Question

如果我从浏览器调用它，请使用无效的web api。

我想用HttpClient来调用它：

 private const string BaseAddress = "http://13.195.151.169:80/VI_ProfilerWebServer/";

    private static readonly HttpClient HttpClient = new HttpClient();



    public static string PostAsJsonAsync(string route, Object jsonConverterParam)
    {

        string result = String.Empty;
        string jsonSerializable = JsonConvert.SerializeObject(jsonConverterParam, Formatting.Indented);
        JObject postContent = JObject.Parse(jsonSerializable);

        try
        {
            var fullRoute = PrepareHttpRequest(route);
            using (HttpResponseMessage response = HttpClient.PostAsJsonAsync(fullRoute, postContent).Result)
            {
                result = response.Content.ReadAsStringAsync().Result;
                DumpUtils.DumpDataToFile(route, fullRoute, postContent, result, response);
                response.EnsureSuccessStatusCode();
            }
        }
        catch (Exception ex)
        {
            throw new HttpRequestException(result, ex);
        }

        return result;
    }
    private static string PrepareHttpRequest(string route)
    {

        HttpClient.DefaultRequestHeaders.Accept.Add(MediaTypeWithQualityHeaderValue.Parse("application/json"));
        string requestUri = BaseAddress + route;
        return requestUri;
    }

此代码在baseurl为http://localhost地址的开发环境中正常工作。但是，只要我将baseUrl更改为http://13.195.151.169:80/VI_ProfilerWebServer/，我就会得到404.如果我使用浏览器并输入说http://13.195.151.169:80/VI_ProfilerWebServer/（代码构造的URI），API调用将按预期工作。

IIS Express仅将默认绑定设置为localhost。但是，您可以通过手动编辑配置文件来更改此设置。

右键单击IIS Express Tray
打开正在运行的应用程序
点击正在运行的应用程序，在底部将显示位于c：\ Users \ USERNAME \ Documents \ IISExpress \ config \ applicationHost.config
再添加一个绑定，如下所示......

＆LT;绑定＆GT;
      ＆lt; binding protocol =＆＃34; http＆＃34; bindingInformation =＆＃34; ：5000：本地主机＆＃34; /＆GT;
      ＆lt;！ - 添加以下行 - ＆gt;
      ＆lt; binding protocol =＆＃34; http＆＃34; bindingInformation =＆＃34; ：5000：*＆＃34; /＆GT;
  ＆LT; /绑定＆GT;

如果我不使用http：// localhost，Http客户端总是返回404
