"404 - File or directory not found." when run FastReport.NET under an IIS Application: Web
I am testing the FastReport.NET Trial Version.
I have an ASP.NET Core 2 aplication deployed under an IIS Application: WebSite/WebApplication
When I run a FastReport.NET report I get:
Server Error
404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.
and using developer tools in browser I see multiple errors like this one:
HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier).
(XHR)GET - http://server:8001/_fr/preview.getReport?r...;renderBody=yes
I have tried to change RouteBasePath to "/WebApplication/_fr" and this time I get:
Error
404 - Not Found
and using developer tools in browser I see multiple errors like this one:
HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier).
(XHR)GET - http://server:8001/WebApplication/_fr/prev...;renderBody=yes
If I move the ASP.NET app into the root Application of the IIS WebSite or run it under VS2017 IIS Express everything works fine.
How to make it function under WebSite/WebApplication ?
Thank you

The link url is not working.
What was your workaround solution please? I try inject basepath into HTML/script rendered by fastreport, but after that in page there are additional ajax calls and urls are wrong.
Thanks.
hey, have any progress? cuz I got the same problem...
you must have source code to fix the bug
To get the Web Root Path try
In Core 2.0
public class HomeController : Controller
{
private readonly IHostingEnvironment _hostingEnvironment;
..........
public HomeController(IHostingEnvironment hostingEnvironment)
{
_hostingEnvironment = hostingEnvironment;
}
....In your code... Index()
string webRootPath = _hostingEnvironment.WebRootPath; // Get the path to wwwroot folder
In Core 3 and higher try
public class HomeController : Controller
{
private readonly IWebHostEnvironment _hostingEnvironment;
..........
public HomeController(IWebHostEnvironment hostingEnvironment)
{
_hostingEnvironment = hostingEnvironment;
}
....In your code... Index()
string webRootPath = _hostingEnvironment.WebRootPath; // Get the path to wwwroot folder
Hello,
i´m using the current Demo-Version for evalutaion and do have the same problem. Can you please give an solution how to inject the correct path into html or give another solution? I try to use it with AspNet Core 3.1
best regards

Asp.net Core 2.2 single page application, dont forget to copy folder "Reports" to publish folder😀
Asp.net Core 3.1 single page application, dont forget to copy folder "Reports" to publish folder
<ItemGroup> <Content Include="Reports\**"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> </Content> </ItemGroup>Hello ipong,
thanks for your fast help :)
i modified following lines:
// string basePath = Request.PathBase.Value.Replace("/", "");
string basePath = Request.PathBase.Value;
if (basePath.StartsWith("/"))
{
basePath = basePath.Substring(1);
}
With this the injection works on a folder-Structure like https://localhost/test/test2 on IISExpress
When i deploy this to an IIS (windows 2016) into an subfolder test i get an 500-Error on the request
_fr/preview.getReport?reportId=cf6af2189d4e4a389adaa8d382bc252e&renderBody=yes
Do you have an idea?
best regards

just change :
string basePath = Request.PathBase.Value.Replace("/", "");
to :
string path = Request.PathBase.Value;
string basePath = path.Length == 1 ? "" : path.StartsWith("/") ? path.Substring(1) : path;
Hello Ipong,
thanks for your help.
i changed the code to your sample above - but there is still the http 500-Errorcode at _fr/preview.getReport?reportId=f7d249dbc88145879202c6a1f0a54cc5&renderBody=yes:1
Do you have another idea? Maybe one topic is, that directory test2 is converted to an Web-Application?
best regards

rewrite the code, much cleaner...
[HttpPost("Report")]
[Route("Report")]
public ModelFastReport Report([FromBody] ModelDemo value)
{
try
{
DataSet data1 = LoadData1();
List<Category> data2 = LoadData2();
FastReport.Web.WebReport wr = new FastReport.Web.WebReport();
string frx = Path.Combine(_env.ContentRootPath, "reports", value.file);
wr.Report.Load(frx);
wr.Report.RegisterData(data1, "NorthWind");
wr.Report.RegisterData(data2, "Categories BusinessObject");
foreach (FastReport.Data.DataSourceBase item in wr.Report.Dictionary.DataSources)
{
item.Enabled = true;
}
string basePath = Request.PathBase.Value;
return new ModelFastReport() { id = basePath, html = FastReportHtml(basePath, wr.ID, wr.RenderSync().Value) };
}
catch (Exception ex)
{
return new ModelFastReport() { id = "", html = ex.ToString() };
}
}
private string FastReportHtml(string basePath, string token, string htmlString)
{
string oldCssOutline = string.Format(".fr{0}-outline {{", token);
string newCssOutline = string.Concat(oldCssOutline, "color: black;");
string oldAjax = "container.outerHTML = xhr.responseText";
string newAjax = string.Format("{0}.replace(\"{1}\", \"{2}\").replace(/\\/_fr/g, \"{3}/_fr\")", oldAjax, oldCssOutline, newCssOutline, basePath);
string oldCssProgress = "style=\"min-height:200px\">";
string newCssProgress = string.Format("><img src=\"{0}/progress.gif\">", basePath);
string OldCssSpinner = string.Format(".fr{0}-spinner {{", token);
string NewCssSpinner = string.Concat(OldCssSpinner, "display: none;");
string oldCssBackgroundColor = "background-color: white;";
return htmlString.Replace("/_fr", basePath + "/_fr").Replace(oldCssBackgroundColor, "").Replace(oldCssProgress, newCssProgress).Replace(OldCssSpinner, NewCssSpinner).Replace(oldAjax, newAjax);
}
but...when you have a report with picture inside, 'print from browser' will not work. thats why in my previous comment, i said "you must have source code to fix the bug"
here is the fix for 'print from browser'
Hello Ipong,
thanks for your hint.
i had to publish a selfcontained deployment because on the IIS server is only the .Net Core Hosting-Package installed - but the Solution requires The framework 'Microsoft.WindowsDesktop.App', version '3.1.0' was not found..
i think this comes from the used Core3-Assemblies. It is possible to get a version, which runs with the .Net Core-Hosting-Package?
best regards
i got the same error, must downgrade to .net core 2.2 => FastReport.Core.2021.1.7-demo.nupkg & FastReport.Web.2021.1.7-demo.nupkg
