Attempted with jsreport.Client, I get the 404 error.

Attempted with custom, It downloads the file

I bet its something silly on my end but cant for heaven's sake figure it out :'D .

For now I have gone ahead with the custom implementation. A voice in my head keeps wanting me to figure out the cause of this error :D If you want to get to the bottom of this error as well, I can put in a request for a test user and set up a mirror report and DM you the details.

Please see below, I replicated most of what was available on the jsreport-dotnet-client git

public class JsReportHelper
    {
        public TimeSpan? HttpClientTimeout { get; set; }
        public IContractResolver ContractResolverForDataProperty { get; set; }

        public async Task<Report> RenderAsync(string templateUri, string templateShortid, JObject jsonData)
        {
            JObject root = new JObject();
            JObject template = new JObject
            {
                { "shortid", templateShortid }
            };
            root.Add("template", template);
            root.Add("data", jsonData);
            string request = SerializerHelper.SerializeRenderRequest(templateShortid, jsonData.ToString(), ContractResolverForDataProperty);
            CancellationToken ct = default(CancellationToken);
            var client = new HttpClient();
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", System.Convert.ToBase64String(
                    Encoding.UTF8.GetBytes(String.Format("{0}:{1}", Constants.JsReport_Username, Constants.JsReport_Password))));
            if (HttpClientTimeout != null)
                client.Timeout = HttpClientTimeout.Value;
            var content = new StringContent(root.ToString(), Encoding.UTF8, "application/json");
            var response = await client.PostAsync(templateUri, content, ct).ConfigureAwait(false);


            if (response.StatusCode != HttpStatusCode.OK)
                throw JsReportException.Create("Unable to render template. ", response);

            response.EnsureSuccessStatusCode();

            return await ReportFromResponse(response).ConfigureAwait(false);
        }
        private static async Task<Report> ReportFromResponse(HttpResponseMessage response)
        {
            var stream = await response.Content.ReadAsStreamAsync().ConfigureAwait(false);
            IDictionary<string, string> meta = new Dictionary<string, string>();
            response.Headers.ToList().ForEach(h => meta[h.Key] = h.Value.FirstOrDefault());
            response.Content.Headers.ToList().ForEach(h => meta[h.Key] = h.Value.FirstOrDefault());
            return new ReportHttp()
            {
                Content = stream,
                Response = response
            };
        }
    }

This is how I invoke it

JsReportHelper jsService = new JsReportHelper();
//item.jsreport_url ("https://{host}/reporting/api/report")
//item.jsreport_shortid (js report template id)
//root (JObject)
var report = jsService.RenderAsync(item.jsreport_url, item.jsreport_shortid, root).Result;

I am not sure why but the error with the original code (see below) still persists.

ReportingService service = new ReportingService("https://{host}/reporting/api/report");
//or
ReportingService service = new ReportingService("https://{host}/reporting");

Hey Jan! Yes attempted HTTP Post in C# replicating postman and it works.

A postman call to the link below returns the pdf file

https://host/reporting/api/report

The issue is the JsReport .Net Client package, below is the snippet of code

//ReportingService service = new ReportingService("https://{host}/reporting/api/report");
ReportingService service = new ReportingService("https://{host}/reporting");
service.Username = {username};
service.Password = {password};
using (var fileStream = File.Create(Server.MapPath("~/temp/") + {reportname}+ ".pdf"))
{
          var report = service.RenderAsync({jsreport_shortid}, {data}).Result; //Error pops up here
          report.Content.CopyTo(fileStream);
          Response.ContentType = "application/pdf";
          Response.AppendHeader("Content-Disposition", "attachment; filename=" + {reportname} + ".pdf");
          fileStream.Seek(0, SeekOrigin.Begin);
          fileStream.CopyTo(Response.OutputStream);
          Response.Flush();
          Response.Close();
          Response.End();
}

If I keep just reporting its returns a 404 error

JsReportException: Unable to render template.  <html>
<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
<hr><center>nginx/1.14.0 (Ubuntu)</center>
</body>
</html>

I have 2 enterprise licenses for 2 clients, I had faced the issue before when the path sent was

ReportingService service = new ReportingService("https://host/api/report");

I ended up sending

ReportingService service = new ReportingService("https://host/report");

and it worked for that scenario.

There seems to be an issue with the function call service.RenderAsync which is returning the following error

JsReportException: Unable to render template.  <!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Cannot POST /api/api/report</pre>
</body>
</html>

Its looks like its adding path 'api' twice even though the call sent is

ReportingService service = new ReportingService("https://{host}/reporting/api/report");

Removing 'api' from path works and returns the pdf file only when its the root path but for the scenario above where 'reporting' is the root path it fails.

Thank You! It works :)

Could someone help me figure out why I am not able to access the JSON data in the header template? Please find the example at https://playground.jsreport.net/w/anon/2ze7I7L_
