如何捕捉和保存发布到宁静的asp.net网页API JSON数据 [英] How to catch and save json data posted to restful asp.net web api

问题描述

我有这样的code：

[Route]
    public HttpResponseMessage PostData[FromBody] DataModel data)
    {
         ... implementation...
    }

这自动绑定/ JSON数据转换成我的数据模型。不过，我想保存/赶上被张贴在原始JSON文件并将其保存为日志记录。
我如何能做到这一点有什么建议？

This automatically binds / converts the json data to my data model. However, I would like to save / catch the raw json file that was posted and save it for logging purposes. Any suggestions on how I can achieve this?

推荐答案

您可以做下面的，然后使用JSON转换器将字符串转换成JSON更高版本。

You can just do the below and then use JSON converter to convert the string to JSON later.

[HttpPost]
public HttpResponseMessage PostData([FromBody] string text)
{
   // log text.
    DataModel data = JsonConvert.DeSerialize<DataModel>(text);
}

或者你也可以做到，

Or you can also do,

[HttpPost]
public HttpResponseMessage PostData()
{
    string text = Request.Content.ReadAsStringAsync().Result; 
    //log text           
    DataModel data = JsonConvert.DeSerialize<DataModel>(text);
}

既然你提到它是记录，你可能要考虑在Web API过滤器或委托处理这样做 - 在每一个操作方法，使逻辑更集中，而不是具有逻辑

Since you mention it is for logging, you might want to consider doing this in a Web API filter or a delegating handler - to make the logic more centralized instead of having the logic in each action method.

public class LogApiRequest : ActionFilterAttribute
    {
        public override void OnActionExecuting(HttpActionContext actionContext)
        {
            var text =  actionContext.Request.Content.ReadAsStringAsync().Result;
            MyLogger.Log(LogLevel.INFO, text);

            base.OnActionExecuting(actionContext);
        }
    }

，然后注册您的过滤器 - 通常WebApiConfig.cs或装饰你的操作方法或控制器类与过滤

and then register your filter - typically in WebApiConfig.cs or decorate your action method or controller class with the filter.

config.Filters.Add(new LogApiRequest());
