c# - Get CryptographicException when trying Authorize -


i tried testing web api using microsoft.owin.testing. problem appears when endpoint has attribute "authorize".

for endpoint without attribute it's okay. when try send request authorize endpoint, in stack trace error:

exception thrown: 'system.security.cryptography.cryptographicexception' in system.security.dll

and response has code 401 - unauthorized.

but if start in debug, , testing endpoints in browser (or way) it's okay.

my startup class tests 

 public async void configuration(iappbuilder app) {     var config = new httpconfiguration();     config.includeerrordetailpolicy = includeerrordetailpolicy.always;     config.services.replace(typeof(iassembliesresolver), new resolvercontroller());     diconfig.register(config, app);     oauthconfig.register(app, (oauthsettings)config.dependencyresolver.getservice(typeof(oauthsettings)), (oauthbearerauthenticationoptions)config.dependencyresolver.getservice(typeof(oauthbearerauthenticationoptions)));     webapiconfig.register(config, app); }

and here query endpoint

using (var server = testserver.create<startuptest>()) {     using (var client = new httpclient(server.handler))     {         responce = await server     .createrequest("api/me/token/refresh")     .addheader("content-type", "application/json")     .addheader("authorization", $"bearer {accesstoken}")     .postasync();      } }

here endpoint

[httppost] [route("me/token/refresh")] [authorize] [responsetype(typeof(refreshtokenmodelview))] public ihttpactionresult getrefreshtoken() {     var userid = user.identity.getuserid<int>();     if (userid <= 0) { return notfound(); }     var refreshtoken = _oauthrefreshtokenprovider.createrefreshtoken(userid);      return ok(_mapper.map<refreshtokenmodelview>(refreshtoken)); }

can advise something, ideas?

some screens

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
