如何添加和获得的WebAPI页眉值 [英] How to add and get Header values in WebApi

问题描述

我需要创建的WebAPI POST方法，所以我可以从应用程序的WebAPI方法发送数据。我不是能得到头值

I need to create a POST method in WebApi so I can send data from application to WebApi method. I'm not able to get header value.

在这里，我已经在申请加入标头值：

Here I have added header values in the application:

 using (var client = new WebClient())
        {
            // Set the header so it knows we are sending JSON.
            client.Headers[HttpRequestHeader.ContentType] = "application/json";

            client.Headers.Add("Custom", "sample");
            // Make the request
            var response = client.UploadString(url, jsonObj);
        }

继的WebAPI POST方法：

Following the WebApi post method:

 public string Postsam([FromBody]object jsonData)
    {
        HttpRequestMessage re = new HttpRequestMessage();
        var headers = re.Headers;

        if (headers.Contains("Custom"))
        {
            string token = headers.GetValues("Custom").First();
        }
    }

什么是让头部值正确的方法？

What is the correct method for getting header values?

感谢。

推荐答案

在Web API的一面，简单地使用请求对象，而不是创造新的HttpRequestMessage

On the Web API side, simply use Request object instead of creating new HttpRequestMessage

     var re = Request;
    var headers = re.Headers;

    if (headers.Contains("Custom"))
    {
        string token = headers.GetValues("Custom").First();
    }

    return null;
