Asp.Net WebAPI 通过HttpContextBase获取请求参数

public void Post([FromBody]string value)
{
    HttpContextBase context = (HttpContextBase)Request.Properties["MS_HttpContext"];//获取传统context
    HttpRequestBase request = context.Request;//定义传统request对象            
    string name = request.Form["name"];    
}

//获取路由参数
IDictionary<string, object> dic = this.RequestContext.RouteData.Values;
StringBuilder builder = new StringBuilder();
foreach (var item in dic)
{
    builder.AppendFormat("key:{0},value:{1}", item.Key, item.Value);
    builder.AppendLine();
}
return builder.ToString();

////获取表单参数
HttpContextBase context = (HttpContextBase)Request.Properties["MS_HttpContext"];//获取传统context
HttpRequestBase request = context.Request;//定义传统request对象  
StringBuilder builder = new StringBuilder();
foreach (string item in request.Form.Keys)
{
    builder.AppendFormat("key:{0},value:{1}", item, request.Form[item]);
    builder.AppendLine();
}
return builder.ToString();
