdf

Update

Since that is not working, I would suggest you Base64 encode it instead of URL encode it:

var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(<your string>);
var encodedFilePath = System.Convert.ToBase64String(plainTextBytes);

..and in your controller decode it:

byte[] data = Convert.FromBase64String(filepath);
string decodedString = Encoding.UTF8.GetString(data);
