API 404混淆了混乱

Question

尝试进行生成pdf的调用，返回字节。尽管谷歌持续了好几个小时，但我仍然得到404并且无法纠正这种情况。我尝试了很多不同的东西，这有点乱。感谢。

Global.asax中

    RouteTable.Routes.MapHttpRoute(
        name: "PdfApi",
        routeTemplate: "global/api/pdf/{controller}",
        defaults: new { id = RouteParameter.Optional });

       using (var client = new HttpClient() { BaseAddress = new Uri(this.BaseAddress + "/global/api") })
        {
            //client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));

            //var response = client.GetAsync(UrlParameters).Result;
            var x = new List<KeyValuePair<string, string>>();
            foreach(string key in this.QueryString.Keys)
                x.Add(new KeyValuePair<string,string>(key, this.QueryString[key]));

            var response = client.PostAsync("/pdf/GeneratePdf", new FormUrlEncodedContent(x)).Result;

            return response.IsSuccessStatusCode ? response.Content.ReadAsAsync<byte[]>().Result : null;
        }

//[RoutePrefix("global/api/pdf")]
public class PdfController : ApiController

    public class Pdf
    {
        public bool BreakImage { get; set; }
        public bool BreakText { get; set; }

        using (var client = new System.Net.WebClient())
        {
            html = client.DownloadString(pdf.SourceUrl + "?pdf-printable=true");
        }

        try
