需要在web Api2项目.How中获取请求和响应的正文和头部我能做到吗？

public HttpResponseMessage MyAction(HttpRequestMessage request)
{
    // 获取请求的正文
    var requestBody = request.Content.ReadAsStringAsync().Result;

    // 其他处理逻辑...

    return response;
}

public HttpResponseMessage MyAction(HttpRequestMessage request)
{
    // 获取请求的头部
    var headers = request.Headers;

    // 其他处理逻辑...

    return response;
}

public HttpResponseMessage MyAction(HttpRequestMessage request)
{
    // 创建响应对象
    var response = new HttpResponseMessage();

    // 设置响应的正文
    response.Content = new StringContent("Hello, World!");

    // 其他处理逻辑...

    return response;
}

public HttpResponseMessage MyAction(HttpRequestMessage request)
{
    // 创建响应对象
    var response = new HttpResponseMessage();

    // 设置响应的头部
    response.Headers.Add("Custom-Header", "Value");

    // 其他处理逻辑...

    return response;
}
