需要在 web Api2 項目中獲取請求和響應正文和頭部。我該怎么做？

Question

Web Api2項目,,,Controller繼承自另一個控制器,,,,需要獲取json格式的每個請求和響應的body和head

Answer 1

嘗試使用DelegatingHanler攔截請求，如下所示

public class IntercepterMessageHandler : DelegatingHandler
{
    protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
            //try to manipulate the request object

        return base.SendAsync(request, cancellationToken);
    }
}
