我想在.net核心中获取Http Request正文,我使用了以下代码:
using (var reader
= new StreamReader(req.Body, Encoding.UTF8))
{
bodyStr = reader.ReadToEnd();
}
req.Body.Position = 0
但是我得到了这个错误:
System.ObjectDisposedException:无法访问已处置的对象。 对象名称:“ FileBufferingReadStream”。
该行的using语句后发生错误
如何在.net核心中获取HttpRequest主体? 以及如何解决此错误?

使用此扩展方法获取httpRequest正文:
public static string GetRawBodyString(this HttpContext httpContext, Encoding encoding)
{
var body = "";
if (httpContext.Request.ContentLength == null || !(httpContext.Request.ContentLength > 0) ||
!httpContext.Request.Body.CanSeek) return body;
httpContext.Request.EnableRewind();
httpContext.Request.Body.Seek(0, SeekOrigin.Begin);
using (var reader = new StreamReader(httpContext.Request.Body, encoding, true, 1024, true))
{
body = reader.ReadToEnd();
}
httpContext.Request.Body.Position = 0;
return body;
}
重要的是HttpRequest.Body是Stream类型,并且在处理StreamReader时,也在处理HttpRequest.Body。
我遇到了这个问题,直到我在github中找到以下链接: 请参阅下面的链接和GetBody方法 https://github.com/devdigital/IdentityServer4TestServer/blob/3eaf72f9e1f7086b5cfacb5ecc8b1854ad3c496c/Source/IdentityServer4TestServer/Token/TokenCreationMiddleware.cs
如果正确,请标记为正确答案。

被接受的答案对我不起作用,但是我正在阅读两次尸体。
public static string ReadRequestBody(this HttpRequest request, Encoding encoding)
{
var body = "";
request.EnableRewind();
if (request.ContentLength == null ||
!(request.ContentLength > 0) ||
!request.Body.CanSeek)
{
return body;
}
request.Body.Seek(0, SeekOrigin.Begin);
using (var reader = new StreamReader(request.Body, encoding, true, 1024, true))
{
body = reader.ReadToEnd();
}
//Reset the stream so data is not lost
request.Body.Position = 0;
return body;
}

简单的解决方法:
using (var content = new StreamContent(Request.Body))
{
var contentString = await content.ReadAsStringAsync();
}
答案 3 :(得分:-1)
对 .NET Core 3.1
使用以下内容Startup.cs
app.Use((context, next) =>
{
context.Request.EnableBuffering(); // calls EnableRewind() `https://github.com/dotnet/aspnetcore/blob/4ef204e13b88c0734e0e94a1cc4c0ef05f40849e/src/Http/Http/src/Extensions/HttpRequestRewindExtensions.cs#L23`
return next();
});
然后您应该能够按照其他答案快退:
httpContext.Request.Body.Seek(0, SeekOrigin.Begin);
