在WebApi Core ActionFilter中将请求体作为字符串获取吗？
在WebApi Core ActionFilter中将请求体作为字符串获取吗？
提问于 2017-11-22 07:27:34
下面是我在WebApi .Net Core 2项目中的.Net：
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public class RequestLoggingAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext actionContext)
{
var request = actionContext.HttpContext.Request;
var route = request.Path.HasValue ? request.Path.Value : "";
var requestHeader = request.Headers.Aggregate("", (current, header) => current + $"{header.Key}: {header.Value}{Environment.NewLine}");
request.EnableRewind();
var requestBody = new StreamReader(request.Body).ReadToEnd();
}
}requestHeader有正确的值，它是可以的，但是requestBody总是空的。
我用下面的正文向操作发送请求来测试它。
[
{
"TrackingCode": "96003445",
"Description": "",
"InnerMessage": "",
"Status": 11
},
{
"TrackingCode": "96003840",
"Description": "",
"InnerMessage": "Inner message",
"Status": 11
}
]如何在WebApi核心2 ActionFilter中获得请求体？

有了@Nkosi指南，我可以找到如下解决方案：
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public class RequestLoggingAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext actionContext)
{
var request = actionContext.HttpContext.Request;
var route = request.Path.HasValue ? request.Path.Value : "";
var requestHeader = request.Headers.Aggregate("", (current, header) => current + $"{header.Key}: {header.Value}{Environment.NewLine}");
var requestBody = "";
request.EnableRewind();
using (var stream = new StreamReader(request.Body))
{
stream.BaseStream.Position = 0;
requestBody = stream.ReadToEnd();
}
}
}它工作得很好
