After 3 minutes of report creation, still the reports are not getting cleared. You can verify below is the image. These were generated at 12:57 PM and now its way too late. I'm concerned about the server space issue.
The process of creating files on AppData folder and deleting them after 3 mins or after next jsreport run, can't be bypassed?
Absolutley @jan_blaha. I truly appreciate your patience and effort. But in real time i don't want any Temp files getting created on the server. What I expected that on the go it will do the required HTML to PDF file conversion and save them on desired locations.
I'm using .net core 2.0 web app and trying to generate PDF based on the templates saved on the dbase.
There is a concern while generating PDF using jsReport package and C# code. Pdf are getting generated perfectly but i can see some bunch of files getting created on the Server AppData folder. As i was testing this locally i found the files getting created on my local User AppData folder.
I think its not a good pratice to generate files that we don't need. And also these files are not getting cleared. All i want to know is that is there a way to get rid of files that are getting created on AppData floder.
Below is my code config and code shot, jsreport theam can you suggest how to clean up the appdata folder?
Packages details used.
<PropertyGroup>
<TargetFramework>netcoreapp2.0</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="jsreport.Binary" Version="1.10.0" />
<PackageReference Include="jsreport.Local" Version="1.1.2" />
</ItemGroup>
AppData is getting populated with junk data. See the screen shot below.
Actual file folder location after running below code
public static async Task<Tuple<byte[], string, string>> GeneratePDF_Local(string tmplContent, string headerTmpl, string footerTmpl, string content, string fileName, string headerHeight, string footerHeight)
{
try
{
var rs = new LocalReporting()
.KillRunningJsReportProcesses()
.UseBinary(JsReportBinary.GetBinary()).AsUtility().Create();
var report = await rs.RenderAsync(new RenderRequest()
{
Template = new Template()
{
Recipe = Recipe.PhantomPdf,
Engine = Engine.Handlebars,
Content = tmplContent,
Phantom = new Phantom
{
Header = headerTmpl,
Footer = footerTmpl,
Orientation = PhantomOrientation.Portrait,
Format = PhantomFormat.A4,
BlockJavaScript = false,
HeaderHeight = headerHeight,
FooterHeight = footerHeight
}
},
Data = content
});
using (var ms = new MemoryStream())
{
await report.Content.CopyToAsync(ms);
var base64OutputFile = ms.ToArray();
using (FileStream file = new FileStream("E:\\" + fileName + ".pdf", FileMode.Create, FileAccess.Write))
{
//byte[] bytes = new byte[file.Length];
await file.WriteAsync(base64OutputFile, 0, base64OutputFile.Length);
}
await rs.KillAsync();
return new Tuple<byte[], string, string>(base64OutputFile, fileName, FileFormats.ApplicationPdf);
}
}
catch { throw; }
}
Folder on which actual file getting saved see below sceeen
Great response, keep the good work up.These were just some bunch of random observations while doing the POC. Thank you all again.
Observations
Running the project in admin mode.
Code shot:-
Avast Antivirus:-
Conclusion:-
I'm able to download the Pdf file generated from the HTML contents.
Removing Exclusion from Avast antivirus:-
Running the Application and the observation :-
Above are all my observations.
After adding the path of jsreport.exe in the exclusion category inside Avast antivirus console, and removing below two codes i'm able to generate the reports.
var rs = new LocalReporting()
//.RunInDirectory(runExePath)
.KillRunningJsReportProcesses()
//.Configure(cfg => cfg.AllowLocalFilesAccess().FileSystemStore().BaseUrlAsWorkingDirectory())
.UseBinary(JsReportBinary.GetBinary()).AsUtility().Create();
Still i want to know why avast and windows defender behaves like this?
Adding to above issue, observation made while running the project with admin mode, and trying to give jsReport.exe the admin permission i'm getting Windows defender smartscreen alert saying Windows Defender
Windows protected your PC
Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.
App:
jsreport.exe
Publisher:
Unknown publisher
And i'm not able to give the jsreport.exe admin permission.
Is there any way to put this whole observation into some mspaint file or somewhere so that everybody will get the idea.
When i'm adding the jsReport.exe as a trusted file the code works great, seems like some issue on jsReport.exe thing.
Hi great help incredible. But things went the other way around.
I can run the project irrespective of modes(admin/standard user), now i'm getting an error from the antivirus(Avast Free Ware) that i have installed on my workstation. But however if i unchecked the Checkbox to (Scan programs when executing, it's an option in the Avast antivirus dashbord) the code works like a charm.
What I don't understand is that is it good practice to disable "Scan programs when executing," option in the antivirus. Coz when i disable the option, i can run the poc effortlessly. Vice versa is leading to a malware Detect error, avast antivirus recognizing .jsReport.exe as some maleware and removing it after clicking yes to remove.
Also now im getting a popup saying its been submitted to Avast Lab, and soon will be hearing about it.
Hi i'm facing the same issue. However earlier the same piece of code was working like a charm, below are the details.
<PropertyGroup>
<TargetFramework>netcoreapp2.0</TargetFramework>

<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">

Code Snippet. The same i downloaded from your github repo.
https://github.com/jsreport/jsreport-dotnet-example-consoleapp
Running above app gives me an error.
Also i have created a Web API project there also same error persist. Code snippet is below.
Start Up file:
public void ConfigureServices(IServiceCollection services)
{
services.AddNodeServices();
services.AddSingleton<IConfiguration>(_config);
services.AddMvcCore(opt =>
{
opt.OutputFormatters.RemoveType<TextOutputFormatter>();
opt.OutputFormatters.RemoveType<HttpNoContentOutputFormatter>();
})
.AddJsonFormatters() // Adding Json Formatters in Pipeline
.AddDataAnnotations() // Always keep it in config for Model Validation
.AddJsonOptions(opts =>
{
opts.SerializerSettings.ContractResolver = new DefaultContractResolver();
opts.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
opts.SerializerSettings.DefaultValueHandling = DefaultValueHandling.Include;
opts.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
})
.AddMvcOptions(opts =>
{
opts.RespectBrowserAcceptHeader = true;
opts.ReturnHttpNotAcceptable = true;
});
}
