Question

我遇到了WebClient的问题。我正在使用API密钥身份验证，而API密钥确实合法。如果我在我的API上关闭身份验证它会获得数据没有任何问题，但是，如果我在WebClient标头中启用了“身份验证”检查，它会返回一个带有错误/无效API密钥的401，但是有一个有效的API密钥返回错误500。

使用WebClient的代码：

public ActionResult Index()
{
    using (var client = new WebClient())
    {
        client.Headers.Clear();
        client.Headers.Add("Authorization", AppSettings.ApiKey());
        client.Headers.Add("Host", "localhost");
        client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");
        var newsJson = client.DownloadString("http://localhost:59308/Api/ListNews");
        var newsJsonDeserialized = JsonConvert.DeserializeObject<List<News>>(newsJson);
        ViewData["NewsFeed"] = newsJsonDeserialized.ToList();
    }
    var dayMessages = new List<string> { "an astonishing", "an amazing", "a beautiful", "a gorgeous", "a loving" };
    var randomNumber = new Random().Next(dayMessages.Count);
    ViewData["DayOfWeekMsg"] = dayMessages[randomNumber] + " " + DateTime.Now.ToString("dddd");
    return View();
}

ApiController：

public ActionResult ListNews()
{
    using (var db = new Entities())
    {
        var apiToken = Request.Headers["Authorization"];
        var apiTokens = db.ApiTokens.ToList();
        var websiteUrl = Request.Url.Host;
        if (apiTokens.SingleOrDefault(i => i.Token == apiToken && i.WebsiteUrl == websiteUrl) == null)
        {
            return new HttpUnauthorizedResult();
        }
        var news = db.News;
        var newsList = news.ToList();
        return Content(JsonConvert.SerializeObject(newsList, Formatting.Indented), "application/json");
    }
}

提前致谢！

不确定是否是同样的问题，但我收到500并通过设置接受语言标题（使用UserAgent）修复：

client.Headers.Add(HttpRequestHeader.AcceptLanguage, "en");

WebClient在GET请求MVC 5上返回错误500
