C＃ASP.NET核心web api httprequestmessage重写 [英] C# ASP.NET core web api httprequestmessage rewrite

问题描述

我正在从ASP.NET Web API重写一个POST方法到ASP.NET Core我不知道如何重写下面的代码。此代码在ASP.NET Web API中工作正常。



ASP.NET Web Api：

I am re-writing a POST method from ASP.NET Web API to ASP.NET Core I am not sure how to re-write the below code. This code works fine in ASP.NET Web API.

ASP.NET Web Api:

public IHttpActionResult Post()
{
    var rawds = ConvertByteToArray(Request.Content.ReadAsStreamAsync().Result); //error here at Content
    //do something
}

private byte[] ConvertByteToArray(Stream stream)
        {
            using (MemoryStream ms = new MemoryStream())
            {
                stream.CopyTo(ms);
                return ms.ToArray();
            }
        }

我的尝试：



当我在ASP.NET Core中编写如下相同的代码时，我得到以下错误'HttpRequest'不包含'Content'的定义，也没有扩展方法'Content'接受a可以找到类型'HttpRequest'的第一个参数（你是否缺少using指令或程序集引用？）



ASP.NET核心：

What I have tried:

When I write the same code as below in ASP.NET Core I get the following error 'HttpRequest' does not contain a definition for 'Content' and no extension method 'Content' accepting a first argument of type 'HttpRequest' could be found (are you missing a using directive or an assembly reference?)

ASP.NET Core:

public IActionResult Post()
{
    var rawds = ConvertByteToArrayAsync(Request.Content.ReadAsStreamAsync().Result);
    //do something
} 

public static async Task<byte[]> ConvertByteToArrayAsync(Stream stream)
        {
            using (var ms = new MemoryStream(2048))
            {
                await request.Body.CopyToAsync(ms); //get error here at request
                return ms.ToArray();
            }
        }

推荐答案

await request.Body.CopyToAsync(ms);

1.无论如何，它应该是Request（R而不是r）！

2.似乎是一个逻辑错误，你将'Result'流传递给函数但不使用它？你可能想把它复制到ms？

1. In any case it should be Request (R and not r)!
2. It seems to be a logic error, that you pass the 'Result' stream to the function but do not use it? You probably meant to copy it to ms?
