Question

一直在努力学习API几天，发现它有点困难，但设法通过阅读相当多的帖子来鼓励这个：

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "ID,domain,contact,contactname,price,type,TF,CF,RI,MJTopicsID,UserTableID")] Identifier identifier)
{
    if (ModelState.IsValid)
    {
        db.Identifiers.Add(identifier);
        db.SaveChanges();
        return RedirectToAction("Index");
    }

    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(
    "https://api.majestic.com/api/json?app_api_key=KEY&cmd=GetIndexItemInfo&items=1&item0=http://www.majestic.com&datasource=fresh");

    {
        WebResponse response = request.GetResponse();
        using (Stream responseStream = response.GetResponseStream())
        {
            StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
            string json2 = reader.ReadToEnd();
            MajesticData r = JsonConvert.DeserializeObject<MajesticData>(json2);
        }

        ViewBag.MJTopicsID = new SelectList(db.MJTopicss, "ID", "ID", identifier.MJTopicsID);
        ViewBag.UserTableID = new SelectList(db.UserTables, "ID", "userIdentity", identifier.UserTableID);
        return View(identifier);
    }
}

然后我使用http://json2csharp.com/创建模型并将RootObject更改为MajesticData。我在我的I中初始化了表，然后在控制器的[httpPost]创建操作中运行它，尽管创建操作很好并且它将数据提交到标识符表并返回视图，但是没有数据提交给MajesticData模型或其他？

使用保存更新：

    public ActionResult ApiCall()
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.majestic.com/api/json?app_api_key=KEY&cmd=GetIndexItemInfo&items=1&item0=http://www.majestic.com&datasource=fresh");
        {
            WebResponse response = request.GetResponse();
            using (Stream responseStream = response.GetResponseStream())
            {
                StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
                string json2 = reader.ReadToEnd();
                Datum newdata = JsonConvert.DeserializeObject<Datum>(json2);
                db.Datums.Add(newdata);
                db.SaveChanges();
            }
        }
    }

一旦从json构造MajesticData对象，就会丢弃它。您需要一些代码从中提取数据并将其放在ViewBag中（或将其写在其他地方）。

但我会说，如果ModelState无效，你只会调用API确实很奇怪......

.NET API请求未保存到数据库
