.NET MVC从JSON Uint8Array反序列化字节数组 [英] .NET MVC deserialize byte array from JSON Uint8Array

问题描述

我正在使用js-scrypt（ https://github.com/tonyg/js-scrypt ）在我的客户端Web应用程序上，在将密码发布到我的服务器端.NET MVC应用程序之前对哈希密码进行哈希和盐密封再次进行哈希和盐析。此JavaScript库将字节数组实现为JavaScript Uint8Arrays。如何让我的MVC控制器将我的JSON Uint8Array反序列化为byte []？

I'm using js-scrypt (https://github.com/tonyg/js-scrypt) on my client-side web application to hash and salt passwords before posting them to my server-side .NET MVC application to be hashed and salted again. This JavaScript library implements byte arrays as JavaScript Uint8Arrays. How do I get my MVC Controller to deserialize my JSON Uint8Array to a byte[]?

JavaScript示例：（AJAX.Post是我写的库，myUint8Array正确序列化）

JavaScript Example: (AJAX.Post is a library I wrote, myUint8Array serializes properly)

AJAX.Post('www.example.com/SendByteArray', { myByteArray: myUint8Array }, Callback);

C＃示例:(在我的默认控制器中）

C# Example: (In my default controller)

[HttpPost]
public async Task<JsonResult> SendByteArray(byte[] myByteArray) {

}

在此示例中myByteArray永远是空的。我尝试了几种不同的方法，基于转换为字符串，然后返回到byte []，但我无法获得正确的值。如果我能够以某种方式直接将代码实现到.NET的JSON解串器中以便上面的代码完全按原样工作，那将是非常优选的，因为我有一些其他项目，如果我可以直接传递字节数组，我可以做一些很酷的事情服务器端和客户端应用程序。

In this example myByteArray is always null. I've tried a couple different approaches based on converting to strings and then back to a byte[] but I haven't been able to get the correct value. It would be greatly preferred if I could somehow implement the code into .NET's JSON deserializer directly so that the code above works exactly as is, because I have a few other projects where I could do some cool things if I could pass byte arrays directly between the server-side and client-side applications.

推荐答案

现在唯一可以使用的方法是base64编码Uint8Array，在C＃中将其捕获为字符串，然后将该字符串转换为byte []。

For now the only method I could get to work was to base64 encode the Uint8Array, capture it as a string in C#, and then convert that string to a byte[].

JavaScript：

JavaScript:

AJAX.Post('www.example.com/SendByteArray', { strByteArray: btoa(String.fromCharCode.apply(null, myUint8Array)) }, Callback);

C＃：

[HttpPost]
public async Task<JsonResult> SendByteArray(string strByteArray) {
    byte[] myByteArray = Convert.FromBase64String(strByteArray);
}
