客户端如何在 C# 中将二进制数组数据发送到服务器

发布于 2024-12-11 06:01:54 字数 451 浏览 0 评论 0原文

我正在尝试使用 HttpWebRequest 在 C# 中发布 byteArray。我不想将字节转换为字符串（或 ToBase64String）。我只想将 byteArray 按原样发送到服务器。假设我的数据

byte[] byteArray = { 0, 1, 5, 4, 0, 1, 55, 0, 1, 5, 4, 0, 1}

应该在后参数中定义什么？

request.ContentType = "application/x-www-form-urlencoded"??? or request.ContentType = "application/octet-stream";???

我想我错过了一些大东西......（顺便说一句，服务器是WampServer（Koana，PHP，MySQL）

谢谢！

I am trying to use the HttpWebRequest for posting a byteArray at C#. i dont want to convert the bytes to string (or to ToBase64String). i just want to send the byteArray to the server as is. let say that my data is

byte[] byteArray = { 0, 1, 5, 4, 0, 1, 55, 0, 1, 5, 4, 0, 1}

what should i define at the post parameters?

request.ContentType = "application/x-www-form-urlencoded"??? or request.ContentType = "application/octet-stream";???

I think I am missing something big....(BTW, the server is WampServer (Koana,PHP,MySQL)

Thanks!

更简单的方法是使用 WebClient：

byte[] byteArray = { 0, 1, 5, 4, 0, 1, 55, 0, 1, 5, 4, 0, 1};

using(WebClient wc = new WebClient())
{
    wc.UploadData(someURL, byteArray);
}

对于二进制数据，您通常会使用 application/octet-stream - 但这不是必需的（取决于服务器） )，即上面的 WebClient 上传没有指定内容类型标头。

An easier way to do this would be to use a WebClient:

byte[] byteArray = { 0, 1, 5, 4, 0, 1, 55, 0, 1, 5, 4, 0, 1};

using(WebClient wc = new WebClient())
{
    wc.UploadData(someURL, byteArray);
}

For binary data you usually would use application/octet-stream - but this is not required (depends on the server), i.e. the WebClient upload above does not specify a content-type header.

 byte[] byteArray = { 0, 1, 5, 4, 0, 1, 55, 0, 1, 5, 4, 0, 1}

 using (Stream requestStream = httpWebRequest.GetRequestStream()) {
     if (requestStream.CanWrite)
         requestStream.Write(byteArray, 0, postBytes.Length);
 }

 byte[] byteArray = { 0, 1, 5, 4, 0, 1, 55, 0, 1, 5, 4, 0, 1}

 using (Stream requestStream = httpWebRequest.GetRequestStream()) {
     if (requestStream.CanWrite)
         requestStream.Write(byteArray, 0, postBytes.Length);
 }
