c# - Best practices for passing Access Token to Web API to perform calls on behalf of user -


disclaimer: first time dealing oauth.

i'm setting web api middleman between user (using mobile application), , xero public application.

for user access xero data, must first authenticate xero public application. user supplied access token , access token secret @ end of authentication process. done via oauth 1.1.

at point, mobile application has access token , access token secret - supplied xero public application. point user never talk xero public application again.

what need have user send post web api contains xero username , xero access token (and possibly xero access token secret). web api controller receive request, , send request xero public application ensure works.

when ok response has been received xero public application, web api register user storing user (with xero username), , organisation (with access token + secret) in database.

at point, necessary credentials stored in web api database, , web api controllers can perform requests on behalf of user. entire reasoning behind web job can set pull xero data web api once or twice day, , user ever accesses data.

my questions are:

  • are there red flags here?
  • do need provide access token between user/mobile application , web api? given device, or user?
  • owin can provide access tokens, i'm unsure how should using them between mobile application <-> web api.

thanks in advance.

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 ...
