有人可以帮我翻译成Alpine命令吗?
按照我当前的配置和堆栈跟踪。
Startup.cs
services.AddJsReport(new LocalReporting() .UseBinary(RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ? jsreport.Binary.JsReportBinary.GetBinary() : jsreport.Binary.Linux.JsReportBinary.GetBinary()) .KillRunningJsReportProcesses() .AsUtility() .Create());
控制器
[HttpGet("generate/{uid}"), Route("generate")] [MiddlewareFilter(typeof(JsReportPipeline))] public IActionResult GenerateReport([FromQuery] Guid uid) { ReportResponseModel model = _reportHelper.Get(uid); HttpContext.JsReportFeature().Recipe(Recipe.ChromePdf) .Configure(c => c.Template.Chrome = new Chrome { Landscape = model.Landscape }); return View(model.ViewName, model.ViewModel); }

问题是jsreport.Binary.Linux持有jsreport binary,而该文件未在高山上编译。也许只是缺少一些导致No such file or directory
的依赖项,但我无法找出哪个依赖项。可能需要在alpine上重新编译二进制文件并将其嵌入到另一个jsreport.Binary.Linux.Alpine
nuget中。
