c# - Securing controller action called from a webjob -


i have mvc web site deployed in azure, need allow users generate pdf file html page. invoking wkhtmltopdf.exe within webjob called controller action. html page rendered produced controller action returns actionresult.

everything works fine when decorate action (that renders html pdf) [allowanonymous] secure somehow.

is possible authenticate request web job or have mysecureaction return data requests originate web job?

here's web job code: 

static void main(string[] args) {   if (args.length == 2)   {     var url = args[0];     var filename = args[1];      try     {       using (var p = new system.diagnostics.process())       {         var startinfo = new system.diagnostics.processstartinfo         {           filename = "wkhtmltopdf.exe",           arguments = url + " " + filename,           useshellexecute = false,         };         p.startinfo = startinfo;         p.start();         p.waitforexit();         p.close();       }        // here save pdf file azure blob storage     }      catch (exception ex) { /*error handling*/ }     }   }

and here's code calls web job: 

string baseurl = request.url.scheme + "://" + request.url.authority +          request.applicationpath.trimend('/'); string url = baseurl + "/mycontroller/mysecureaction/" + id.tostring(); string filename = "filename.pdf";  try {   using (var client = new httpclient())   {     client.baseaddress = new uri("https://myazurewebapp.scm.azurewebsites.net/");     client.defaultrequestheaders.accept.clear();     var username = "$myazurewebappuser";     var password = "myazurewebapppassword";     var encoding = new asciiencoding();     var authheader = new authenticationheadervalue("basic",        convert.tobase64string(    encoding.getbytes(string.format($"{username}:{password}"))));     client.defaultrequestheaders.authorization = authheader;     var content = new system.net.http.stringcontent("");      httpresponsemessage response =   await client.postasync($"api/triggeredwebjobs/mywebjob/run?arguments={url} {filename}", content);      if (!response.issuccessstatuscode)     {        //error handling     }   } } catch (exception ex) {   //error handling }   byte[] file = null; try {   using (var client = new webclient())   {     // retrieve file blob storage     file = client.downloaddata("https://myazureaccount.blob.core.windows.net/pdf/" + filename);   } } catch (exception ex) { /*error handling*/ }  // return file user

and here's action web job calls html

[allowanonymous] public actionresult mysecureaction(int? id) {   somedata model = new somedata();   // data db using id   return view(model); }

this not seem use of webjob. webjobs not invoked web application, nor send requests web app. instead, consider couple alternatives:

you can work directly within app instead of using webjob, isn't buying here.

you can have communication between app , webjob done via queue instead of via direct http messages. e.g. web app adds work item queue, , webjob picks them up, e.g. using webjobs sdk.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
